Document Summary

Physical activity: ~60-70% of the population is inactive: 85% of the population in north america are considered inactive enough not to improve physiology . Reduces stress, eliminate smoking, living and working in encouraging environments, optimal body composition) Research that has been done about benefits of physical activity. Leisure time physical activity level and hazard ratios for mortality and gains in life expectancy after age 40. Exponential curve as you increase your physical activity, the years of life you get to experience increases exponentially. Life gained can be up to 4 or 5 years longer by just doing activity. Met= 3. 5 mlso2 x kg (body weight) Met= 3. 5 mlso2 x 80 kg = 280 mlso2. Work at 2lo2 = 7. 14 mets x 4 hr/wk: met = oxygen consumption at rest. Years of life expectancy lost after age 40 in relation to body mass index. Looking at: activity levels (more than 7. 5 met hr/wk) 3 different activity levels: body composition (bmi)
