    Study Notes

    Physical Activity Guidelines

    • The U.S. Department of Health and Human Services publishes Physical Activity Guidelines for Americans to provide information on the types and amounts of physical activity that provide substantial health benefits.
    • The guidelines aim to provide general-purpose recommendations that broadly support enhanced health and wellbeing.

    Energy Expenditure and Physical Activity

    • Physical Activity Level (PAL) takes into account overall energy expenditure, including exercise, thermic effect of food, and non-exercise related physical activity.
    • For an individual weighing 60 kg (132 lb), their estimated metabolic rate would be around 1,104 kcals, and if they ate a 2,000 kcal diet, they would expend 200 kcals in thermic effects of food.
    • To be considered moderately active, an individual would need to accumulate over 500 kcals of activity outside of exercise behaviors.

    Recommendations for Safe Physical Activity

    • Public health recommendations regarding safe physical activity encompass two distinct aspects of safety:
      • Risk of injuries and other adverse events resulting from the activity
      • Risks associated with the context in which the physical activity takes place
    • Injuries, adverse events, and issues do occur, but the vast majority of musculoskeletal injuries incurred through physical activity do not require medical treatment.

    24-hour Movement Guidelines for Adults

    • Adults should engage in at least 150 minutes of moderate to vigorous intensity aerobic physical activity per week.
    • Perform muscle strengthening activities using major muscle groups at least twice a week.
    • Engage in several hours of light physical activities, including standing.
    • Obtain 7 to 9 hours of good-quality sleep on a regular basis.
    • Limit sedentary time to 8 hours or less, including no more than 3 hours of recreational screen time.

    24-hour Movement Guidelines for Children and Youth

    • Children aged 5-17 should participate in at least 60 minutes per day of moderate to vigorous physical activity.
    • Vigorous physical activities and muscle and bone strengthening activities should each be incorporated at least 3 days per week.
    • Engage in several hours of light physical activities.
    • Obtain 9 to 11 hours of uninterrupted sleep with consistent bed and wake-up times (aged 5-13) or 8 to 10 hours (aged 14-17).
    • Limit recreational screen time to 2 hours per day and avoid sitting for extended periods.

    Physical Activity and Health Risks

    • Exceeding physical activity recommendations is associated with greater health benefits, but also increases the risk of injury.
    • Greater exercise intensity is associated with higher injury risk.
    • Organized sport participation increases the relative risk of musculoskeletal injury, particularly in instances of sport specialization.

    Criticisms of Public Health Recommendations

    • The 10,000 step goal was not set in response to specific evidence of effectiveness relative to health or wellbeing.
    • Pedometers fail to accurately track the intensity of activities and inaccurately estimate caloric expenditure.
    • The use of metabolic equivalents of tasks is conceptually straightforward, but their use within public health recommendations is debated.
    • There is inconsistency in using daily recommendations in children but weekly recommendations for adults.
