What is fatigue?

A state of physical and/or mental weariness resulting from exertion, impairing performance and efficiency.

What are the two types of fatigue?

Central fatigue and peripheral fatigue.

What is central fatigue?

Fatigue that originates in the central nervous system, involving reduced neural drive from the brain to the muscles.

What is peripheral fatigue?

Fatigue that occurs within the muscles, related to metabolic changes in muscle fibers.

What is the ATP-PC system?

An energy system that provides immediate energy through the breakdown of phosphocreatine.

What causes fatigue in the glycolytic system?

Accumulation of lactic acid during anaerobic ATP production.

What leads to fatigue in the oxidative system?

Glycogen depletion and inability to sustain energy production.

How does lactic acid accumulation affect fatigue?

It lowers pH and inhibits enzyme activity, contributing to muscle fatigue.

What is glycogen depletion?

The reduction of muscle glycogen stores during prolonged exercise, limiting ATP availability.

What role do electrolytes play in fatigue?

Electrolyte imbalance can disrupt muscle contraction and lead to fatigue.

What is neuromuscular junction fatigue?

Reduced efficiency in the transmission of signals from nerves to muscles.

How does motivation affect fatigue?

Higher motivation levels can help athletes push through physical fatigue.

What is the Rating of Perceived Exertion (RPE) scale?

A scale used to measure the subjective feeling of how hard an exercise feels.

What is mental fatigue?

Fatigue resulting from prolonged cognitive activity, impairing physical performance.

What is periodization in training?

Structuring training into cycles to balance workload and recovery.

What is carbohydrate loading?

A nutritional strategy to increase muscle glycogen stores before endurance events.

What is active recovery?

Low-intensity exercise post-training to promote blood flow and nutrient delivery.

Why is sleep important for athletes?

Adequate sleep is essential for physical and mental recovery.

What are the physiological aspects of fatigue?

Includes energy systems, metabolic factors, and neuromuscular factors.

What are the psychological aspects of fatigue?

Includes motivation, perception of effort, and mental fatigue.

What is tapering in training?

Reducing training volume before a major competition to allow full recovery.

How can hydration prevent fatigue?

Maintaining fluid balance prevents dehydration and electrolyte imbalances.

What is the impact of fatigue on athletic performance?

Fatigue can impair performance, efficiency, and overall health.
