Are first ventilatory threshold and 6-minute walk test heart rate interchangeable? A pilot study in healthy elderlies and cardiac patients
International audience; BACKGROUND: Heart rate (HR) at the ventilatory threshold (VT) is often used to prescribe exercise intensity in cardiac rehabilitation. Some studies have reported no significant difference between HR at VT and HR measured at the end of a 6-min walk test (6-MWT) in cardiac patients. The aim of this work was to assess the potential equivalence between those parameters at the individual level. METHOD: Three groups of subjects performed a stress test and a 6-MWT: 22 healthy elderlies (GES, 77 +/- 3.7 years), 10 stable coronary artery disease (CAD) patients (GMI, 50.9 +/- 4.2 years) and 30 patients with chronic heart failure (GHF, 63.3 +/- 10 years). We analyzed the correl…
''High-Intensity Interval Training in Cardiac Rehabilitation''
Guiraud, Thibaut | Nigam, Anil | Gremeaux, Vincent | Meyer, Philippe | Juneau, Martin | Bosquet, Laurent; International audience; ''High-intensity interval training (HIIT) is frequently used in sports training. The effects on cardiorespiratory and muscle systems have led scientists to consider its application in the field of cardiovascular diseases. The objective of this review is to report the effects and interest of HIIT in patients with coronary artery disease (CAD) and heart failure (HF), as well as in persons with high cardiovascular risk. A non-systematic review of the literature in the MEDLINE database using keywords 'exercise', 'high-intensity interval training', 'interval training'…
