Influence of Muscle Strength on the Energy Cost of Walking in Obese Subjects
NCT ID: NCT01794377 Phase: NA Status: COMPLETED Enrollment: 59 Completion: 2013-12
Conditions
Obesity
Interventions
30 minutes of high intensity training, 40 of an endurance training
Summary
The purpose of this study is to evaluate the efficacy of 2 physical exercise training programs, with a supplementation in fruits and vegetables, on energy cost of walking. 60 subjects will be randomized into 2 groups. The first program will be consist of an interval strength training for 30 min on bicycle ergometer (which include strengthening exercises in an high intensity interval training). The second program will be conducted at a relatively low intensity of effort, corresponding to 50% of oxygen uptake (VO2) peak measured by indirect calorimetry. All subjects will receive a free supplement of 5 fruits and vegetables per day during all the intervention. The intervention will last 9 months in total : 5 month at the hospital fallow by 4 month at home.
Primary Outcome
Energy cost of walking, expressed in Joules per kilogram per meter (J/kg/m).
