COMPARISON OF ARM AND LEG MUSCLE FATIGUE DURING A 3X3 BASKETBALL GAME: A PRE- EXPERIMENTAL STUDY

This study aims to analyze the differences in fatigue that occur in the explosive power of the arm and leg muscles after a 3x3 basketball game. Muscle fatigue is an important factor that affects player performance, especially in sports that rely on explosive muscle strength, such as basketball. This study uses a pre-experimental design with a quantitative approach, involving 12 participants as the sample. The data obtained from the measurement of arm and leg muscle explosive power were analyzed using the Shapiro-Wilk test to examine data distribution normality, Levene's test for homogeneity, and paired sample t-tests to identify significant differences between pre-test and post-test data. The results show a significant decrease in arm and leg muscle explosive power after the game, with significance values of 0.047 (t = -2.235) for arm muscles and 0.046 (t = -2.247) for legmuscles. This decrease indicates that muscle fatigue from the 3x3 game significantly affects player performance. This study highlights the importance of managing muscle fatigue to improve basketball player performance, especially in competitions that rely on explosive muscle strength.
