Abstract
Growth hormone, one of the anabolic hormones that plays an important role in the growth and development of various body systems at an early age. Physical activity, especially aerobic activity, plays an important role in the growth hormone secretion.
Aim: The aim of this study was to investigate the effects of continuous and intermittent exercise on growth hormone overweight girls 15-13 years old.
A total of 27 girls aged 13-15 years with BMI =27±1/8 were randomly divided into three groups (intermittent = 9, continuous = 9, control = 9). The intermittent and continuous groups each performed 8 weeks of training (24 sessions). The intermittent group (For 8 weeks, 24 sessions, with an intensity of 80-60% of maximum heart rate, 25-45 minutes of intermittent running with active rest per session) and the continuous group (For 8 weeks, 24 sessions, at 65% of maximal heart rate, running for 25-45 minutes per session) performed the exercise. The control group had no exercise program during this period. Blood samples of all subjects were taken 48 hours before and after the exercise protocol for fasting growth hormone evaluation.
The results showed that growth hormone was significantly increased in the training groups compared to the control group (P <0.05). There was also a significant increase in the intermittent training group compared to the continuous training group (P <0.05).
It seems that performing continuous and intermittent exercises may stimulate GH secretion. Intermittent exercise results in greater secretion of growth hormone in overweight girls aged 13-15 years. As a result, intermittent exercise can be recommended to overweight people for greater GH secretion.
