The simultaneous use of electromyography (EMG), strain gauges, and cinematography show that the capacity of continuous displacement from a single peg is based on the following: sequential activity of the tested muscles from front to rear; activity restricted to the short portion of the body in contact with the peg; alternate action of the muscle longissimus dorsi on the two sides, the transition between one side to the other occurring at the site of contact with the peg; unilateral activity of the muscle supracostalis ventralis responsible for a bulging against the peg; a great stability in the direction of the resultant force, which makes only a small angle with the directio of the motion.
肌电图（EMG）、应变仪和电影摄影术的同步使用表明，从单个木桩进行连续位移的能力基于以下几点：受试肌肉从前到后的顺序活动；活动局限于与木桩接触的身体短部分；背最长肌在两侧的交替作用，从一侧到另一侧的转换发生在与木桩接触的部位；腹侧肋上肌的单侧活动导致身体向木桩凸出；合力方向具有很大的稳定性，与运动方向仅形成小角度。
