Brief Summary

Android obesity contributes, via insulin resistance and endothelial dysfunction, to the development of cardiovascular atherosclerosis. It leads to poor quality of life. It is often associated with metabolic syndrome which includes, whatever the definitions used (National Education Cholesterol Program, NECP / Adult Treatment Panel III, ATP III or International Diabetes Federation, IDF), an increased waist measurement, an arterial high blood pressure and disorders of the glucide and lipid metabolism. The treatment of the current "epidemic" of obesity and metabolic syndrome in France (12.4 % of obese and 14 % of subjects with metabolic syndrome) thus requires new therapeutic approaches.

A well-balanced diet and a daily physical activity are the indispensable requirements for the treatment of obesity and metabolic syndrome. It is possible to associate it to pharmacological agents, but the results are often partial and transient. Preliminary data suggest that leucine or arginine supplementation could facilitate the loss of fat mass. Moreover, the physical exercise has also demonstrated benefits.

Sessions of physical reconditioning (aerobic work + muscular intensification) associated with a program of specific nutritional supplementation by a mixture of Leucine and Arginine (in the daytime) could improve the treatment of obese subjects affected by metabolic syndrome.

• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: NONE

Study Groups

S: Nutritional Supplementation alone

Specific nutritional supplementation for six months by 30g per day of a mixture of amino acids (21 g of L-Leucine and 9 g of L-arginine), to distribute during each of the 3 main meals.

Group Type: ACTIVE_COMPARATOR

L-Leucine and L-arginine

Intervention Type: DIETARY_SUPPLEMENT

Specific nutritional supplementation for six months by 30g per day of a mixture of amino acids (21 g L-Leucine and 9 g of L-arginine), to be distributed during each of the 3 main meals.

A: Physical Reconditioning alone

Physical reconditioning sessions led by a trainer three times a week for 6 months.

Group Type: ACTIVE_COMPARATOR

Physical Reconditioning by a trainer

Intervention Type: OTHER

Physical reconditioning sessions begin with a warm-up for five minutes for the type of effort made, and then correspond to a sporting course composed of elements of strength training and / or aerobic exercises and will be completed by a return to simple stretching and general advice on managing their physical life. The duration of each session will be 45 minutes at the beginning of the protocol and then gradually increased over time to achieve 1:30 of total physical activity at the end of protocol.

AS: Physical Reconditioning + Nutritional Supplementation

Association for six months of a specific nutritional supplementation by 21 g of L-Leucine and 9 g of L-arginine per day (to distribute during each of the 3 main meals) and of physical reconditioning sessions three times a week.

Group Type: ACTIVE_COMPARATOR

Physical Reconditioning by a trainer

Intervention Type: OTHER

Physical reconditioning sessions begin with a warm-up for five minutes for the type of effort made, and then correspond to a sporting course composed of elements of strength training and / or aerobic exercises and will be completed by a return to simple stretching and general advice on managing their physical life. The duration of each session will be 45 minutes at the beginning of the protocol and then gradually increased over time to achieve 1:30 of total physical activity at the end of protocol.

C: Lifestyle counseling

Usual advice given in consultation on the need for a balanced diet and regular physical activity

Group Type: NO_INTERVENTION

No interventions assigned to this group
