The aim of the study was to evaluate jumping performance and lower limbs strength asymmetry in young soccer players by comparing this movement performed on both a conventional surface and a sand surface.\u0000Materials and methods. 20 young soccer players under 17 years old randomly performed a standing long jump, a single hop jump in the sagittal plane (Hop Jump Test) and a single side hop jump in the frontal plane (Side Hop Jump Test), first on a conventional surface (natural grass) and then on sand. The jump distance and strength asymmetry was calculated using the formula: (NDL / DL) x 100.\u0000Results. The values from the two different jumping conditions showed a statistically significant decrease in the Broad Jump Test (p<0.001, ES: 3.56), Hop Jump Test left limb (p<0.001, ES: 4.99), Hop Jump Test right limb (p<0.001, ES: 3.95), Side Hop Jump Test left limb (p<0.001, ES: 4.67) and Side Hop Jump Test right limb (p<0.001, ES: 2.98) in the sand condition.\u0000The asymmetry values in the Hop Jump Test and the Side Hop Jump Test showed a statistically significant increase (+21.5%, p<0.001, ES: 3.66 and +41.1%, p<0.001, ES: 1.99, respectively) when comparing the performance on grass and sand.\u0000Conclusions. This different performance response in the two different jumping modes leads to the hypothesis that young soccer players who want to stress their explosive strength ability and joint stability should favor the use of one-leg rather than two-leg jumps.\u0000The values described in the study lead to the hypothesis that training on sand should be suggested when the young soccer player presents modest values of inter-limb asymmetry measured on a conventional surface.","PeriodicalId":178000,"journal":{"name":"Physical Education Theory and Methodology","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117044024","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pace bowling is the most injury susceptible position in cricket due to repeated high intensity maneuvers. Previous studies on pace bowlers have considered anthropometric, biomechanical, and kinesiological factors for deciphering the injury etiology.\u0000Study purpose. The purpose of this study was to prospectively investigate the association of body composition parameters with the incidence of musculoskeletal injuries among pace bowlers in cricket.\u0000Materials and methods. A total of 44 healthy professional male pace bowlers (N=44; Age: 22.89±4.5 years; Height: 176±9 cm; Body weight: 76.34±8.09 kg; BMI: 21.4±3.1) were recruited from various cricket academies. They were assessed on anthropometrics, body composition, and aerobic fitness before the start of Indian cricket season (typically mid-September). Any non-contact sports injury accounting for significant time loss during the season was recorded followed by assessment of change in body composition status among injured and non-injured pace bowlers.\u0000Results. We found hamstring injury as the most prevalent injury (05/12). Lower back injury accounted for highest severity with time loss of 48 matches. Injured pace bowlers underwent higher training volume (hours/day; p=.009) prior to injury incidence, were significantly heavier, and had greater volume of total body water. All the pace bowlers gained significant amount of fat-free mass (FFM) from pre- to post-season.\u0000Conclusions. Higher training workload and higher body weight were associated with more injury risk among pace bowlers. Further research accommodating other predictive factors of body composition and psychomotor learning must be carried out to precisely predict injury risk among pace bowlers in cricket.","PeriodicalId":178000,"journal":{"name":"Physical Education Theory and Methodology","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115145587","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Online PFTs can assess students’ physical fitness, according to several studies. However, few papers examined this issue in the setting of a Philippine higher education institution.\u0000Study purpose. This experimental research examined how a subset of Physical Fitness Tests (PFTs) affects BMI improvement.\u0000Materials and methods. After five weeks of fitness tests, this study used an experimental design to compare pre- and post-test scores while controlling for gender, age, and BMI. A two-part survey questionnaire collected the participants’ data. First, gender, age, and pre-test BMI were provided. The Physical Activity Readiness Questionnaire was the second part (PAR-Q). Analysis of the 5-week experiment data used IBM SPSS version 27. Descriptive statistical approaches displayed the participants’ demographics and fitness testing results (frequency, percentage, mean, and standard deviation). Before and after the selected PFTs, the students’ performance was examined using the one-way ANOVA and the independent samples t-test to determine if factors like gender, age, and body mass index affected performance. After the fitness tests, the paired samples t-test was used to see if the pre- and post-test scores were statistically different.\u0000Results. Performance before and after the selected PFTs was not statistically different between age groups. Except for the vertical jump test, gender groups did not differ significantly. Males outperformed females. Finally, after five weeks of performing the recommended PFTs, post-test scores were statistically significantly higher than pre-test levels.\u0000Conclusions. The selected PFTs were useful in online learning, especially in a Philippine local institution. This study supports the idea that college physical education instructors can regularly test their students’ fitness levels using the above assessments.","PeriodicalId":178000,"journal":{"name":"Physical Education Theory and Methodology","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125609898","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research aims to evaluate and analyze the Final Time (FT), Split Time (ST), and Reaction Time (RT) records of 100-meter butterfly swimmers in four Olympic events in order to provide benchmarks and standards for the development of swimming training.\u0000Materials and methods. This research combines quantitative and qualitative approaches. This study utilized a sample of 32 athletes ranked first through eighth who competed in the 100-meter butterfly at four Olympics: the 2008 Beijing Olympics, 2012 London Olympics, 2016 Rio Olympics, and 2021 Tokyo Olympics. It utilizes secondary data in which all time results are obtained from the website (http://www.fina.org). The descriptive statistics of mean and standard deviation were utilized for statistical analysis in this study. The Kolmogorov-Smirnov test was used to determine data normality. For comparing data between Olympiads, a one-way multi-comparison ANOVA was used to verify interactions between RT, ST, and FT across Olympiads. To determine the effect of RT and ST on FT, one-way linear regression was used with a significance level of p<0.05 as a standard. SPSS Inc., Chicago, IL, USA, was utilized for all analyses.\u0000Results. ST and RT were found to influence the achievement of FT in the 100-meter butterfly stroke, and RT had an effect of 0,712 (51%), for both male and female swimmers, on the achievement of the time in the first 50 meters.\u0000Conclusions.
