3D Body Scan Predictors of Increased Ventilatory Responses to Vest-Borne Military Load Carriage
Abstract
This study sought to quantify the effect of weighted vest mass on respiratory rate (RR) during military load carriage, and analyze 3D body scanner (3DS) measurements to identify anthropometric predictors to explain individual variability. Volunteers included 20 U.S. Army Soldiers and civilians (4 women, 16 men; 17 Soldiers, 3 civilians; age, 28 8 years; height, 174 10 cm; body mass, 81 17 kg). Each participant was assessed using a 3D body scanner before participating in a series of four steady-state loaded walking trials at varying speeds (0.00, 0.45, 0.89, and 1.34 ms-1) with weighted vests of four randomized weights (0, 22, 44, and 66 body mass). Data suggest larger individuals and those with larger hip circumferences are more likely to exhibit increased ventilatory responses to external loading than smaller individuals with smaller hip circumferences. 3DS measurements may be an efficient tool for predicting potential for increased ventilatory responses to vest-borne load carriage, and can potentially aid in identifying individual Soldiers susceptible to cardiorespiratory strain.
