本研究主要是探討平常接受不同強度的運動訓練，是否會造成運動者和非運動員於最大運動強度中之最大耗氧量、最大換氣量、最大呼吸次數、最大肺潮氣量、最大心跳數和呼吸交換率的差異。研究中計有15位男性受測者參加，分別為高強度運動組5位(21.1正負1.3yr)，低強度運動組5位(27.95正負2.5yr)和控制組5位(29.58正負3.8yr)。所有受測者於實驗前須測量身高與體重，再以跑步機進行Max VO2的測試。實驗過程中以坡度提高來增加運動強度，但速度不變，直到受測者無法繼續跑步為止。所得結果以單因子變異數分析各組間的數值變化，如有顯著不同則以薛費氏法做事後比較。結果發現如下:1.高強度運動組和低強度運動組之最大耗氧量、最大換氣量、最大肺潮氣量和最大心跳數明顯優於控制組，但最大呼吸次數和呼吸交換率卻比控制組明顯降低。 2.高強度運動組和低強度運動組間並沒有顯著差異。3.從各組的比較結果可以確定，運動並不需過份強調運動強度，只要先培養興趣，以漸進方式增加運動強度，便能提高最大耗氧量和改善心肺功能。 The major goal was to investigateite the effects of Strenuous exercises on the values of Max VO2, Max Ve, Max BR,Max TV, Max HR and R in the male subjects of Wdl-Trained Group (WTG, 21.lt1.3 yr), Lightly Trained Group (LTG, 27.95t2.5 yr) md C Group (CG,29.58t3.8 yr). AII of them were prescribed to perform a series of constant-speed wns up severel hills on a treadmill, each h hill progressively steeper than the next. Once the subjects reached the stmtuous exercise level and were too exhaustive to run any more,their Max VO2 Values were measured. The One-Way ANOVA and Scheffe method were used to analyze the variation between each groups. The results have shown that the values of Max VO2, Max Ve, Max TV, and Max HR during the strenuous exercise were much greater for both the VrTG and LTG than those for the CG, whereas the Max BR as well as R were lower in the WTG and LTG. There was no significant difference between the two trained groups. Coumquently, in terms of exercise, the basic concern is not the strength of exercise but to enjoy it and progressively increase the exercise intensity, then the oxygen cotonsugumpbof` value and cardiopulmoouy ftmction could be obviously improved.
