Cardio-respiratory fitness is essential for health and is a marker of the functional status of the cardiovascular, respiratory, and skeletal muscular systems.
Cardio-respiratory fitness is influenced in part by non-modifiable factors such as age and gender. However, the main determinants are lifestyle-related, and in particular, habitual physical activity. One of the best ways to increase and maintain your cardio-respiratory fitness is to meet the recommendation of 150 minutes of moderate- to vigorous-intensity aerobic physical activity per week, such as brisk walking.
