Overview

Fitness, in the physiological sense, is the capacity to perform physical activity and meet the demands of daily life, sport, and exercise, encompassing components such as cardiorespiratory endurance, muscular strength and endurance, flexibility, and body composition. It is developed through regular physical activity that produces adaptations in the cardiovascular, respiratory, muscular, and metabolic systems, and it is a determinant of health, functional ability, and resistance to chronic disease. In Sports and Exercise Medicine, fitness is assessed through exercise capacity and activity measures and is the target of training prescription, with attention to how physical activity influences sleep, cognition, cardiovascular risk, and metabolic health across the lifespan. The peer-reviewed work assembled here that bears on fitness includes the effects of physical activity on sleep among adolescents and adults, the influence of aerobic and cognitive training on working memory and executive function in ageing, comparison of walking performance under differing conditions, and the relationship of daily activity and exercise capacity to cardiovascular risk factors. Across these studies fitness is approached through the physiological and health consequences of physical activity and exercise. Defining fitness as the trainable capacity for physical work, underpinned by cardiorespiratory, muscular, and metabolic adaptation, provides the framework for examining exercise prescription, activity measurement, and the contribution of fitness to health within Sports and Exercise Medicine.
