Impact des ultrasons diffus combinés au travail musculaire sur plaque vibrante sur la modification de la composition corporelle de femmes modérément obèses

Objectifs

Étudier les effets d’ultrasons diffus appliqués dans la région abdominale combinés au travail musculaire sur plaque vibrante chez des femmes obèses. Cette méthode a pour but d’accélérer la mobilisation de graisse du tissu adipeux abdominal.

Méthodes

40 femmes obèses sédentaires, âgées entre 18 et 55 ans, avec un IMC ≥ 30 kg/m2 et ≤ 40 kg/m2ont été randomisées en 3 groupes. Un groupe témoin (CONTR, n=13), un groupe vibration (VIB, n=16), et un groupe vibration combiné à une ceinture abdominale à ultrasons (VIB+US, n=11).

Résultats

Cette étude exploratoire a montré que le groupe VIB+US a réduit significativement la circonférence abdominale (de 8 %), et la masse grasse totale (de 7 %). Les résultats dans le groupe VIB étaient similaires (réduction de 7 et 5 % respectivement) mais ceux-ci ont été obtenus en 2 fois plus de temps (12 semaines plutôt que 6 semaines).

Conclusion

Cette étude préliminaire montre l’efficacité de cette nouvelle méthode — qui associe une ceinture abdominale à ultrasons diffus à un exercice sur plateforme vibrante — sur la vitesse de déstockage de la masse grasse totale et notamment au niveau abdominal sous-cutané, dont la mobilisation est particulièrement difficile. Ces résultats nécessitent non seulement une confirmation dans un groupe d’obèses plus important et traité plus longtemps, mais aussi l’adjonction de mesures biochimiques, cellulaires et moléculaires afin d’en mieux comprendre les mécanismes sous-jacents.

Effect of diffuse ultrasound combined to muscular work performed on a vibration plateform on body composition in moderately obese women

Abstract

Objectives

To study, in obese subjects, the effect of diffuse ultrasound application in the abdominal area combined to muscular work on a vibrating platform. This dual method aims at accelerating the mobilisation of adipose tissue.

Methods

40 sedentary obese women, 18 to 55 years old, with a BMI ≥30 kg/m2 and ≤40 kg/m2 were randomized into 3 groups. 1) A control group (CONTR, n=13), 2) a vibration group (VIB, n=16), and 3) a vibration + ultrasonic group combined (VIB+US, n=11).

Results

This exploratory study has shown that the group VIB+US has significantly diminished the rate of abdominal circumference reduction (by 8%), the total body fat mobilisation (by 7%). In the the VIB group, similar results were obtained (7 and 5% reduction respectively) but within 12 weeks rather than 6 weeks.

Conclusion

this study indicates the efficiency of a dual treatment associating muscular work on the vibrating plateform to diffuse ultrasounds on the rate of mobilization of total body fat, in particular in the abdominal subcutaneous area, which is generally refractory to mobilization. These results could justify, for well selected patients, the use of this new method, together with others, in the treatment of the android obesity. These very preliminary results require further validations by independent laboratories in a much larger group of obese, with a study of longer duration in different phenotypes of obese, with biochemical, cellular and molecular approaches to better understand the underlying mechanisms.
