The effect of obesity induction along with endurance training and diet change on weight changes and lipid profile of male Wistar rats

Physical inactivity and high-calorie diets have caused obesity and related metabolic diseases, therefore; The aim of this study was to investigate the effect of obesity induction along with endurance training and diet change on weight changes and lipid profiles of male Wistar rats.

The research method was laboratory type. The research subjects included 25 Wistar rats with an age range of 8 to 12 weeks, which were divided into 5 control and experimental groups by targeted selective sampling according to weight and age conditions. In the first stage, 4 days after the weaning period, the food program was started to fatten the rats. A 5-band treadmill was used for endurance training. The training program of the subjects was 30 minutes per day for 8 weeks at a speed of 8 meters per minute. Dependent t-test and one-way analysis of variance were used to analyze the data.

The results showed that there is no significant difference between the pre-test and post-test of the average weight of the obese group + standard diet + aerobics (p = 0.135) and the obese group + standard diet (p = 0.06). Also, there is no significant difference between HDL averages in any of the groups, but there is a significant difference between LDL averages in the control group and other groups (p<0.001).

It seems that endurance exercise has an effect on weight control when a low-fat diet is included.
