Featured Article of the Week - Validity of the Talk Test as a Method to Estimate Ventilatory Threshold and Guide Exercise Intensity in Cardiac Patients
An exercise prescription is ideally based on information derived from symptom-limited exercise tolerance testing. Cardiopulmonary exercise testing (CPX) is considered the gold standard for determining fitness. Unfortunately, CPX is not commonly done in cardiac rehabilitation (CR) due to the costs and the requisite technological skills. Therefore, inexpensive, practical, valid, and reliable tests to prescribe and monitor exercise intensity, such as the Talk Test (TT), are desirable. The talk test is a simple way to measure relative intensity. In general, if you are doing moderate-intensity activity, you can talk but not sing during the activity. Exercise greater than the ventilator threshold (VT) does not allow comfortable speech. The aim of the present study was to determine the relationship between the TT and VT in a population of patients with cardiac disease and to compare the TT and recommended exercise intensity guidelines. This relatively small study cohort included 20 patients (18 males) aged 65 yr with ischemic heart disease, valve disease, or heart failure. A CPX was used to estimate VT. The study results indicate that while there is a poor correlation between TT and determining the VT, the TT can be used as a practical method to prescribe exercise intensity in patients in CR.
- JCRP is continuing the celebration of our 40th year by including some special features in Volume 40. In this 5th issue of JCRP Volume 40 are two excellent Invited Reviews (Stroke Patients in CR; Muscular Strength and CVD Update), an Invited Commentary with an update on the Million Hearts Initiatives, a Commentary on the Importance of Moving More during the pandemic, and a number of excellent research papers.
- Please note the Featured Article of the week section above. Our Editorial group provides a brief overview of one article each week to call your attention to some of the key information you can learn from articles in this issue.
- I also call your attention to the Literature Update section with insights from two or our Associate Editors - Dr. Brubaker and Dr. Kalra.
- Plus, this issue includes the abstracts that will be presented at this year's AACVPR Annual Meeting. Two investigators shared the 'best abstract' award and we are pleased to have the full manuscripts of both of these studies in this issue.
- I encourage you to post links to specific articles from this issue on your Facebook page and to tweet the links on your Twitter account (use the icons on our home page for both of these JCRP Social Media accounts). Doing so helps both Clinicians and Researchers to stay current with the latest research in Cardiac Rehabilitation, Pulmonary Rehabilitation, and Prevention. This will ultimately have a positive influence on patients in Cardiopumonary Rehabilitation Programs.
