本研究目的在於敘述中長跑者之運動表現、成績紀錄、運動強度與心跳恢復之間的關係，因此針對24名男性大學生進行研究。本研究將24名受試者分為兩組，分別為中長跑選手具有運動習慣的大專體育院校學生12名，及現役中長跑選手12名，測試與分析受試者運動成績、運動強度與心跳率分為前、中、後3個階段。研究結果顯示兩組的受試者在測試中半段所花的時間都是最多的，而且兩組的心跳速率都逐漸增加。然而中長跑選手的耐力與配速能力都優於具有運動習慣的大學生，因此可以在最後階段衝刺加速。另外，中長跑選手的心跳恢復到正常狀態的速度也比俱有運動習慣的大學生快。根據上述，本研究結論如下：較佳的耐力與配速能力是影響從事中長跑者表現的關鍵。

　　To elucidate relationship between performances﹐records﹐exercise intensity and recovery﹐heart rates﹐the 24 collegiate males were recruited﹐The speeds﹐intensities and heart rate in three stages﹐including 12 medium distance running players group(MDRP) and 12 collegiate students (CS) group with habitual exercise. The heart rates were monitored and recorded during 1500 meter run. The speed﹐intensities and heart rate in three stages were analyzed. Both of two groups take the most time in middle stage however﹐the MORP group can keep great endurance﹐capacity rather than CS group to speed up in the last stage. Both of two groups in creased the heart rate with the time. The strategy of adjustment stages in MDRP group was better than SL group. The faster recovery heart rates in MDRP group. In conclusion﹐greater endurance capacity and better strategy of adjustment in speed were the crucial factors for performances in medium distance running.
