Objective
To examine the effects 1xbet APK continued ingestion 1xbet APK drinks containing BCAA on exercise performance over consecutive days.
Methodology
12 male cyclists were given either a drink containing BCAA (4g/500mL) or an isocaloric placebo drink, and a double-blind crossover study performed. The subjects were given the drink containing BCAA every day for two weeks and performed a cycling exercise (at 75% V02 peak for 90 minutes, followed by a ride to exhaustion at 85% 1xbet APK VO2 peak intensity), as a test 1xbet APK exercise performance on the first day 1xbet APK the regimen as well as on the 15th and 16th days. Exercise duration was measured as an indicator 1xbet APK performance, vertical jump as an indicator 1xbet APK muscle fatigue, and CK (creatine kinase) activity as an indicator 1xbet APK muscle damage. The effects 1xbet APK a single intake 1xbet APK the BCAA-containing drink on the first day 1xbet APK the regimen, the effects 1xbet APK continued intake (for two weeks) on the 15th day, and the effects 1xbet APK exercising on consecutive days on the 16th day were assessed.
Results
The results 1xbet APK the exercise performance tests showed significant declines in exercise duration from consecutive bouts 1xbet APK exercise over two days when taking the placebo drink, whereas no such decline was observed while taking the drink containing BCAA. Regarding changes in vertical jump, an indicator 1xbet APK muscle fatigue, significant declines were found in the records when taking the placebo, while no such declines were observed while taking the BCAA-containing drink. Declines in the vertical jump records were suppressed significantly when taking the drink containing BCAA compared to the placebo drink. Furthermore, the decline in CK activity induced by consecutive bouts 1xbet APK exercise over two days was significantly inhibited when taking the drink containing BCAA compared to the placebo.
Conclusions
Exercise performance when exercising over consecutive days was maintained, and muscle fatigue and damage diminished due to continued ingestion 1xbet APK the drink containing BCAA. These results suggest that continuous ingestion 1xbet APK BCAA is effective for maintaining exercise performance and condition in competitive sports where daily training and games/matches are prolonged.
