Endurance-related refers to qualities, processes, and phenomena associated with the capacity to sustain physical or mental effort over extended periods. In sports science, endurance describes the ability to maintain performance in activities that tax the cardiovascular, respiratory, and musculoskeletal systems, or to sustain attention and decision-making under fatigue.

Endurance can be categorized as aerobic endurance (sustained, predominantly using oxygen), muscular endurance (the ability of a muscle or muscle group to perform repeated contractions), and cardiovascular endurance (the efficiency of the heart and lungs to deliver oxygen). Key physiological determinants include VO2 max, lactate threshold, running or cycling economy, and fuel utilization patterns.

Measurement and assessment use aerobic testing, ventilatory threshold, lactate testing, heart rate monitors, and perceived exertion scales to estimate an individual's endurance capacity and trainability.

Training principles emphasize gradual progressive overload, specificity to sport, periodization, and recovery. Common modalities include long slow distance, tempo work, interval training, and resistance exercises to improve muscular endurance. Nutrition and sleep support adaptation and injury prevention.

Endurance concepts also apply to mental tasks, where cognitive endurance involves sustaining attention, working memory, and decision-making under fatigue. Endurance-related research covers training interventions, fatigue management, and performance optimization across athletic, military, clinical, and occupational contexts.
