A single bout of physical activity can benefit one's psychological state, increasing positive affect. Individual differences in these feelings are known to correlate with mental health; however, individual differences in response to physical activity are unclear. This study aimed to quantitatively evaluate individual differences in affect in response to acute physical activities. Quantifying those individual differences implicitly assumed in previous studies would facilitate understanding the relationship between physical activity adherence and mental health.
The dataset comprised valence (pleasant-unpleasant) and arousal (active-inactive) measurements taken before and after two types of physical activities (running and badminton) with a crossover design. Valence and arousal were analyzed using a mixed model. Then, the intraclass correlation coefficients (ICCs) for valence and arousal, which are the ratio of the variance components of individual differences and the sum of total variance components, were calculated. Information processing in cognitive functions was also analyzed and compared variance components among valence, arousal, and information processing to comprehensively evaluate individual differences in valence and arousal in response to physical activity.
The results showed that individual differences in valence and arousal in response to physical activity were significant variance components, whereas the variance component in information processing was not significant. The ICCs for valence, arousal, and information processing were 0.603 (95% confidence interval [95%CI]: 0.430-0.769), 0.349 (95%CI: 0.202-0.512), and 0.171 (95% CI: 0.164-0.217), respectively, demonstrating that the ICC for valence is significantly more pronounced than that for information processing. These findings indicate that the effects of physical activity on affect vary among individuals, particularly regarding changes in valence. Considering individual differences is essential when tailoring physical activity treatments for health.
单次体育活动可有益于一个人的心理状态，增加积极情绪。已知这些感受中的个体差异与心理健康相关；然而，对体育活动反应的个体差异尚不清楚。本研究旨在定量评估对急性体育活动反应中情绪的个体差异。量化先前研究中隐含的那些个体差异将有助于理解体育活动坚持性与心理健康之间的关系。
数据集包括采用交叉设计在两种体育活动（跑步和羽毛球）前后进行的效价（愉快 - 不愉快）和唤醒度（活跃 - 不活跃）测量。使用混合模型分析效价和唤醒度。然后，计算效价和唤醒度的组内相关系数（ICC），其为个体差异方差成分与总方差成分之和的比率。还分析了认知功能中的信息处理，并比较了效价、唤醒度和信息处理之间的方差成分，以全面评估对体育活动反应中效价和唤醒度的个体差异。
结果表明，对体育活动反应中效价和唤醒度的个体差异是显著的方差成分，而信息处理中的方差成分不显著。效价、唤醒度和信息处理的ICC分别为0.603（95%置信区间[95%CI]：0.430 - 0.769）、0.349（95%CI：0.202 - 0.512）和0.171（95%CI：0.164 - 0.217），表明效价的ICC明显高于信息处理的ICC。这些发现表明体育活动对情绪的影响因人而异，特别是在效价变化方面。在为健康量身定制体育活动治疗方案时，考虑个体差异至关重要。
