Abstract: | The relationship between activity counts from the large-scale integrated sensor (LSI), placed at the hip and ankle, and heart rate-estimated energy expenditure was examined in three nonobese males during three conditions: normal morning activities, a 1-mi walk, and a 2-mi walk. Results showed that estimated caloric expenditure was related to activity counts for both monitoring placements, with correlations between counts and energy expenditure exceedingr=.90. These results show that energy expenditure in the activities sampled can be reliably estimated using activity monitors.This research was supported in part by a grant provided by The John D. and Catherine T. MacArthur Foundation Research Network on the Psychobiology of Depression, Clinical Research Center Grant 5-30915 from the NIMH, and Grant HD 16411 from the NICHD awarded to Dr. Epstein. |
