Four Categories of Total Weekly Amounts of Aerobic Physical Activity Inactive is no activity beyond baseline activities of daily living Low activity is activity beyond baseline but fewer than 150 minutes of moderate-intensity physical activity a week or the equivalent amount (75 minutes)of vigorous-intensity activity Medium activity is 150 minutes to 300 minutes of moderate intensity activity a week(or 75 to 150 minutes of vigorous intensity physical activity a week). In scientific terms, this range is approximately equivalent to 500 to 1,000 metabolic equivalent(MET代谢当量) minutes a week High activity is more than the equivalent of 300 minutes of moderate-intensity physical activity a weekFour Categories of Total Weekly Amounts of Aerobic Physical Activity ▪ Inactive is no activity beyond baseline activities of daily living. ▪ Low activity is activity beyond baseline but fewer than 150 minutes of moderate-intensity physical activity a week or the equivalent amount (75 minutes) of vigorous-intensity activity. ▪ Medium activity is 150 minutes to 300 minutes of moderate￾intensity activity a week (or 75 to 150 minutes of vigorous￾intensity physical activity a week). In scientific terms, this range is approximately equivalent to 500 to 1,000 metabolic equivalent (MET代谢当量) minutes a week. ▪ High activity is more than the equivalent of 300 minutes of moderate-intensity physical activity a week
