馬拉松賽事中跑者疲勞對著地模式之影響
Effects of Marathon Fatigue on Running Strike Patterns.
摘要
目的：探討馬拉松賽事中跑者的著地模式是否會隨著速度的快慢是否會有不同的著地模式。方法：本實驗賽事中利用高速攝影機收錄賽道上前13位跑者做著地模式的分析及比較不同速度對著地模式之影響。本研究使用重複量數單因子變異數分析，顯著水準訂為α = .05。結果:在比賽當中隨著比賽距離的增加，因疲勞所以使用後足著地的跑者也越多，在平均配速方面使用中前足著地的跑者配速會比使用後足著地的跑者平均配速快17秒。結論: 隨著跑步速度的降低，使用後足著地的跑者百分比增加；相反的，隨著跑步速度的增加，中前足著地的跑者百分比也增加，但對使用中前足著地的跑者，建議進行下肢增強式訓練及小腿的離心負荷訓練，以避免運動傷害以及增進運動表現。

Purpose: The purpose of this study was to investigate whether marathon runners'footstrike pattern would differ along with different running speed. Methods: A major marathon event was selected for the experiment trail. High speed cameras were instrumented to record down the top thirteen runners' footstrike patterns for analysing the relationship between running speed and footstrike patterns. The one-way repeated ANOVA had been carried out for statistical measurement, the level of significance was set as α=.05. Results: With the mileage mounted, more runners swapped into rearfoot landing patterns due to fatigue. On the aspect of average pacing, runners who implemented midfoot and forefoot landing patterns have a faster pace of 17 seconds on average than those who adopted rearfoot landing patterns. Conclusion: The percentage of runner adopted rearfoot landing pattern has increased as their running speed decreased. On the opposite, with the increase in running speed, more population adopted midfoot and forefoot landing pattern. To those forefoot- and midfoot-landing runners, it was suggested that adding lower limb plyometric training and eccentric contraction training for calf muscles to not only minimize the risk of injuries and increase performance as well.
