The aerobic phase itself improves cardiorespiratory endurance something that is achieved with a long-term.
The first three components listed (cardiorespiratory endurance, muscular endurance, muscle strength) are important if you wish to have a positive impact on body composition. Also, doing them will result in less fat. Why is that important?
enhance their abilities to focus and concentrate;
