Comparison of Somatotype, Physical Fitness and Blood Lipids between CrossFit Training and Weight Training

Abstract

The purpose of this study was to investigate the effects of crossfit and weight training program on somatotype, physical fitness, maximum strength and blood lipids in male college students. Twenty-six college students were assigned to either crossfit group(CFG: n=13) or weight training group(WTG: n=13). Crossfit program consisted of 1round with 6 items for 12 weeks(3days per week). Weight training program consisted of 3sets with 70% 1RM intensity for 12 weeks(3days per week). The results were as follows: First, somatotype showed positive effects in both groups, but there were no significant interaction effects. Secondly, physical fitness and maximum strength were improved on all items in both groups, but there were no significant interaction effects. Lastly, in the blood lipid factors, both groups was decreased in TG, LDL-C and was increased in HDL-C, but there were no significant interaction effects. Thus, crossfit program showed similar results in all measured variables despite shorter exercise time than weight training program. Further study on crossfit program consisting of various exercise intensity, time, form and muscle injury should be performed on various ages.
