Clinical guidelines and decision support systems (e.g. EXPERT tool) assist clinicians in selecting appropriate exercise intensities for patients. However, a recent study indicated that guidelinebased intensity domains for CVD patients seem inconsistent. PURPOSE: We aim to investigate the applicability and suitability of the exercise guidelines for the calculation of personalized exercise targets and progress monitoring in a telerehabilitation setting. METHODS: In an appbased telerehabilitation program, we prescribed guidelinebased personalized exercise targets with the EXPERT tool. The targets were converted into Metabolic Equivalent of Task (MET) values using the guidelinebased exercise intensity domains and ACSM's guidelines for exercise testing and prescription. Patients could log cardio (e.g. walking) and noncardio (e.g. gardening) physical activities in the app. Progress towards the targets was determined using ACSM's guidelines and activity specific MET values from the Compendium of Physical Activities. We evaluated our approach in a crossover trial with 32 coronary artery disease patients who used the app for 710 weeks. Application logs and CPET data (collected before and after using the app) were analysed. RESULTS: During the crossover trial, 4 patients dropped out and 4 patients did not log any activities. Of the remaining 24 patients, 83% achieved their minimum exercise targets every week and 8% reached their maximum targets at all times. In general, 63% of patients achieved their maximum exercise targets for at least half of the weeks. However, amongst patients who reached their maximal targets 70% of the time there was no significant difference in VO2 max (P=0.268). For example, one patient exceeded his maximum exercise target at all time, but still did not improve VO2 max. Furthermore, 46% of the patients reported mostly noncardio physical activities, including household chores, gardening, and mowing the lawn. We found a significant difference in achieving the minimum (P=0.018) / maximum (P=0.001) exercise target when considering only cardio activities or all physical activities logged in the app. CONCLUSION: The guidelinebased intensity domains and activity specific MET values from the Compendium of Physical Activity seem nonoptimal for determining personalized exercise targets to improve maximal exercise capacity. Patients often overachieved their prescribed exercise targets and yet failed to gain a significant increase in maximal exercise capacity. Therefore, the approach of this relatively short study was not sufficient to increase maximal exercise capacity but may be sufficient to have a positive effect on health and submaximal exercise capacity. | Document URI: | http://hdl.handle.net/1942/31478 | Category: | C2 | Type: | Conference Material |
