Practicing weighted movements at high speeds also causes the nervous system to fire at larger intensities. If an individual loses the weight without being trained to adapt to the transition, he may overexert himself without checking at the end of the movement and overextend a tendon. This is more of a risk when people fully extend their limbs in such movements and do not come to a controlled stop at the end, limiting muscle flexion. Generally, the muscle being extended is more at risk, not one held statically. For example, the quadriceps muscle could overexert in a snap kick trained with ankle weights, but in a rising kick, it is the hip flexor muscle more likely to overextend. In either case, the hamstring and associated ligaments would be at risk for a tear.
