Physical activity is a core component of a healthy lifestyle and covers a range from incidental movement such as commuting to leisure-time physical activity such as sports and exercises that range from moderate-intensity to vigorous-intensity.
Moderate-intensity physical activities refer to those that cause a noticeable increase in breathing rate and heart rate. For instance, individuals who brisk walk at approximately 100 steps per minute should get to an intensity where they would be able to carry on a conversation but do not have enough breath to sing.
Vigorous-intensity physical activities refer to those that cause large increases in breathing rate and heart rate. For instance, one would typically not be able to carry out a conversation while jogging or doing step aerobics but is not out of breath.
