Background: The explosive power shows itself in the great majority of movements and elements performed by the athletes, particularly in the jumps, which are essential corporal movements in several kinds of sport. The training directed to the development of jumping capacity presents a large number of exercises that aim to improve muscular power in the lower limbs and therefore the impulsion capacity. The vertical impulsion is an important measure used to calculate the explosive power of the lower limbs. This study aimed to analyzed the associations between age, gender, body mass index, and length of exercise on the limbs explosive power in taekwondo athletes.

Subjects and Method: A cross sectional study was conducted at Sangkuriang and Lions sports arenas in Cimahi, West Java, Indonesia. A sample of 95 Taekwondo athletes was selected for this study. The dependent variable was limbs explosive power. The independent variables were age, gender, body mass index, and length of exercise. Limb explosive power was measured by a number of vertical jump repetition. The other variables were collected by questionnaire. The data were analyzed by Chi square.

Results: The limbs explosive power increased with age (OR= 2.89; 95% CI= 1.23 to 5.77; p= 0.010) and length of exercise (OR= 7.44; 95% CI= 2.96 to 18.67; p<0.001). Gender increased the limbs explosive power, but it was statistically non-significant (OR= 1.14; 95% CI= 0.51 to 2.56; p= 0.900). The limbs explosive power decreased with body mass index, but it was statistically non-significant (OR= 0.72; 95% CI= 0.30 to 1.18; p= 0.600).

Conclusion: The limbs explosive power increases with age, length of exercise, and gender. The limbs explosive power decreases with body mass index.

Keywords: the limbs explosive power, length of exercise, body mass index
