a muscle located on the upper arm; functions to rotate the forearm and flex the elbow
What is bicep
100
three muscles that make up the buttocks; action is to extend and laterally rotate the hip, and to extend the trunk
What is gluteals
100
any body movement carried out by the skeletal muscles and requiring energy
What is physical activity
100
the range of motion in a joint or group of joints, flexibility is related to muscle length
What is flexibility
100
an isotonic contraction in which the muscle gets shorter as it contracts
What is concentric muscle contraction
200
the muscle forming the rounded contour of the shoulder; prevents shoulder dislocation, prime mover of arm away from body
What is deltoid
200
major muscle of the functional core of the body; provide movement and support to the trunk and assist in the breathing process
What is abdominals
200
the amount of force a muscle can produce with a single maximum effort
What is muscular strength
200
the ability of a muscle or group of muscles to remain contracted or to contract repeatedly for a long period of time
What is muscular endurance
200
an isotonic contraction in which the muscle lengthens as it contracts; also called a pliometric contraction
What is eccentric muscle contraction
300
large muscle on the back of the upper limb; responsible for extension of the elbow joint
What is tricep
300
powerful muscle in the back part of the lower leg, runs from its two heads just above the knee to the heel; involved in standing, walking, running and jumping
What is gastrocnemius (calf)
300
planned, structured, repetitive movement of the body designed to improve or maintain physical fitness
What is exercise
300
the proportion of fat and fat-free mass (muscle, bone, and water) in the body
What is body composition
300
rapid stretching of a muscle group that is undergoing eccentric stress (the muscle is exerting force while it lengthens), followed by a rapid concentric contraction
What is plyometrics
400
broadest muscle of the back; responsible for internal rotation of the shoulder joint, helps spine extension and flexion
What is latissimus dorsi
400
one of the three posterior thigh muscles, tendons that make up the space behind the knee; extend the hip, flex the knee, rotate the lower leg when knee is bent
What is hamstring
400
the performance of different types of activities that cause the body to adapt and improve its level of fitness
What is physical training
400
a condition caused by training too much or too intensely, characterized by lack of energy, decreased physical performance, fatigue, depression, aching muscles and joints, and susceptibility to injury
What is overtraining
400
exercise involving a muscle contraction without a change in the length of the muscle
What is Static (isometric) exercise
500
makes up the bulk of the chest muscles; actions primarily responsible for the movement of the shoulder joint
What is pectorals
500
a large muscle group that includes the four prevailing muscles on the front of the thigh; powerful extensors of the knee joint
What is quadriceps
500
the nonfat component of the human body, consisting of skeletal muscle, bone, and water
What is fat-free mass
500
the training principle that fitness improvements are lost when demands on the body are lowered
What is reversibility
500
exercise involving a muscle contraction with a change in the length of the muscle
