Description
Summary:To determine if simple field-based individual user calibrations could improve the relationship between accelerometer PAC and PAEE. Following ethical approval, 32 participants (16 female and 16 male, body mass 67.9 + or - 12.4 kg, stature 1.71 + or - 0.10 m, estimated VO sub(2)max 44.3 + or - 8.5 mL super(.)kg super(-1) super(.)min> super(-1)) volunteered for the study. During 10 days of military training, PACwere measured using a 3-dimensional accelerometer device worn around participants' waist and PAEE was measured using DLW. Mean 10 day PAC and PAEE were 536,341 + or - 55,143 counts super(.)day super(-1) and 1,600 + or - 386 kcal super(.)day super(-1), respectively. PAEE showed a moderate relationship with PAC (r=0.44, p=0.02) and a stronger relationship with PAC sub(MSFT) (r=0.71, p
