Vigorous Physical Activity By Youth
View as PDF (Best for Printing)

Headline

Regular, vigorous physical activity among high school students increased notably between 2003 and 2005, from 63 percent to 69 percent. (See Figure 1) Increases were evident for males and females, and among whites, blacks, and Hispanics. (See Table 1)

Importance

Regular physical activity has both short- and long-term health benefits. For adolescents, participation in sports, physical education classes, or any other type of regular exercise helps to build and maintain healthy bones and muscles, controls weight, and has positive psychological benefits.¹

Adolescents who exercise also improve their long-term health. Participation in physical activity decreases the risk of developing diabetes, heart disease, and hypertension.² Additionally, people who are active in their youth tend to remain active and physically fit as adults.

The International Consensus Conference on Physical Activity Guidelines for Adolescents recommended that adolescents should be physically active daily and participate in vigorous physical activity three or more times a week for at least twenty minutes.³ This recommendation has been adopted as part of the Healthy People 2010 goals (see below).

Trends

Between 1993 and 2003, the percentage of high school students participating in vigorous physical activity remained fairly steady, ranging between 63 percent and 66 percent. However, in the last two years, total participation rates have significantly increased, rising from 63 percent in 2003 to a high of 69 percent in 2005. Increases were evident for males and females, and among whites, blacks, and Hispanics. (See Table 1)

Differences by Gender

A much higher percentage of adolescent males participate in vigorous physical activity than do their female peers. Within all racial and ethnic subgroups, levels for males are between 13 and 19 percentage points higher than for females. (See Table 1) Differences between males and females are also significant for all grades. (See Figure 2)

Differences by Race and Ethnicity⁴

Non-Hispanic blacks had significantly lower rates of participation than non-Hispanic whites and Hispanics in 2005, with participation rates at 62 percent versus 70 percent and 69 percent, respectively. (See Figure 3)

Differences by Age

As high school students get older, the amount of vigorous exercise they get declines. In 2005, the proportion who got vigorous exercise dropped from 74 percent to 62 percent between ninth and twelfth grade. (See Table 1) The difference was most pronounced among females, who dropped from 68 percent in ninth grade to 52 percent by twelfth grade. (See Figure 2)

National Goals

Through its Healthy People 2010 initiative, the federal government has set a national goal to increase the number of adolescents who engage in vigorous physical activity to 85 percent from a 1999 level of 65 percent. To do this, the Centers for Disease Control and Prevention and the President's Council on Physical Fitness and Sports have urged public and private schools to require daily physical education for all students and to educate students about the benefits of exercise.

⁴ Race/ethnicity estimates from 1999 and later are not directly comparable to earlier years due to federal changes in race definitions. In surveys conducted in 1999 and later, respondents were allowed to select more than one race when selecting their racial category. Estimates presented here only include respondents who selected one category when choosing their race.

Definition

Vigorous physical activity here refers to activities that caused sweating and hard breathing for at least 20 minutes on at least 3 of the 7 days preceding the survey.
