      摘要: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±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<.05,d=.89),强度的意向显著低于控制组(F(1, 56)=5.85,p<.05,Partial η2=.10),时间的意向差异也显著低于控制组(F(1, 56)=6.96,p<.05,Partial η2= .11),而两组频率的意向差异不显著(F(1, 56)= 0.73,p>.05,Partial η2=.01)。实验二,56名中学生(男26人,女30人,年龄为13.41±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<.01,d=.74),强度显著低于控制组(F(1, 54)=5.36,p<.05,Partial η2= .09),时间也显著低于控制组(F(1, 54)=4.27,p<.05,Partial η2=.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。

      Abstract: The current study further 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 1, 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 2, 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.
