Question

what type of exercise and muscle contraction is pictured below? (plank hold) isometric isotonic isokinetic

Explanation:

Isometric exercise involves muscle contraction without significant joint movement. In a plank hold, muscles (like core muscles) contract to maintain a static position, which fits the isometric definition. Isotonic involves muscle shortening/lengthening with joint movement (e.g., bicep curl). Isokinetic requires specialized equipment to control movement speed.

Answer:

Isometric
