Exercise training-induced modification in autonomic nervous system: An update for cardiac patients / Florent Besnier in Annals of physical and rehabilitation medicine, Vol. 60, n°1 (January 2017)

Public ISBD [article]  inAnnals of physical and rehabilitation medicine > Vol. 60, n°1 (January 2017) . - p. 27-35 Titre : Exercise training-induced modification in autonomic nervous system: An update for cardiac patients Type de document : texte imprimé Auteurs : Florent Besnier ; Marc Labrunée ; Atul Pathak ; [et al...] Année de publication : 2017 Article en page(s) : p. 27-35 Langues : Français (fre) Mots-clés : réhabilitation cardiaque  entrainement  maladie cardio-vaxculaire Résumé : Patients with cardiovascular disease show autonomic dysfunction, including sympathetic activation and vagal withdrawal, which leads to fatal events. This review aims to place sympathovagal balance as an essential element to be considered in management for cardiovascular disease patients who benefit from a cardiac rehabilitation program. Many studies showed that exercise training, as non-pharmacologic treatment, plays an important role in enhancing sympathovagal balance and could normalize levels of markers of sympathetic flow measured by microneurography, heart rate variability or plasma catecholamine levels. This alteration positively affects prognosis with cardiovascular disease. In general, cardiac rehabilitation programs include moderate-intensity and continuous aerobic exercise. Other forms of activities such as high-intensity interval training, breathing exercises, relaxation and transcutaneous electrical stimulation can improve sympathovagal balance and should be implemented in cardiac rehabilitation programs. Currently, the exercise training programs in cardiac rehabilitation are individualized to optimize health outcomes. The sports science concept of the heart rate variability (HRV)-vagal index used to manage exercise sessions (for a goal of performance) could be implemented in cardiac rehabilitation to improve cardiovascular fitness and autonomic nervous system function.

Short-term effects of a 3-week interval training program on heart rate variability in chronic heart failure. A randomised controlled trial / Florent Besnier in Annals of physical and rehabilitation medicine, Vol. 62, n°5 (Septembre 2019)

Public ISBD [article]  inAnnals of physical and rehabilitation medicine > Vol. 62, n°5 (Septembre 2019) . - p. 321-328 Titre : Short-term effects of a 3-week interval training program on heart rate variability in chronic heart failure. A randomised controlled trial Type de document : texte imprimé Auteurs : Florent Besnier ; Marc Labrunée ; Lisa Richard ; Florence Faggianelli ; Hélène Kerros ; Laurent Soukarié ; Marc Bousquet ; Jean-Michel Sénard Année de publication : 2019 Article en page(s) : p. 321-328 Note générale : doi.org/10.1016/j.rehab.2019.06.013 Langues : Anglais (eng) Mots-clés : Exercise training  Cardiovascular  Rehabilitation  Chronic heart failure  Parasympathetic  Cardiorespiratory fitness Résumé : Background Exaggerated sympathetic nervous system activity associated with low heart rate variability (HRV) is considered to trigger cardiac arrhythmias and sudden death. Regular exercise training is efficient to improve autonomic balance. Objective We aimed to verify the superiority of high-intensity interval training (HIIT) to enhance HRV, cardiorespiratory fitness and cardiac function as compared with moderate intensity continuous training (MICT) in a short, intense cardiac rehabilitation program. Methods This was a prospective, monocentric, evaluator-blinded, randomised (1:1) study with a parallel two-group design. Overall, 31 individuals with voluntary chronic heart failure (CHF) (left ventricular ejection fraction [LVEF] < 45%) were allocated to MICT (n = 15) or HIIT (n = 16) for a short rehabilitation program (mean [SD] 27 [4] days). Participants underwent 24-hr electrocardiography, echocardiography and a cardiopulmonary exercise test at entry and at the end of the study. Results High-frequency power in normalized units (HFnu%) measured as HRV increased with HIIT (from 21.2% to 26.4%, P < 0.001) but remained unchanged with MICT (from 23.1% to 21.9%, P = 0.444, with a significant intergroup difference, P = 0.003). Resting heart rate (24-hr Holter electrocardiography) decreased significantly for both groups (from 68.2 to 64.6 bpm and 66.0 to 63.5 bpm for MICT and HIIT, respectively, with no intergroup difference, P = 0.578). The 2 groups did not differ in premature ventricular contractions. Improvement in peak oxygen uptake was greater with HIIT than MICT (+ 21% vs. + 5%, P = 0.009). LVEF improved with only HIIT (from 36.2% to 39.5%, P = 0.034). Conclusions In this short rehabilitation program, HIIT was significantly superior to the classical MICT program for enhancing parasympathetic tone and peak oxygen uptake.

Whole-body strength training with Huber Motion Lab and traditional strength training in cardiac rehabilitation: A randomized controlled study / Thibaut Guiraud in Annals of physical and rehabilitation medicine, Vol. 60, n°1 (January 2017)

Objective We aimed to compare 2 different modes of resistance training, an isometric mode with the Huber Motion Lab (HML) and traditional strength training (TST), in CHD patients undergoing a cardiac rehabilitation program. Design We randomly assigned 50 patients to HML or TST. Patients underwent complete blinded evaluation before and after the rehabilitation program, including testing for cardiopulmonary exercise, maximal isometric voluntary contraction, endothelial function and body composition. Results After 4 weeks of training (16 sessions), the groups did not differ in body composition, anthropometric characteristics, or endothelial function. With HML, peak power output (P=0.035), maximal heart rate (P<0.01) and gain of force measured in the chest press position (P<0.02) were greater after versus before training. Conclusion Both protocols appeared to be well tolerated, safe and feasible for these CHD patients. A training protocol involving 6s phases of isometric contractions with 10s of passive recovery on an HML device could be safely implemented in rehabilitation programs for patients with CHD and improve functional outcomes.
