스프린트 인터벌 운동이 과체중과 정상체중 남성의 혈중 사이토카인, CRP 및 지질 농도에 미치는 영향

Abstract

This study was aimed to determine the effects of sprint interval training on blood cytokine, CRP, and lipid in over-weight and normal adult men. The subjects voluntarily participated in the experiment. And the subjects who have orthopedic disease or currently are on medication were excluded. 23 men were measured for body composition and classified into two groups that BMI: >25(kg/m2) or BMI: 18.5~ 24.9(kg/m2); over-weight group(n=10) and normal(n=13). Both groups participated in sprint interval exercise which was composed of six sessions, 30s all-out cycling and 4mins active rest, repeatedly. Blood samples were taken before and immediately after exercise, and IL-10, IL-6, CRP, LDL-C, and TC from those samples were analyzed. As a result, in the concentration of IL-6, there was a significant difference between groups, time, and interaction effect, respectively(p<.05). In the concentration of IL-10, there was a significant difference in time(p<.05). In the concentration of CRP, there was a significant difference between groups, time and interaction effect(p<.05). The concentrations of TC, LDL, and HDL were significantly different between time(p<.05). Based on this result, sprint interval exercise, which is known for having advantageous effects on the improvement of body composition and aerobic fitness, has a limitation that could stimulate an activation of cytokine and a production of CRP. Thus, special carefulness is required when over-weight person does sprint interval exercise.
