Abstract

PURPOSE: To examine the validity and usability of a paper log for evaluating exercise duration in older women. METHOD: Data from 23 females (mean age = 70.4 years) who completed an 8-week pilot randomized controlled trial investigating the effects of yoga and aerobic/strength training on knee osteoarthritis were included in this secondary analysis. Participants were asked to complete a paper log and video recording of their home exercise sessions. RESULTS: Concurrent validity was high between minutes reported on the paper logs and video record-ings during Weeks 2 to 7 (r = 0.878). Usability was high, with participants completing 79% to 91% of paper logs and 74% to 100% of video diaries weekly. Overall minutes reported on the paper exercise logs and video diaries were positively correlated to Physical Activity Scale for the Elderly scores at 8 weeks. CONCLUSION: Exercise logs are a valid and useful method in assessing adherence to prescribed exercise duration in unsupervised home programs.
