Résumé

The study was designed to test the following hypotheses: In patients with severe obesity, a multisite electrostimulation session (m-NMES) will induce higher changes in metabolic, inflammatory and cardiovascular parameters and higher increase in muscle strength during stimulated contractions than conventional unidirectional electrostimulation session (c-NMES). In patients with severe obesity, a six-weeks m-NMES training program will enhance cardiovascular, metabolic and inflammatory parameters.

Détail

Voir le détail Background: Physical activity is known to reduce cardiovascular risk as far as even minor change in lifestyle could occur. In obesity, physical activity programs remain challenging due to multifactorial causes related to body mass such as shortness of breath, traumatological pain or psychosocial causes. Although neuromuscular electrical stimulation training is presently ignored in the management of obesity, this technique may be appropriate and useful for muscle deconditioning in these patients. Furthermore, direct effects of electrostimulation training program on vascular function have been previously reported in spinal cord injury and chronic heart disease, suggesting that improvement in cardiovascular function may be expected. While a promising new technique of multisite electrical stimulation (the Kneehab® system) has been recently commercialized, few study have investigated the acute effects of electrostimulation on vascular function and not any study report the effects of electrical stimulation in obese patients. MAIN OUTCOME OF THE ACUTE PHASE STUDY (1st part):To study the effect of multisite electrical stimulation session (m-NMES) on arterial stiffness as compared to conventional unidirectional electrical stimulation session (c-NMES) in patients with severe obesity. Secondary outcomes of the observational study: 1/ To study the effect of m-NMES on endothelial function, blood pressure, systemic inflammation and metabolic status (fasting glucose and insulin) as well as electrically-induced muscle fatigue as compared with c-NMES in patients with morbid obesity. 2/ To study the profile of responders to electrical stimulation according to body composition, 6-minute walking distance, spontaneous physical activity or susceptibility to tolerate electrical stimulation. Response to electrical stimulation will be assessed by an improvement in arterial stiffness after stimulation, if so. MAIN OUTCOME OF THE INTERVENTIONAL STUDY (2nd part):To study the effect of a multisite electrical stimulation training program (m-NMES) (6 weeks, 30 sessions) on arterial stiffness in patients with severe obesity. Secondary outcomes of the interventional study: To study the effect of m-NMES on endothelial function, blood pressure, systemic inflammation and metabolic status (fasting glucose and insulin) as well as muscle strength, body composition, functional capacity (6-minute walking distance) and spontaneous physical activity, after 15 sessions (3 weeks) and after 30 sessions (6 weeks) of training program. Evaluation of the dose-response to m-NMES training in terms of arterial stiffness and functional capacity. Expected outcomes: Acute change in arterial stiffness and/or endothelial function is expected after one m-NMES session and/or after c-NMES session. M-NMES session is expected to induce higher changes than c-NMES stimulation session on cardiovascular and muscle parameters. Chronic changes in arterial stiffness and/or endothelial function is expected after 6 weeks of m-NMES training. Fermer le détail
