摘要

目的：在运动过程中使用视听刺激是一种增强愉悦感的有效策略，这对于持续运动至关重要。根据自我决定理论，自我选择的视听刺激可以提高自主性和内在动机。然而，自我选择的视听刺激的影响仍然没有定论。因此，本研究探讨了自我选择的视听刺激对急性耐力运动中情感反应和前额叶氧合的影响。方法29名身体缺乏运动的个体（年龄= 19.6,SD = 1.4岁，男性3名）在自我选择（SS）、研究者选择（RS）和无视听刺激(C) 3种情况下进行干预。条件是随机和平衡的。参与者锻炼23分钟（3分钟热身+ 20分钟中等强度跑步机）。功能近红外光谱评估背外侧前额皮质（dlPFC）皮质氧合变化。在运动前和运动中测量心理反应（情感效价、觉醒、感知运动和注意力集中）。采用线性混合模型比较条件差异。结果被试的积极情感效价增加（p = 0.02, η = p2 = 0.02），外部注意焦点增加(p <；0.05, ηp2 = 0.16)。右侧dlPFC的氧合血红蛋白（O2Hb）在SS中也较高(p <；0.01, ηp2 = 0.05)。然而，情感效价与O2Hb之间的相关性不显著(右dlPFC: r = 0.21, p = 0.12；左dlPFC: r = - 0.17, p = .19)。结论自选视听刺激可诱导阳性情感效价，增加右侧dlPFC的O2Hb。这些刺激可能激活右前额叶皮层来调节消极的情感效价。未来的研究应该探索调节或调节这些影响的因素，进一步了解增强运动相关的积极情感效价的神经生理过程。

Effects of self-selected audiovisual stimuli on affective responses and cortical oxygenation in the prefrontal cortex during acute endurance exercise: An fNIRS study

Objectives

Using audiovisual stimuli during exercise is an effective strategy to enhance pleasure, which is crucial for sustaining exercise. According to self-determination theory, self-selected audiovisual stimuli may boost autonomy and intrinsic motivation. However, the effects of self-selected audiovisual stimuli remain inconclusive. Thus, this study examines the impact of self-selected audiovisual stimuli on affective responses and prefrontal oxygenation during acute endurance exercise.

Methods

Twenty-nine physically inactive individuals (M_age = 19.6, SD = 1.4 years, 3 males) participated in the intervention with three conditions: self-selected (SS), researcher-selected (RS), and no audiovisual stimuli (control, C). Conditions were randomized and counterbalanced. Participants exercised for 23 min (3 min warm-up + 20 min moderate-intensity treadmill running). Functional near-infrared spectroscopy assessed cortical oxygenation changes in the dorsolateral prefrontal cortex (dlPFC). Psychological responses (affective valence, arousal, perceived exertion, and attentional focus) were measured before and during exercise. Linear mixed models were used to compare condition differences.

Results

Participants reported more positive affective valence (p = .02, η_p² = 0.02) and more external attentional focus (p < .01, η_p² = 0.16) in the SS compared to the RS condition. Oxygenated hemoglobin (O₂Hb) in the right dlPFC was also higher in the SS (p < .01, η_p² = 0.05) compared to the RS condition. However, correlations between affective valence and O₂Hb were not significant (right dlPFC: r = 0.21, p = .12; left dlPFC: r = −0.17, p = .19).

Conclusions

Self-selected audiovisual stimuli appear to induce positive affective valence and increase O₂Hb in the right dlPFC. These stimuli may activate the right prefrontal cortex to regulate negative affective valence. Future research should explore factors that moderate or mediate these effects, providing further insight into the neurophysiological processes that enhance exercise-related positive affective valence.

期刊介绍： The aims of Mental Health and Physical Activity will be: (1) to foster the inter-disciplinary development and understanding of the mental health and physical activity field; (2) to develop research designs and methods to advance our understanding; (3) to promote the publication of high quality research on the effects of physical activity (interventions and a single session) on a wide range of dimensions of mental health and psychological well-being (eg, depression, anxiety and stress responses, mood, cognitive functioning and neurological disorders, such as dementia, self-esteem and related constructs, psychological aspects of quality of life among people with physical and mental illness, sleep, addictive disorders, eating disorders), from both efficacy and effectiveness trials;
