加速規監控優秀馬拉松選手的配速策略

馬拉松運動並非短時間就可以立即參與的運動，它是需要相當的經驗及訓練，馬拉松比賽中配速的好壞是比賽中的關鍵，依照個人能力的不同、地形、環境、氣候等因素，配速上會有不同的方式出現。研究目的:探討加速規應用正式比賽上的配速監測及探討並用選手本體感覺、心跳率及高度來輔助運動強度的監控。方法:一、使用加速規全程監測選手比賽情況，並同時使用Polar錶監測心跳率、海拔高度，賽後填寫運動自覺量表節奏測驗，在400公尺場地上，分別以每分鐘150、180、210、240等四種節奏進行測驗，每種節奏跑一次原地休息5分鐘，以獲取四次節奏的頻率數據。研究結果:在跑步歷程小波轉換圖中可以發現到受試者在900-1600秒這段時間內的跑步頻率是較穩定的，跑動的過程中是相當有效率的，在1600秒過後，開始出現混亂的情況，呈現一個向上的曲線，曲線的集中度，隨著時間的拉長而顯得混亂，在3200秒時呈現混亂的圖形，嘗試著將四種頻率結合在一起時，發現到在3.26Hz情況下，每分鐘195步，受試者的能量使用情況在92%左右；在5公里時，受試者自覺程度為8非常輕鬆的狀態。10公里開始受試者自覺程度為12開始感到有些吃力15公里處受試者自覺程度為16感到吃力。大約16-20公里的區段受試者感到腳部有些不適。20公里處自覺程度為17感到非常吃力。研究結論:一、受試者現階段最佳的狀態應是3.26Hz，即每分鐘195步，最大能量的應用是在92%左右。二、透過自覺程度量表、心跳率及高度的輔助監測能有效瞭解受試者的運動強度，配合加速規的訊號，可以瞭解受試者的配速策略。

The marathon is a sport which requires a certain amount of experiences and training. The participant’s pace is the key element to winning a marathon. Pace can appear in different forms due to the individual’s ability, and influences of the, topography, environment and weather. The purpose of this study: This research is to study the application of an accelerometer to monitor the pace in formal marathon races, and to monitor how the intensity of the exercise is affected by the runner’s senses, heart rate and altitude. Use an acceleromete to monitor the runner’s condition during the entire race. In addition, use a Polar watch to monitor the runner’s heart rate, altitude and ensure the runner completes the RPE after the race. Method Two: Pace examinations: On a 400m running track, we do four trials of pacing, separately, using 150, 180, 210, 240 steps/ per minute. At the completion of each trial, a 5-minute break is taken in order to obtain the data from the four trials. The result of the study: According to the table of the Wavelet transform, we learnt that the running frequencies of the participants were more stable between 900 seconds to 1600 seconds and more efficient during this period. Above 1600 seconds, the frequency showed instability, the curve had become upward, and more unstable as the period of time extended. The graphic was thrown into disarray at 3200 seconds. Combining the four frequencies, we learnt that runners consumed 92% of energy usage at the pace of 195 steps per minutes at a frequency of 3.26HZ；At level 8, the runners felt that a distance of 5 kilometers was very easy. At level 12, the runners found it slightly more difficult up to a distance of 10 kilometers. At level 16, the runners felt it was very difficult over a distance of 15 kilometers. The runners’ legs felt very uncomfortable when they ran 16-20 kilometers. At level 17, the runners felt it was extremely difficult when they ran 20 kilometers. Result of the study: 1.The best condition for the runner was 3.26Hz, which was a pace of 195 steps per minute; the best consumption of energy usage was 92%. 2. strength of runner’s endurance can be monitored through RPE, heart rate and altitude, and the use The of an accelerometer can help the runner plan his/her pace before the marathon takes place.
