The mean (±SE) uniaxial punching forces to the body for maximum force was 3244 ±48 N and for maximum speed was 2256 ±44 N and to the head 3956 ±110 N and 2459 ±61N respectively. The linear recruitment of punches delivered to the body as shown in figure 1 commenced with the initial recruitment of the quadriceps muscle rectus femoris which extended the rear leg at the knee.Recruitment sequenceFigure 1.
