Efeito do treinamento de força e nutrição na concentração de hormônios anabólicos e catabólicos em atletas

Abstract

Strength training is widely used by athletes and exercisers as an effective strategy to enhance athletic performance and promote favorable physiological adaptations. In this context, hormonal regulation plays a crucial role, with anabolic and catabolic hormones playing a fundamental part in the body's response to training. Given this scenario, the general objective of this research is to investigate the relationship between strength training and variations in the concentration of anabolic and catabolic hormones in athletes. Thus, the following research question is posed: How does strength training influence the concentration of anabolic and catabolic hormones in athletes, and what factors may moderate this relationship? The methodology adopted for the study is a literature review, making it qualitative in terms of approach, and exploratory and descriptive in terms of type. The results indicate that the effects of strength training on the concentration of anabolic hormones, such as testosterone and growth hormone (GH), show acute and chronic increases in these substances following training sessions. These hormonal responses are associated with promoting protein synthesis and muscle growth. Furthermore, strength training can also modulate the concentration of catabolic hormones, such as cortisol, with acute reductions and chronic adaptations observed in response to appropriate training. Therefore, the effect of strength training on the concentration of anabolic and catabolic hormones in athletes reveals the complexity and importance of these hormonal modulations for physiological adaptations and athletic performance. In conclusion, strength training is capable of promoting favorable hormonal changes, including increases in anabolic hormones and reductions in catabolic hormones, thus providing an environment conducive to muscle hypertrophy and the development of athletic performance.
