Americans should exercise about twice as much as the 2 hours a week they report, researchers said, after analyzing current data on more than 100,000 respondents of all ages. The CDC recommends adults ages 18-64 get about 4 hours of physical activity each week by exercising moderately for 2.5 hours per week and engaging in a vigorous activity for 1 hour and 15 minutes per week. Walking is the most prevalent activity -- about 5% of Americans walk about 53 minutes per week. Basketball was the most popular active sport followed by football, soccer, baseball, volleyball and hockey.Online Time, May 2012 |
