This research aim to investigate the effects of motor imagery (MI), focused on the trajectory of the ball and the target area, and self-talk (motivational function) before the actual strike on the performance of the service in skilled tennis players. Thirty-three participants (6 females and 27 males, = 15.9 years), competing in regional to national competitions, were randomly divided into three groups: Control, MI, and MI + self-talk. They performed a pre-test (25 first service), 20 acquisition sessions (physical trial, physical trial + MI and physical trial + MI + self-talk), and a post-test similar to the pre-test, in match situations. The percentage of the first service, their speed, and the efficiency scores, evaluated by experts, were use as dependent variables and indicators of performance. While there was no difference in service speed ( > 0.05), this study showed an improvement in the first service percentage and efficiency (all ps < 0.01) in the participants of the MI and MI + self-talk groups. Additionally, analyses revealed greater efficiency when MI was combined with self-talk compared to other conditions. It, therefore, seems advantageous for skilled tennis players to use MI and motivational self-talk before performing the first service balls.
本研究旨在调查针对熟练网球运动员发球表现，聚焦于球的轨迹和目标区域的运动想象（MI）以及实际击球前的自我对话（激励功能）的影响。33名参与者（6名女性和27名男性，平均年龄=15.9岁），参加地区到全国性比赛，被随机分为三组：对照组、运动想象组和运动想象+自我对话组。他们在比赛情境中进行了一次预测试（25次一发）、20次习得训练（身体练习、身体练习+运动想象和身体练习+运动想象+自我对话）以及一次与预测试类似的后测试。一发的百分比、速度以及由专家评估的效率得分被用作因变量和表现指标。虽然发球速度没有差异（p>0.05），但本研究表明运动想象组和运动想象+自我对话组参与者的一发百分比和效率有所提高（所有p值<0.01）。此外，分析显示与其他条件相比，运动想象与自我对话相结合时效率更高。因此，对于熟练的网球运动员来说，在发第一发球之前使用运动想象和激励性自我对话似乎是有利的。
