      <subfield code="a">We examined the effects of posture, weight and frequency on trunk muscular activity and fatigue during repetitive dynamic lifting. Electromyographic signals from eight primary trunk muscles were collected during 120 min for four different tasks conditions. It was seen that the muscles became fatigued faster for the light load-high frequency task than for the heavy load-low frequency task</subfield>
