PENGARUH LATIHAN INTERVAL TERHADAP DAYA TAHAN PEMAIN SEPAK BOLA

Abstract

This study aims to determine the effect of interval training on improving the endurance of soccer players at Universitas Negeri Medan. The research method used an experimental approach with a pretest-posttest control group design. The research sample consisted of 60 soccer players divided into two groups: experimental group (30 players) and control group (30 players). The experimental group was given interval training for 8 weeks with gradually increased intensity, while the control group received conventional training. Endurance measurement was performed using the Cooper 12-minute running test. The results showed that interval training significantly improved the aerobic endurance of soccer players compared to conventional training (p < 0.05). The average increase in VO2max capacity in the experimental group reached 18.5%, while the control group only reached 7.2%. The conclusion of this study is that interval training is a very effective training method to improve the endurance of soccer players.
