The statement that anaerobic and aerobic exercises are important in developing cardiorespiratory fitness is true. The difference between these two types of physical activity is the intensity, interval and types of muscle fibers incorporated. Aerobic exercise as any activity that uses large muscle groups, can be maintained continuously and is rhythmic in nature, while anaerobic exercise is an intense physical activity of very short duration, with contracting muscles and independent of the use of inhaled oxygen as an energy source. However, both of them have different goals and good for our health.
