Final answer:
The ACSM and HHS both recommend at least 150 minutes of moderate-intensity or 75 minutes of vigorous-intensity aerobic exercise weekly, along with muscle-strengthening activities for healthy adults. The HHS provides a range, suggesting additional benefits from exceeding the minimum recommended levels of physical activity.
Step-by-step explanation:
The American College of Sports Medicine (ACSM) recommends that healthy adults aged 18-65 should engage in at least 150 minutes of moderate-intensity aerobic exercise or 75 minutes of vigorous-intensity exercise per week. Additionally, they advise participating in strength-training exercises for all major muscle groups at least two days per week.
In comparison, the Department of Health and Human Services (HHS) provides similar guidelines, recommending 150 to 300 minutes of moderate-intensity, or 75 to 150 minutes of vigorous-intensity aerobic physical activities per week, spread throughout the week. The HHS also advises muscle-strengthening activities on 2 or more days per week.
Differences between the ACSM and HHS recommendations might be minimal as both emphasize regular aerobic exercise and muscle-strengthening exercises. However, the HHS provides a range for aerobic activity (150 to 300 minutes of moderate-intensity or 75 to 150 minutes of vigorous-intensity exercise), suggesting that engaging in physical activity beyond these minimums can yield additional health benefits and assist with weight loss and maintenance.
