Describes how to use physical activity instruments in health-related research, and suggests effective ways to collect, score, and interpret physical activity data for research purposes. The 15 chapters discuss procedures for assessing construct validity, nonparametric techniques for analyzing data, and formulas for choosing an appropriate sample size, then outline the principles of using heart rate monitors, pedometers, doubly labeled water, and direct observation to assess physical activity. The closing chapters explore the benefits of incorporating multiple measures to improve accuracy and approaches to measuring environmental and policy variables.
