In the majority of cases for muscle activity, no significant differences were found between the combined and the additive effects (p < 0.05), while for the physiological responses there were mostly significant differences observed. Psychophysical responses indicated that there was a significant difference overall between the additive and combined effects. The results of this study demonstrate that in order to identify risk areas, manipulation tasks and constrained working postures may be considered either in isolation and added together (additive) or as a combined task, since there were very few significant differences observed between these two effects. Further studies are required, however, to provide conclusive evidence.]]> Wed 12 May 2021 18:40:28 SAST ]]> The effect of restricted environments on selected postural, physiological and perceptual responses https://commons.ufh.ac.za/vital/access/manager/Repository/vital:5115 Wed 12 May 2021 17:04:20 SAST ]]> Laboratory investigation of a load carriage task observed in forestry https://commons.ufh.ac.za/vital/access/manager/Repository/vital:5145 Thu 13 May 2021 08:04:09 SAST ]]> The impact of load and frequency on the biomechanical, physiological and perceptual responses to dynamic pushing https://commons.ufh.ac.za/vital/access/manager/Repository/vital:5144 Thu 13 May 2021 06:54:06 SAST ]]> The effect of load and technique on biomechanical and psychophysical responses to level dynamic pushing and pulling https://commons.ufh.ac.za/vital/access/manager/Repository/vital:5110 Thu 13 May 2021 05:20:31 SAST ]]> An analysis of regulatory mechanisms during sustained task execution in cognitive, motor and sensory tasks https://commons.ufh.ac.za/vital/access/manager/Repository/vital:5140 Thu 13 May 2021 04:53:17 SAST ]]> A field investigation into the impact of task demands on worker responses in the South African forestry silviculture sector https://commons.ufh.ac.za/vital/access/manager/Repository/vital:5157 Thu 13 May 2021 04:11:54 SAST ]]> Effects of incremented loads over preferred values on psychophysical and selected gait kinematic factor https://commons.ufh.ac.za/vital/access/manager/Repository/vital:5160 Thu 13 May 2021 01:32:50 SAST ]]>
