Objective
To assess the effects of branched-chain amino acid (BCAA) supplementation on muscle soreness, 1xbet 보너스 코드.
Methodology
12 long-distance track 1xbet 보너스 코드 field athletes (male 1xbet 보너스 코드 female) were given either a drink containing BCAA (4g/500mL) or an isocaloric placebo drink, 1xbet 보너스 코드 a double-blind crossover study performed. A three-day high-intensity training program was conducted twice, with a three-week interval between the programs. Every day during the training period, subjects ingested 2,500mL of either the BCAA drink or the placebo drink, 1xbet 보너스 코드 overall muscle soreness 1xbet 보너스 코드 fatigue were determined using the VAS method*. Blood samples were taken before the training 1xbet 보너스 코드 after the three-day trainings, 1xbet 보너스 코드 blood creatine kinase (CK) 1xbet 보너스 코드 lactate dehydrogenase (LDH), indicators of muscle damage, as well as plasma granulocyte elastase, an indicator of inflammation, were measured.
- *VAS Method: An abbreviation for the "Visual Analog Scale" method. A 10cm horizontal line connects opposing points on either end of the line, 1xbet 보너스 코드 respondents mark a single vertical line corresponding to their mood (feelings) at the time, thus providing a way of quantifying subjective feelings by measuring the distance of the vertical line from the left edge.
Results
Compared to pre-training levels, increased muscle soreness was observed post training both when taking the placebo drink 1xbet 보너스 코드 when taking the BCAA drink. However, the onset of soreness was inhibited significantly more when taking the drink containing BCAA compared to the placebo. Fatigue was also inhibited significantly more when taking the BCAA drink relative to the placebo. Blood CK 1xbet 보너스 코드 LDH activity were significantly suppressed when taking the BCAA drink compared to when taking the placebo drink. Post-training plasma granulocyte elastase was significantly high only when taking the placebo drink. Significantly lower plasma granulocyte elastase was found when taking the BCAA drink relative to the placebo.
Conclusions
Intake of drinks containing BCAA alleviates muscle soreness and fatigue during high-intensity training programs while simultaneously diminishing 1xbet 보너스 코드. The results suggest that drinks containing BCAA may be effective in regulating the physical condition of athletes during successive bouts of high-intensity exercise, such as at training camps.
