摘要

背景:衰老导致身体系统的功能改变。目的:本研究旨在探讨老年人网球发球的时间模式、时间变异性和时间规律性的年龄差异。研究设计:横断面研究。研究样本:本研究的参与者是年轻人(n = 10)和老年人(n = 11)的志愿者,他们自定义为非竞争性,每周定期参加2-3天的休闲(亚精英)水平的网球。数据收集:他们被要求在一个常规大小的场地上对相同的发球(平球、削球或上旋球)进行20次试验。使用高速数码相机记录和分析发球动作的时间(持续时间)。参与者在网球场上进行日常训练时进行网球发球。在进行服务之前,他们进行了结构化的一般活动(10分钟)和特定的热身活动(10分钟)。试验之间有30秒的休息时间。结果:研究结果显示,两组在时间模式上没有统计学上的显著差异,而年轻组在动作的某些阶段比老年人表现出更高的变异性和规律性/一致性。结论:由于长期的锻炼效果,参加娱乐性运动的老年人能够保留一些知觉运动能力的功能性组织,如时间。研究结果表明,参与体育运动可能有助于维持衰老后的功能性运动组织,以减轻成年后期与年龄相关的感知和行动能力下降。

Preservation of Temporal Organisation of Tennis Service Following Ageing in Recreational Players.

Background: Ageing leads to functional changes in body systems. Purpose: This study sought to examine the age-based differences in temporal patterning, temporal variability and temporal regularity of tennis service in older adults. Research design: cross-sectional study. Study sample: Participants of this study were volunteers from young (n = 10) and older (n = 11) adults who were self-defined as non-competitive, participating in tennis at a recreational (sub-elite) level for 2-3 days per week regularly. Data collection: They were asked to perform 20 trials of the same serves (flat, slice or top-spin) on a regular size court. The timing (duration) of the serve action was recorded and analysed, using a high-speed digital camera. Participants performed the tennis serves during their routine training sessions on a tennis court. They undertook a structured general (10min) and a specific warm-up routine (10min) before performing services. There was a 30-second rest period between trials. Results: Findings showed that there were no statistically significant differences between the two groups in temporal patterning, whereas the younger group performed the serves with higher variability and regularity/consistency than the older adults in some phases of the action. Conclusion: Older adults who participate recreationally in sports are able to preserve some functional organisation of perceptual-motor capacities, such as timing, due to long-term practice effects. The findings illustrate how sport participation may help maintain functional movement organisation following ageing to mitigate age-related declines in perception and action in late adulthood.
