This research aims to recognize the impact of unilateral and bilateral performance on the muscular – power improvement to the (Lower, uppers) limbs for soccer players.
The researcher used the experimental method with the “(before, after) measurment” designed for 2 experimental groups involved about 20 soccer players had performed the training programe in the preparation period where the 1st groupe (10 players) had performed the training program by using the unilateral performance and the 2nd group (10 players) had performed the Same programe at the same period by using the bilateral performance.
The major results were that every style (BL),(UL) heads to improve the muscular-power of the (low , upper) limbs , but the (UL) was more effective than the (BL) because the bilateral deficit reduced when we used the (UL) .
