[ 摘要 ]
本研究目的旨在探討，速度變換之間歇訓練對5000m專項成績之影響。受試者對象為七位高中男生田徑長跑隊選手，平均年齡17.2±0.69 year，身高171.9±0.39 cm，體重57.9±5.04 kg，訓練年數3.7±1.63 year。訓練時間為四週，每週四次，以70%、80%、90% 不同強度作400m變換速度之間歇訓練。採用相依樣本t考驗、簡單以及回歸四象限進行統計分析，探討在四週作速度變換之間歇訓練後，選手的基礎耐力能力及5000m專項成績之差異及相關情況，顯著水準 p<0.05。研究結果：基礎耐力測試 (2-4mmol/l) ：實施四週間歇訓練結束後，受試者之有氧、無氧閾値 (2-4mmol/l) 速度提升，達顯著差異 (p<0.05) ；心跳率皆未達顯著差異 (p>0.05) 。訓練適應：恢復心跳率，5000m運動結束後 (E5) 心跳率低於120min-1。有氧耐力能力有顯著改善 (p<0.05) 。乳酸排除速度及心跳率，經四象限相關分析，有明顯降低的趨勢，皆向右下D區移動。400m最大速度與5000m最後400m (last)之關係：後測單項400m成績，達顯著相關 (p<0.05)。後測400m最大速度與5000m最後400m(last)速度之相關 r2=0.78，達顯著相關 (p<0.05)。無氧閾值(4mmol/l)速度與5000m專項成績之關係：無氧閾值速度與5000m的速度皆明顯的進步，5000m專項成績，有達顯著相關 (p<0.05) 。經直線回歸分析，無氧閾値與專項成績之相關値為 r 2=0.21，未達顯著相關 (p>0.05) 。結論：由本研究結果得知，四週速度變換之間歇訓練，對高中中長跑選手的基礎耐力、乳酸排除速度、速度、速度耐力及專項成績，皆有提升之效果。

The purpose of the study was to investigate the effects of interval training with speed shifting on the 5000 m running performance. Seven male long-distance athletes of high school level as subjects whose average age, height, weight and training years were 17.2 ± 0.69 year, 171.9 ± 0.39 cm, 57.9 ± 5.04 kg and 3.7 ± 1.63 year, respectively, and all subjects participated 4 times a week and totally 4 weeks of training period. Different intensities of 70%、80% and 90% of the best personal 400m performance were used as interval training with different shifting patterns. Statistical analyses of repeated measure t-test, simple regression and four quadrants were used to evaluate the differences and correlations of personal basic endurance capacity and 5000m running performance after 4 weeks training. All significant level were set at p<0.05. The results showed (1) 2-4mmol/l personal threshold test: all subjects improved significantly (p<0.05) on personal aerobic-anaerobic threshold capacities, but didn’t on heart rate (p>0.05). (2) Training adaptation: recovery heat-rate after 5000m run performance was below 120 min-1 ; there was a significant improvement at aerobic endurance (p<0.05); Lactate elimination and heart-rate improved significantly (p<0.05), and showed a positive movement toward D area on four quadrants analysis. (3) The relationship between maximum speed of 400m run and the last 400m of 5000m run, which reached a significant correlation r2=0.78 (p<0.05). (4) The relationship between anaerobic threshold capacity (4mmol/l) and 5000m run reached significant correlation (p<0.05).
Anaerobic threshold capacity had no significant correlation with 5000m run performance (p>0.05). Conclusion: according to results of this study, 4 weeks interval training with speed shifting showed positive effects on basic endurance, lactate elimination, speed, speed endurance and 5000m run performance, respectively
