本研究目的在探討足球8分鐘搶截訓練的心跳率變化，並比較其差情形。受試者為8位18~24歲正在訓練期的優秀女子足球選手，利用心律遙測器Polar測量受試者搶截訓練時的心跳率，做為本研究運動強度的指標。結果發現，受試者8分鐘搶截訓練之平均心跳率為171.8±18.3次/分，達其最大心跳率（196.0±8.2次/分）87.7%，這當中前3分鐘心跳率在最大心跳率66.4~88.8%之間，而後5分鐘心跳率已達最大心跳率90%以上。另外，1~2分鐘（含）以後的每分鐘心跳率都顯著（p<.05）高於0~1分鐘（130.2±102次/分），6~7分鐘（183.0±6.5次/分）與7~8分鐘心跳率（184.4±6.8次/分）也顯著（p<.05）高於1~2分鐘（166.8±8.6次/分）。本研究資料顯示，優秀女子足球選手進行8分鐘搶截訓練的心跳變化情形，可反應出此項訓練的運動程序。

The purpose of this study was to investigate the heart rate variation on 8 min of interception training (IT) in soccer. Eight 18-to 24-y old elite female soccer players were measured heart are rate (HR) by the Polar Sport Tester. During the 8 min of IT was 171.8±2.3beats/min, 87.7% of maximum HR (196.0±2.9 beats/min), and the final 5 min was over 90% of maximum HR. Additionally, after 1-2 min was significantly (p<.05) higher than the 0-1 min HR (130.2±10.2 beats/min), the HR of 6-7 (183.0±6.5 beats/min) and 7-8 min (184.4±6.8 beats/min) were significantly (p<.05) higher than the 1-2 min HR (166.8±8.6 beats/min). In conclusion, the HR variation on 8 min of IT in elite female soccer player can be sued as.
