The object of this study is to examine co-activities of eight muscle group in various lifting conditions. A total of 40 voluntary subjects with no experience of low back pain participated in this experiment. The muscle activities of interested were bicep brachii, thoracic erector spinae, lumbar erector spinae, latissimus dorsi, external oblique, rectus abdominis, rectus femoris, and semitendinosus of the right side body. Surface EMG signals were obtained in static holding postures of 3 kneeing angles, 5 trunk flexion angles, 2 horizontal liftingdistances, and 3 loading conditions. After recording, the percentages of maximum voluntary contraction (NEMG) and relative activity level …
