The Effects of Primal Movement Exercise Program on Body Composition, Physical Fitness, and Isokinetic Trunk Strength in Male College Students

The purpose of this study was to analyze the effects of the Primal Movement exercise program on body composition, physical fitness, and isokinetic trunk strength in male college students. The subjects were 16 male college students, randomly assigned to an exercise group (n=8) and a control group (n=8). The Primal Movement exercise program was performed three times a week for 40 minutes over eight weeks, with progressively increasing exercise intensity. As a result, lean body mass significantly increased (p＜.05), while body fat percentage significantly decreased (p＜.05). Physical fitness showed significant improvements in grip strength (p＜.01), back strength (p＜.01), push-ups (p＜.05), the Sergeant jump (p＜.05), and one-legged standing with eyes closed (p＜.01). Isokinetic trunk strength significantly improved in all variables of absolute and relative muscle strength at 30°/sec and 120°/sec. The Primal Movement exercise program was confirmed to be an effective method for improving body composition, physical fitness, and isokinetic trunk strength in male college students. In particular, since this exercise program can be performed without equipment, it has great potential for use in home training and non-face-to-face environments. Future studies should expand the sample to include more diverse age groups and genders and examine its long-term effects.
