科学家发现小鼠的脑电路会增强运动耐力,这表明人类可能存在类似的途径。 Scientists discover a brain circuit in mice that boosts exercise endurance, suggesting similar pathways may exist in humans.

宾夕法尼亚大学的科学家们发现,小鼠中含有SF1神经元的脑电路对通过锻炼来建立耐力至关重要。 Scientists at the University of Pennsylvania have found that a specific brain circuit in mice, involving SF1 neurons in the ventromedial hypothalamus, is critical for building endurance through exercise. 这些神经元在经过定期培训后变得更加活跃并形成更多的连接,被阻塞的神经元防止耐力增益,人工激活的神经元提高性能。 These neurons become more active and form more connections after regular training, with blocked neurons preventing endurance gains and artificially activated ones improving performance. 大脑在调节能源使用和新陈代谢适应方面的作用挑战了一种观念,即行使利益纯粹是物理的。 The brain's role in regulating energy use and metabolic adaptation challenges the idea that exercise benefits are purely physical. 虽然这项研究是针对小鼠进行的,但研究人员认为,人类可能存在类似的机制,有可能为加强健身提供新的途径,特别是针对老年人或有流动问题的人。 While the study was done in mice, researchers believe similar mechanisms may exist in humans, potentially offering new ways to enhance fitness, especially for older adults or those with mobility issues. 这些调查结果于2026年2月12日在Neuron发表。 The findings were published in Neuron on February 12, 2026.
