| Description | The purpose of this study was to model isokinetic strength in adolescent recreational karate athletes. Subjects (7 males, 17.21±2.63 years, 1.67±0.05 m, 57.68±10.19 kg and 5 females, 18.50±1.28 years, 1.64±0.04 m, 58.22±6.43 kg) were recruited from a local karate club. Gravity-corrected strength was assessed on a Biodex 3 isokinetic machine at 120o /s and 300o /s during extension and flexion of the dominant kicking leg. Collapsed over gender, absolute peak torque during extension at 120o /s (148.12±35.63 Nm) was higher than during flexion at 120o /s (66.15±18.49 Nm) (d=3.03, 95% CI: -17.13– 13.49). Flexion at 120o /s (23.91±6.07 Nm3.069) was lower than extension at 300o /s (36.96±7.58 Nm3.069) (d=1.65, 95% CI: -5.60–5.94). It is suggested that geometric similarity may not apply to isokinetic strength in adolescent karate athletes.
