Volition is described as a psychological construct with great emphasis on the sense of agency. During volitional behavior, an individual always presents a volitional quality, an intrapersonal trait for dealing with adverse circumstances, which determines the individual’s persistence of action toward their intentions or goals. Elite athletes are a group of experts with superior volitional quality and, thereby, could be regarded as the natural subject pool to investigate this mental trait. The purpose of this study was to examine brain morphometric characteristics associated with volitional quality by using magnetic resonance imaging (MRI) and the Scale of Volitional Quality. We recruited 16 national-level athletes engaged in short track speed skating and 18 healthy controls matched with age and gender. A comparison of a parcel-wise brain anatomical characteristics of the healthy controls with those of the elite athletes revealed three regions with significantly increased cortical thickness in the athlete group. These regions included the left precuneus, the left inferior parietal lobe, and the right superior frontal lobe, which are the core brain regions involved in the sense of agency. The mean cortical thickness of the left inferior parietal lobe was significantly correlated with the independence of volitional quality (a mental trait that characterizes one’s intendency to control his/her own behavior and make decisions by applying internal standards and/or objective criteria). These findings suggest that sports training is an ideal model for better understanding the neural mechanisms of volitional behavior in the human brain.

“没有痛苦就没有收获”:一项关于优秀运动员意志品质的包裹式脑形态计量学研究的证据。

意志被描述为一种心理建构,非常强调代理意识。在自愿行为期间,个人始终表现出自愿素质,这是应对不利情况的人格特质,它决定了个人对自己的意图或目标的坚持性。优秀运动员是一群具有较高意志品质的专家,因此可以被视为研究这种精神特征的自然对象库。这项研究的目的是通过使用磁共振成像(MRI)和自愿质量量表来检查与自愿质量相关的大脑形态特征。我们招募了16名参加短道速滑比赛的国家级运动员和18名与年龄和性别相匹配的健康对照。将健康对照组与精英运动员的包裹脑部解剖学特征进行比较,发现在运动员组中三个区域的皮质厚度明显增加。这些区域包括左前突,左下顶叶和右上额叶,这是参与感觉的核心大脑区域。左下顶叶的平均皮层厚度与意志质量的独立性(一种心理特征,表征一个人意图控制自己的行为并通过应用内在标准和/或客观标准做出决定)密切相关。这些发现表明,运动训练是理想的模型,可以更好地理解人脑中自愿行为的神经机制。
