目的:本研究目的在探討4週的羽球米字步間歇訓練對大學男子羽球選手生理指標及膝屈伸肌比值之影響。方法:以8名大學甲組選手作為研究對象，進行四週，每周兩次的高強度間歇訓練，所有研究者於實驗前、後皆進行有氧及無氧測驗，且測量安靜、立即血乳酸、VO2max、安靜及結束心跳率。所得資料以SPSS18.0相依樣本t考驗及Pearson’s績差相關分析比較，所有顯著水準設為α=.05。研究結果:本研究結果在安靜、立即血乳酸皆達顯著差異（p<.05）；VO2max訓練後顯著優於訓練前；安靜、結束心跳率均有降低的情形，皆無顯著差異。慣用腳與非慣用腳伸肌皆大於屈肌，但無顯著差異（p>.05）。屈/伸肌比值為74.35%~93.22%、伸肌/伸肌比值為100.75%~107.07%與屈肌/屈肌比值為101.98%~116.40%。結論:本研究研顯示為其四週高強度間歇訓練訓練後對血乳酸、VO2max、心跳率皆有顯著提升的效果，進而提升運動表現。屈/伸肌比值均符合肌力平衡，慣用腳/非慣用腳肌力比值差異皆相近或低於10%。本研究所得之屈/伸肌比值可提供檢視肌肉不平衡之參考指標，以預防傷害產生。
Purpose: The aim of this study was to examine the effects of a 4-week six points high intensity interval training on physiological parameters and knee flexor-extensor torque ratios in collegiate male badminton players. Method: Complete data were collected from 8 college badminton players who volunteered to participate in this study and the training was performed two times a week. Subjects completed a 4-week intervention period that consisted of performing the high intensity interval training. Subjects were measured for the mean value of aerobic and anaerobic before and after the experiment. Blood lactate, heart rates measurements were primarily taken from resting and acute after experiment. VO2max measurements were also included in this experiment and the significant level α=.05. The data was analyzed by paired t-test and Pearson product moment correlation. Results: Data showed a significant was found in blood lactate from resting and acute (p<0.05). There were no other significant differences in the heart rate and VO2max (p>.05). After the experiment. The peak torque (PT), flexor-extensor ratios (F/E ratios) and reciprocal peak torque ratios (E/E ratios and F/F ratios) were no significant (p>.05). PT of knee extensor was higher than flexor, but no significant (p>.05). The F/E ratios ranged from 74.35 to 93.22%, E/E ratios ranged from 100.75 to 107.07%, F/F ratios ranged from 101.98 to 116.40%. Conclusions: The findings indicated that based on the high intensity interval training for a 4-week period investigated, effected and significantly improved in blood lactate tolerance level, VO2max and heart rate, as well as specific sport performance for badminton players. The present study indicate that the PT, F/E ratios, E/E ratios and F/F ratios were not influenced by age and training background in the knee of the badminton players. Which may provide a guide to observe muscle imbalance which could be a factor in injury.
