本研究主要目的是比較有無規律網球運動老年人身體活動量與平衡能力之差異。甄選40位規律從事網球運動(網球組) 和40位無規律運動(對照組)男性老年人為研究對象，平均年齡65.1 ± 3.5歲。有規律網球運動者從事網球運動至少三年，每週至少打網球3天。以「三軸向身體活動量測量器」(RT3 Tri-axial；RT3) 測量假日與非假日身體活動量，且以福樂進階平衡表(Fullerton Advanced Balance scale, FAB scale)測量10個項目之平衡能力。所得資料以描述性統計、皮爾森積差相關及獨立樣本t考驗等統計方法進行分析 。結果顯示網球組老年人每天身體消耗的總熱量為(2277.3 ± 549.8kcal/day)明顯高於對照組的(2073.1 ± 522.3kcal/day) (p＜.05)；網球組老年人之 10個項目平衡能力(總分)顯著優於對照組(p＜.05)。 結果顯示規律從事網球運動男性老年人有較高之身體活動量和有較佳之平衡能力。

The purposes of this study were to compare the difference in physical activity (PA) and balance between the elderly with and without regular playing tennis. There were 40 regular male tennis elderly players (tennis group) and 40 non-regular exercise male elderly (control group) were recruited as the subjects, the average age of total 80 subjects was 65.1 ± 3.5 years old. The regular tennis players had been playing tennis for at least 3 years, and at least 3 days per week. All the subjects were asked to wear the RT3 Tri-axial (RT3) on two separate days (weekday and weekend) for the PA measurement. In addition, the subjects were performed the Fullerton Advanced Balance scale (FAB scale) to determine the balance ability. All the collected data were analyzed by description statistics, t-test, and Pearson Correlation test, and the result as followed. The PA of the tennis group (2277.3± 549.8kcal/day) was significantly higher than that of control group (2073.1 ± 522.3kcal/day) (p＜.05);the balance of tennis group was significantly better than that of control group (p＜.05).
The research result indicated that the male elderly who had engaged in regular tennis have more daily Physical Activity and better balance.
