Sleep quality improved following a single session of moderate-intensity aerobic exercise in older women: Results from a pilot study.

ABSTRACT:

Background

Poor sleep quality is associated with adverse effects on health outcomes. It is not clear whether exercise can improve sleep quality and whether intensity of exercise affects any of the effects.

Methods

Fifteen healthy, non-obese (body mass index = 24.4 ± 2.1 kg/m², mean ± SD), sedentary (<20 min of exercise on no more than 3 times/week) older women (66.1 ± 3.9 years) volunteered for the study. Peak oxygen consumption (VO_2peak) was evaluated using a graded exercise test on a treadmill with a metabolic cart. Following a 7-day baseline period, each participant completed two exercise sessions (separated by 1 week) with equal caloric expenditure, but at different intensities (60% and 45% VO_2peak, sequence randomized) between 9:00 and 1
