Resistance exercise overtraining and overreaching. Neuroendocrine responses

Area of Science:

• Exercise Physiology
• Sports Science
• Neuroendocrinology

Background:

• Overtraining syndrome (OTS) results from excessive exercise, leading to performance decrements.
• Recovery from OTS can take weeks or months, while overreaching is a milder form with rapid recovery.
• Most research on OTS focuses on aerobic exercise, with less understanding of resistance training impacts.

Purpose of the Study:

• To investigate the neuroendocrine responses to overtraining in resistance exercise.
• To compare these responses with those observed in aerobic exercise overtraining.
• To determine the applicability of current overtraining markers to resistance training scenarios.

Main Methods:

• Review of scientific literature on overtraining in aerobic and resistance exercise.
• Analysis of neuroendocrine system responses to varying resistance training stimuli (volume vs. intensity).
• Comparison of neuroendocrine profiles between aerobic and resistance exercise overtraining.

Main Results:

• High-volume resistance exercise overtraining elicits neuroendocrine responses similar to aerobic overtraining.
• Excessive resistance training intensity provokes a distinct neuroendocrine profile.
• Overtraining markers identified in aerobic exercise may not universally apply to resistance training.

Conclusions:

• Resistance exercise overtraining elicits unique neuroendocrine responses, particularly concerning training intensity.
• Current neuroendocrine markers for overtraining may require re-evaluation for resistance training contexts.
• Further research is needed to fully understand the neuroendocrine system's role in resistance exercise overtraining and performance decrements.
