在网球运动中，教练认为平衡是获得熟练的运动能力的基础。然而，平衡与网球专业知识和表现之间的潜在关系还没有被探索。因此，本研究通过1)不同年龄、不同专业水平网球运动员的比较，以及2)分析平衡性与网球发球速度和准确度的关系，用线性和非线性参数评估了平衡性与网球成绩的关系。106名休闲和专业的男子网球运动员(年龄范围为10-35岁)参加了研究。通过平均速度和压力中心(COP)的去势波动分析，分析了不稳定表面平衡任务中姿态控制的时间动力学。网球发球表现通过测量精确度和速度来量化。衡量平衡能力的传统变量只显示出年龄的差异，而不是运动成绩。COP显示自相关变异性(由DFAV反映)随着年龄的增加而减少，但主要是在专家球员中。COP动态是区分运动技能的唯一平衡参数，且与年龄有关。专业网球运动员DFAV的结果支持了这样的观点，即多年来，运动经验诱导了平衡适应，其特征是执行姿势调整的能力更高。这些结果也加强了非线性分析的使用，以揭示运动实践产生的微妙的平衡适应。最后，缺乏相关性表明，在非特定任务中，用分散变量衡量的平衡并不是网球发球运动表现的主要决定因素。
In tennis, coaches consider balance fundamental for the acquisition of skilled motor performance. However, the potential relationship between balance and tennis expertise and performance has not been explored yet. Therefore, this study assessed the relationship between balance and tennis performance using linear and non-linear parameters through 1) the comparison of tennis players of different ages and levels of expertise, and 2) analyzing the relationship between balance and tennis serving speed and accuracy. One hundred and six recreational and expert male tennis players took part in the study (age range 10–35 years old). Temporal dynamics of postural control during a balance task on an unstable surface were analyzed through the mean velocity and the detrended fluctuation analysis (DFAV) of center of pressure (COP). Tennis serve performance was quantified by measuring accuracy and speed. Traditional variables measuring balance performance only showed differences according to age but not to sport performance. COP showed a reduction of auto-correlated variability (reflected by DFAV) with age but mainly in expert players. COP dynamics was the only balance parameter discriminating sport expertise and it was related to age. Balance dynamics exhibited by expert tennis players DFAV results support the idea that, along the years, sport experience induces balance adaptations characterized by a higher ability to perform postural adjustments. These results also reinforce the use of non-linear analysis to reveal subtle balance adaptations produced by sport practice. Finally, the lack of correlations suggests that balance, measured with scattering variables, in a non-specific task is not a main determinant of sport performance in tennis serve.
