Vitamin D deficiency related to physical capacity during cardiac rehabilitation / Olivier Ucay 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. 2-5 Titre : Vitamin D deficiency related to physical capacity during cardiac rehabilitation Type de document : texte imprimé Auteurs : Olivier Ucay ; Marion Pouche ; Thibaut Guiraud ; [et al...] Année de publication : 2017 Article en page(s) : p. 2-5 Langues : Français (fre) Mots-clés : vitamine D  réhabilitation cardiaque Résumé : Background Vitamin D deficiency is a frequent pathology associated with cardiovascular diseases and physical performance. Objective To study the link between 25-hydroxyvitamin D (25OHD) level and physical performance and gain in physical performance after cardiovascular rehabilitation (CVR) with vitamin D deficiency. Methods 25OHD level was assessed in a retrospective cohort of patients admitted for CVR. Data were collected on physical fitness [6-min walk test distance (6MWD) in percentage of predicted, maximal power (Pmax)]. The threshold of vitamin D deficiency was 20ng/ml chosen according to the literature. Results Among the 131 patients included, as compared with those with nondeficiency (n=83; 63%), patients with vitamin D deficiency (n=48, 37%) had lower initial 6MWD (82±18 vs 89±12% predicted, P=0.009) and Pmax (100±58 vs 120±39W, P=0.006). After CVR, this difference was maintained. The improvement in 6MWD and Pmax was significantly lower with deficiency than nondeficiency, for an increase of 11±8% versus 14±9% predicted (P=0.048) and 10±30 versus 32±30W (P=0.00001), respectively. Conclusion Vitamin D deficiency may be associated with impaired physical fitness before CVR and a smaller gain in physical fitness with CVR, probably related to the action of vitamin D on the muscle.

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)

Public ISBD [article]  inAnnals of physical and rehabilitation medicine > Vol. 60, n°1 (January 2017) . - p. 20-26 Titre : Whole-body strength training with Huber Motion Lab and traditional strength training in cardiac rehabilitation: A randomized controlled study Type de document : texte imprimé Auteurs : Thibaut Guiraud ; Marc Labrunée ; Florent Besnier ; [et al...] Année de publication : 2017 Article en page(s) : p. 20-26 Langues : Français (fre) Mots-clés : réhabilitation cardiaque  force  contraction isométrique Résumé : Background Isometric strengthening has been rarely studied in patients with coronary heart disease (CHD), mainly because of possible potential side effects and lack of appropriate and reliable devices. 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.
