目的：探討互動式遊戲Wii Sports之網球與拳擊遊戲的運動強度差異。方法：受試者為12名無固定運動習慣之健康男性（年齡：24.20±1.48歲），在熟悉實驗器材及環境後，分別進行Wii Sports之網球及拳擊遊戲實驗各30分鐘（兩次實驗至少間隔24小時），實驗過程中，受試者需全程配戴可攜式氣體分析儀(Metamax)及polar心跳錶，以蒐集攝氧量(VO2)、心跳率(HR)、代謝當量(MET)之變化，同時記錄其運動強度自覺量表(RPE)指數，實驗所得資料以相依樣本t-test考驗兩種遊戲之差異顯著情形。結果：拳擊之VO2、HR、MET及RPE皆顯著高於網球遊戲（p<.05, VO2：25.40±1.27 vs. 20.70±1.43毫升／公斤／分，HR：164.50±12.03 vs. 136.80±7.88次／分，METs：7.20±0.35 vs. 5.90±0.38，RPE：17±1.44 vs. 13±1.72）。結論：對無固定運動習慣者而言，Wii Sports網球遊戲為中等強度之運動，而拳擊遊戲則達激烈強度，因此體能較差或不適合從事激烈運動者，需考量Wii Sports拳擊遊戲可能潛藏之風險。

Purpose: The purpose of this study was to assess the differences of exercise intensities between tennis and boxing game in interaction game-Wii Sports. Methods: Twelve sedentary subjects (24.20±1.48 yrs.) without any experiences of playing Wii sports video game were recruited for the study. All subjects were required to play a 30-mins tennis and boxing game of Wii Sports in random order on separate days. The portable cardiopulmonary analysis system, MetaMax 3B and Polar system, were used to collect the physiological responses, included the VO2, HR, MET and RPE. The paired t test was used to examine the differences between tennis and boxing game. Results: The VO2, HR, MET and RPE of boxing game were significantly higher than tennis game (VO2: 25.40±1.27 vs. 20.70±1.43 ml/kg/min, HR: 164.50±12.03 vs. 136.80±7.88 beats/min, MET: 7.20±0.35 vs. 5.90±0.38, and RPE: 17±1.44 vs. 13±1.72; p<.05). Conclusion: To sedentary people, tennis game of Wii Sports is the middle level of exercise intensity. However, boxing game reaches to the hard intensity. Therefore, people who is not able to do hard exercise, needs to think over the potential risk in boxing game of Wii Sports.
