Exercise-induced activation of ventromedial hypothalamic steroidogenic factor-1 neurons mediates improvements in endurance.

ABSTRACT: Repeated exercise produces robust physiological benefits and is the leading lifestyle intervention for human health. The benefits from exercise training result from the remodeling of skeletomuscular, cardiovascular, metabolic, and endocrine systems. In mice, we find that activation of the central nervous system following exercise is essential for subsequent endurance performance and metabolism benefits. Ventromedial hypothalamic steroidogenic factor-1 (SF1) neurons are activated following exercise, and repeated training results in increased post-exercise SF1 neuron activation. Exercise training increases the intrinsic excitability and density of excitatory synapses on SF1 neurons, suggesting that exercise history is encoded through hypothalamic plasticity. Inhibition of SF1 neuron output b
