The Effect Of Overhead Dumbbell Exercises On Improving Lob Shots In Badminton Games

Abstract

This study was motivated by the need to improve students’ badminton lob stroke performance through a simple, structured, and applicable training method in school-based physical education. The lob stroke is an important basic technique in badminton because it allows players to direct the shuttlecock high and deep into the opponent’s backcourt area. However, many students still experience difficulty producing a strong, controlled, and accurate lob due to limited arm strength, shoulder stability, wrist control, and overhead movement coordination. Therefore, this study aimed to determine the effect of overhead dumbbell training on improving badminton lob strokes among students of SMK Negeri 6 Makassar. This research used a quantitative experimental method with a control group pretest–posttest design. The sample consisted of 20 students, divided into two groups: 10 students in the overhead dumbbell training group and 10 students in the control group. The experimental group received overhead dumbbell training, while the control group followed regular badminton learning activities without the specific training intervention. Data were collected using a badminton lob stroke test before and after the treatment. The data were analyzed descriptively and inferentially using an independent sample t-test. The results showed that the experimental group improved from a pretest mean score of 15.4000 to a posttest mean score of 21.6000, with an increase of 6.2000 points. Meanwhile, the control group improved from 15.4000 to 18.5000, with an increase of 3.1000 points. The independent sample t-test showed a t-count value of 2.175, higher than the t-table value of 2.093, with a significance value of 0.043 < 0.05. It can be concluded that overhead dumbbell training has a significant effect on improving badminton lob stroke performance among students of SMK Negeri 6 Makassar.
