A situation occurring during a movement that requires simultaneous activation of both limbs, when the total force exerted by two limbs is less than the sum of the forces produced by the left and right limbs acting alone. The bilateral deficit varies according to the type of movement and between individuals. For example, bilateral deficit tends to be greater for cycling than rowing; it may even be absent in athletes who train with bilateral movements. Some elite rowers actually perform better in the bilateral condition than unilateral condition.
