Oxytocin secretion is related to measures of energy homeostasis in young amenorrheic athletes.

ABSTRACT:

Context

Oxytocin has been implicated in the modulation of energy metabolism in animals. Oxytocin knockout mice develop obesity without a change in food intake, suggesting that a lack of oxytocin may reduce metabolic rate. Furthermore, administration of oxytocin centrally reduces food intake in rats, an effect reversed by an oxytocin antagonist, implying that oxytocin may regulate appetite and energy intake. We have previously demonstrated that young female athletes (in a higher energy expenditure state than nonathletes) have low nocturnal oxytocin compared with nonathletes. Whether oxytocin is associated with measures of energy homeostasis in athletes is unknown.

Objective

We hypothesized that oxytocin, a signal for energy availability, would be associated with other measure
