The purpose of our study was to assess the test-retest reliability and concurrent validity of the 30 sec Sit to Stand test in a sample of adolescents. We recruited 30 male (58%) and 22 female (42%) participants (mean age = 15.77 years ± 0.46). Participants completed the 30-sec Sit to Stand and standing long jump tests on two occasions separated by…

This study investigates the predictive validity of lower extremity strength, strength asymmetry, and soccer-specific fitness in talent identification among elite male youth soccer players. Employing a Retrospective Cohort design, we established a cohort consisting of K-League registered youth players, totaling 219 individuals (all males, aged 16…

Using a sample of healthy youth (n = 466, 10 to 18 yr), we report the predictive utility of vertical jump power (VJ Power, W) for predicting bone strength. We measured VJ Power using mechanography and an indicator of bone strength, i.e., height-adjusted total bone mineral content less head (TBLH BMC, g), using DXA. Growth curve models were used to…

The main purpose of this study was to examine the relationship between cardiovascular endurance and mental toughness among football players of Academy Mokhtar Dahari (AMD). Twenty players were selected as respondents. Data were collected using Yo-Yo test level 1 and Mental Emotional Bodily Toughness (MeBTough) Questionnaires (Mark, 2008). This…

A central goal of physical education (PE) is to empower students to be physically active in a health-enhancing way. Therefore, using a competence-based approach, the objective of the health- and fitness-related PE intervention 'Promotion of physical activity-related health competence in PE' (GEKOS) was to address practical and theoretical content…

We developed plank test standards, based on trunk lean mass-to-fat mass (LM/FM) ratio, in a sample of healthy Portuguese 10--18 year olds (n = 474, 46.4% female). Height and weight were measured and muscular endurance was assessed using the prone plank test. Trunk LM/FM ratio was determined using dual-energy x-ray absorptiometry. Plank standards…

Introduction: The aims of this study were to examine cross-sectional, and longitudinal association of different measures of obesity and physical fitness with cardiovascular disease (CVD) risk factors in adolescents with Down syndrome. Methods: Longitudinal analysis included 90 adolescents with Down syndrome. Obesity and physical fitness were…

We developed age- and sex-specific smoothed percentiles for vertical and long jump, as well as vertical jump power, in healthy 10-18 year olds (n = 529, 47.1% female). Jump height and distance were measured and vertical jump power was assessed via mechanography. LMS regression was used to create smoothed age-specific reference curves, separated by…

Purpose: The purpose of this study was to investigate the impact on health-related fitness resulting from COVID-19 lockdowns on male high school students in Melbourne, Australia. Method: A total of 146 students completed fitness testing in February and retesting in November following 7 months of remote learning. Fitness tests conducted were 20-m…

The aim of this study is to determine the physical fitness levels of individuals with autism by comparing them with individuals in the early and middle adolescence periods with normal development and the needs of the individuals with autism in terms of physical fitness. This study is carried out at the Selçuklu Autism Foundation, which is the…

With this study we aimed to investigate the impact of a 12-week manipulative skills exercise programme on the motor proficiency of young individuals with intellectual disabilities. A total of 32 learners diagnosed with mild intellectual disabilities, with an average age of 17.81 ± 1.44 years, were divided into 2 equal-sized groups: a control group…

Incorporation of the vertical jump (VJ) test in health-related fitness batteries is predicated on the availability of prediction equations to accurately estimate VJ power. The purpose was to develop and validate a generalizable equation to estimate VJ power from VJ height, body mass, age, and sex in 10- to 18-year-olds. The sample (N = 529)…

The aim of this research is to reveal the boxers' views in order to determine the theoretical and methodological aspects of the development of the sense of distance in the technical training of the first proficiency boxers. This research was conducted with the phenomenology pattern, one of the qualitative research designs. Study data were…

It is aimed in this study to analyze the effects of the Montessori education method on children with Down syndrome and autism having special training who have received and not received Montessori education through the Eurofit test batteries selected for motor skills and physical fitness. A total of 20 male children with Down syndrome and autism in…

The purpose of this study was twofold: (1) to examine the effect of an adapted physical education (APE) program on physical fitness of adolescents with intellectual disabilities, and (2) to investigate the associations between the changes of physical fitness tests over the course of a three-year period. A secondary data analysis design was used to…
