MSc Physiology Flashcards
Three main factors for endurance performance
- Maximal oxygen uptake V.O2max
- Lactate Threshold
- Effciency
What is VO2max / Maximal oxygen uptake
The oxygen uptake attained during maximal exercise intensity that could not be increased despite further increases in exercise workload, thereby defining the limits of the cardiorespiratory system.
What is Lactate Threshold
Your lactate threshold is the level at which the intensity of exercise causes lactate to accumulate in the blood at a faster rate than it can be removed
What is Efficiency
Oxygen cost to generate a running speed/cycling output
What is Performance VO2
Oxygen consumption sustainability at a given period. Determined by VO2max and Lactate Threshold
What is Performance Velocity
Performance velocity is determined by maximal rates of aerobic energy production and anaerobic capacity and how efficiently the energy being used is converted to movement
What is Endurance exercise performance velocity
Level of aerobic metabolism that can be maintained during a race
What does Maximal Oxygen Uptake represent the integrative ability of the heart to generate
- High Cardiac Output
- Total Body Haemoglobin
- High Muscle blood flow and muscle oxygen extraction
- Ability of lungs to oxygenate blood
VO2max Values in Elite Male and Female
70-80 ml kg-1 min-1
Adaptation for high VO2max scores
- Increased cardiac output (most dominant)
- Increased blood volume
- Increased capillary and mitochondria density
