조정 선수의 무산소성 웜업 강도가 혈중젖산 및 운동수행능력에 미치는 영향

초록

The purpose of this study was to investigate the effects of warm up(WU) intensity on the blood lactate and exercise performance on rower. Pre-test measured VO2max, HRmax of test subjects based on Bruce protocol on treadmill, and set heart rate of WU intensity of each subjects. As for the main test, the subjects conducted rowing ergometer for1 minutes per each WU intensity and had 2 minutes of rest. After3 minutes of resting, they conducted 2,000m rowing ergometer in full power, and had 2,5,10minutes of after the ergometer. There were total 7 lactate measuring. WU intensity 80~90% group lactate was significantly higher than WU intensity50-60%group. In 3min after WU, the WU intensity 80~90% group lactate was significantly higher than WU intensity 50~60% group and WU intensity 65~75% group. In 10min after 2,000m rowing ergometer, WU intensity 50~60% group lactate was significantly higher than WU intensity 80~90% group. Result showed that warm up intensity was increased in anaerobic power(minimum power) in WU intensity 65~75% group than WU 50~60% group and 80~90% group. Thus, suggest that for high intensity sports like rowing, it’s highly likely that the lactate secretion from mid-high intensity pre-warm up before game decreased lactate secretion during game, and thus, it could contribute top laying game as an energy source rather than a fatigue substance.
