The following list is common words and terms relating to physical fitness.
The term for when a bone moves away from its anatomical position.
Returning back to the anatomical position from the abducted position.
(With oxygen) – Where oxygen, supplied by the lungs and pumped by the heart, is carried by the blood to the working muscles. Energy is burnt along with oxygen in great quantities during a workout. To achieve this, large muscle groups have to move in a rhythmical motion over a period of time. Using exercise equipment such as treadmills, bikes, rowers, and ellipticals will all provide an aerobic workout.
Ability to stop, start, and move the body quickly in different directions.
A muscle that is very effective in causing a certain joint movement. Also called the prime mover.
Compounds containing Nitrogen that form the building blocks of protein
(Without oxygen) – An activity in which oxygen demands of muscles are so high or so fast that they rely upon an internal metabolic process to take place to supply the energy. Sprinting and weight training with free weights like dumbbells, barbells and weight plates, or on a multi gym are examples of anaerobic training.
A muscle, that causes movement of a joint in the opposite direction of that of the prime mover. (Agonist )
Withering away of a muscle or body part due to lack of use.
Science concerned with the internal and external forces acting upon a human body and the effects produced by this force.
The pressure exerted by the blood on the vessel walls. Two pressures are measured, systolic is the high reading, which is when the heart beats and pumps the blood through the body, and diastolic; the low reading taken when the heart is at rest during beats.
The measure of the various components of the body, especially fat and muscle.
Body Mass Index (BMI)
A calculated measure of the relationship between height and weight. Divide weight in kilograms by height in meters squared.
Training to increase the muscular size, definition and symmetry of the body.
Gaining body weight by adding muscle, body fat, or both.
The smallest blood vessel; the link between the end of the arteries and the beginning of the veins.
A type of involuntary muscle tissue found only in the heart.
Pertaining to the heart and blood vessels.
Physical conditioning that strengthens heart and blood vessels
A sequence of short exercises done one after the other in the same workout. Can be all one type of exercise such as resistance training or a mix of resistance and aerobic.
When muscle contracts and shortens.
A period of light activity, following moderate to heavy exercise.
Where you perform different activities to achieve a total body workout.
Reducing body fat and water retention to increase muscle definition.
Exercise designed to improve the health and fitness of the heart and lungs.
The muscle action that occurs when the muscle lengthens.
A group of hormones released during exercise that are similar to morphine. Normally produced by the pituitary gland to help reduce pain, anxiety and stress.
The ability of a muscle to produce force continually over a period of time.
Body part going from a bent to straight position, as in leg extension.
Fast Twitch Fibre
A muscle fibre characterised by fast contraction time, making the fibre suited for high power, explosive activities.
Muscles that stabilize a bone during motion. Also known as stabilizers.
Bending a body part in contrast to extending, resulting in a decrease in the angle of a joint, as in leg curl.
To move joints through a full range of motion without pain.
The form in which carbohydrates, (glucose), are stored in the muscles and liver.
Increase in the size of a tissue or organ due to increased cell size.
Chemicals that are secreted by an endocrine gland, that effect cells, organs and tissues in specific ways.
An exercise where you have accommodating resistance and controlled speed, resulting in maximum resistance throughout the full range of motion. Some multi gyms and weight machines can offer this.
A muscle contraction where the muscle maintains a constant length and the joints do not move. Pushing against an immovable object such as a wall is an isometric exercise.
A muscle contraction in which the force of the muscle is greater than the resistance, resulting in the movement of joints and the shortening of the muscle. Lifting free weights is a classic isotonic exercise.
Strong tissue that connects the articulating surfaces of bones together.
The ability of a muscle to generate the maximum amount of force.
A protein involved in muscle contraction.
Applying a greater load than normal on a muscle to increase its size.
Oxygen Consumption (VO2)
The rate at which oxygen is used during a specific level of an activity; oxygen uptake.
Substance composed of amino acid chains. It is used for repair and growth of tissue as opposed to fuel for the body.
Slang meaning the muscles have been made larger by increasing blood supply to them through exercise.
One complete movement of an exercise.
The movement of a bone along its longitudinal axis.
The performance of a specific number of Reps.
Slow Twitch Fibre
A muscle fibre characterized by slow contraction time making it suited for low-power output activities.
A training partner who is there to assist and help prevent injury when performing a specific exercise.
Heart rate greater than 100 beats per minute at rest. May be seen in people who are out of condition or under stress.
Strong tissue, that connects muscle to bone.
A hormone responsible for male sex characteristics.
Physical activity of light to moderate intensity prior to a workout.
Lifting weights, or other forms of resistance training, to develop strength, muscular endurance, and/or muscle size.
