What this trial studies

This study investigates how L-arginine supplementation affects the recovery of cardiorespiratory parameters following submaximal exercise tests. Conducted at the Stress Physiology Laboratory of UNESP, the study involves controlled environmental conditions and specific pre-test protocols to ensure accurate measurements. Participants will undergo two exercise phases, with one receiving L-arginine and the other a placebo, while various physiological parameters are monitored. The aim is to clarify the role of L-arginine in enhancing recovery post-exercise.

Who should consider this trial

Good fit: Ideal candidates are physically active males aged 18 to 30 with a BMI between 18.5 and 29.9.

Not a fit: Patients with cardiorespiratory, neurological, or other significant health issues, as well as sedentary individuals, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into nutritional strategies for improving recovery and performance in physically active individuals.

How similar studies have performed: While the specific effects of L-arginine on recovery are not widely studied, similar nutritional interventions have shown promise in enhancing athletic performance and recovery.
