High-Calorie-Expenditure Exercise

Abstract: Background-More than 80% of patients entering cardiac rehabilitation (CR) are overweight, and Ͼ50% have metabolic syndrome. Current CR exercise protocols result in little weight loss and minimal changes in cardiac risk factors. We sought to design an exercise protocol that would lead to greater weight loss and risk factor change. Methods and Results-We performed a randomized controlled clinical trial to evaluate the effect of high-calorieexpenditure exercise (3000-to 3500-kcal/wk exercise-related energy expend… Show more

“…Using this high kcal regimen, the investigators reported a significantly greater weight loss with improvement in insulin sensitivity when compared with standard moderate intensity protocols. 45 Many recent innovations in ET protocols have included interval training, often with high intensity interval training (HIIT). The differentiating factors between HIIT and continuous moderate intensity continuous training (MICT; usual therapy) are that usual therapy involves continuous maintenance of workload at an intensity of 50%-65% of the peak, often measured as peak O2 uptake (VO2) or peak HR.…”

“…(36,74,75,(77)(78)(79)(80)(81)(82)(83)(84)(85)(86) Weight loss has been associated with marked improvements in arterial pressure and LV geometry, potentially improving HTN. (86) Additionally, exercise, a potential tool for weight loss, has been associated with increases in cardioprotective HDL-C, increased insulin sensitivity, and a decrease in the prevalence of MetS and DM.…”

“…(1,(88)(89)(90) What is certain is that fitness is important to improve prognosis among CAD patients (81)(82)(83) and, therefore, physical activity, exercise training and fitness improvements, with potentially accompanying purposeful weight loss, should be incorporated into treatment plans of overweight or obese patients with CAD. (84,85) …”

“…In the present study all, except four subjects, had a BMI>25, and were categorized as overweight or obese. Additionally as reported earlier 80% of patients participating in cardiac rehabilitation are overweight [19,40]. Others have shown that an increase in strength is impaired by accumulation of extracellular fat in muscles [41].…”
