Abstract: 目的:針對超級馬拉松24小時賽中兩位男性跑者,比賽中之步幅與步頻之個案研究。
方法:2007年東吳國際超級馬拉松24小時賽中,日本籍選手關家良一先生(Ryoichi Sekiya),及我國選手吳勝銘先生兩人作為研究對象,在24小時賽中用攝影方法拍攝跑者之步態,然後以運動動作分析系統(SiliconCOACH)加以分析資料,所獲得資料以描述性統計及獨立樣本t檢定進行分析。
一、結果
(一)關家良一選手每小時平均跑11.45公里,吳勝銘選手每小時平均跑9.01公里。
(二)兩位選手的平均速度都隨時間愈長而漸慢,且兩位跑者的速度變慢直到第18小時以後才又恢復。
(三)吳勝銘的步頻(1.60步/秒)顯著高於(p<.05)關家良一的步頻(1.49步/秒);但吳勝銘的步幅 (1.58公尺)和平均速度(2.55公尺/秒)均顯著低於(p<.05)
關家良一的步幅(1.93公尺)和平均速度(2.90公尺/秒)。
(四)在步態週期耗時方面,除左腳騰空期耗時之外,吳勝銘與關家良一在右腳支撐期耗時(0.258 vs. 0.275秒)、左腳支撐期耗時(0.247 vs.0.276秒)和右腳騰空期耗時(0.064 vs. 0.056)均有顯著差異(p<.05)。
二、結論
(一)步幅對於速度的影響大於步頻。
(二)下肢長可做為選才之參考。
(三)賽前宜調整生理時鐘以提升成績。
The purpose of this study is to compare the running speed, stride length, and stride rate of two male runners in 24-hr Ultra-marathon race. The two male ultra-marathon runners, Ryoichi Sekiya from Japan and Sheng-Ming Wu from Taiwan, who participated in 2007 Soochow University International 24-hr Ultra-marathon race were recruited. The runners’ stride performances were video-recorded and analyzed by SiliconCOACH motor analyzing system. We found: (1) The average hourly running speed for Ryoichi and Wu is 11.45 and 9.01 km/hr, respectively; (2) The average stride length of Sekiya is significantly longer than Wu, 1.93 and 1.58 meters, respectively (p<.05); (3) The average stride rate of Sekiya is significantly lower than Wu, 1.49 and 1.60 strides/second, respectively (p<.05); (4) Both runners’ speed gradually reduced during the first 18 hours; however, the speed was recovered from the 19th hour; (5) The time spent during the stride cycle is also significantly different between two runners. Sekiya spent less time during the stance phase than Wu (right leg: 0.258 vs. 0.275 sec.; left leg: 0.247 vs.0.276 sec., p<.05). However, Sekiya had longer flight phase of right leg than Wu (0.064 vs. 0.056 sec., p<.05).
In conclusion, stride length is more critical than stride rate to improve the running speed. Runners with longer lower limbs may have the advantage on the running race. Finally, runners should adjust their physiological circadian clock in advance to improve their running performance.
