Abstract

PURPOSE

The aim of this study was to investigate physiological responses and energetic contributions during simulated epée matches in elite fencers.

METHODS

Ten elite male fencers participated in simulated epée (direct elimination) matches. Simulated epée matches included 3 bouts of 3 minutes each with 1-minute rests between bouts. During these sessions, physiological variables such as mean and peak heart rate, peak and mean oxygen uptake (VO2peak and VO2mean), metabolic equivalents of task in VO2peak and VO2mean, and blood lactate concentrations (peak lactate concentration and delta blood lactate concentration) were measured. Furthermore, energetic contributions (oxidative [WOxi], glycolytic, and phosphagen) and time-motion variables were estimated.

RESULTS

Values of peak heart rate, mean heart rate, and WOxi (in percentages) were significantly higher in the second and third bouts compared with the first. VO2peak and metabolic equivalents of task in VO2peak were significantly higher in the first bout compared with the third bout. Values of delta blood lactate concentration and glycolytic contribution (in kilojoules and percentages) were significantly lower in the second and third bouts compared with the first. VO2mean and metabolic equivalents of task in VO2mean were significantly higher in the second bout compared with the third bout. Furthermore, WOxi (in kilojoules and percentage) was significantly higher in all bouts compared with phosphagen and glycolytic contributions. Low positive and negative correlations were seen between WOxi, VO2mean, sum of attacks and defense times, and the sum of time without attacks and defenses.

CONCLUSIONS

Direct-elimination epée matches consist of high-intensity intermittent exercise, and the oxidative contribution is 80% to 90%. Improving aerobic conditioning may support high-intensity intermittent actions during entire epée matches in elite fencers.

摘要

目的

本研究旨在调查精英击剑运动员在模拟重剑比赛中的生理反应和能量贡献。

方法

10 名精英男性击剑运动员参加了模拟重剑(直接淘汰赛)比赛。模拟重剑比赛包括 3 个 3 分钟的回合,每个回合之间休息 1 分钟。在这些回合中,测量了生理变量,如平均心率和峰值心率、峰值和平均耗氧量(峰值耗氧量和平均耗氧量)、峰值耗氧量和平均耗氧量的代谢当量、血乳酸浓度(峰值血乳酸浓度和血乳酸浓度差)。此外,还估计了能量贡献(氧化[WOxi]、糖酵解和磷酸原)和时间运动变量。

结果

与第一回合相比,第二和第三回合的峰值心率、平均心率和 WOxi(百分比)显著升高。与第三回合相比,第一回合的峰值耗氧量和峰值耗氧量的代谢当量更高。与第一回合相比,第二和第三回合的血乳酸浓度差和糖酵解贡献(以千焦耳和百分比表示)显著降低。与第三回合相比,第二回合的平均耗氧量和平均耗氧量的代谢当量更高。此外,与磷酸原和糖酵解贡献相比,所有回合的 WOxi(以千焦耳和百分比表示)均显著升高。WOxi、平均耗氧量、攻击和防守时间总和以及无攻击和防守时间总和之间存在低正相关和负相关。

结论

直接淘汰赛重剑比赛由高强度间歇运动组成,氧化贡献为 80%至 90%。提高有氧能力可能有助于精英击剑运动员在整个重剑比赛中进行高强度间歇运动。
