High-fives are a phenomenon that is frequently observed in sports. However, investigations on effects of high-fives are missing. Therefore, the aim of the present study was to examine psychophysiological effects of high-fives. From an embodied cognition perspective, dynamic, upward movements compared to downward movements should activate positive concepts that are represented by psychological as well as physiological states. Thirty-four athletes performed high- and low-fives (dynamic movements) as opposed to high and low static postures (control conditions) in a double-blind, within-subject design. Psychological states (i.e., feeling motivated, feeling strong) and physiological changes (i.e., cortisol, testosterone) due to the manipulation were measured. Results showed the predicted significant interaction effect for cortisol changes, but not for the other psychological (i.e., feeling motivated, feeling strong) and physiological (testosterone) state measures. In detail, a decrease in cortisol was found after athletes performed high-fives compared to low-fives. The observed effect on cortisol should be considered with caution and needs to be replicated, however, might add information to the current discussion about the crucial relevance of movement for embodied cognition effects. Future research could investigate the effects of high-fives with a partner and add performance parameters to provide more information on the effects of high-fives on performance in sport.

击个掌？检查高强度击剑运动员的心理生理效应。

高强度击打是一种在体育运动中经常观察到的现象。但是，有关击打五指的影响的研究仍未进行。因此，本研究的目的是检查高强度击掌的心理生理效应。从具体的认知角度来看，与向下运动相比，动态的向上运动应激活以心理和生理状态为代表的积极观念。在双盲，受试者内部设计中，有34名运动员进行了高强度和低强度的运动（动态动作），而高静态姿势和低静态姿势（控制条件）相反。测量了由于操作而引起的心理状态（即动力，坚强）和生理变化（即皮质醇，睾丸激素）。结果表明，预测的相互作用对皮质醇有显着影响，但不适用于其他心理（即上进，坚强）和生理（睾丸激素）状态的指标。详细地，与低强度运动员相比，高强度运动员在进行高强度拳后发现皮质醇减少。观察到的对皮质醇的影响应谨慎考虑，需要加以复制，但是，可能会为当前的讨论增加信息，说明运动与具体的认知作用的关键相关性。未来的研究可能会与搭档一起研究击掌的影响，并添加性能参数，以提供有关击掌对运动表现的影响的更多信息。观察到的对皮质醇的影响应谨慎考虑，需要加以复制，但是，可能会为当前的讨论增加信息，说明运动与体现的认知作用的关键相关性。未来的研究可能会与搭档一起研究击掌的影响，并添加性能参数，以提供有关击掌对运动表现的影响的更多信息。观察到的对皮质醇的影响应谨慎考虑，需要加以复制，但是，可能会为当前的讨论增加信息，说明运动与体现的认知作用的关键相关性。未来的研究可能会与搭档一起研究击掌的影响，并添加性能参数，以提供有关击掌对运动表现的影响的更多信息。
