This study investigated the acute effect of exercise on sleep outcomes among healthy older women by comparing days with structured exercise versus days without structured exercise during 4 months of exercise training. Participants (n = 51) in this study had wrist-worn actigraphic sleep data available following at least 3 days with structured exercise and 3 days without structured exercise at mid-intervention and at the end of intervention. The exercise intervention was treadmill walking. Multilevel models were used to examine whether structured exercise impacted sleep outcomes during the corresponding night. Overall, 1,362 nights of data were included in the analyses. In unadjusted and adjusted models, bedtimes were significantly earlier on evenings following an acute bout of structured exercise than on evenings without structured exercise. No other sleep parameters differed between exercise and nonexercise days. Understanding the effects of exercise on sleep in this understudied population may help to improve their overall sleep quality.

appropriate sleep quality and quantity is of further importance for athletic populations. Moreover, changes in sleep behavior enforced by training and competition create difficulties for athletes to obtain sufficient sleep to aid performance and recovery. 4 Accordingly, the aim of this brief review is to

Sleep concerns are prevalent among student-athletes and can result in impaired athletic and academic performance. The current study investigated the feasibility and effectiveness of a brief sleep workshop for student-athletes. Athletes (N = 152) completed baseline and follow-up questionnaires (n = 104) after the intervention. Greater than half of the athletes (51%) who attended the workshops and followup reported at least one change in sleep behaviors. Results revealed a significant decrease in sleepiness from baseline to follow-up and an improvement in daytime functioning. Although athletes reported an increase in problematic sleep hygiene behaviors, they recorded significant increases in sleep knowledge from baseline to follow-up, which was maintained at the second follow-up. These longitudinal data provide evidence that a brief psychoeducation sleep workshop for student-athletes is promising for improving sleep knowledge and daily functioning.

Background:

This study examines state and regional disparities in vigorous physical activity levels among US children age 6 to 17 years.

Methods:

The 2003 National Survey of Children’s Health was used to calculate vigorous physical activity (VPA) and no days of vigorous physical activity (NVPA) prevalence by state and geographic region. Logistic and least squares regression were used to analyze geographic disparities.

Results:

Vigorous physical activity levels varied substantially across geographic areas, with the East Southcentral region of the US having the highest NVPA prevalence (13.4%) and the Pacific region the lowest prevalence (9.1%). Children in Georgia and Tennessee had 2.2 to 2.3 times higher odds and children in DC, Oklahoma, Arkansas, Indiana, Kentucky, Kansas, New Jersey, South Carolina, and Washington (adjusted prevalence >13.4%) had 1.8 to 2.0 times higher odds of NVPA than children in California (adjusted prevalence = 8.4%). Adjustment for race/ethnicity, socioeconomic status, social capital, television viewing, sleep behavior, and parental physical activity doubled the magnitude of geographic disparities in vigorous physical activity levels. Area poverty, income inequality, and violent crime rates were independent predictors of VPA and NVPA.

Conclusions:

Although individual and area-level socioeconomic factors are important predictors, substantial geographic disparities remain, with children in several Southern states having particularly high risks of NVPA.

sleep suggests that it should not be difficult to get athletes to improve sleep behavior. However, athletes often obtain well below the general recommendation of 8 hours of sleep per night. 2 – 4 Potentially one of the hardest things to change is the use of electronic devices before bed.

); however, due to competing athletic and academic schedules, student athletes are often expected to train early in the morning, which may impact sleep behaviors ( Venter, 2014 ). Sleep quantity, quality, structure, and consistency are recognized as important aspects of sleep behavior and have implications
