<p><strong>Objective: </strong>The aim of this systematic review was to determine the effects of cluster training on muscle<br />hypertrophy.<br /><strong>Methodology: </strong>A literature search was performed in the electronic databases Pubmed, Scopus and Web of Science,<br />using the following keywords: “cluster training”, “rest interval”, “rest pause”, “hypertrophy”, “resistance training”<br />and “cross sectional area”. We included clinical trials that used cluster training as an intervention in people over 18<br />years of age of both sexes.<br /><strong>Results: </strong>The systematic review obtained during the search of the databases consulted yielded a total of 23 potentially eligible articles, of which a sample of 9 was taken from which results could be obtained that responded to the objective of this review. The number of participants from the 9 eligible articles was 172 subjects. Cluster workouts allow for increased training volume and intensity without causing high levels of fatigue, thus favoring the development of muscle<br />hypertrophy.<br /><strong>Conclusions: </strong>The results of this systematic review suggest that cluster training can be an effective tool for the development of muscle hypertrophy.</p>

<p>Introduction: Genetic component has been established<br />as a significant risk factor for anterior cruciate<br />ligament rupture (ACLR). Current research has focused<br />on knowing the candidate genes that can influence<br />and predispose a subject to this injury. Objective:<br />A bibliometric analysis was carried out to trace the<br />results of the research and identify global trends and<br />gaps in knowledge about the relationship between<br />the genetic component and ACLR. Methodology: Data<br />were extracted from the Pubmed and Scopus databases<br />and analyzed in the Bibliometrix package of the R<br />software. A total of 63 studies published since 2007<br />were identified. Results: Most of the publications recovered<br />were research articles (85.71%). The authors<br />with the highest number of those are in Poland and<br />South Africa. The analysis through the co-occurrence<br />map reveals that there is a mainline of research based<br />on the study of genetic polymorphisms, especially in<br />the genes of the collagen families (COL1A1, COL5A1,<br />COL12A1, in greater frequency). A total of 54 candidate<br />genes were identified within the studies. Conclusion:<br />We hope that this study can help to find key<br />points and research gaps by providing a comprehensive<br />analysis and structured information on this topic.</p>

<p>Introduction: The variables determinants of physical performance in cross-country marathon of mountain biking (XCMMTB)<br />are still unknown.<br />Objective: We aimed to verify the training control variables and the physiological responses in an official XCM-MTB race.<br />Material and methods: 13 athletes (11 men and 2 women; 33.3 ± 12.7 years of age) participated in this study. It was<br />conducted during an official XCM-MTB in Brazil (route of 70 km). The heart rate (HR), altimetry, velocity, temperature,<br />pacing, and power were obtained every 10 km travelled by the STRAVA application. Multiple linear regression analysis was<br />performed to verify whether the variables could predict physical performance.<br />Results: The athletes maintained constant HR elevation in the corresponding zone 80% HRmax. They also presented a<br />variation in the pacing (F = 35.82; p < 0.001; d = 0.66) and power (F = 7.20; p < 0.001; d = 0.18) showing higher values in the<br />last 10 km. Only pacing can be considered a predictor of the physical performance (β = 0.958; t = 7.30; p < 0.001), specifically<br />the one at 20 km (F = 10.23; p = 0.004; R2 = 0.82).<br />Conclusion: The study concluded that the analyzed variables are reliable for the performance control in an official XCMMTB<br />race. HR and power are variables that can be used to prescribe and control training, as they change according to the<br />requirements of the race. Power can also be used as a performance predictor as it is directly influenced by terrain.</p>

<p><strong>Purpose:</strong> To explore and discuss theoretical and practical scientific literature to compare sports diversification and early sports specialization as a sport and educational approach.</p> <p><strong>Methods:</strong> A systematic review was conducted following PRISMA guidelines, and 61 studies were included.<br><strong>Results:</strong> Coaches, parents, and children consider that the best way to develop sports talent and enter the elite in sports is to practice a single discipline as early as possible to achieve specialization and maximum technical skills and physical and psychological conditions. Sports specialization paths may lead to a physical, social, and mental state that compromises their integral development.<br><strong>Conclusion:</strong> Sports diversification should be considered first at an early age and, afterward, the specialization once the bases of strength, conditioning, neuromuscular training, and a specific psychomotor maturation have been achieved, so that sports performance and health are not compromised in the medium or long term. It is necessary to consider that few children enter elite sports, so for many of them, sports education will be the basis for exercising their citizenship as active people.</p>

<p><strong>Purpose:</strong> To analyze the psychometric characteristics of the Wagnild and Young Resilience Scale Argentine version in a Costa Rican elderly group.<br><strong>Materials and methods:</strong> The study had two groups, one for the pilot study (N = 40, X = 69.38), and another for the analysis of the psychometric properties (N = 100, X = 69.31). The 25- item Wagnild and Young Resilience Scale, Argentine version, was used. An analysis by expert judgment and a pilot study were carried out to establish the scale to be validated, after which, the complete validation study was carried out. Factor<br>analyzes and Cronbach’s alpha were applied.<br><strong>Results:</strong> They were obtained two factors named: a) “selfefficacy capacity”, and b) “purpose in life capacity”. The global internal consistency was 0.84, for the first factor was 0.81 and for the second factor was 0.74.<br><strong>Conclusions:</strong> The scale generated is reliable and valid to assess resilience in an elderly people with similar characteristics to the present study. In the future, it is recommended to carry out qualitative analyzes to better define the constructs based on the characteristics of the population.</p>

<p>Regional anthropometry turns out to be an important procedure in the projection of the athlete’s performance. The objective of the present study is to relate the anthropometric characteristics of the lower limbs of the body with the jumping power of young athletes. A correlational methodology was used to evaluate 44 youth athletes (30 men and 14 women). They were measured for jump height in 90° squat (SJ), countermovement with fixed hands (CMJ-MF), and countermovement with free hands (CMJ-ML). These variables derived into the power calculation. With this, we established the anthropometric characteristic of lower body parts linked to skinfolds and perimeters, obtaining values of mid (MMED) and maximum thigh (MMAX), corrected calf perimeter (PCP), quadriceps muscle section area (ASMC), hamstring muscular section area (ASMI), and total section of the muscular thigh area (ASMM). The results showed a significant correlation between the corrected calf perimeter and the jump power in SJ (<em>r</em>=0.73; <em>p</em>=0.00), CMJ-MF (<em>r</em>=0.72; <em>p</em>=0.00) and CMJ-ML(<em>r</em>=0.7; <em>p</em>=0.00). In conclusion, the calf perimeter presented related components to the young athletes’ jumping power.</p>

<p>Currently, studies around the organization of training processes through tasks have become one of the emerging lines in Sports Sciences. Therefore, the present paperwork aimed to analyze the way of acting of a technical body of a soccer team in school age, U12, as well as to know the relationship of the <em>means of initiation to training</em> and the <em>pedagogical</em>, <em>external load,</em> and <em>organizational </em>variables that influence the design of homework. For this, a total of 177 training tasks framed during five competitive months were examined. In order to categorize the tasks, the <em>Comprehensive System for the Analysis of Training Tasks</em> was used to study the variables identified by the technical staff. A descriptive and difference analysis was conducted of the variables proposed in the study with the <em>training initiation medium</em>. The results demonstrated the existence of associations between the <em>training initiation medium</em> and the variables <em>game situation</em>, <em>game phase</em>, <em>content-type</em>, <em>specific content</em> (<em>pedagogical</em>). Associations were also identified/found in the variables density, number of simultaneous performers, competitive load, game space, and cognitive involvement (external load), and the participation variable (organizational). Associations were also found in the variables <em>density</em>, <em>number of simultaneous performers</em>, <em>competitive load</em>, <em>game space, and cognitive involvement</em> (<em>external load</em>), and the <em>participation </em>variable (<em>organizational</em>). Therefore, these results show the importance of knowing the restrictions related to the workload of training tasks. In addition, they provide the technical body with information on an easy, affordable, and informative tool to quantify workload. This method should be considered as a complement to portable devices for training load control and monitoring in invasion sports.</p>

<p>There is currently an increase in inertial flywheel application in strength training; thus, it must be monitored by an accurate and reliable device. The present study tested: (1) the accuracy of an inertial measurement device (IMU) to correctly measure angular velocity and (2) its inter-unit reliability for the measurement of external load. The analysis was performed using Pearson Correlation and Intraclass Correlation Coefficient (ICC). The IMU accuracy was tested using Bland-Altman and the reliability with the coefficient of variation (CV). Ten elite-level football players performed ten series of 5 repetitions in a one-hand standing row exercise (5 series with each arm). A nearly perfect accuracy (ICC=.999) and a very good between-device reliability (Bias=-.010; CV=.017%) was found. IMU is a reliable and valid device to assess angular velocity in inertial flywheel workout objectively.</p>

<p>Schoolchildren can spend around 80% of their school day sat. In this sense, different studies establish a direct relationship between posture and health problems. Moreover, writing difficulties can also affect the perception of abilities, hence the importance of instilling proper postural and graphomotor habits from an early age. The main objectives of this study were, on the one hand, to design instruments for observation and data collection of postural and graphomotricity patterns and, on the other hand, to validate these instruments through expert opinion. A secondary objective was to evaluate the internal consistency of the instrument to assess the posture of sedestation. Concerning the first objective, both instruments showed high inter-judge concordance in terms of relevance and precision of the items. In relation to the second objective, the instruments were applied to a sample of 93 children from the 1st and 5th grades of primary school to evaluate their internal consistency of the posture instrument. Dimensional reliability results showed values greater than 0.7. The instruments designed are presented as useful tools to assess the patterns related to posture and graphomotricity and thus contribute to detecting problems associated with school-age children. In conclusion, these instruments can provide appropriate guidelines for the development of work plans to meet the needs of students.</p>

<p>The COVID-19 disease is an emerging pandemic challenge, which has physical and psychological repercussions, deteriorating the quality of life in those who have been infected and, in turn, in those who have had to live in confinement. The objective of this study is to know the perceptions of Slackline athletes regarding the effects on training and quality of life derived from the COVID-19 situation. The research is based on a cross-sectional exploratory-descriptive quantitative method. The instrument used was a self-applied survey with three dimensions; 229 people from 28 countries correctly answered it, 176 men (15 - 57 years) and 51 women (20 - 43 years), belonging to Europe, America, Asia, and Oceania. The results show that 97.8% say they have lost motivation, 60.2% declare they have poor infrastructure conditions and / or little access to their training places, 65.5% have financial problems, and 88.2 % have presented health problems, highlighting that 10% of those surveyed have been diagnosed with positive COVID-19. It is concluded that the confinement and pandemic situation has created an unfavorable environment for Slackline athletes due to the complications to carry out their training sessions, lack of access to public spaces, demotivation, loss of physical capacity, and increase in injuries.</p>

<p>Soccer has generated endless research that has enhanced athlete’s qualities to achieve maximum sports performance. According to the above, the use of new tools has been implemented to improve talent selection processes and develop physical abilities, as is the case with dermatoglyphics that provides information on an individual’s genotype. The present study aims to relate body composition, dermatoglyphics, and maximum oxygen consumption in soccer players’ category sub-20. The research had a quantitative, non-experimental, cross-sectional design. The sample comprised 22 players (age 18±1.1) from Bogota Sports Club, Colombia. They were assessed for body composition, the somatotype was calculated, handprints were analyzed, and the maximum oxygen consumption was measured with the Test Course Navette. The results show a predominance of balanced mesomorph somatotype (53%), high presence of “L” ridges (66.36 %), low presence of “A” arches (1.82%), and maximum oxygen consumption of 53.76±3.73 ml/kg/min. Furthermore, significant relationships were found between D10-SCTL dermatoglyphic components and the endomorph somatotype (p <0.05), and between the maximum VO₂ with endomorph and ectomorph somatotype (p <0.05). It is concluded that soccer players are characterized by having a predisposition towards coordination, resistance, and agility.</p>

<p>This study aimed to find changes in the wellness state, during the confinement period due to COVID-19, in professional soccer players from the first division B of Chile. The studied sample consisted of 28 professional male soccer players aged 26 ± 6.3 years, body mass 74.2 ± 5.5 kg, and height 177 ± 0.05 cm. The degree of well-being was evaluated through a questionnaire (McLean et al., 2010) during the 2020 competitive and confinement periods. Statistically, significant differences (p <0.05) between the competitive period and the confinement period are shown in FT (t = 2.5; p = 0.0), SO (t = 2.71; p = 0.01), ES (t = 5.07; p = 0.0), EA (t = 1.82; p = 0.08), and T (t = 4.87; p = 0.0). Small TE were reflected in the variables EA and DM (d = 0.7; d = 0.4 respectively), moderate in FAT and SO (d = 1.0; d = 1.2 respectively), and very large in ES and T (d = 2.1; d = 2.0 respectively). The CP and CV between periods for the well-being variables were the following: for FAT, 11% and 11.6%, for DM, 5.3% and 13.1%; for SO, 9.3%; 7.5%, ES 11.6% and 5.9, for EA 3.9%; 5.2%, and finally for T 8.1% and 4.0% respectively. It is possible to conclude that the state of well-being in professional soccer players is altered in the period of confinement with respect to that of competition, finding significant changes in the variables FT, SO, ES, and T, which coincided with the changes from moderate to very large of these same variables, as well as the PC were larger than the CV between periods. Therefore, we could consider these changes as real, and they could be an effect attributable to the mandatory isolation.</p>

<p>This study focuses on the analysis of perceived effort and time of moderate and vigorous activities in physical education classes, considering differences based on gender and the nutritional status of schoolchildren. A total of 95 children in 5th and 6th grade of primary school in the city of Coyhaique, Chile, participated in the study. The EPInfant scale was used to assess the perceived effort, and Actigraph GT3X+ accelerometers were used to determine the time of moderate and vigorous activity. No significant differences were found in the perceived effort by gender (<em>p</em>=0.144); instead, by nutritional status, obese students indicated a higher perceived effort than students with a normal weight (<em>p</em>=0.220). Regarding moderate and vigorous activities in Physical Education class, the boys were significantly more active than the girls (<em>p</em>=0.017). In contrast, normal-weight children were slightly more active at this intensity level, but this difference was not statistically significant (<em>p</em>=0.622). The effort in Physical Education classes has been perceived as more demanding by the obese students; for this reason, it is important to understand the physical and motor difficulties that this group presents. Likewise, girls have participated for a shorter time in moderate and vigorous intensities, being pertinent to look for didactic strategies to increase the time of their participation.</p>

<p><strong>Objective</strong>: From a socio-historical approach with emphasis on the social history of knowledge and experts, the following scientific work analyzes the XIV Pan American Congress of Physical Education held in Costa Rica in 1993. The paper analyzes the event as a space for sociability, knowledge circulation, legitimation of certain experts, influence, and power of some international organizations. Based on this analysis, the article aims to examine the knowledge, experts, and organizations that validated certain true meanings on how to conceptualize the vast universe of physical culture, physical education, and sports. <strong>Material and methods</strong>: To conduct the hermeneutical analysis within the framework of a qualitative methodology. Interpretive attention has been focused on various documentary sources, such as memoirs and reports of the congress, the written press, the central exhibitions, the general lectures, and the memories related to other Pan American congresses. Likewise, a set of semi-structured interviews have been carried out. The analysis has articulated the “text” with the historical conditions of production and interaction of the investigated universe. <strong>Results and conclusion</strong>: Among the conclusions, the congress is identified as a space in which the educational discipline was questioned through various types of knowledge, highlighting the biomedical, pedagogical, didactic, and sociological ones. In addition, the congress made visible certain international experts and important transnational institutions linked to the heterogeneous field of physical culture.</p>

<p>This study aims to analyze the reliability of the test of 8 throws of 3 different variants of handball throws in university students. The participants were 33 males, 20 ± 1.9 years; weight 72.39 ± 8.9 kg; height 176.75 ± 6.07 cm; BMI 23.14 ± 2.3. They were evaluated in 2 sessions separated from each other by a period of one week. The participants executed throws until 8 measurements were recorded in each of the tests, unspecific throws, in support and in the race with 3 steps; the launch speed was recorded with a radar behind the goal. The reliability of the average of the test scores of 8 measurements between the first session and the second was measured with a test-retest test. The following results were obtained: in the nonspecific launch, an ICC= (0.86) was obtained between 95% of confidence, one of CV= (7.43%) and one ES = (0.08). For the toss with support, an ICC = (0.94) was obtained at 95% confidence, one of CV = (4.71%) and an ES = (-0.09). For the running throw, an ICC = (0.96) was obtained at 95% confidence, one of CV = (4.00%) and one ES = (0.05). This study has shown that the test of 8 throws and the 3 variants is a reliable and stable performance measure for university-level students without experience in handball; in relation to the throw variables, all 3 were reliable. Only the nonspecific variable was lower compared to the supported and running pitch.</p>

<p>The quantification of training load has become mandatory for coaches and team staff. Within the analyzed variables, distance covered at different speed zones is one of the most studied. However, there is no consensus in the definition of speed zones in the published articles about each team sport, so it makes difficult a comparison between them. Therefore, the purposes of this article were to establish a criteria standard in the classification of speed zones in team sports and to analyze its practical application in basketball. Five speed categories were established for basketball following the methodology described above: 0-10km/h, >10-13.8 km/h, >13.8-17.6 km/h, >17.6-21.5 km/h, and >21.5 km/h. The results showed differences between periods in high-speed displacements and sprints, maximum speed, total decelerations, and accelerations. In conclusion, the categorization of workload based on standard deviation according to maximum speed could be a viable option to individualize the analysis of distance covered per speeds in team sports such as basketball. Its use may lead to a better understanding and contextualization of the locomotion data in specific sports and teams.</p>

<p>Aerobic exercise (AE) has been shown to be beneficial for the survival of patients with CAD and the decrease in interleukin 6 (IL-6). However, there is little evidence of the effect of concurrent training (CT). <strong>Purpose:</strong> To analyze the effect of AE versus CT on IL-6 in patients with CAD. <strong>Methodology:</strong> It was developed based on the PRISMA agreements; scientific articles were searched through electronic databases. The search terms (Boolean phrase) were the following: ("coronary artery disease" OR '' cardiac disease '' OR "cardiovascular disease") AND ('' exercise '' OR '' training '' OR "cardiac rehabilitation") AND ("IL-6" OR "Interleukin-6" OR "inflammatory markers") NOT ("animals" OR "rat"). The searches were conducted between August and December 2019. <strong>Results:</strong> A total of 2516 studies were reviewed, of which 10 studies that met the eligibility criteria were included. A total of 413 patients were analyzed. An improvement was found between 5% and 74% with the AE and between 2.3% and 58.8% with the CT. Both modalities significantly decrease IL-6, regardless of age, weekly training sessions, and the initial stage of patients with CAD; however, those studies that used a high intensity or a volume greater than 30 minutes showed greater benefits. <strong>Conclusion:</strong> Both EA and CT are beneficial in reducing IL-6 in patients with CAD. This systematic review leaves the possibility of continuing to investigate the behavior of high intensity in the decrease of IL-6.</p>

<p><strong>Introduction.</strong> Confinement was implemented as a preventive measure to limit contagion in the face of the COVID-19 pandemic. This measure limited food availability and favored the consumption of less healthy processed and non-perishable foods. These behaviors can be seen as related to mental health disorders, such as stress, anxiety, and depression. <strong>Methods.</strong> It is a quantitative, descriptive, cross-sectional study with non-probabilistic convenience sampling carried out between August-October 2020, with the participation of 1657 Latin American people from the general population. The Depression, Anxiety and Stress Scales-21 questionnaire and the eating behaviors questionnaire associated with stress, anxiety, and depression-17 were applied. Ordinal logistic regression was used to assess the association between variables. <strong>Results.</strong> The 62% of participants presented some degree of depression; 55.9%, anxiety; and 55.2%, stress. An association was found between stress with physical activity (p 0.048) and consumption of fish (p 0.041), water (p 0.003), breads / desserts (p 0.005), fast foods (p <0.001), sugary drinks (p 0.035), tea and infusions (p 0.023), and cocoa and its derivatives (p 0.018). Another association was also found between anxiety with physical activity (p 0.006) and intake of vegetables (p 0.022), fish (p 0.031), oils (p 0.008), breads / desserts (p 0.026), fast foods (p <0.001), tea and infusions (p 0.018), cocoa and derivatives (p 0.038), and vitamin supplements (p 0.016). Depression was also found as associated with physical activity (p 0.037) and consumption of fruits (p 0.012), water (p 0.012), coffee (p 0.045), breads / desserts (p 0.003), and fast foods (p <0.001). <strong>Conclusions.</strong> An association was found between consuming certain foods and high levels of stress, anxiety, and depression.</p>

<p>The study aims to conduct a bibliographic and structured review based on the results found around the influence of balance on the quality of life of people with Down Syndrome (DS) in school and adult ages. For references searching, the following keywords were used as descriptors: “<em>Down Syndrome</em>,” “<em>Balance</em>,” and “<em>Quality of life</em>.” The words were always introduced in English and computerized databases; SCOPUS, WOS, and SPORTDiscus were used. Four inclusion criteria were introduced to limit the search: i) <em>mentioning the influence of balance on the QOL of people with DS</em>, ii)<em> taking exclusively into consideration scientific articles, iii) having access to the full text or abstract</em>, and iv) <em>being written in English, Portuguese, or Spanish</em>. In conclusion, the documents about the influence of balance in people with Down Syndrome address different research topics. Of the thirty-four articles located in the first search, seven of them meet the inclusion criteria. The reviewed scientific literature shows that the practice of physical exercise and specific training produce improvements in balance and the quality of life of people with Down syndrome, which allows establishing the recommendation to specifically train balance during physical activity sessions since there is evidence of positive effects for this group.</p>

<p>We aimed to compare teams’ attack styles in Europe and South America elite football in the two most valued domestic leagues in both continents (Spanish <em>La Liga</em> & English <em>Premier League</em> in Europe, and Argentinian <em>Superliga</em> & Brazilian <em>Série A</em> in South America). For this purpose, we used a sample of 84 teams and 3,780 cases in 1,214 games. Using an observational tool, we analyzed performance indicators (goals, shots, dribbles, and passes) and attack situations. Effect size (<em>ES</em>) and non-clinical magnitude-based inference (<em>MBI</em>) were used to evaluate uncertainty. Results revealed that European teams scored more goals per game related to fast (<em>ES</em> = 0.35; likely <em>MBI</em>) and positional attack (<em>ES</em> = 0.36; likely <em>MBI</em>). In addition, teams from the European leagues spent more time playing in the opposition third zone of the pitch, performed a higher number of assists (<em>ES</em> = 0.38; likely <em>MBI</em>) and through-ball assists (<em>ES</em> = 0.46; likely <em>MBI</em>) than South American ones. Finally, South American teams made higher numbers of shots out of the box (<em>ES</em> = 1.52, almost certain <em>MBI</em>) and off-target shots (<em>ES</em> = 1.08; almost certain <em>MBI</em>), and they also spent more time playing in the middle third zone (<em>ES</em> = 1.65; almost certain <em>MBI</em>). No differences were identified in set-pieces goals, length passing, and aerial duels. These findings may provide information regarding attack style profiles from each continent league. Also, it could be highly beneficial for coaches to be able to continuously design the specific training situations of the offensive process.</p>

<p>The present cross-sectional (comparative) study aimed to compare the anthropometric and body composition parameters in professional soccer players over five seasons. It was conducted on 120 soccer players grouped in a cohort of 24 subjects per year. The age range was 18 to 37 years. The footballers were evaluated at the beginning of each season from 2012 to 2016; weight, height, six skin folds (triceps, subscapularis, supra-iliac, abdominal, thigh, and calf) were evaluated from 2012 to 2015. The Body Mass Index (BMI), fat percentage, fat mass, and FFM were calculated. The adipose tissue was grouped into three groups: arm (triceps + subscapular), trunk (supra iliac + abdominal), and legs (thigh + calf). Body weight, height, the sum of the 6 folds, and the MLG varied during the 5 years. For 2012 the results were the following: Weight, 76.6 ± 7.8kg; Height, 177.6 ± 5.7cm; Folds, 58.7 ± 12.8mm; MLG, 64.5 ± 6.3mm). In 2013, these were the results: Weight, 77.8 ± 6.4kg; Height, 178, 4 ± 4.4; Folds, 60.1 ± 15.9mm; MLG, 66.3 ± 3.5mm). These were the measures obtained in 2014: Weight, 74.9 ± 5.7kg; Height, 177.0 ± 5.8cm; Folds, 54.4 ± 14.7mm; MLG, 64.5 ± 4.5kg ). And these were of the year 2015: Weight, 74.1 ± 6.8kg; Height, 176.1 ± 5.5cm; Folds, 54.9 ± 15.6mm; MLG, 63.8 ± 4.6kg). Finally, in 2016 these were the measures collected: Weight, 72.7 ± kg; Height, 175.3 ± 6.9 kg; Folds, 50.8 ± 12.mm; MLG, 62.8 ± 5.9kg. This study verified that the soccer players' anthropometric profile and adipose tissue decreased each season, while the MLG reflected similar values in each of the evaluated cohorts.</p>

Bibliographic Review2023-09-11T15:46:11-06:00Olga Lucia Montoya HurtadoGladys Iliana SernaOswal Martínez Moreno
<p><strong>Introduction:</strong> At the neurophysiological level, the cerebellum, the basal ganglia, and the limbic system are important in the coordination and memory of movement. <strong>Objective:</strong> Understanding the processes involved in the sensoperceptive relationship of hearing and motor learning is a permanent motivation of different disciplines. <strong>Method:</strong> A documentary review is presented; it aims to analyze the relationship between auditory perception and motor learning using content analysis from the perspectives of audiology, medicine, and neurorehabilitation. The keywords and combinations taken into account were the following: hearing perception, learning, balance, coordination, and combinations hearing-learning, hearing-balance, and hearing-coordination. The databases and metasearchers Pubmed, Medscape, Trip, ScienceDirect, EBSCOhost, Pedro, Scielo, and Lilacs were used. Virtual libraries such as SINAB, Cochrane, University of Malaga, UsNational Library of Medicine, and National Institutes of Health were also consulted. We selected 22 articles that met the inclusion criteria. <strong>Results:</strong> A relationship was found between auditory perception and motor learning in the communication of auditory and motor sensory information at the level of processing in the cerebellum and basal ganglia, being a fundamental part of the retention and motor transfer. <strong>Conclusion:</strong> In the motor learning process involving the experience of movement, we propose the participation of hearing by integrating the perceived signals –visual, auditory, motor, and vestibular– that are concretized to improve learning, making it more effective, generating a more lasting memory.</p>

<p>This research performed data mining for men and women powerlifters for the categories of Equipped Powerlifting, Classic Powerlifting, Equipped Bench Press, and Classic Bench Press, recognized by the International Powerlifting Federation (IPF). It then conducted a nonlinear regression analysis based on age versus mean scores in terms of Wilks Points, IPF Points, and IPF GoodLift Points to obtain the fitted curve and the age of peak performance for each category. Overall, the performance for all categories of men and women in powerlifting and bench press starts with exponential growth from youth until close to the third decade, showing a peak performance between 27.67 to 31.50 years of age, and then a linear decrease during maturation and older age. Comparisons between men and women and between equipped and classic athletes do not show meaningful differences in age of peak performance, suggesting the same biological clock in terms of aging. The sport of powerlifting offers a useful model to study human beings' growth, maturation, and aging.</p>

<p><strong>Introduction</strong>: The specialized literature has described the benefits of strength training on running speed. In the same way, stimulation of training based on eccentric contractions has been shown to be effective in improving this quality. <strong>Objective</strong>: To determine the effects of a training protocol based on the stretch-shortening cycle (SSC) and another on eccentric contractions (Nordic curl) on the running speed in 20 meters in adolescents from the Ñuble Region, Chile. <strong>Methodology</strong>: 42 school subjects were divided into experimental group (n = 22) and control group (n = 20). The training was developed for 6 weeks, with a frequency of 2 sessions/week, going from a volume of 8 to 32 repetitions of Nordic curl per session for the experimental group. The speed performance was evaluated in 20 meters. With photocells, the T Student's was applied to compare the pre- and post-intervention results, and the effect size (ES) was calculated. <strong>Results</strong>: Statistically significant differences were found (p <0.05) from the intervention in the experimental group (pre= 3,43 s. vs post= 3,15 s.), and a large ES (1,04). <strong>Conclusion</strong>: It is concluded that the eccentric training based on the application of Nordic Curl improves the performance of the running speed.</p>

<p><strong>Background:</strong> Maximum oxygen consumption is an indicator of cardiorespiratory fitness. <strong>Aim:</strong> The purpose was, first, to relate and compare the V̇O<sub>2</sub>max as the dependent variable with the estimated distance in the six-minute walk test (SMWT) as the independent variable in university students and, secondly, to relate the distance (dependent) with demographic and anthropometric variables (independents). <strong>Methodology: </strong>A correlational, descriptive, and quantitative study with a non-experimental design was conducted on 110 university students. In the study, basic anthropometry and vital signs were measured. A direct method of V̇O<sub>2</sub>max (Bruce test) on a treadmill was applied. Then, the distance covered in the SMWT was evaluated with two equations available in the scientific literature. Differences between men and women were measured in the tests, the correlation between the distances estimated with V̇O<sub>2</sub>max and anthropometric variables, and repeated ANOVA measurement tests between V̇O<sub>2</sub>max and estimated distance were analyzed with the SPSS v.22 program (<em>p</em><0.05). <strong>Results:</strong> Significant correlations were found between V̇O<sub>2</sub>max and estimated distances (<em>p</em><0.05) in the total sample, men and women, and in some cases, the distance correlated with gender, age, weight, height, and BMI (<em>p</em><0.05). However, there were differences between V̇O<sub>2</sub>max and distances estimated in the SMWT (<em>p</em><0.001). <strong>Conclusions:</strong> The V̇O<sub>2</sub>max measurement method is different from the distance prediction equations, although they have a significant relationship.</p> <p><br><span id="transmark" style="display: none; width: 0px; height: 0px;"></span></p>

<p>The COVID-19 pandemic resulted in a worldwide sports shutdown, leading to a reduced athletes’ workload, which is likely to increase the risk of injury after return to play when coupled with the expected increase in competitive density after the confinement period. In this regard, the knee is one of the joints with the highest injury prevalence among female soccer players, being the injury of the anterior cruciate ligament (ACL) one of the most frequent and severe. Thus, the present study aimed to develop an ACL injury prevention program that female soccer players could carry out during confinement periods. After reviewing the scientific literature, it was observed that strength training (with a main focus on the posterior chain), improved landing technique, lumbopelvic stability, and flexibility are associated with a lower risk of ACL injury in women. The program focuses on modifiable risk factors, so it should serve as a guide that can be adapted according to each context: individual characteristics, initial conditions, and evolution of the subject during development. Therefore, this study presents an intervention aiming at reducing the probability of ACL injury in female soccer players, after confinement periods, by directly influencing mechanisms of ACL injury previously reported for female soccer players.</p>

<p><strong>Objective:</strong> This research aimed to examine the effect of the Active Mobile Schools intervention on self-efficacy, enjoyment, and the perception of the level of physical activity in Costa Rican and Panamanian children during the COVID-19 pandemic. <strong>Methodology:</strong> The research sample comprised 55 girls and boys, aged between 7 and 9 years, from two public schools in Panama and Costa Rica. <strong>Results: </strong>The study mainly found that the intervention positively affected (pre-post improvements) the three dependent variables, but only in self-efficacy was the effect statistically significant (with moderate magnitude). In enjoyment and level of physical activity, the effect was small. There were no differences between countries, but a trend of deterioration was found in the participants of the control groups, in the three variables, especially in the Panamanian participants. <strong>Conclusions</strong>: The study leads to the conclusion that this intervention showed that using a multilevel model in times of pandemic, it was possible to improve the perception of self-efficacy and maintain levels of enjoyment and physical activity in the participating population, unlike the control group that showed a deterioration of the three variables in the infants.</p>

A Case Study2023-09-11T15:46:10-06:00José M. GamonalesKiko LeónJesús Muñoz-Jiménez
<p>Social networks are useful and effective as a tool for improving sporting events. Therefore, the aim of the present study was to analyze the statistical data of participation and impact of social media (Facebook, Twitter, and Instagram) of the Gymnastics of Extremadura, and to know the influence of Covid-19 pandemic on them. For this, the participation and interaction data on social networks were analyzed, between the periods 2016-2017, 2017-2018, 2018-2019, and 2019-2020. The same marketing strategy was always used in all online media. A descriptive and exploratory analysis of the data was performed. The results showed that the number of participants in the event has increased significantly since the use of social networks, with women being the main followers. Facebook is the social medium mainly used by users to get to know the Gymnastics of Extremadura. Therefore, the results demonstrate the importance of knowing the interactions of followers on social media to plan new online marketing strategies. Also, despite the event being suspended, as a consequence of the Covid-19 pandemic, the statistical data of the event's social networks are increasing every year. Being, the moment of publication of the poster or suspension of the event, the instants that receive the greatest number of actions in social networks such as Like or Share / Retweet the news.<span id="transmark" style="display: none; width: 0px; height: 0px;"></span></p>

<p><strong>Introduction:</strong> The circus attracts the attention of professionals from different areas; among them are Physical Education teachers working in Elementary Education. In fact, several studies reveal that teachers can be the "key" to opening the door to circus activities in school. Therefore, we believe that analyzing their experience is an interesting way to understand this approach. This study aimed to investigate the introduction of the teaching of circus activities in two Brazilian schools in Elementary Education. <strong>Methodological procedures:</strong> This article presents a field study conducted in two Brazilian schools, one in the city of Itatiba-SP and another in Belo Horizonte-MG. Through observations and interviews, we tried to understand the context and characteristics of each proposal. <strong>Results and discussion:</strong> We found that, in both cases, the figure of the teacher is mainly responsible for the inclusion of the circus in school and that the activities developed are justified by contributing to a more expressive and artistic education. <strong>Considerations:</strong> The cases studied show us two interesting proposals to organize classes that can inspire other teachers, managers, or researchers.</p> <p><br><span id="transmark" style="display: none; width: 0px; height: 0px;"></span></p>

<p><strong>Objective:</strong> The aim was to compare the body composition using classical anthropometry and bioelectric impedance in university students of a Peruvian university. <strong>Method:</strong> a correlational, cross-sectional study with a research sample of 152 students (77 men and 75 women) enrolled in the 2018-II period with an average age of 20.45 ± 3.63 years. The body mass index and anthropometric measurements were calculated for the anthropometric method. The Yuhasz (1974) equation was used to determine the body fat percentage. The electrical bioimpedance method implemented the tetrapolar multi-frequency direct segmental measurement analyzer Inbody 120. Pearson coefficient was used to establish the correlation, and the Bland Altman graphical method and stability index were used for concordance. The data were analyzed using the statistical software application IBM SPSS Statistics, version 27.0. A level of significance (p <0.05) was used for all analyzes. <strong>Results:</strong> there is a strong statistically significant correlation (p<0.01 and r = 0.95) between the anthropometric and electrical bioimpedance methods to determine body fat percentage. In addition, there is a good agreement according to the Bland Altman graphical method, reinforced by the stability index to complement the interpretation (IE = 95%). <strong>Conclusions:</strong> Both methods are interchangeable with each other, so they can be used indistinctly in this type of population to determine body fat percentage.</p>
