title: Engagement in muscular strengthening activities is associated with better sleep.
abstract: Few studies have examined whether engagement in muscular strengthening activities is associated with sleep duration, which was the purpose of this study. Data from the population-based 2005-2006 National Health and Nutrition Examination Survey were used, which included an analytic sample of 4386 adults (20-85 yrs). Sleep duration and engagement in muscle strengthening activities was self-reported. After adjustments (including aerobic-based physical activity), those engaging in muscular strength activities, compared to those not engaging in muscular strengthening activities, had an 19% increased odds of meeting sleep guidelines (7-8 h/night) (Odds Ratio = 1.19, 95% Confidence Interval: 1.01-1.38, P = 0.04). Promotion of muscular strengthening activities by clinicians should occur not only for improvements in other aspects of health (e.g., cardiovascular benefits), but also to help facilitate optimal sleep duration.
