The CT protocol will be held in three sessions per week for 14 weeks. The volume of work is defined by the training section of time and intensity of effort by the heart rate response to exercise.

The construction of own model of periodization to be used complies with the biological principle of interdependence volume vs. intensity, and duration of 14 weeks, proposing a week of recuperative exercises after two weeks of stress, gradually increasing the intensity with respective volume settings. This model is based on the concepts described by Turner et al. that concludes in favor of the organization of training adapted to the reality of the public to be trained.

The strength training protocol was performed in three sessions per week for 14 weeks and divided into three levels.

The initial load set for each exercise was based on the one repetition maximum test (1 RM). Strengthening exercises were performed in two sets of 15 repetitions, using 25% 1RM for hip adductors and abductors, and 50% 1RM for the quadriceps and hamstrings, using ankle weights. Exercises for the trunk were performed in 3 10-second series, increasing the duration when participants were able.

In order to provide care, social interaction, and health education, an educational protocol was conducted. This protocol consisted in interactive presentations of 60 minutes, twice a month for 14 weeks, totaling 7 meetings. The topics addressed pathophysiology of osteoarthritis, and American College of Rheumatology (ACR) recommendations on nutrition, posture, and lifestyle.

The concentration of intermuscular fat tissue will be measured by computed tomography. The images will be obtained through a CT scanner Multislice (Brilliance CT 16-slice, Phillips), located at the University Hospital of San Carlos. The examination will be conducted by experienced personnel under the supervision of a radiologist, developer of this study.

The suggested protocol will provide an image related to the mid-thigh area of both legs. Quantification of intermuscular fat quadriceps muscle will be carried out by a slice thickness of 10 mm corresponding to half the distance between the greater trochanter and the intercondylar notch of the femur. The analyzes of the areas will be manually performed using the software OsiriX., And the area of interest selected by a scan, in accordance with the density of tissue decay rates for quantification of adipose tissue present in cm2.

For body composition analysis as it is used absorptiometry apparatus of X-ray Dual Energy (DXA, Hologic Discovery A, Benford, MA) using the three compartment model (lean mass, adipose tissue and body mineral density ), thus allowing to estimate the total body composition and body segment.

The participant will be placed in the supine position and should remain without moving during the examination. To obtain better image, the subject should not use any type of metal, either as accessories or clothing. The results are transmitted to a connected to the machine computer and the examination of the report will provide data expressed in grams and percentage, are used to analyze data related to adipose tissue (g) Lean Mass (g) of the total composition (g) and percentage arms of adipose tissue (right and left), trunk and legs (right and left), gynoid regions and android beyond the total body composition.

To assess pain, stiffness and physical function will use the questionnaire WOMAC (Western Ontario and McMaster Universities), a self-administered instrument that addresses the impact and restrictions specifically on the quality of life of patients with OA of the lower limbs. It is a questionnaire translated and validated for the Portuguese language. Composed of 24 reported auto issues, based on information in the 72 hours prior to their application, it is divided into three domains: pain, stiffness and physical function. Scoring is done using a Likert scale, wherein each question scored between 0 and 100, distributed as follows: 0 = none; 25 = little; Moderate = 50; = 75 intense and very intense = 100 59. The final score will be determined by the highest score in each area, causing pain, stiffness and physical function considered worse the higher the score achieved.
