Total body capacity correlated with basal metabolic rate

This study was conducted to establish the relationship between a new bioelectrical parameter, total body capacitance (TBpF), as an expression of body cell mass, measured using an impedance analyser and basal metabolic rate (BMR), by indirect calorimetry in 75 healthy subjects (38 females and 37 males, aged between 13 y and 43 y). A significant high correlation was found between TBpF and BMR (r = 0.992, SEE = 238 kcal) with the equation: BMR (kcal day-1) = Capacity (pF) x 2.29.
