Bioenergetics and Exercise Physiology

These flashcards cover key vocabulary and concepts related to bioenergetics and exercise physiology, highlighting the energy systems involved in physical activities and their adaptations.

Bioenergetics

The study of energy flow and conversion in living organisms.

ATP (Adenosine Triphosphate)

The primary energy currency of cells, required for muscle contraction and other cellular processes.

Phosphagen System

An immediate energy system relying on stored ATP and creatine phosphate for short, explosive activities.

Glycolytic System

An anaerobic energy system that breaks down glucose to produce ATP for short to moderate duration activities.

Oxidative System

An aerobic energy system that generates ATP through metabolic pathways involving glucose and fats during long-duration activities.

Glycolysis

The process of breaking down glucose into pyruvic acid with a net gain of 2 ATP.

Citric Acid Cycle

A series of reactions in the mitochondria that generate ATP and release high-energy electrons.

Electron Transport Chain

A series of enzymes that transfer energy from high-energy electrons to produce more ATP, utilizing oxygen.

Energy System Adaptations

Changes resulting from training that improve the efficiency of energy systems: aerobic, phosphagen, and glycolytic.

Anaerobic

A process that occurs without oxygen, primarily within the glycolytic system.

Aerobic

A process that requires oxygen, primarily associated with the oxidative system.

Recovery Strategies

Approaches to facilitate recovery based on the energy systems predominantly used during exercise.

Creatine Phosphate

A molecule stored in the body that rapidly resynthesizes ATP for immediate energy.

Lactic Acid

A byproduct of anaerobic metabolism that can lead to muscle fatigue.

One-Rep Max (1RM)

The maximum amount of weight one can lift in a single repetition for a given exercise.

Energy Demands

The requirement for energy production associated with specific physical activities or exercises.
