3. 1. Know the major conclusions of the U.S. Surgeon General's report on Physical Activity and Health.*
People of all ages, both male and female, benefit from regular physical activity. Significant health benefits can be obtained by including a moderate amount of physical activity on most, if not all, days of the week. Through a modest increase in daily activity, most Americans can improve their health and quality of life. Additional health benefits can be gained through greater amounts of physical activity. People who can maintain a regular regimen of activity that is of longer duration or of more vigorous intensity are likely to derive greater benefit. Physical activity reduces the risk of premature mortality in general, and of coronary heart dis- ease, hypertension, colon cancer, and diabetes mellitus in particular. Physical activity also im- proves mental health and is important for the health of muscles, bones, and joints. Morethan60percentofAmericanadultsarenot regularly physically active. In fact, 25 percent of all adults are not active at all. Nearly half of American youths 12-21 years of age are not vigorously active on a regular basis. More- over, physical activity declines dramatically dur- ing adolescence. Daily enrollment in physical education classes has declined among high school students from 42 percent in 1991 to 25 percent in 1995. Research on understanding and promoting physi- cal activity is at an early stage, but some interven- tions to promote physical activity through schools, worksites, and health care settings have been evaluated and found to be successful.

Some health benefits occur greatest with low to moderate levels, some health benefits are achieved at high levels of physical activity, and some increase as physical activity increases.

correlation coefficient (r)
expresses relationship between two variables. Correlations range from -1.0 to +1.0. negative correlations means as one variable increase the other decreases or vice versa. Positive correlation means as one variable increases the other increases or vice versa. The closer the correlation is to 1.0 the better the relationship.
