Describe in Detail

Tony and Larry continue to train for a substantial period. Name 2 training effects for heart and 2 for respiratory system.

Explanation

Two long term training effects of exercise on the heart are:

1) Arterial walls become more elastic which allows greater tolerance of changes in blood pressure.

2) The accumulation of lactic acid is much lower during high-levels activity, due to the circulatory system providing more Oxygen and removing waste products faster.

Two long term training effects on the respiratory system are:

1) This results in larger respiratory volumes, which allows more Oxygen to be diffused into the blood flow.

2) An increase in the number and diameter of capillaries surrounding the alveoli leads to an increase in the efficiency of gaseous exchange.

Both students are very enthusiastic about their training but tend to over train.
