目的：增加最大摄氧量(（V)超过dotO(2)max）和跑步经济性可以提高长跑运动员的表现。然而，长跑运动员需要冲刺才能获胜，尤其是在比赛的最后阶段。作者确定了成绩与短跑能力之间的关系，以及优秀长跑运动员的其他能力。方法：以12名优秀长跑运动员为研究对象。考试前后一年内5000米（5000米- sb）和10000米（10000米- sb）比赛的官方平均季节最佳成绩分别为13:58.5（0:18.7）和28:37.9 (0:25.2)（Mean [SD]）。作者用100米和400米短跑次数作为短跑能力的指标。他们还测量了(V) / dotO(2)max和运行经济性((V) / dotO(2)在300 m.min（-1）的运行速度下。他们使用单一相关性分析来评估5000 m-SB或10,000 m-SB与其他元素之间的关系。结果：5000m - sb与100米冲刺时间（13.3 [0.7]s, r= 0.68， P= 0.014）、400米冲刺时间（56.6 [2.7]s, r= 0.69， P= 0.013）、跑步经济性(55.5 [3.9]mL.kg（-1).min(-1)）显著相关；r = 0.59， P= 0.045)。1万m-SB与100米冲刺时间（r= 0.72， P= 0.009）、400米冲刺时间（r= 0.85, P < 0.001）存在显著相关。然而，5000 m-SB或10000 m-SB与(V) / dotO(2)max (72.0 [3.8] mL.kg（-1).min(-1)）之间没有显著相关性。结论：短跑能力是优秀长跑运动员成绩的重要指标。
Purpose: Increases in maximal oxygen uptake ((V) over dotO(2)max) and running economy improve performance in long-distance runners. Nevertheless, long-distance runners require sprinting ability to win, especially in the final phase of competitions. The authors determined the relationships between performance and sprinting ability, as well as other abilities in elite long-distance runners. Methods: The subjects were 12 elite long-distance runners. Mean official seasonal best times in 5000-m (5000 m-SB) and 10,000-m (10,000 m-SB) races within 1 year before or after the examination were 13:58.5 (0:18.7) and 28:37.9 (0:25.2) (mean [SD]), respectively. The authors measured 100-m and 400-m sprint times as the index of sprinting ability. They also measured (V) over dotO(2)max and running economy ((V) over dotO(2) at 300 m.min(-1) of running velocity). They used a single correlation analysis to assess relationships between 5000 m-SB or 10,000 m-SB and other elements. Results: There were significant correlations between 5000 m-SB was significantly correlated with 100-m sprint time (13.3 [0.7] s; r= .68, P= .014), 400-m sprint time (56.6 [2.7] s; r= .69, P= .013), and running economy (55.5 [3.9] mL.kg(-1).min(-1); r = .59, P= .045). There were significant correlations between 10,000 m-SB and 100-m sprint time (r= .72, P= .009) and 400-m sprint time (r= .85, P < .001). However, there was no significant correlation between 5000 m-SB or 10,000 m-SB and (V) over dotO(2)max (72.0 [3.8] mL.kg(-1).min(-1)). Conclusions: The authors' data suggest that sprinting ability is an important indicator of performance in elite long-distance runners.
