To achieve high performance, wheelchair fencing (WF) athletes are required to exhibit good physiological and timing indicators. The main aims of this study were to assess the relationship between the results of the repeated sprint ability (RSA) test and reaction time (RT) in WF, and to evaluate changes in RT after repeated high-intensity sprints in the group of an international-level WF athletes. This experimental study involved 18 athletes (aged 34.6 ± 7.70) from the Paralympic WF team. To establish the impact of fatigue on psychomotor capacity, the participants undergo a series of tests. At the beginning of the study, first reaction time (RT1) was measured. Afterwards, the RSA test was performed using the arm crank ergometer to evaluate the participants' repeated sprint ability. Immediately after RSA, the second reaction time (RT2) was measured. Statistical analysis revealed moderate correlations between the RT2 and total work, decrease of work (DW), highest peak power, mean peak power, and highest peak power/kg, but these correlations were not statistically significant (p > 0.05). All fencers achieved a significantly shorter average RT2 (p < 0.005) after the RSA test (0.383 ± 0.035 s) than before the test (0.391 ± 0.038 s). Additionally, RT2 was significantly shorter than RT1 in the women's group (p < 0.001). Moreover, males had significantly greater values of repeated sprint ability parameters: highest work, total work, decrease of work and highest peak power (p < 0.05) than females. To conclude, repeated high-intensity arm crank exercise has a positive impact on simple postexercise cognitive tasks in WF fencers, especially in women, and leads to a decrease in RT. The RSA parameters can be predictors of changes in RT in men and women wheelchair fencers.
为了达到高性能，轮椅击剑（WF）运动员需要表现出良好的生理和定时指标。本研究的主要目的是评估 WF 中重复冲刺能力（RSA）测试和反应时间（RT）之间的关系，并评估国际水平 WF 运动员组中重复高强度冲刺后的 RT 变化。这项实验研究涉及 18 名运动员（年龄 34.6±7.70 岁）来自残奥会 WF 队。为了确定疲劳对心理运动能力的影响，参与者接受了一系列测试。在研究开始时，测量了第一反应时间（RT1）。之后，使用臂曲柄测功计进行 RSA 测试，以评估参与者的重复冲刺能力。在 RSA 之后，立即测量第二反应时间（RT2）。统计分析显示，RT2 与总功、功下降（DW）、最高峰值功率、平均峰值功率和最高峰值功率/公斤之间存在中度相关性，但这些相关性没有统计学意义（p>0.05）。所有击剑运动员在 RSA 测试后（0.383±0.035 秒）的平均 RT2 明显缩短（p<0.005），而在测试前（0.391±0.038 秒）的平均 RT2 明显缩短（p<0.005）。此外，女性组的 RT2 明显短于 RT1（p<0.001）。此外，男性的重复冲刺能力参数值明显大于女性：最高功、总功、功下降和最高峰值功率（p<0.05）。总之，重复高强度臂曲柄运动对 WF 击剑运动员的简单运动后认知任务有积极影响，尤其是女性，并且导致 RT 下降。RSA 参数可以预测男女轮椅击剑运动员 RT 的变化。
