Although many schools of thought have emerged from this work, one of the most promising has been Optimal Foraging Theory, which attempts to model the optimal subsistence behaviour in a given context using environmental and anthropological data as inputs. One of the major limitations of Optimal Foraging Theory is that it requires a broad base of accurate data on the costs and benefits of different subsistence activities in order to create precise models. To help address this problem, we used hip-worn Triaxial Accelerometry to estimate relative energy expenditure during specific subsistence-related activities among the Baka of southeastern Cameroon. Our results demonstrate that hunting activities among the Baka involve significantly more movement than gathering or agriculture, implying more energy expenditure, while gathering and agricultural activities involve roughly similar levels of movement. Through the analysis of other variables, we also found that men perform significantly more movement than women when periods of rest are not included. However, there is no significant difference between these values when periods of rest are included. Furthermore, there are no significant differences in the average movement performed per unit time (including or excluding rest), or in the proportion of time spent at rest, between villages.Show less
