Abstract:The Physical Activity Compendium (PAC; Ainsworth et al., 1993, 2000) is commonly used to estimate physical activity (PA) related energy expenditure of self-report PA measures. PAC, however, cannot be applied to persons with disabilities (PWD) due to: (a) lack of PAs done by PWD and (b) large inter- and intra-variability among PWD. This study evaluates the "FITME" model (Lee & Zhu, in review), which includes developing a compendium supplement for persons with spinal cord injury (PSCI) and applying individual calibration (IC), by applying it to PSCI. Nineteen males and 12 females with complete and incomplete spinal cord injury (height: 161.26+/-22.99 cm, weight: 60.52+/-15.32 kg, and age: 18-45 yrs.) participated. Ten PAs were tested, three low-intensity (6 MET). Those activities were classified into three categories to construct a mini-compendium supplement: Activities by Both able- and disable-bodied populations with Similar METs (ABS), Activities by Both able- and disable-bodied populations with Different METs (ABD), and Activity by targeted Disability population Only (ADO). The ten PAs' RMR and oxygen consumptions were measured by indirect calorimetry (COSMED, Italy). Means of MET values in each PA by group and category were computed. Using z-tests, MET values between the compendium supplement and PAC were compared. METs were compared by gender, injury level, and complete lesion using t-tests. Means and SD of R2 and SEE applying regression analysis, averaged absolute error %, and mean signed difference (MSD) were calculated by each of 1,012 k-pairs of IC and cross-validation. Conclusions were: (a) A mini-version of a compendium supplement for PSCI was successfully developed and activities were classified into three categories, ABS, ABD, and ABS. Ten participants seem to be enough to determine MET values for PSCI; (b) IC is better than group calibration (GC), reducing error rate up to 7% from GC; (c) A wide range of intensity is required to obtain a lower error rate in IC; and (d) Future research should focus on developing simple and economical methods to determine a PA's MET value and identify factors that lead to error in the IC process.
