Analisa Daya Tahan Kardiovaskuler Atlet Lari Jarak Jauh dengan Pendekatan Latihan Overhead Extension dan Continuous Run

This study aimed to measure the comparative effectiveness of continuous running and overhead extensions in improving cardiovascular endurance in long-distance runners at the JAS Athletic Club. Using a two-group pretest-posttest experimental design with a sample of 20 athletes, the study found that both exercises increased cardiovascular endurance (VO₂max). However, the effect of continuous running was significantly greater. These findings indicate that continuous running is superior for aerobic endurance, while overhead extensions are more suitable as a supplementary exercise for muscle strength.
