The task of material handling is a daily movement as both men and women. This study presents an integrated method of motion analysis of manual lifting load based on the 3D kinematic simulation model and to estimate the internal muscles forces acting on the lumbar spine, intervertebrae disc L5/S1 , besides the analysis of electromyographic muscles. The study explores the biomechanical view in women during manual lifting load based on the NIOSH equation, in two different posture: knee extension .and flexional mode. Were selected as sample 12 university volunteers aged 25.7 ± 4.3 years, mass 55.7 ± 7.0 kg and height of 1.6 ± 0.1 m. The results showed that for physical exercise practitioners, maximum NIOSH load level was reached on the discs established for men when they realized the condition of maximum voluntary contraction. Key words - Occupational biomechanics, manual material handling, NIOSH equation, erector muscle force, electromyography.
