摘要
本研究基于锻炼等级假说,探讨体育锻炼对个体身体自尊的影响。具体内容为测量个体的客观锻炼等级水平,然后进行主观锻炼等级干预,测量其外显和内隐身体自尊的成绩。采用2*2组间的实验设计,对80名男性非体育训练专业大学生(年龄21±1.49岁)进行了研究。将80名大学生根据体育锻炼等级量表分为客观锻炼等级高和低两组,在随机给予这两组大学生体育锻炼等级高或低的主观干预。最后得到客观锻炼等级高且主观锻炼等级高;客观锻炼等级高且主观锻炼等级低;客观锻炼等级低且主观锻炼等级高;客观锻炼等级低且主观锻炼等级低,共四组。然后进行外显和内隐身体自尊测量。结果发现:(1)客观锻炼等级在外显身体自尊上主效应显著(F=82.31,p<0.05,η~2=0.52),客观锻炼等级越高,外显身体自尊越好;主观锻炼等级在外显身体自尊上主效应不显著(F=3.42,p>0.05,η~2=0.04)。(2)客观锻炼等级在评价性内隐身体自尊上主效应显著(F=28.24,p<0.05,η~2=0.27),客观锻炼等级越高,评价性内隐身体自尊越好;主观锻炼等级在评价性内隐身体自尊上主效应显著(F=23.61,p<0.05,η~2=0.24),主观锻炼等级越高,评价性内隐身体自尊IAT成绩越好。(3)主、客观锻炼等级在评价性内隐自尊上交互作用显著(F=8.30,p<=0.05,η~2=0.10),在客观锻炼等级高时,主观锻炼等级高低差异显著;在客观锻炼等级低时,主观锻炼等级高低差异不显著。(4)客观锻炼等级在情感性内隐身体自尊上主效应显著(F=8.24,p<=0.05,η~2=0.10),客观锻炼等级越高,情感性内隐身体自尊越好;主观锻炼等级在情感性内隐身体自尊上主效应不显著(F=1.84,p>0.05,η~2=0.24)。因此,体育锻炼的主观等级越高,个体的评价性内隐身体自尊越好。
This study was designed based on the research of exercise level hypothesis,to discuss the effects of physical exercise on physical self-esteem.It mainly discussed that after figuring out their own exercise level and doing subjective exercise level,then measure their scores of body outer explicit and implicit self-esteem.In this study, the experiment was studied on a 2*2 groups for 80 non-sports male(age 21±1.49 years).80 university students were divided into high and low groups based on objective physical exercise level,and then the two group were randomly assigned for a high or low level of subjective intervention.Finally,we got four groups:the high level of training objectively and the high level of training subjectively;the low level of training objectively and the low level of training subjectively;the low level of training objectively and the high level of training subjectively;the low level of training objectively and the low level of training subjectively.Then measure the body explicit and implicit self-esteem.(1)there was significant difference on the main effect of objective exercise on physical self-esteem level of the outer(F=82.31, p<0.05, η~2=0.52),the higher level of objective exercise, the higher explicit physical self-esteem scale score.there was no significant difference on the main effect of subjective exercise on physical self-esteem level of the outer(F=3.42, p>0.05, η~2=0.04).(2)there was significant difference on the main effect of objective exercise on physical self-esteem level of the inner(F=28.24, p<0.05, η~2=0.27),the higher level of objective exercise,the better IAT results of inner physical self-esteem. And there was also significant difference on the main effect of subjective exercise on physical self-esteem level of the inner(F=23.61, p<0.05, η~2=0.24),the higher level of subjective exercise,the better IAT results of inner physical self-esteem.(3)the subjective and objective level of implicit self-esteem exercise has significant difference on interaction effect(F=8.30, p<=0.05, η~2=0.10),when the level of objective training is high,the subjective exercise level will have significant differences;and when the level of objective training is low,there will be no significant differences between them.(4)The level of objective physical exercise has significant differences on the main effect of emotional self-esteem(F=8.24, p<=0.05, η~2=0.10),the higher level of objective exercise,the higher IAT score for the emotional body esteem. But the level of subjective physical exercise has no significant differences on the main effect of emotional self-esteem(F=1.84, p>0.05, η~2=0.24).Thus, the higher level of subjective exercise, the better results of inner physical self-esteem.
