In an attempt to address the issues surrounding much of the research, several researchers have proposed that the assessment of upper body power using medicine ball throws may provide a more functional

, there is a scarcity of studies that have examined the effects of caffeine ingestion while using both upper- and lower-body exercise tests in the same group of participants. In our recent study, 3 we reported that caffeine ingestion in the dose of 6 mg·kg −1 enhances the medicine ball throw distance (a

Prior to testing, all players performed a dynamic warm-up and stretching regime consisting of three repetitions of each test. The load imposed by the battery of tests

During each session, players were divided into 2 groups, with group 1 performing the sprint tests and countermovement jump first and group 2 completing the change of direction test and medicine ball throw. The groups then swapped and came

Physical fitness is strongly associated with several positive health indicators among adolescents. However, its association with body mass index status is inconsistent. The aim of this study was to explore the association between overweight/obesity and physical fitness among children and adolescents.
The design consisted of a cross-sectional study comprising 519 Brazilian students age 7 to 15 years. BMI status was assessed according to sex- and age-specific growth charts. Physical fitness was assessed using 8 tests: sit-and-reach, stationary long jump, 1-minute curl-up, modified pull-up, medicine-ball throw, 9-minute run, 20-m run, and 4-m shuttle-run.
Prevalence of overweight and obesity was 24% and 12%, respectively. Boys performed better than girls in all tests, except flexibility. Normal weight students performed better than overweight and obese students in all tests, except the sit-and-reach and the medicine-ball throw. Cardiorespiratory fitness had the strongest association with BMI status. The prevalence of obese subjects classified as “most fit” was less than 10%.
Higher values of body mass index were associated with declines in physical fitness, independent of age. The majority of obese children and adolescents and almost a half of those overweight were classified in the third tertile of physical fitness (least fit).

The Eurofit Special Test is a battery of motor fitness tests resulting from a 10-year project of the Committee of Experts for Sports Research and is comprised of strength, speed, flexibility, and balance. The purpose of this study was to investigate whether the Eurofit Special was able to distinguish variations in functioning among individuals with intellectual disabilities. Significant differences were found in long jump flexibility 25-m dash, medicine ball throw, balance walk, sit ups in 30-s. Analyses demonstrated that the Eurofit Special was able to discriminate performance levels by gender, age, and level of intellectual disability (mild: 177 female, 368 male; moderate: 359 female, 476 male; severe: 92 female, 111 male).

The aim of this study was to analyze the effects of an 8-week (conducted biweekly for a total of 16 sessions) plyometric training program (PT) (e.g., upper- and lower-body exercises) combined with regular tennis training on physical qualities in young tennis players.
Sixty tennis players between the ages of 12 and 13 years (age 12.5 ± 0.3 years, weight 44.2 ± 7.0 kg, height 156.6 ± 7.1 cm) were allocated to either the control group (standard in-season regimen) (CG; n = 30) or the experimental group, which received an additional PT (TG; n = 30) for 30–60 min as a substitute for some tennis training within the usual 90-min practice.
Pre- and posttests included: anthropometric measures; vertical countermovement jump (CMJ); standing long jump (SLJ); 20 m sprint time (with 5 and 10 m splits); a modified 505 agility test; overhead medicine ball throw; and serve velocity test.
After the training intervention, the TG showed significant (p < .01) improvements in all the parameters analyzed, with percentages of change and effect sizes ranging from 3.1% to 10.1% and 0.4 (small) to 1.3 (moderate), respectively. No significant changes were observed in the CG after the training intervention.
PT was shown as an important stimulus for enhancing explosive actions in young tennis players.
