The physiological cost of three different methods of lifting in sagittal and lateral planes

摘要: Abstract Twelve young adults (six males—mean age 24.1 years, mean weight 75.4 kg and height 176.6cm—and six females—mean 20years, 59.8kg 162.6cm) lifted lowered a of 10 from 13.5 cm at three-quarters reach. The was in the sagittal, 30° lateral 60° plane by stoop, squat free-style techniques times per minute for period 4min, subjects rested lOmin. steady-state values oxygen consumption during these activities were measured. also subjectively assessed relative degree tiresomeness tasks studied. each significantly different others (p<0.01). stoop method lifting required least amount had lowest per-minute inspiratory ventilation volume. highest activities...
