Anaerobic Metabolism
The cellular location of anaerobic metabolism in the muscle cell
What is the sarcoplasm?
The cellular location of aerobic metabolism in the muscle cell
What is the mitochondria?
The largest contributor to total/daily energy expenditure
What is the BMR/RMR?
Glycogen depletion may negatively impact sarcolemma excitability and release of this ion from the sarcoplasmic reticulum
What is calcium?
This term refers to low blood glucose levels
The system which has the fastest rate of ATP production
What is the ATP-PCr System?
The process of fat breakdown in the adipose tissue
What is lipolysis?
The increased rate of oxygen intake and energy expenditure that occurs after exercise
What is excess post-exercise oxygen consumption (EPOC)?
This refers to the intensity of exercise at which there is an abrupt increase in blood lactate levels
What is lactate threshold?
Increases in mitochondrial number and size can be attributed to this type of training
What is aerobic?
This is the body's preferred energy source
What are carbohydrates (glucose)?
The point of intensity at which there is a shift from fats to carbohydrates as a primary fuel source
What is the crossover point?
The method by which metabolic rate is estimated from oxygen consumption and carbon dioxide production
what is indirect calorimetry?
An intracellular buffer that neutralizes cell pH
What is carnosine?
An amino acid supplement that increases buffering capacity with the muscle
What is beta alanine?
When oxygen is insufficient, pyruvate is converted into this
What is lactic acid/lactate?
The process by which fatty acids are made in acetyl CoA
What is beta oxidation?
This value on the metabolic cart represents the relative contribution of fat or carbohydrate as a fuel source
What is the respiratory exchange ratio (RER)?
With anaerobic training, you would expect an increase in these enzymes
What is glycolytic?
The point at which lactate begins to accumulate in the blood at an accelerated rate
What is onset of blood lactate (OBLA)?
The intracellular transporter that permits glucose entry into the muscle cell
What is GLUT4?
This theory explains how ATP is synthesized using an electrochemical gradient of protons across a membrane
What is the chemiosmotic theory?
The equation used to determine energy expenditure (kcal/min) using known VO2 and VCO2 values
What is the Weir equation?
Aerobic training increases the ability to store this substrate
What is fat?
The process by which glucose is created from lactate in the liver
What is the Cori Cycle?
