Abstract

Background: The aim of this study was to Investigating the role of resistance training intensity on hormonal changes involved in hypertrophy and performance of bodybuilding athletes.

Methods: For this purpose, 30 professional athletes were randomly divided into three groups of intense periodic resistance training, traditional resistance training and controls were divided. After initial sampling, the intervention groups were active for 12 weeks. Blood samples were taken 48 hours after the last training session to remove the response to the last training session. All data were analyzed at the significant level P≤0.05.

Results: The results showed that testosterone, weight, fat percentage and body mass index in the periodic resistance training group had a significant change compared to the control group and traditional resistance training (P<0.05). The results also showed that the strength of the upper body and lower torso in the intervening groups increased significantly compared to the control group (P<0.05). Low trunk strength is also a significant difference between the intervention groups and the control group. But there is no significant difference between the traditional and intermittent resistance training group (P>0.05). However, these incremental changes have been more pronounced in the periodic resistance group. However, no significant change was observed in insulin, insulin resistance, glucose and glucagon (P>0.05).

Discussion and Conclusion: The intensity of training seems to be an important and influential factor in the rate of change in factors related to athletes' performance. But it did not change the hormonal status of the athletes. Of course, more research is needed in the future to reach a definitive conclusion.
