초록
본 연구에서는 12주간 복합운동 후 체지방 감량 유･무에 따라 비만인의 건강체력, 혈중지질, 사회･심리적 변인이 어떻게 변화하는지를 알아보고자 하였다. 연구대상은 C시 소재 건강센터에서 실시한 복합운동에 참여한 회원 중 비만인 성인(체지방률 30% 이상) 26명이었다. 이들 중 체지방율 3% 이상 감량한 체지방 감량집단(14명)과 체지방 미감량집단(12명)으로 구분하여 건강체력, 혈중지질, 사회･심리적 변인 등을 분석한 후 다음과 같은 결과를 얻었다. 건강체력 변인 중 최대산소섭취량은 시점별로 사전에 비해 사후에 유의하게 감소하였으며 특히 체지방감량집단의 경우 긍정적인 변화가 뚜렷하게 나타났다. 유연성, 근력, 근지구력 등의 모든 생활체력 변인들 또한 사전에 비해 사후에 유의하게 증가하였다. 혈중지질 변인의 경우 TC와 LDL는 사전에 비해 사후에 유의하게 감소하였으며 사회･심리적 변인의 경우 식이효능감, 운동습관, 영양습관 등의 변인은 체지방 감량집단이 미감량집단보다 통계적으로 유의하게 개선된 것으로 나타났다. 이상의 결과를 종합하면, 12주간의 복합운동을 실시한 후 전체적으로 사전에 비해 사후에는 긍정적인 변화가 나타났으며, 식이 효능감, 운동습관, 영양습관 등은 체지방감량집단의 경우 체지방미감량집단에 비해 긍정적인 것으로 나타났다.
Abstract
The purpose of this study was to identify the effect of the same combined exercise on the physical fitness, blood lipid profile, and psychosocial variables of obese person according to body fat loss or no body fat loss for 12 weeks. The subjects of the study were 26 obese adults (body fat percentage 30% or higher) who participated in a complex exercise program at a health center in City C. Among these, the subjects were divided into a body fat reduction group (14 subjects) who lost more than 3% of their body fat and a non-body fat reduction group (12 subjects), and the following results were obtained after analyzing physical fitness, blood lipids, and psychological variables. Among the health physical fitness variables, maximal oxygen uptake significantly decreased after the test compared to before at each time point, and especially in the case of the body fat reduction group, positive changes were evident. All life physical fitness variables such as flexibility, muscle strength, and muscle endurance also significantly increased after the test compared to before. In terms of blood lipid variables, TC and LDL were significantly reduced after the treatment compared to before, and in terms of social and psychological variables, variables such as dietary efficacy, exercise habits, and nutritional habits showed statistically significant improvements in the body fat reduction group compared to the non-reduction group. After 12 weeks of combined exercise, overall, positive changes were observed after the exercise compared to before, and the dietary efficacy, exercise habits, and nutritional habits were found to be more positive in the body fat reduction group than in the non-body fat reduction group.
