Ergonomics is the system design compressed of man-machine and environment relationship to bring about some output against given inputs by considering different physical, anatomical, physiological and psychological limits of the human being. Based on different workloads and speeds (rpm), the experiment was conducted on MONARK 828E Ergometer, to evaluate heart rates of different age groups with variable weights and heights. The farm workers of 25-30 years age group have developed a maximum working heart rate as compared to other age groups of 30-35 and 35-40 years. The Energy Expenditure Rate (EER) for all the farm workers obtained was graded as 'Moderately Heavy'. The Body Mass Index (BMI) of age groups 25-30 and 30-35 years were considered as 'Normal' and 35-40 were considered as 'Obese Grade I'. The Ponderal Index (PI) of all age groups, i.e. 25-30, 30-35 and 35-40 years were 'Ectomorph' in nature.
