对久坐不动的老年人的干预研究表明，在老年开始体育锻炼对大脑结构有积极影响。尽管这表明，与非运动员相比，终身运动训练的老年运动员在某些大脑区域的灰质体积（GMV）更大，但文献中的证据很少。此外，更大的GMV是否与生活中的训练强度或训练时间有关尚不清楚。为了解决文献中的这些空白，我们比较了24名老年运动员（平均年龄71.4岁，开始运动训练时年龄31.2岁，持续运动训练，40.0岁，目前训练时间7.9小时/周）和24名年龄匹配的非运动员（平均年龄71.0岁）的脑区域GMV。对运动员的运动训练时间和当前训练时间进行评估。对两组人的身体活动强度以及认知和运动表现进行了评估。尽管在认知和运动表现方面没有发现组间差异，但运动员报告的身体活动强度高于非运动员。全脑结构分析显示，运动员的几个脑区GMV明显较大。值得注意的是，运动员楔前叶GMV与运动训练开始时间和训练时间呈正相关，与当前训练时间呈负相关。我们的研究结果表明，早期开始和持续的运动训练可以预测老年时楔前叶的结构维持。我们的研究结果还表明，老年人过度的训练时间可能会对楔前叶的GMV产生负面影响；从而描述楔前叶与老年运动员终身运动训练的关系。
Intervention studies on sedentary older adults have demonstrated that commencing physical exercise at an older age has a positive effect on brain structure. Although this suggests that older athletes with lifelong sports training have larger gray matter volume (GMV) in some brain regions compared to age-matched non-athletes, evidence in the literature is scarce. Moreover, it remains unclear whether a larger GMV is associated with training intensity or period of training in life. To address these gaps in the literature, we compared regional brain GMV between 24 older athletes (mean age, 71.4 years; age at the commencement of sports training, 31.2 years, continuous sports training, 40.0 years; current training time, 7.9 h/week) and 24 age-matched non-athletes (mean age, 71.0 years). The period of sports training and the current training time of the athletes were assessed. Both groups were evaluated for physical activity intensity as well as cognitive and motor performance. Although no group differences were noted in cognitive and motor performance, athletes reported higher physical activity intensity than non-athletes. Whole-brain structural analysis revealed a significantly larger GMV in several brain regions in athletes. Notably, the GMV of the precuneus in athletes was positively correlated with earlier commencement of sports training and training duration but was negatively correlated with current training time. Our findings demonstrate that early-commenced and continued sports training predicts structural maintenance of the precuneus in old age. Our results also suggest that excessive training time in old age may have a negative impact on the GMV of the precuneus; thereby delineating how the precuneus is associated with lifelong sports training in older athletes.
