Trends and Advances in Mechanical Engineering,

4. Conclusions
1) As the Age of Worker increases the VO2 Intake and Heart Rate of worker were increases for the same type
of lifting task. So based on the results it’s recommended that the lower age worker should be preferred for
the MMH task.
2) With the increase in the time duration for MMH task, VO2 intake and HR increases, so proper rest break
should be given between the MMH task and continuity for lifting task for longer time should be avoided.
3) Based on the results the lifting task at higher temperature results in higher physiological strains, so MMH
task at higher temperature should be avoided.
