Brief summary
Compare the Effect of Different Physical Programs on the Body Composition of Adult Women and Men With a Total Body Fat Percentage ≥ 30 % at the Beginning of the Test or BMI ≥25
Detailed description
Weight loss by exercise can be frequently deceptive. The focus continues to be centred around total body weight and body mass index (BMI), despite the fact that body fat and fat-free mass are the indicators that represent the greatest risk in the comorbidity associated with obesity. Body weight per se cannot be considered to be reliable; however, its quality can be justified, when measured together with the loss in body fat and the maintenance or increase in fat-free mass. The purpose of the study is compare the effect of different physical programs (FA) on the body composition (BC) of adult women with a total body fat percentage ≥ 30 % and adult men with a BMI ≥25 at the beginning of the test. Participants (n=220, women = 110, men = 110) will be recruited through outpatient from private clinics in Cádiz, Andalucía, Spain, as well as through community presentations. Overweight or obese and sedentary women and men will be randomly assigned into three groups according to different levels of AF. 21 of the participants will be assigned to the sedentary control group (METs \<2.9), 20 in a group of moderate AF (METs 3-5.9), and 19 will be assigned to the group of intense AF (METs \>6). For 6 months, all of the women shall follow the same diet with an identical distribution of macronutrients. There will be a weekly check up of weight, fat, body water and muscle mass for all of them.
Interventions
BEHAVIORALeducation and modifying diet
The control group maintains a sedentary lifestyle and is only subjected to follow a hypocaloric diet
BEHAVIORALeducation, modifying diet and physical activity prescription
One group, in addition to fulfilling a hypocaloric diet identical to the control group, is subjected to prescribe moderate physical activity. Other group, in addition to fulfilling a hypocaloric diet identical to the control and moderate group, is subjected to prescribe intense activity.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Changes from baseline BMI. | At baseline (0 years) and followed for 2 years | Baseline mean BMI values will be measured and compared at 3, 6, 12 and 24 months. BMI will be assessed on a monthly basis during nutritional consultation through a Bioelectrical Impedance Analysis method using a Tanita BC-418 Segmental Body Composition Analyser/Scale. |
| Changes from baseline Fatty mass. | At baseline (0 years) and followed for 2 years | Baseline mean Fatty mass values will be measured and compared at 3, 6, 12 and 24 months. Fatty mass will be assessed on a monthly basis during nutritional consultation through a Bioelectrical Impedance Analysis method using a Tanita BC-418 Segmental Body Composition Analyser/Scale. Fatty mass is measured as a percentage. |
| Changes from baseline Free-fatty mass. | At baseline (0 years) and followed for 2 years | Baseline mean Free-fatty mass values will be measured and compared at 3, 6, 12 and 24 months. Free-fatty mass will be assessed on a monthly basis during nutritional consultation through a Bioelectrical Impedance Analysis method using a Tanita BC-418 Segmental Body Composition Analyser/Scale. Fatty mass is measured as a percentage. |
| Changes from baseline Muscular Mass. | At baseline (0 years) and followed for 2 years | Baseline mean Muscular Mass values will be measured and compared at 3, 6, 12 and 24 months. Muscular Mass will be assessed on a monthly basis during nutritional consultation through a Bioelectrical Impedance Analysis method using a Tanita BC-418 Segmental Body Composition Analyser/Scale. Fatty mass is measured as a Kg. |
| Changes from baseline Corporal Water . | At baseline (0 years) and followed for 2 years | Baseline mean Corporal Water values will be measured and compared at 3, 6, 12 and 24 months. Corporal Water will be assessed on a monthly basis during nutritional consultation through a Bioelectrical Impedance Analysis method using a Tanita BC-418 Segmental Body Composition Analyser/Scale. Fatty mass is measured as a Kg. |
| Adherence to dietary pattern will be also measured through personal interview | At baseline (0 years) and followed for 2 years | Participants will be subjected for an intervention based on nutritional (control group) and physical education (two intervention arms) during 24 months. Partial measures will be also taken every week. In the end of the trial, changes in dietary patterns will be measured comparing means differences between baselines, 3, 6, 12 and 24 months. |
| Adherence to physical activity patterns will be also measured through IPAQ (International Physical Activity Questionnaire). | At baseline (0 years) and followed for 2 years | Participants will be subjected for an intervention based on nutritional (control group) and physical education (two intervention arms) during 24 months. Partial measures will be also taken every week. In the end of the trial, changes in physical activity will be measured comparing means differences between baselines, 3, 6, 12 and 24 months. |
