Effect of Eight Weeks of Combined aerobic-resistance Training on Sleep Quality, Prolactin Hormone, and Growth Hormone, of Overweight and obese adolescent girls

The purpose of this study was to determine the effect of eight weeks of combined training (aerobic-resistance) on sleep quality, prolactin hormone and growth hormone, of overweight and obese adolescent girls.

The current research was of a semi-experimental type. In this study, 30 overweight and obese adolescent girls were randomly divided into two experimental groups of 15 people (average age: 16.33 ± 0.97 years; body mass index: 26 30.48±3 kg/m2) and the control group (mean age: 16.53±1.18 years; body mass index: 30.48±3.26 kg/m2) were divided. Eight weeks experimental group they performed progressive aerobic-resistance exercises three sessions a week. Each session consists of 10 minutes of warming up, 5 minutes of cooling down, 30 minutes of aerobic exercise with an intensity of 60-80% of the maximum heart rate and 45 minutes of resistance exercise with an intensity of 50-70%. Repetition was the maximum. Before and after eight weeks of training, sleep quality, anxiety level and prolactin and growth hormones were measured. Statistical information was obtained by one-way ANCOVA and Yeoman-Whitney tests through spss software. 22 cases were analyzed. A significance level of p0.05).

A combined training course (aerobic-resistance) probably improves the quality of sleep of overweight and obese students and has no effect on prolactin and growth hormone levels
