CONCLUSIONA linear model of recruitment of the muscles under investigation applied best in the case of maximum force punches delivered to the body with the importance of early recruitment of the rectus femoris, gastrocnemius, and biceps femoris muscles in the initiation of punch delivery evident particularly when punches were delivered with an aim of maximum force. The punching force to the head was 38% greater when maximum force was a priority relative to when delivery was for maximum speed, and this was associated with increased activity of 27% in the large rectus femoris muscle involved in rear leg extension.Maximum punching force and speed starts with the recruitment of muscles in the legs and a pathway of force travels through the human body to the point of impact. Coaches should consider focusing on developing such muscular recruitment sequence patterns, especially with young boxers.
