ES - Knowledge of Bioenergetics and Metabolism - Effects of manipulating training variables to target specific energy systems

Question 1

Excess Post Exercise Oxygen Consumption (EPOC)

Answer 1

O2 uptake above resting values to restore the body to the pre-exercise condition

Question 2

Oxygen Deficit

Answer 2

occurs at onset of exercise, when oxygen required for energy is greater as the individuals gradually reaches steady-state

Question 3

Oxygen Debt

Answer 3

when O2 uptake remains above pre-exercise levels for a period of time that varies according to intensity and duration of exercise.

Question 4

How is exercise intensity adjusted to target the ATP-PCr, Glycolytic (fast, slow), and Aerobic energy systems?

Answer 4

as intensity increases and duration decreases, energy systems used transition from Aerobic to Glycolytic, to ATP-PCr

Question 5

How is exercise duration adjusted to target the ATP-PCr, Glycolytic, and Aerobic energy systems?

Answer 5

as exercise duration increases and intensity decreases, the energy system used transitions from ATP-PCr to Glycolytic to Aerobic.

Question 6

Work:rest ratio

Purpose?

Answer 6

Predetermined interval spacing of exercise and rest periods.

Purpose: allow more work to be accomplished at higher exercise intensities w/ the same or less fatigue than during continuous training at same intensity.

Question 7

Interval Training to Train Specific Energy Systems

% max power - energy system stressed - duration - range of W:R

Answer 7

90% to 100% - ATP-PCr - 5 to 10s - 1:12 to 1:20
75% to 90% - Fast glycolysis - 15 to 30s - 1:3 to 1:5
30% to 75% - Fast glycolysis and oxidative - 1 to 3 min. - 1:3 to 1:4
20% to 30% - Oxidative - >3 min. - 1:1 to 1:3

Question 8

How should work rest ratio be adjusted to target different energy systems?

Answer 8

As intensity increases, W:R ratio will be higher depending of the exercise duration.
