Evaluation of the Kaiser Physical Activity Survey in women

Article Abstract:

The Kaiser Physical Activity Survey is fairly accurate in measuring physical activity in women, according to a study of 50 women who wore a Caltrac accelerometer while they engaged in activities of daily living. The results of the survey were compared to accelerometer readings.

Comparison of three methods for measuring the time spent in physical activity

Article Abstract:

This article compares the accuracy of using motion sensors, daily written logs, or weekly telephone surveys to measure the amount of time spent on household, recreational, or occupational physical activities. Results indicate that the three measurement methods produced similar estimates of time spent on moderate and intense physical activities.

Validity of four motion sensors in measuring moderate intensity physical activity

Article Abstract:

This article evaluates the validity of using motion sensors to estimate the energy costs of moderately intense activities such as gardening, housework, and outdoor recreation. Results indicate that motion sensors underestimated the energy expenditure involved in many activities due to their inability to include data from upper body movements.
