ABSTRACT

Kang, H.S. Effect of voluntary resistance exercise on body composition, bone calcium concentration in glucocorticoid -injected rats. Exercise Science, 12(2): 307-318, 2003. The purpose of the study is to investigates effect of voluntary resistance exercise on body composition, bone calcium concentration in glucocorticoid -injected rats. To determine the effects of tower climbing exercise on hematological status in glucocorticoid injected rats as an aging model, 29 male Sprague-Dawley rats, 10 weeks of age, were assigned to three groups : a saline control group(SS, n=9), a glucocorticoid -sedentary group(GS, n=10) and a glucocorticoid-exercise group(GE, n=10). The GS and GE groups were given 2 mg/kg/day of prednisolone. The GE group voluntarily climbed the 200-cm tower to drink water from the bottle set at the top of it. Weight gain during the 8-week experimental period was greater in the SS group than in the GS and GE groups. And bone calcium concentration was greater in the GS and GE groups than in the SS group. The hematological parameters were not influenced by glucocorticoid administration with or without climbing exercise. 자발적인 저항성운동이 글루코코르티코이드를 투여한 쥐의 체조성 및 골 칼슘 농도에 미치는 영향강 형 숙스포츠의학영양연구소
