The effect of unilateral and bilateral exercise on anaerobic power performance to football athlete/ Ady Nazmi Azhar

The purpose of the study was done to investigate whether the unilateral and bilateral exercise can affect the anaerobic power performance of football athletes. In this study, 30 subjects were chosen and divided into two groups which were unilateral and bilateral group respectively. The subjects underwent six-week unilateral training of single legged squat, unilateral hip extension and unilateral lunge. They also have done six-week bilateral training of bilateral back squat, bilateral front squat and bilateral hip extension. The athletes have done a pre-test one day before training and post-test after six week training. The data of minimum, mean and peak power have been recorded and calculated. The results shows that only peak power got significant result where pre peak power of athletes (784.47 ± 166.37) as opposed to the post peak power of athletes (839.47 ± 126.92) trained using unilateral exercises; there is statistically significant decrease of -63.6 (95% CI, -101.2 to 25.98), t(14) = -3.626, p < 0.05 while pre peak power of athletes (784.47± 166.37) as opposed to the post mean power of athletes (839.47± 126.92) trained using bilateral exercises; there is statistically significant decrease of -46.4 (95% CI, -83.52 to -9.28), t(14) = -2.681, p < 0.05. Thus, it can be concluded that unilateral and bilateral exercises can improve the peak power of the athletes.
