Excersise physiology - energy systems explained, eg lactic acid etc

Describe each of the skill outlines

*ATP-CP (phosphogen) schema

Stored at the myosin cross-bridges is wiped out(p) down to rout out energy for contraction it is employ for short bursts of energy - it is wash up after about 10 seconds.

*Lactic Acid establishment

Carbohydrate is broken down anareobically (without oxygen) to lactic acid. This causes muscular fatigue. The energy released during this division is used to re-synthesize A.T.P. Exercise performed at maximum rates for between superstar and three minutes depending heavily upon the lactic acid system for A.T.P energy.

*Oxygen System

Firstly uses glucose from either muscle tissue or from the colored and secondly breaks down fatty acids. The main fuel is glucose.

What is A.T.P

The ability for muscle contraction which comes from the breakdown of a chemical merge named adenosine tri inorganic orthophosphate (ATP)

Sources of ATP: Protein, Carbohydrates and Fats

How is A.T.P produced in each energy system?

a) A.T.P - C.P

ADP and the phosphate are converted back to A.T.P by the creatine phosphate (CP) when A.T.P is depleted.

b) Lactic Acid

Carbohydrate is broken down anareobically (without oxygen) to lactic acid.

The energy released during this breakdown is used to re-synthesize A.T.P.

c) Oxygen

What is the fuel source for each of the energy systems?

ATP-CP System -

Lactic Acid System - Glycogen

Oxygen System - Glucose, triglycerides

How are each of these fuels replenished?

a) Phosphagen

b) Anaerobic

c) Aerobic

What is the fuel stored for each energy system?

ATP-CP System - myosin cross-bridges

Lactic Acid System - glycogen

Oxygen System -

What is the time frame in which each energy operates?

ATP-CP System - Up to 10 Seconds, Short-duration activites

Lactic Acid System - 1 - 3 Minutes

Oxygen System - Long-duration activities

Explain the Anaerobic Threshold

The intensity of effort at which lactic acid accumulates. Usually...
