Question

Answer the following questions in a minimum of five sentences each. Your initial response to the discussion is due by Wednesday of this week at 11:59 pm. Your two replies to classmates are due by Sunday at 11:59 pm.

1. What are the three energy systems? What are the similarities and differences between the three energy systems. Be sure to include factors such as duration, substrates, advantages, and disadvantages in your answer.

2. Think about your own experience as it relates to these three energy systems. Provide an example of how you have trained one of these energy systems. Do you think that type of training was effective for increasing the efficiency and effectiveness of that specific energy system? Why or why not?

it is for my kinesiology class discussion

Answer 1

The three energy systems are

1. Phosphagen system
2. Anaerobic glycolysis(Lactic acid)
3. Aerobic Glycolysis

PHOSPHAGEN SYSTEM

This system uses the creatine phosphate for production of ATP at higher rates.

It is instantaneously available to the muscles.But due to the limited availability this is a short term source.

The mechanism can produce energy for a time of 30 seconds

It is helpful in the case of intensive muscular exercises of short duration like sprinting.

ANAEROBIC GLYCOLYSIS

Lactic Acid energy system starts to feed the muscle energy if the activity is longer then 30 seconds upto a maximum of 3 minutes. When the glucose is broken down anaerobically, a bi-product called Lactic Acid is also produced which accumulates in the muscle and causes fatigue. This system provides a less power than the phosphagen system but provides more than the aerobic pathway

AEROBIC GLYCOLYSIS

It is a method for long term energy production at a slower rate by the degradation of the carbohydrates.This pathway occurs in the mitochondria of the cell and is used for activities requiring sustained energy production. Aerobic glycolysis has a slow rate of ATP production and is used during longer-duration, low intense activities after the CP and lactic acid stores are depleted.
