What causes this? Well some physical changes are caused by aging of course. The heart, lungs, muscles, nervous system, and etc. are affected overtime.
Age brings the heart rate and an overall decline in maximum cardiac output. It also affects the amount of blood the heart pumps throughout your body; both of which limit athletic performance. In opposition of when younger athletes exercise, the size of the muscle in the walls of the heart chambers increase. Which the younger athletes have a lower heart rate. In other words, the heart is able to slow down because it is working more efficiently. In older athletes, heart muscle size is not increased by exercise to the same degree.
Aging also leads to a decrease in overall lung capacity and a decline
