The effects of frequency and duration of exercise on the differentiation and miniaturization of adipocyte and the secretion of adiponectin

肥胖大鼠被随机分为2周（17 ~ 19周，每天）或4周（15 ~ 19周，约每两天）自愿运动组或对照组。与2周运动相比，4周运动促进了脂肪细胞的缩小，血液脂联素浓度值略有降低。提示低频长时间运动治疗比高频短时间运动治疗对脂肪细胞结构和维持血脂联素浓度更有效。

Obese rats were randomly assigned to either the 2 (17 to 19-week-old, everyday) or 4 (15 to 19-week-old, about every two day) weeks voluntary exercise or control group. Compared to 2 weeks exercise, 4 weeks exercise promoted the downsizing of adipocyte and provided the weak reduction in the value of the blood adiponectin concentration. These results suggested that the low frequency and long duration exercise therapy is more effective for the cellularity of adipocyte and maintenance of blood adiponectin concentration compared to the high frequency and short duration exercise therapy.
