摘要

本研究目的是評估打網球可否延緩中老年人心肺功能的衰退，研究中有20位中老年打網球者自願參與。其中男性15位，平均年齡66±4歲52-82歲)；女性5位，平均年齡50±7歲40歲-59歲)。受試者球齡在兩年以上，每週至少從事三次以上的網球運動，每次運動時間至少30分鐘以上。受試者利用進階式踏車測試，測其攝氧量、二氧化碳呼出量、心搏率及換氣量等生理變數。並依其運動時呼吸氣體變數的變化，決定無氧閥值AnaerobIcThresholdl)。結果顯示網球運動可以明顯延緩中老年人心肺功能的衰退。男性受試者在兩年間最大攝氧量由33.5±11.8ml/kg/min略降至31.0±8.5ml/kg/min，女性受試者由27.7±3.7ml/kg/min略升至29.0±4.8m1/kg/min，但是統計上未呈明顯差異，此結果表示受試者的最大攝氧量在兩年中無明顯衰退。在無氧閥值時受試者的攝氧量、氧脈及工作率亦無明顯退步。本研究証實網球運動可以延緩中老年人心肺功能的衰退，是一項值得推廣的耐力性運動。

Objective: To evaluate the training effects of tennis on the maintenance of cardiorespiratory function in middleaged and older individual
Design: Prospective study of a cohort of older tennis players examined two years after initial examination
Setting: Research project at a hospital-based exercise physiology laboratory.
Participants: 15 male (mean age: 66±4 yrs, range: 52-82 yrs) and 5 female (mean age: 5O±7 yrs, range: 40-59 yrs)subject free of significant cardiovascular, pulmonary and musculoskeletal diseases completed this study.
Intervention: During the study period, the subjects practiced tennis 3-7 times per week. The baseline cardiorespira tory function was recorded in the initial exercise test. Same masurement was repeated two years later to determine the rate of decline in cardiorespiratory function.
Main outcome: The 2-year trends of cardiorespiratory function in both groups.
measure:
Results: The maximal oxygen uptake (VO2 max) decreased from 33.5±l1.8 mI.kg-l.min-l to 31.0±8.5ml.kgl,min.1 in the male, and it increased from 27. 7±3. 7 m1.kg- 1.min-l to 29.0±4.8ml.kg-l.min-l in the female. However, the rate of decline was statistically insignificant. At the anaerobic threshold (A 1). There was also no significant change in VO2
Conclusion: This data substantiates that regularly practicing tennis may delay the decline of cardiorespiratory function in the middle-aged and older individuals. In addition. Tennis may be prescribed as a suitable aerobic exercise for the senior citizen.
