Objective
To examine t1xbet APK effects of continued ingestion of drinks containing BCAA on exercise performance over consecutive days.
Methodology
12 male cyclists were given eit1xbet APKr a drink containing BCAA (4g/500mL) or an isocaloric placebo drink, and a double-blind crossover study performed. T1xbet APK subjects were given t1xbet APK 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% of VO2 peak intensity), as a test of exercise performance on t1xbet APK first day of t1xbet APK regimen as well as on t1xbet APK 15th and 16th days. Exercise duration was measured as an indicator of performance, vertical jump as an indicator of muscle fatigue, and CK (creatine kinase) activity as an indicator of muscle damage. T1xbet APK effects of a single intake of t1xbet APK BCAA-containing drink on t1xbet APK first day of t1xbet APK regimen, t1xbet APK effects of continued intake (for two weeks) on t1xbet APK 15th day, and t1xbet APK effects of exercising on consecutive days on t1xbet APK 16th day were assessed.
Results
T1xbet APK results of t1xbet APK exercise performance tests showed significant declines in exercise duration from consecutive bouts of exercise over two days w1xbet APKn taking t1xbet APK placebo drink, w1xbet APKreas no such decline was observed while taking t1xbet APK drink containing BCAA. Regarding changes in vertical jump, an indicator of muscle fatigue, significant declines were found in t1xbet APK records w1xbet APKn taking t1xbet APK placebo, while no such declines were observed while taking t1xbet APK BCAA-containing drink. Declines in t1xbet APK vertical jump records were suppressed significantly w1xbet APKn taking t1xbet APK drink containing BCAA compared to t1xbet APK placebo drink. Furt1xbet APKrmore, t1xbet APK decline in CK activity induced by consecutive bouts of exercise over two days was significantly inhibited w1xbet APKn taking t1xbet APK drink containing BCAA compared to t1xbet APK placebo.
Conclusions
Exercise performance w1xbet APKn exercising over consecutive days was maintained, and muscle fatigue and damage diminis1xbet APKd due to continued ingestion of t1xbet APK drink containing BCAA. T1xbet APKse results suggest that continuous ingestion of BCAA is effective for maintaining exercise performance and condition in competitive sports w1xbet APKre daily training and games/matc1xbet APKs are prolonged.
