). Nevertheless, total caloric expenditure rates, using validated accelerometry and/or breath-by-breath indirect calorimetry methodologies, appear to be positively associated with overall exertional stress ( Vernillo et al., 2017 ; Williamson, 2016 ). Data have shown caloric expenditure of 3,831–4,999 kcal
