The 1990 national goal for regular vigorous physical activity is unlikely to be met. While occasional vigorous activity increased, regular participation among adults 25-64 remained low, hindering cardiovascular health improvements.

Area of Science:

Public Health
Exercise Science
Behavioral Science

Background:

National health objectives aim for increased adult physical activity.
Assessing progress towards the 1990 goal of 60% regular vigorous physical activity for adults aged 18-64 is crucial.

Purpose of the Study:

To evaluate American adults' progress toward the 1990 vigorous physical activity goal.
To compare physical activity levels between 1981 and 1984.

Main Methods:

Analysis of two national databases: time diaries (1981) and Simmons Market Research Bureau survey (1984).
Comparison of participation in moderate-to-vigorous activities (e.g., sports, jogging, cycling) among adults aged 25-64.
Adjustment for social desirability bias in survey responses.

Main Results:

No significant change in the number of non-participants in analyzed vigorous activities between 1981 and 1984.
An increase in occasional participation in vigorous physical activity was observed.
Regular participation (≥3 days/week) did not significantly increase; less than 20% of adults 25-64 were regularly active in 1984.

Conclusions:

Adults are showing increased adoption of vigorous activity, but not at a regular enough frequency for substantial cardiovascular benefits.
The 1990 national health objective for regular vigorous physical activity is unlikely to be achieved based on 1984 data.
Further research is needed on the 18-24 age group to fully assess national activity trends.
