Effects of resistance training intensity and volume on serum lipid profile and Apo A-I levels in male rats

Introduction and Physical activity and exercise have beneficial effects on lipoproteins levels. There is limited information available regarding volume and intensity effects ofresistance training on serum lipid-lipoproteins profile, especially apoA-I levels. The purpose of this study was to investigate the effects of resistance training intensity and volume on serum lipidprofile and apoA-I levels in rats. Thirty two male Wister rats (287 ± 24 g) were randomly divided into four groups: (1) control, (2) trained with low intensity, (3) trained with moderate intensity, and (4) trained with high volume in moderate intensity. The resistance training consisted of climbing a ladder carrying a load suspended from the tail. After 4 weeks resistance training body weight,serum lipid profile and apoA-I concentrations were measured. After 4 weeks resistance training we did not find any significant difference in serum lipid profile between groups. Serum apoA-I levels in group 4 significantly increased comparedwith control and training with low intensity groups. Discussion and This study indicated that resistance training with suitable volume and intensity in rats could increase serum apoA-I levels as well as prevention of weight gain, and alterations of serum apoA-I levels is affected by resistance training volume.
