The effect of linear loading circuit training on physical fitness

BACKGROUND: Physical fitness is one of the important factors in basketball games. The purpose of this study was to examine the effect of linear loading circuit training towards physical fitness components which are cardio respiration endurance, anaerobic skill, agility, and the muscle power. METHODS: This research used experimental method in which one group pre-test-posttest design was applied. The subject of high school students with its basketball extracurricular male students (age 16 until 18 years old). The sample amount of 30 students was taken randomly. Cardio respiration endurance instrument used Multi Stage Fitness Test, the anaerob skill used 20 meters sprint test, the agility used Illinoise test, and the legs muscle power used vertical jump test. The data analysis used statistical paired samples t-test. RESULTS: The research result shows P<0.05 at cardiorespiration endurance, anaerobic skill, agility, and the muscle power. CONCLUSIONS: Hence, it can be concluded that there is a positive effect of the circuit training with the enhancement of linear loading towards cardio respiration endurance, anaerobic skill, agility, and the muscle power. This training program can be used to increase basketball extracurricular male students' physical fitness.
