Abstract
Introduction: In badminton, anthropometric characteristics and physical
capacities are essential to meet playing demands across ages and sexes. The
objective of this study was to investigate age- and sex-related differences in
anthropometric characteristics and physical capacities among highly trained
junior badminton players, focusing on differences between (i) under (U) 13,
U15, and U17 age groups, and (ii) sexes within each age group.
Materials and methods: Sixty-two Indonesian highly trained junior badminton
players were tested over two sessions for body height, weight, fat mass, and
body mass index (BMI), as well as balance, reaction time, hand grip strength,
counter movement jump (CMJ) height, linear and non-linear sprint times, and
anaerobic sprint and multistage fitness test performances. Traditional (oneway
ANOVA or Kruskal–Wallis tests) and alternative statistical approaches
(magnitude-based inferences) as well as effect size (ES) calculations were
applied for statistical analysis.
Results: Regarding age-related differences, in males, U17 players had a
statistically significant and most likely higher BMI ( p = 0.001; ES = very large),
as well as statistically significant and most likely superior CMJ height, linear
sprint performance, fatigue index, and relative peak power than the U13
players ( p ≤ 0.003; ES = large to very large). In females, U17 players had a
statistically significant and most likely higher BMI and body fat mass
( p ≤ 0.002; ES = large to very large), as well as statistically significant and very
likely inferior non-linear sprint performance and relative peak power than the
U13 players ( p ≤ 0.005; ES = large). For sex-related differences, in U17 and
U15 players, males had a statistically significant and most likely lower body fat
mass ( p = 0.001; ES = very large), as well as statistically significant and most
likely superior linear sprint performance and relative peak power than females
( p = 0.001; ES = large to extremely large).
Conclusion: This study shows that anthropometric characteristics and
anaerobic capacities differ by age and sex, whereas aerobic capacity is similar
among Indonesian highly trained junior badminton players. These findings
can support training, testing, and talent identification to help develop highly
trained juniors into world-class badminton players.
