This retrospective study aimed to estimate the differences between selected indicators of physical fitness and body composition in young tennis players during COVID-19 pandemic (2020 2021) their values as predicted using pre-pandemic trend (2015–2019). Data were collected from boys (mean ± SD; 13.2 1.7 years) girls (13.1 1.9 annual tests. analyzed with linear mixed-effects models for males females, separately, predict test scores, adjusting age trends data. Compared expected values, fat mass increased (2020: 0.68; 0.44–0.92, 2021: 1.08; 0.72–1.43), whereas muscle decreased −0.22; −0.34–−0.10, −0.28; −0.46–−0.10) throughout pandemic. Interestingly, boys’ age-adjusted squat jump scores improved relative 0.19; 0.00–0.38, 0.35; 0.06–0.63). No other measured noted across observation period. The results this suggest that sustained reduction sports activity caused by may have negatively affected athletes; however, did not affect performance indicators.

ABSTRACT In 1985, Thomas and French published results of a meta‐analysis that examined sex differences in grip strength children 5 years age older. Their analysis included from only four studies, no update has been published. The purpose the current study was to use examine birth 16. 808 effects 169 studies conducted 45 countries between 1961 2023. total sample 353,676 (178,588 boys, 175,088 girls). From 16 age, consistently greater boys than girls. Between 3 10 old, effect size small‐to‐moderate, with female equaling 90% male (Hedges g = 0.33–0.46). At 11, decreased slightly, likely due girls reaching puberty before ( 0.29, 95% confidence intervals (CI) [0.22, 0.35]). 13, increased markedly 0.63, CIs [0.55, 0.70]). By 16, difference substantial, 65% 2.07, [1.86, 2.27]). Secondary analyses revealed is broadly similar mostly stable since 1960s, except for narrowing among 5–10‐year‐olds after 2010. Various biological factors explain why, on average, are stronger onward.

Twenty-metre shuttle run test (20mSRT), handgrip strength, standing broad jump, sit-and-reach, height, mass, (Kidscreen27 questionnaire) were measured 90 children (8–9 years) during October 2019 ("T0"), November 2020 ("T1"), 2021 ("T2") June 2022 ("T3"). Mixed-effects models showed age- sex-normalised BMI increased from T0 (mean: 0.71) to T1 (0.97), remaining elevated at T2 (0.95) T3 (0.89).

Even though these actions may have been necessary save lives, there some unintended consequences could affect future public health.The present study uses data from more than 24,500 Austrian elementary children (51.2% male) participated a state-wide fitness evaluation program, which was initiated 2016/17 year. In addition body weight height, on cardiorespiratory endurance, muscular power, speed, agility, flexibility object were collected three cohorts prior implementation restrictions (school years: 2016/17, 2017/18, 2018/19) one cohort 2022, after majority had lifted.Body mass index percentiles significantly higher post-COVID-19 (p < 0.01).

This study aimed to investigate the effects of a school-based exergame intervention on anthropometric parameters and physical fitness. Fifty-eight students (10.4 ± 0.8 years; 48% girls) were randomized into an (IG) control (CG) group. Both groups participated in regular education classes during three-month period. The IG additionally received 20-minute twice per week. At baseline following period, body mass index (BMI) waist-to-height ratio (WHtR) assessed. Furthermore, sprint test (ST), countermovement jump (CMJ), shuttle run (SRT) performed. Due prescribed quarantine measures, only 34 (18 IG; 16 CG) included final analysis. A significant group−time interaction was determined CMJ performance (p < 0.001; η2 = 0.403), with increase (+2.6 2.4 cm; p 0.315) decrease (−2.0 3.1 0.009; 0.190) CG.
