Bioenergetics and Exercise Physiology

These flashcards cover key vocabulary and concepts from the lecture on bioenergetics and exercise physiology.

Bioenergetics

The study of energy flow and conversion in living organisms.

ATP

Adenosine Triphosphate, the primary energy currency of cells needed for muscle contraction.

Phosphagen System

An immediate energy system using stored ATP and creatine phosphate, primarily for short, explosive activities.

Glycolytic System

An anaerobic energy system that breaks down glucose to produce ATP, functioning for short to moderate durations.

Oxidative System

An aerobic energy system using carbohydrates and fats to produce ATP over long durations.

Cellular Metabolism

The set of life-sustaining chemical reactions in organisms which includes the processes of energy production and utilization.

Glycolysis

The metabolic pathway that breaks down glucose into pyruvic acid, producing ATP and high-energy electrons.

Citric Acid Cycle

A series of chemical reactions used by all aerobic organisms to generate ATP through the oxidation of acetyl CoA derived from carbohydrates and fats.

Electron Transport Chain

A sequence of protein complexes that transfer electrons and pump protons to produce ATP via aerobic respiration.

Energy System Integration

The concept that all three energy systems work simultaneously but dominate at different intensities.

Strength Training

Physical exercise focused on enhancing muscular strength and endurance primarily using the phosphagen system.

Endurance Activities

Exercises such as long-distance running or cycling that primarily depend on the oxidative system for energy.

Lactic Acid

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

Active Recovery

A recovery strategy involving low-intensity exercise to facilitate recovery based on energy system utilization.

High-Intensity Training

Exercises performed near maximum effort that predominantly use the phosphagen system.

Recovery Strategies

Approaches to restoring energy after exercise, which depend on the energy systems used during the activity.
