Recent evidence identifies a potent role for aerobic exercise to modulate activity of hypothalamic neurons related to appetite; however, these studies have been primarily performed in male rodents. Since females have markedly different neuronal mechanisms regulating food intake, the current study aimed to determine the effects of acute treadmill exercise on hypothalamic neuron populations involved in regulating appetite in female mice. Mature, untrained female mice were exposed to acute sedentary, low (10m/min), moderate (14m/min), and high (18m/min) intensity treadmill exercise in a randomized crossover design. Mice were fasted 10-hours before exercise and food intake was monitored for 48-hours after bouts. Immunohistochemical detection of cFOS was performed 3-hours post-exercise to determine changes in hypothalamic NPY/AgRP, POMC, tyrosine hydroxylase, and SIM1-expressing neuron activity concurrent with changes in food intake. Additionally, stains for pSTAT3tyr705 and pERKthr202/tyr204 were performed to detect exercise-mediated changes in intracellular signaling. Briefly, moderate and high intensity exercise increased 24-hour food intake by 5.9% and 19%, respectively, while low intensity exercise had no effects. Furthermore, increases in NPY/AgRPARC, SIM1PVN, and tyrosine hydroxylase neuron activity were observed 3-hours after high intensity exercise, with no effects on POMCARC neurons. While no effects of exercise on pERKthr202/tyr204 were observed, pSTAT3tyr705 was elevated specifically in NPY/AgRP neurons 3-hours post-exercise. Overall, aerobic exercise increased activity of several appetite-stimulating neuron populations in the hypothalamus of female mice, which may provide insight into previously reported sexual dimorphisms in post-exercise feeding.
