Closed skill
Skills not affected by environment and surroundings
Extension of the elbow
Straightening the elbow
Ex. A goalkeeper stretching to save a ball
Flexion at the elbow
Bending of the elbow
Ex. Preparation phase of tennis overhead serve
Eccentric contraction
Muscle contracts as it lengthens
E.g. The downwards phase of a bicep curl
Isometric
Muscle stays the same length whilst producing tension
E.g. the plank
Isotonic concentric
Involves a muscle shortening
E.g. upwards phase of a bicep curl
Isotonic eccentric
Involves the muscle lengthening under tension
Ligaments
