During the upward phase of a biceps curl, the biceps performs what type of contraction?
Answer: Concentric
A concentric contraction occurs when the muscle shortens while producing force.
Holding a plank position involves mainly which type of muscle action?
Answer: Isometric
Isometric contractions produce force without changing muscle length or joint angle.
Which muscle fiber type is most resistant to fatigue and best suited for endurance events?
Answer: Type I
Type I (slow-twitch) fibers have high mitochondrial density and resist fatigue.
Delayed onset muscle soreness (DOMS) is most associated with which type of muscle action?
Answer: Eccentric
Eccentric (lengthening) contractions cause more muscle microdamage and DOMS.
In which anatomical plane does a squat primarily occur?
