2. Protein and amino acid supplements are needed as energy sources for weight lifters.

The use of protein as an energy source is greater for endurance athletes than for those who body build or lift weights.

Explanation:

The main source of energy for our body is glucose. Body store glucose as glycogen on liver and muscle. When blood glucose gets over the body use glycogen reserve to get energy. Glycogen can only provide energy for a very short period of time.

Lipids provide energy to the body for a long time. Lipids are responsible for giving energy for long endurance activity. Proteins are only used for energy when glucose and lipid reserves get exhausted in the body. So endurance athletes need more protein as an energy source than the person who lifts weight.
