The Effect of Skipping Exercise on Increasing VO₂Max in Extracurricular Basketball Participants at Pirngadi Christian High School, Surabaya

Abstract

Background: Cardiorespiratory endurance is an important component in basketball performance that requires repeated intensive physical activity. VO₂Max describes the body's maximum ability to absorb and utilize oxygen during aerobic activity. One simple and effective exercise to increase VO₂Max is skipping (jumping rope). Objective: To analyze the effect of skipping exercise on increasing VO₂Max in basketball extracurricular participants at Pirngadi Christian High School, Surabaya. Method: The study used a quasi-experimental design with a one-group pre-test and post-test design. A total of 20 students participating in the basketball extracurricular were selected using a purposive sampling technique. The skipping exercise intervention was carried out for 6 weeks, 3 times per week. VO₂Max was measured using a bleep test. Data analysis used a paired sample t-test with a significance level of 0.05. Results: The results of the normality test showed that the data were normally distributed. The paired t-test results showed p = 0.000 (p < 0.05), indicating a significant difference between VO₂Max before and after skipping training. Conclusion: Skipping training significantly increased VO₂Max in extracurricular basketball participants at Pirngadi Christian High School, Surabaya.
