Abstract
Muscle explosive power is one of the physical components needed in various sports and is the greatest muscular power in the shortest period of time completing the task. Muscle explosive power always involves the strength and speed of explosive muscle contractions and involves spending the maximum muscle strength in a fast time. This study aimed to determine the effect of dynamic and static contraction exercises on increasing the muscle limb power by using quadriceps bench. This research was conducted at Department of Physiotherapy, Health Polytechnic of Ministry of Health in Makassar. The research type was quasi-experiment. The research sample was 30 people divided into two groups, the group was given dynamic contraction training and another group was given static contraction training to increase the explosive muscle strength of the limbs, so this research used pre-post test control groups design. Measurement of explosive muscle limb power was done by using vertical jump test. The result of paired t-test showed a significant difference (p <0.05) with the ability of vertical jump test before the training of dynamic contraction 40.20 ± 4.960 and after training 48.73 ± 5.378. Similarly, static contraction training showed significant differences (p <0.05) with the ability of vertical jump test before static contraction training 39.53 ± 4.438 and after training 46.87 ± 5.181. The independent t-test showed no significant difference (p> 0.05) between dynamic contraction training with static contraction training and vertical jump test. The conclusion of this study is that there is no difference in the effect of giving quadriceps bench dynamic and static technique on increasing the vertical jump test. However, judging from the average difference in value, the quadriceps bench granting of dynamic techniques is greater than the quadriceps bench of static techniques in increasing the vertical jump test of the legs.
