The Effect Of Walking Lunge With Unilateral Shoulder Press Exercise On Semi Smash Accuracy

Abstract

The semi-smash is a fast-paced attack technique in volleyball that demands the integration of explosive leg power, core stability, and shoulder control to produce an accurate and effective shot. However, extracurricular training at the school level often does not integrate functional strength training models specific to the biomechanical requirements of the smash. Plyometric training, specifically variations of the walking lunge with unilateral shoulder press, is a method capable of developing muscular power by simultaneously activating the lower and upper extremity kinetic chains, potentially improving smash accuracy. This study aimed to analyze the effect of this training on semi-smash accuracy in male extracurricular volleyball students at MTs Al-Khairat Tondo. The study used a quasi-experimental design with a non-randomized pretest-posttest control group. The sample consisted of 20 students selected using total sampling and divided into experimental and control groups (n=10 each). The intervention was implemented for 6 weeks, administered three times per week. Smash accuracy was measured before and after the intervention using a target smash test. The results showed a significant increase in both groups (p<0.05), but the highest increase occurred in the experimental group from 10.10 ± 1.79 to 14.10 ± 1.91 (p<0.001), compared to the control group from 10.20 ± 1.81 to 11.90 ± 1.91 (p=0.009). There was a significant difference between groups after the intervention (p=0.019) with a significant difference in improvement (p=0.002). It was concluded that walking lunge with unilateral shoulder press training had a significant effect on increasing the accuracy of students' semi smashes.
