【摘要】 为探讨体育锻炼量与初中生欺凌行为的因果关系，揭示锻炼改善欺凌行为的剂量效应。方法：采用2(时间：前测、后测)×3(锻炼量：对照组、低剂量、中剂量)混合设计。对照组仅参与常规校园体育活动；低剂量组进行12周中等强度足球训练(每周2次×45分钟)；中剂量组训练方案为每周4次×60分钟。欺凌态度采用单类内隐联想测验(SC-IAT)评估，欺凌行为使用纪艳婷等编制《中学生校园欺凌问卷》测量，并得出相应结果和结论。更多还原

【Abstract】 Objective:To investigate the causal relationship between physical activity volume and bullying behaviors in junior high school students,and to elucidate the dose-response effect of exercise on bullying reduction.Methods:A 2 (Time:pre-test,post-test) × 3 (Exercise dose:control,low-dose,moderate-dose) mixed-design ANOVA was employed (Time as within-subject factor,Exercise dose as between-subject factor).The control group participated only in regular school physical activities;the low-dose group completed 12-week moderate-intensity football training (2 sessions/week × 45 min);the moderate-dose group underwent training at 4 sessions/week × 60 min.Bullying attitudes were assessed using the Single Category Implicit Association Test (SC-IAT),and bullying behaviors were measured via the Middle School Bullying Questionnaire developed by Ji Yanting et al,and draw corresponding results and conclusions.更多还原
