Analysis of the Relationship Between Arm Muscle Mass and Hand Grip Strength on Basketball Players' Shooting Performance

Abstract

This study aims to analyze the relationship between arm muscle mass and handgrip strength on basketball players' shooting performance. A sample of 21 basketball players from the Surabaya State University student league used long-range shooting or three-pointers as a research indicator. The study used a quantitative cross-sectional design. Arm muscle mass was measured using BIA, handgrip strength using a handheld dynamometer, and shooting performance through a 10-shot three-pointer test. Shapiro–Wilk analysis showed a normal distribution of the data, so the Pearson correlation test was then used. The results showed a positive and significant relationship between arm muscle mass and three-pointer shooting percentage (strong relationship) and between handgrip strength and three-pointer shooting percentage (moderate relationship). These findings indicate that upper extremity strength plays an important role in the stability and control of long-range shooting or shooting performance, but still depends on the player's technique and neuromuscular control.
