There was no significant between group difference in six-minute walk test distance .
Conclusions Our meta- analysis showed WPAM with exercise prescription or advice are superior to no device in improving CRF in the maintenance phase of CR and no cardiac adverse events were reported with WPAM use .
Our qualitative analysis showed evidence in favour of WPAM with exercise prescription or advice for both CRF and step count .
WPAM with exercise prescription or advice did not change sedentary time .
Background Physical activity ( PA ) is a component of cardiac rehabilitation ( CR ) .
However , life-long engagement in PA is required to maintain benefits gained .
Wearable PA monitoring devices ( WPAM ) are thought to increase PA .
There appear to be no review s which investigate the effect of WPAM in cardiac population s. We firstly aim ed to systematic ally review r and omised controlled trials within the cardiac population that investigated the effect WPAM had through the maintenance phase of CR .
We specifically examined the effect on cardiorespiratory fitness ( CRF ) , amount and intensity of daily PA , and sedentary time .
Safety of exercise training for cardiac patients: results of the French registry of complications during cardiac rehabilitation.
BACKGROUND Cardiac rehabilitation is widely recognized as a medical management procedure that reduces mortality , but the cardiovascular safety of exercise training has not been clearly established . Published data are retrospective or out date d , as patient management has substantially progressed in recent years . The aim of this prospect i ve registry was to determine the current complication rate during exercise performed in the course of cardiac rehabilitation . METHODS This study was conducted by the Functional Evaluation and Cardiac Rehabilitation Working Group of the French Society of Cardiology . During a 1-year period , 65 cardiac rehabilitation centers reported that serious events had occurred during or 1 hour after an exercise stress test or a training session .  Severe cardiovascular events were vali date d by a scientific committee . RESULTS A total of 25,420 patients ( 78 % men ; mean age , 61.3 years ) were included in the study . Initial indications for cardiac rehabilitation were post-cardiac surgery ( coronary bypass , 34.3 % ; valvular surgery , 18.4 % ) ; recent percutaneous coronary intervention ( 21.6 % ) ; and other coronary ( 13.2 % ) and noncoronary ( 12.5 % ) conditions . The study population underwent 42,419 exercise stress tests and 743,471 patient-hours of exercise training . Twenty severe cardiac events were reported : 5 were related to exercise testing and 15 were related to exercise training . The event rate was 1 per 8484 exercise stress tests and 1 per 49,565 patient-hours of exercise training ; the cardiac arrest rate was 1.3 per million patient-hours of exercise . Neither fatal complications nor emergency defibrillations were reported . CONCLUSION The frequency of major cardiovascular complications during  supervised exercise training in France is quite low
