Tivortin® aspartate, a solution of L-arginine aspartate, significantly reduced psychophysiological stress in athletes preparing for competition. This indicates improved mental readiness and stability for competitive loads.
Area of Science:
- Sports Medicine
- Exercise Physiology
- Psychophysiology
Background:
- Athletes face significant psychophysiological stress during competition preparation.
- Maintaining mental stability is crucial for optimal athletic performance.
Purpose of the Study:
- To evaluate the effectiveness of Tivortin® aspartate (L-arginine aspartate) on psychophysiological stress in athletes.
- To assess its impact on mental readiness for competitive loads.
Main Methods:
- A 14-day randomized, double-blind, placebo-controlled study.
- Participants received either Tivortin® aspartate (40 ml/day) or a placebo (3% glucose solution).
- Psychophysiological stress was assessed using a modified V.A. Ivanchenko questionnaire.
Main Results:
- The placebo group showed a significant increase in psychophysiological stress.
- Athletes taking Tivortin® aspartate exhibited a significant decrease in psychophysiological stress.
- This suggests improved psychological stability and mental resilience in the treatment group.
Conclusions:
- Tivortin® aspartate effectively reduces psychophysiological stress in athletes.
- L-arginine aspartate supplementation can enhance mental readiness for competition.
- This supports the use of L-arginine-based substances to improve psychophysiological characteristics during exertion.
