Energy systems Flashcards
Aerobic Respiration
The usual process for releasing energy for your muscles - occurs WITH oxygen.
The equation for aerobic respiration
Glucose + Oxygen =
Energy + CO2 +Water
Anaerobic Respiration
This is when your muscles have to work at a very intense level - occurs WITHOUT oxygen.
The equation for anaerobic respiration
Glucose = Energy + Lactic acid
3 stages involved with anaerobic energy systems
Glycolysis
The Krebs Cycle
The Electron Transport Chain
What is ATP
The ATP molecule is
how your energy is
stored and used in the
body.
How much ATP is produced overall
Up to 38 ATP are
produced across the 3
stages.
V02 max
the maximum volume
of oxygen that can
be consumed by the
working muscles
per minute.
Factors affecting V02 max
Age
Muscle fibres
Training
Genetics
RBC count
Lifestyle
Body composition
Gender
Measurements of energy expenditure
Indirect Calorimetry
Lactate Sampling
VO2 Max
Respiratory Exchange
Ratio (RER)
Lactate accumulation
the increase of lactate as a result of anaerobic activity.
Lactate threshold
the point during exercise at which lactic acid quickly
accumulates in the
blood.
OBLA
the point at which blood
lactate levels go above 4 millimoles per litre.
Factors affecting lactate accumulation
Intensity of exercise
Fitness of performer
VO2 max of performer
Performer’s OBLA
Specialist training methods
Altitude
HIIT
Speed agility Quickness
Plyometrics
The ‘breakdown of fatty acids in order to provide ATP’ is known as what?
Beta oxidation
What is EPOC
- It is the volume of oxygen consumed in recovery above the resting rate
- occurs in order to repay the oxygen debt and begin to break down lactic acid
- occurs in order to resynthesise ATP levels
- occurs in order to resaturate myoglobin
with oxygen
What is lactate sampling
measuring the level of lactate in the blood stream
Why is locate sampling used
It can be taken to understand at what point during exercise/performance OBLA
occurs (4mmol/L). It should be used by performers who exercise anaerobically but
at a submaximal level
How to test V02 max
Carried out on a treadmill or other cardiovascular equipment, it is used to calculate the maximum amount of oxygen that can be consumed per minute
How to measure Indirect calorimetry
measures the consumption of oxygen and production of
Co2 using a mask and metabolic cart. It can be used at rest or during exercise and
would mainly be used by endurance athletes
What is RER
Ratio of carbon dioxide produced compared to oxygen consumed in order to measure a performer’s reaction to
exercise. It should mainly be used by endurance athletes
