Cards

Term
muscle strength
Definition
the amount of force that can be exerted by a muscle group for one movement or repetition.
Term
muscle endurance
Definition
the ability of a muscle group to maintain a continuous contraction or repetition over a period of time.
Term
conditioning
Definition
the development of high levels of muscular strength and endurance and high levels of cardiorespiratory endurance.
Term
weight training
Definition
exercise program using free or stationary weights for the purpose of increasing strength, endurance, power, skill, and flexibility.
Term
body composition
Definition
the proportion of body fat to lean body tissue
Term
cardiorespiratory endurance
Definition
the ability of the heart to deliver oxygen and nutrients to vital organs of the body.
Term
aerobic
Definition
refers to an activity in which demands of the muscles for oxygen are met by the circulation of oxygen in the blood
Term
anaerobic
Definition
the process of energy production in which the oxygen supply cannot keep face with tissue demands
Term
tendon
Definition
a cord of connective tissue that attaches muscle to bone
Term
ligament
Definition
connective tissue that attaches bone to bone
Term
agonist
Definition
muscle responsible for movement
Term
antagonist
Definition
muscle that relaxes to allow agonist to contract
Term
atrophy
Definition
decrease in the size of muscle tissue
Term
hypertrophy
Definition
enlargement of muscle size.
Term
muscle soreness
Definition
Immediately from increased hydrostatic pressure. Second happens later influx of calcium ions into the mitochondria.
Term
isotonic
Definition
exercise against resistance while the load remains constant, with the resistance varying with the angle of the joint.
Term
eccentric
Definition
exercise in which the muscle lengthens as it develops tension
Term
isometric
Definition
a contraction performed against a fixed or immovable resistance where tension is developed in the muscle, but there is no change in the length of the muscle or angle of the joint.
Term
isokinetic
Definition
a contraction in which the muscle contracts maximally at a constant speed over a full range of joint movement against a variable resistance.
Term
flexibility
Definition
the range and the extent of the movement of a joint
Term
ballistic stretching
Definition
rapid bouncing, jerking types of muscle movements
Term
static stretching
Definition
a stretching method that consists of stretching the muscle slowly and gradually.
