PHYSICAL FITNESS OF RECREATIONAL ADOLESCENT TAEKWONDO ATHLETES

Abstract

"NOORUL, H. R. ; PIETER, W.; ERIE, Z. Z. Physical Fitness of Recreational Adolescent Taekwondo Athletes. Brazilian Journal of Biomotricity, v. 2, n. 4, p. 230-240, 2008. The purpose of this study was to describe the physical fitness of adolescent recreational taekwondo athletes. Subjects were members of the Kelantan State taekwondo team from Malaysia (8 males, 18.63 ± 1.92 years, 168.65 ± 7.36 cm, 68.29 ± 20.69 kg, and 9 females, 18.10 ± 1.37 years, 158.22 ± 4.11 cm, 59.72 ± 10.03 kg). Flexibility, explosive leg power, muscular strength and endurance, aerobic fitness and maximum exercise heart rate (HRex) were assessed. In absolute terms, the boys (52.07 ± 11.07cm) jumped higher than the girls (34.04 ± 5.21 cm, p = 0.001, eta2 = 0.476). The difference became smaller when jump height was scaled to height (m2) (17.39 ± 3.07 cm/m2 and 14.25 ± 1.66 cm/m2 for the boys and girls, respectively, p = 0.020, eta2 = 0.331). There was no difference between boys (25.00 ± IR15) and girls (31.50 ± IR 17) in push-ups, although the females recorded a higher median score (p = 0.335, ES = 0.406). There also was no difference between gender (39.00 ± IR7 vs. 39.50 ± IR11) in sit-ups (p > 0.05, ES = 0.054). The boys had greater aerobic endurance but the effect was small (42.18 ± 7.86 ml.kg-1.min-1 vs. 30.71 ±5.46 ml.kg-1.min-1, p = 0.003, eta2 = 0.453). The difference persisted when height was used as a co-variate (43.32 ± 8.44 ml.kg-1.min-1 for the boys and 29.70 ± 8.283 ml.kg-1.min-1 for the girls, p = 0.012, eta2 = 0.375). In conclusion, sexual dimorphism in physical fitness was ound in recreationally active adolescent athletes."
