Chapter 8: Exercise Metabolism & Bioenergetics Flashcards
Bioenergetics
Study of energy in human body.
Metabolism
Chemical reactions that occur in the body to maintain itself.
First Law of Thermodynamics
Energy cannot be created or destroyed but simply converted from one form to another.
Ventilatory Threshold 1 (VT1)
When body uses an equal mix of carbohydrate and fat as fuel sources.
Ventilatory Threshold 2 (VT2)
When glucose provides most of the energy.
Insulin Resistance
When cells are unable to respond to insulin.
Type 2 Diabetes
Adenosine diphosphate (ADP)
High-energy compound in cells. Important for muscle contraction and helps heal blood vessels.
ATP-PC System
Energy system that provides energy very quickly..
Adenosine Triphosphate (ATP)
Main form of energy.
Steady-State Aerobic Exercise
Exercise that stays at a fixed intensity.
Excess Post-Exercise Oxygen Consumption (EPOC)
When body’s metabolism is elevated after exercise.
Total Daily Energy Expenditure (TDEE)
Total amount of energy used in a day.
Resting Metabolic Rate (RMR)
When burning energy (calories) while resting.
Exercise Activity Thermogenesis (EAT)
Calories burned through structured exercise or training.
Thermic Effect of Food (TEF)
Energy required to digest, absorb, and process nutrients that are consumed.
