The purpose of this study was to determine the effects of beta-alanine supplementation and altitude training on aerobic capacity(200m swim performance) and muscle power in K university’s swimmers. Fourteen male swimmers(two groups; β-ala & Con) were performed swim trials in sea level and altitude(1980m) for respectively 4wk(total 8wk). We were checked 200m X 5th records and muscle power(60o/sec Peak torque) analysis at 3 times(pre, 4wk & 8wk). Body compositions(weight, %BMI, muscle mass) were measured pre & post(8wk). The results showed that 200m swim performance records was significantly different pre training between sea level training (p<.05) and pre training between altitude training (p<.001) in β-ala group. But not Con group(placebo). Muscle power(60o/sec Flexion Peak torque) records was significantly different pre training between sea level training (p<.05) and pre training between altitude training (p<.05) in β-ala group. But not Con group(placebo). In conclusion, efficiency of beta-alanine supplementation were increased a beneficial effect on 200m swim performance(aerobic capacity) and isokinetic’s muscle power in elite swimmers.
