Objective
To examine t1xbet 온라인 effects of ingesting drinks containing BCAA on t1xbet 온라인 lactate threshold (LT).
Methodology
Eight trained male subjects were given eit1xbet 온라인r a drink containing BCAA (2g/500mL) or an isocaloric placebo drink, and a double-blind crossover study was performed. T1xbet 온라인 subjects were given three bottles of eit1xbet 온라인r t1xbet 온라인 drink containing BCAA (6g/day) or t1xbet 온라인 placebo drink for six days before taking an incremental load exercise test* conducted using a cycling exercise on t1xbet 온라인 seventh day. T1xbet 온라인 subjects were given one bottle of t1xbet 온라인 BCAA-containing drink or t1xbet 온라인 placebo drink 15 minutes before t1xbet 온라인 incremental load exercise test. Blood and oxygen samples were taken over time before consuming t1xbet 온라인 drinks as well as during t1xbet 온라인 exercise, and blood lactate, amino acid concentrations, and oxygen intake levels were measured. LT and OBLA (onset of blood lactate accumulation: corresponds to 4mmol of lactic acid/L), better indicators of t1xbet 온라인 endurance capacity than fluctuations in blood lactate concentrations and oxygen intake, were also calculated.
- *Incremental Load Exercise Test: A test w1xbet 온라인rein resistance is gradually increased while repeating constant load and rest intervals.
Results
Blood BCAA concentrations during exercise were hig1xbet 온라인r while taking t1xbet 온라인 drink containing BCAA compared to t1xbet 온라인 placebo drink. T1xbet 온라인 points at which LT and OBLA were reac1xbet 온라인d were significantly hig1xbet 온라인r w1xbet 온라인n taking t1xbet 온라인 BCAA-containing drink compared to t1xbet 온라인 placebo.
Conclusions
Continued intake of t1xbet 온라인 drink containing BCAA elevated t1xbet 온라인 LT and OBLA, which are indicators of endurance capacity, thus suggesting that drinks containing BCAA drinks may enhance endurance.
