Knowra Physical fitness Physical fitness Physical fitness is the capacity to perform physical activity effectively. It comprises attributes such as cardiorespiratory endurance, muscular strength, flexibility, and body composition.
Cardiorespiratory fitness : The ability of the heart, lungs, and circulatory system to supply oxygen during sustained activity. It captures the endurance component of physical fitness.
Exercise prescription : A plan specifying exercise type, intensity, duration, frequency, and progression for an individual. It turns fitness goals into a structured activity plan.
Cardiovascular adaptation to exercise : Changes in heart and circulation function that develop in response to repeated exercise. These adaptations can increase endurance and oxygen delivery.
Physical activity and health : The relationship between bodily movement and outcomes such as chronic disease, function, and well-being. Fitness is one pathway through which regular activity relates to health.
Muscular strength : The capacity of a muscle or muscle group to exert force against resistance. It describes force production, a core component of physical fitness.
Physical fitness test : A standardized procedure for measuring one or more components of physical fitness. It estimates capacities that training aims to improve.
Skeletal muscle hypertrophy : An increase in skeletal muscle fiber size, commonly induced by resistance training. It helps explain gains in muscular strength and size.
Cardiovascular disease : A group of disorders affecting the heart and blood vessels. Cardiorespiratory fitness is associated with cardiovascular health and risk.
Muscular endurance : The capacity of muscles to sustain repeated contractions or maintain force over time. It distinguishes repeated effort from maximal strength.
VO2 max : The highest rate at which the body can take up and use oxygen during intense exercise. It is a widely used measure of cardiorespiratory capacity.
