Your school wins the homecoming football game against its biggest rival. you watch as the smallest cheerleader tries to lift up the heaviest linebacker in her excitement. as she strains against his 300 lb. load and does not move him, what type of muscle contraction are her muscles experiencing?

Therefore the cheerleader's working muscles are at an extended length, under maximal contraction, a classic example of eccentric muscle contraction.
