Physical activity is a widely achievable means to a healthier life. Physical activity levels vary by age, education, and income level. At least half of adults in every age, education, and income group were sedentary in 1994. Fewer adults with higher incomes and educations are sedentary. Lower levels of sedentary lifestyle were associated with increased income and, especially, increased education.
Current recommendations focus on a lifestyle approach to increasing physical activity.
Moderate physical activity would include brisk walking, climbing stairs, expending more energy in house and garden activities, and engaging in active recreational pursuits. Previously, recommendations specified guidelines regarding frequency, intensity, and duration of activity. Examples of these activities include fast walking, running, cycling, swimming, or aerobic classes. Recent physical activity recommendations include both the structured and lifestyle approaches to increasing physical activity. Either approach is beneficial for an inactive person, and individual interests and opportunities should determine which is used.
