Ejob = (Sum(Eposi * ti) + Sum(Etaskj) ) /T
Where
- Ejob = avg energy expenditure rate of the job (Kcal/min)
- Eposi = Metabolic energy expenditure rate necessary to maintain the posture (Kcal/min)
- ti = time duration of the ith posture
- Etaskj = net metabolic energy expenditure of the ith task in steady stat (Kcal)
- T = time duration of the job
