Durability as an index of endurance exercise performance: Methodological considerations

Area of Science:

• Sports Science
• Exercise Physiology
• Human Performance

Background:

• Endurance athletes use physiological assessments for performance prediction and training monitoring.
• Current assessments are typically done in a rested state, but key variables decline during prolonged exercise.
• Durability is defined as resilience to physiological and performance decline during or after extended exercise.

Purpose of the Study:

• To review current methods for measuring athlete durability.
• To highlight considerations for designing appropriate durability assessment protocols.
• To ensure reliable and comparable durability measurements in research and applied settings.

Main Methods:

• Review of existing literature on durability assessment in endurance athletes.
• Analysis of how fatiguing protocol design influences durability profiles.
• Identification of factors impacting durability measurements, such as nutrition and environment.

Main Results:

• The construction of fatiguing protocols significantly affects durability profiles.
• Greater exercise intensity and duration lead to more pronounced deterioration of baseline measures.
• Controlling for nutrition and environmental factors is crucial for repeatable durability outcomes.

Conclusions:

• Durability assessment protocols must be carefully designed to be appropriate for the research question or applied context.
• Consideration of athlete training status is important when selecting durability assessment parameters.
• Standardized and controlled protocols are essential for accurate durability profiling in both research and practical applications.
