Document Summary
Physical activity refers to any movement of skeletal muscles that requires energy. Exercise specifically refers to physical activities that are planned, repetitive, and intended to improve physical fitness. Moderate-intensity: aerobic activity that increases heart rate and breathing (5-6 on rpe scale, brisk walking, dancing, swimming, cycling (level terrain) Vigorous-intensity: aerobic activity that greatly increases heart rate and breathing (7-8 on rpe scale, jogging, tennis, swimming (continuous laps), cycling uphill. Muscle-strengthening: activity that increases skeletal muscle strength, power, endurance, and mass, strength training, resistance training, muscle strength, and endurance exercises. Ways to determine intensity: percentage of age-predicted maximum heart rate, rate of perceived exertion scale (rpe) Reduce the number of adults engaging in no leisure physical activity by 10% Increase the number of adults who engage in aerobic physical activity of moderate and vigorous intensity. Increase the number of adults who perform muscular strengthening activities. Start by assessing your current level of fitness.
