Answer: In order to compensate for the low partial pressure of oxygen at altitude, the human body undergoes a number of physiological changes. A vital component in this process is the increase in the concentration of circulating haemoglobin. The role of HIF‐1α, erythropoietin and red blood cells in this acclimatisation process is described, together with the fall in plasma volume that increases the concentration of haemoglobin in the early stages of hypoxic exposure.
Explanation:
Builds healthy habits – No one expects to eat three cheeseburgers and fries and then go out and set a personal record at a track meet. Coaches encourage athletes to eat properly before and after races. You perform better and feel better when you have proper nutrition during training. A healthy diet allows you to perform to the best of your abilities, so when you are running track you tend to have a more healthy diet.
Promotes teamwork – Track is an individual as well as team sport. How you perform affects the team, especially in situations such as relay races. All four members are equally important in the race. Each plays a role in the team’s efforts to win. If even one runner does not perform at his best, the whole team may suffer or have to compensate to make up for his weakness.
In addition to this team bond at track meets, friendships are formed during practices. Runners are expected to train daily and have to endure workouts together. This forms bonds that help make the team stronger.

<h3>The effects of aging on immune system</h3>
Immune system is the major system of the body that protects the body against invading disease causing microorganisms. It is made up of,
- proteins (antibodies) and
As an individual advances in age, the efficiency of the immune system, which is it's ability to fight diseases, would reduce.
This is because the production of white blood cells, antibodies and chemicals are equally reduced.
Therefore, as people progress into old age, their disease-fighting immune systems become reduced.
