WorkplaceTesting explains Energy Expenditure
Energy expenditure is a measurement of the amount of energy used by a person doing all activities over a specific period of time. This is important in the field of ergonomics and workplace wellness. For example, in sedentary jobs where a worker is typically sitting in front of a desk for an 8 hour day, studies have shown that alternating between sitting and standing throughout the can moderately increase the person's energy expenditure which will, in turn, help decrease or maintain weight. Also, it is important to understand energy expenditure when dealing with more demanding jobs to ensure that a worker is not over exerting and exposing themselves to increased injury risk due to fatigue.
