Energy Systems

Question 1

ATP-CP System

Answer 1

Provides immediate energy for short bursts of intense activity

Question 2

Anaerobic Glycolosis System

Answer 2

Supplies energy for high-intensity activities lasting up to 30-75 secs

Question 3

Aerobic System

Answer 3

Produces energy for sustained, lower-intensity activities. Lasts from 90secs and longer

Question 4

Energy System Overview

Answer 4

ATP-CP: Maximal Intensity, Duration= 0-20s, rate = very high, yield = very low

Anaerobic: Very High Intensity, Duration = 30-75s, rate = high, yield = low

Aerobic: SUb-Maximal Intensity, Duration = 90s+, Rate = very low, Yield = very high

Question 5

Oxygen Deficit

Answer 5

occurs when oxygen supply lags behind oxygen demands – typically at the start of exercise and when exercise intensities rapidly increase (mainly anaerobic energy systems).

Question 6

Oxygen Debt

Answer 6

also known as EPOC (Excess Post – exercise Oxygen Consumption) occurs during recovery whilst oxygen levels remain above resting (largely aerobic energy system).

Question 7

Steady State

Answer 7

occurs when oxygen supply meets oxygen demand (largely aerobic energy system).
