✦ Synopsis
occurring in the posture with a difference in level of 1.0 m between milker and cow. In this posture, only 15% of the maximum muscle strength was used to counteract the load moments. Because the load during machine milking is relatively static, the recorded muscle activity is considered to be sufficiently high to partially occlude circulation to the muscle and therefore may result in muscle fatigue and pain. 22.2.45 (120009)
