Priming exercises improve subsequent motor performance; however, their effectiveness may depend on the workload and involved body areas. The present study aimed to estimate the effects of leg and arm priming exercises performed at different intensities on maximal sprint cycling performance. Fourteen competitive male speed-skaters visited a lab eight times, where they underwent a body composition measurement, two V̇O measurements (leg and arm ergometers), and five sprint cycling sessions after different priming exercise conditions. The five priming exercise conditions included 10-minute rest (Control); 10-minute arm ergometer exercise at 20% V̇O (Arm 20%); 10-minute arm ergometer exercise at 70% V̇O (Arm 70%); 1-min maximal arm ergometer exercise at 140% V̇O (Arm 140%); and 10-min leg ergometer exercise at 70% V̇O (Leg 70%). Power outputs of 60-s maximal sprint cycling, blood lactate concentration, heart rate, muscle and skin surface temperature, and rating of perceived exertion were compared between the priming conditions at different measurement points. Our results showed that the Leg 70% was the optimal priming exercise among our experimental conditions. Priming exercise with the Arm 70% also tended to improve subsequent motor performance, while Arm 20% and Arm 140% did not. Mild elevation in blood lactate concentration by arm priming exercise may improve the performance of high-intensity exercise.
预热练习可以提高后续的运动表现；然而，其效果可能取决于工作量和涉及的身体部位。本研究旨在评估在不同强度下进行的腿部和手臂预热练习对最大冲刺自行车性能的影响。14 名男性速滑运动员在实验室接受了 8 次访问，在那里他们接受了身体成分测量、两次 V̇O 测量（腿部和手臂测力计）以及在不同预热练习条件下进行了五次冲刺自行车骑行。这五种预热练习条件包括 10 分钟休息（对照）；10 分钟手臂测力计运动，强度为 20%V̇O（手臂 20%）；10 分钟手臂测力计运动，强度为 70%V̇O（手臂 70%）；1 分钟最大手臂测力计运动，强度为 140%V̇O（手臂 140%）；10 分钟腿部测力计运动，强度为 70%V̇O（腿部 70%）。在不同的测量点比较了预热条件下 60 秒最大冲刺自行车的功率输出、血乳酸浓度、心率、肌肉和皮肤表面温度以及感觉用力程度。我们的结果表明，腿部 70%是我们实验条件下的最佳预热练习。手臂 70%的预热练习也有助于提高后续运动表现，而手臂 20%和手臂 140%则没有。手臂预热练习引起的血乳酸浓度轻度升高可能会提高高强度运动的表现。
