According to the 2018 Physical Activity Guidelines for Americans, Arnold's weekly workout plan of walking for 30 minutes a day, 5 days a week meets the minimum recommendation.
According to the 2018 Physical Activity Guidelines for Americans, the minimum recommendation for adults is to engage in at least 150 minutes of moderate-intensity aerobic activity or 75 minutes of vigorous-intensity aerobic activity per week. In addition to aerobic activity, it is also recommended to engage in strength training exercises at least twice a week.
Looking at Arnold's weekly workout plans:
- Golfing for 2 hours every Sunday: It is not specified whether golfing is done at a moderate or vigorous intensity. Additionally, it is important to engage in aerobic activity throughout the week, not just on one day. Therefore, this plan does not meet the minimum recommendation.
- Biking for 45 minutes a day, 3 days a week: Biking for 45 minutes a day counts as moderate-intensity aerobic activity. Doing this for 3 days a week adds up to a total of 2 hours and 15 minutes, meeting the minimum recommendation. However, strength training is not mentioned.
- Running for 15 minutes a day, 6 days a week: Running for 15 minutes a day adds up to a total of 1 hour and 30 minutes, meeting the minimum recommendation for moderate-intensity aerobic activity. However, strength training is not mentioned.
- Walking for 30 minutes a day, 5 days a week: Walking for 30 minutes a day adds up to a total of 2 hours and 30 minutes, meeting the minimum recommendation for moderate-intensity aerobic activity. However, strength training is not mentioned.
Based on the given options, the plan that meets the minimum recommendation is:
- Biking for 45 minutes a day, 3 days a week.
To determine if Arnold's weekly workout plans meet the minimum recommendation of the 2018 Physical Activity Guidelines for Americans, we need to look at the guidelines themselves. According to these guidelines, adults should aim for at least 150 minutes of moderate-intensity aerobic activity per week or 75 minutes of vigorous-intensity aerobic activity per week, along with muscle-strengthening activities twice a week.
Let's evaluate each of Arnold's weekly workout plans:
1. Golfing for 2 hours every Sunday: Although golf can provide some physical activity, it is not considered moderate or vigorous intensity unless the golfer walks the course without using a cart. Therefore, this plan alone may not meet the minimum recommendation.
2. Biking for 45 minutes a day, 3 days a week: Biking for 45 minutes a day at a moderate intensity for 3 days a week adds up to a total of 135 minutes. Since this meets the threshold of 150 minutes of moderate-intensity aerobic activity per week, this plan meets the minimum recommendation.
3. Running for 15 minutes a day, 6 days a week: Running for 15 minutes a day at a moderate intensity for 6 days a week adds up to a total of 90 minutes. While this falls short of the 150-minute recommendation, it can still be beneficial for cardiovascular health.
4. Walking for 30 minutes a day, 5 days a week: Walking for 30 minutes a day at a moderate intensity for 5 days a week adds up to a total of 150 minutes. Therefore, this plan meets the minimum recommendation.
Based on the 2018 Physical Activity Guidelines for Americans, Arnold's weekly workout plan of biking for 45 minutes a day, 3 days a week, and walking for 30 minutes a day, 5 days a week both meet the minimum recommendation.
