Crouter’s main research interests are in the area of measuring physical activity and energy expenditure in adults and youth using devices such as accelerometers, pedometers and heart rate monitors. Much of his work has been focused on improving how accelerometers are used to estimate energy expenditure in free-living youth and adults and he has developed novel techniques for these estimations of energy expenditure using accelerometers. Currently, Crouter is working on the use of machine learning algorithms for classification of activity type and prediction of energy expenditure using accelerometers worn at different body locations.

Title: Novel Approaches for Predicting Unstructured Short Periods of Physical Activities in Youth
Funder: National Institutes of Health (R01HD083431-02; 06/06/2016-03/31/2020)
Role: Contact PI; Co-PIs: W. Ding (UMass Boston) and E. Keogh (U.C. Riverside)
Description: This project will develop and validate machine learning algorithms using raw accelerometer data collected at the hip or wrist for use in youth. These algorithms will be able to detect the start and end times of free-living physical activity bouts, classify the type of activity being performed, and estimate energy expenditure, significantly improving upon current methods.

Title: Neighborhood Risk Factors for Falls in the Elderly
Funder: National Institutes of Health (R56AG028738-05A1; 09/30/2017-08/31/2019 (NCE))
Role: Co-I (PI of sub-contract); PI: W. Li (UMass Medical School)
Description: This study investigates the differences in time and space use in relation to falls among older adults living in rural, suburban, and urban neighborhoods.

Crouter is the director of the Applied Physiology Laboratory at The University of Tennessee. He is a Fellow of the American College of Sports Medicine, is an ACSM Certified Clinical Exercise Specialist, and has served on several committees of the ACSM. He is an associate editor for Medicine and Science in Sports and Exercise, and serves on the editorial board for two journals (ACSM’s Health and Fitness Journal and Journal for the Measurement of Physical Behaviors). Crouter also serves on committees within the National Physical Activity Plan Alliance (U.S. report card for children and adolescents advisory committee) and Centers for Disease Control and Prevention and National Collaborative on Childhood Obesity Research (development of a youth compendium of physical activities).
