在考查自我损耗对中学生身体活动意向的影响后,进一步考查对身体活动的影响。实验一,58名中学生（男31人,女27人,平均年龄为13.28岁±0.45岁）完成白熊任务,随后测量身体活动意向,结果显示损耗组的身体活动运动量的意向显著低于控制组（t=-3.34,df=56,p〈0.05,d=0.89）,强度的意向显著低于控制组（F（1,56）=5.85,p〈0.05,Partialη2=0.10）,时间的意向差异也显著低于控制组（F（1,56）=6.96,p〈0.05,Partialη2=0.11）,而2组频率的意向差异不显著（F（1,56）=0.73,p〉0.05,Partialη2=0.01）。实验二,56名中学生（男26人,女30人,年龄为13.41岁±0.50岁）进行数学测验,随后测量身体活动行为,损耗组的身体活动的运动量显著低于控制组（t=-2.27,df=54,p〈0.01,d=0.74）,强度显著低于控制组（F（1,54）=5.36,p〈0.05,Partialη2=0.09）,时间也显著低于控制组（F（1,54）=4.27,p〈0.05,Partialη2=0.07）。结论：自我损耗影响中学生身体活动的意向,具体表现为运动量下降,强度不足与时间缩短;自我损耗影响中学生身体活动行为,具体表现为运动量下降,强度不足与时间缩短。
在攷查自我損耗對中學生身體活動意嚮的影響後,進一步攷查對身體活動的影響。實驗一,58名中學生（男31人,女27人,平均年齡為13.28歲±0.45歲）完成白熊任務,隨後測量身體活動意嚮,結果顯示損耗組的身體活動運動量的意嚮顯著低于控製組（t=-3.34,df=56,p〈0.05,d=0.89）,彊度的意嚮顯著低于控製組（F（1,56）=5.85,p〈0.05,Partialη2=0.10）,時間的意嚮差異也顯著低于控製組（F（1,56）=6.96,p〈0.05,Partialη2=0.11）,而2組頻率的意嚮差異不顯著（F（1,56）=0.73,p〉0.05,Partialη2=0.01）。實驗二,56名中學生（男26人,女30人,年齡為13.41歲±0.50歲）進行數學測驗,隨後測量身體活動行為,損耗組的身體活動的運動量顯著低于控製組（t=-2.27,df=54,p〈0.01,d=0.74）,彊度顯著低于控製組（F（1,54）=5.36,p〈0.05,Partialη2=0.09）,時間也顯著低于控製組（F（1,54）=4.27,p〈0.05,Partialη2=0.07）。結論：自我損耗影響中學生身體活動的意嚮,具體錶現為運動量下降,彊度不足與時間縮短;自我損耗影響中學生身體活動行為,具體錶現為運動量下降,彊度不足與時間縮短。

The current study furtherly examined the effect of ego depletion on the middle school students＇ physical activity after detecting the effect of ego depletion on the intention of physical activity.In experiment one,58 participants（31 males and 27 females,13.28 ± 0.45 yrs） completed the White Bear Task and then their intention of physical activity was measured.Results showed that the intention of physical activity volume of ego depletion group was significantly different from that of control group（t =-3.34,df = 56,P 0.05,d = 0.89）,the strength of intention of the ego depletion group was significantly lower than that of control group（F（1,56）= 5.85,P 0.05,Partial η2= 0.10）,the time of intention of the depletion group was significantly shorter than that of control group（F（1,56）= 6.96,P 0.05,Partial η2= 0.11）,and there was no difference in the frequency of intention between the two groups（F（1,56）= 0.73,P 0.05,Partial η2= 0.01）.In experiment two,56 participants（26 males and 30 females,13.41 ± 0.50 yrs） finished the math tests and their physical activity was measured.Results showed that the difference of physical activity was significant between the two groups（t =-2.27,df = 54,P 0.01,d = 0.74）,the strength of physical activity of the depletion group was significantly lower than that of the control group（F（1,54）= 5.36,P 0.05,Partial η2= 0.09）,the time of intention of the depletion group was significantly lower than the control group（F（1,54）= 4.27,P 0.05,Partial η2= 0.07）.Conclusion：Ego depletion affects the intention of middle school students＇ physical activity,showing lower intention of physical activity volume,strength and time.Ego depletion affects the middle school students＇ physical activity,showing less volume,lower strength and shorter time of physical activity.
