摘要

Purpose: The study was to investigate the effects of 6 weeks of intensity intermittent training (IT) on lactate (La) responses to 400 m track running. Methods: Seven male sprinters were volunteers as the study subjects. Their average age, height, and weight were 22.9±2.5 yrs, 176.7±6.0 cm, 71±5.8 kg, 7.7±2.0 yrs, respectively. All of the subjects performed 2 times of 300 m sprint run, 2 days, and 6 weeks IT. The data of La was test at pre and post experiment. The La was measured at immediate, 3, 5, 7, 10, 12 min after 400 m run, respectively. Repeated-measures t-test was used in this study, significance was determined at an α level of 0.05. Results: The findings are as follows: First of all, the La for 3, 5, 7, 10, 12 min of recovery time were significant higher than immediate after 400 m track running (p＜.05). The lactate values of pre-exercise was lower than post-exercise, but no significant (p＞.05). The rang of lactate values were 18.13 mmol to 22.17 mmol. in pre-exercise and 18.49 mmol to 19.43 mmol in post- exercise. Conclusion: Two times of 300 m sprint run, 2 days, 6 weeks of HT slight improved the sprinter's blood lactate and 400 m performance.
