Answer contract and relax
Explanation:
To pull the rope human body muscles contract and relax those are basically muscles of arms, shoulders, abs, neck and legs. if they twitch and tighten the force cannot be produced, relaxing and twitching leads to lose the rope. tighten and contract may lead to injury to muscle fibre.contract and relax are two opposite forces that work together at the same time in case of rope pulling.
