Coaching aims to improve player performance and coaches have a number of coaching methods and strategies they use to enhance this process. If new methods and ideas can be determined to improve player performance they will change coaching practices and processes. This study investigated the effects of using low compression balls (LCBs) during coaching sessions with beginning tennis players. In order to assess the effectiveness of LCBs on skill learning the study employed a quasi-experimental design supported by qualitative and descriptive data. Beginner tennis players took part in coaching sessions, one group using the LCBs while the other group used standard tennis balls. Both groups were administered a skills at the beginning of a series of coaching sessions and again at the end. A statistical investigation of the difference between pre and post-test results was carried out to determine the effect of LCBs on skill learning. Additional qualitative data was obtained through interviews, video capture and the use of performance analysis of typical coaching sessions for each group. The skill test results indicated no difference in skill learning when comparing beginners using the LCBs to those using the standard balls. Coaches reported that the LCBs appeared to have a positive effect on technique development, including aspects of technique that are related to improving power of the shot. Additional benefits were that rallies went on longer and more opportunity for positive reinforcement. In order to provide a more conclusive answer to the effects of LCBs on skill learning and technique development recommendations for future research were established including a more controlled experimental environment and larger sample sizes across a longer period of time. Key PointsLCB may aid skill learning in tennis.Qualitative indicators.Statistical evidence not conclusive.Further studies of larger groups recommended.
教练的目的是提高运动员的表现，为此他们会使用多种教练方法和策略。如果能确定新的方法和理念来提高运动员的表现，那么教练的实践和流程将会发生改变。本研究调查了在初级网球运动员的训练课程中使用低压缩球（LCB）的效果。为了评估 LCB 对技能学习的有效性，本研究采用了准实验设计，并辅以定性和描述性数据。初级网球运动员参加了教练课程，一组使用 LCB，另一组使用标准网球。两组在一系列教练课程开始时和结束时都进行了技能评估。通过统计分析前测和后测结果之间的差异，确定 LCB 对技能学习的影响。通过访谈、视频捕捉和对每组典型教练课程的表现分析，获得了额外的定性数据。技能测试结果表明，使用 LCB 的初学者和使用标准球的初学者在技能学习方面没有差异。教练报告称，LCB 似乎对技术发展有积极影响，包括与提高击球力量相关的技术方面。此外，回合时间更长，获得积极反馈的机会更多。为了更明确地回答 LCB 对技能学习和技术发展的影响，建议进行未来的研究，包括在更长的时间内使用更受控的实验环境和更大的样本量。要点：LCB 可能有助于网球中的技能学习。定性指标。统计证据不具结论性。建议对更大的群体进行进一步研究。
