Inclusion criteria
Inclusion criteria: Age over 65 years; diagnosis of osteoarthritis of the knee using the criteria for osteoarthritis of the knee of the American College of Rheumatology (ACR, 1986) or to have grade II or III knee osteoarthritis of the Kelgren and Lawrence (KL) scale; walking independently, without support device; being for at least six months without practicing resisted physical exercise; and do not present as follows: any congenital, traumatic, infectious or deformity abnormality following injury to the knee joint that may have contributed to the development of secondary OA; inflammatory arthritis (e.g., Rheumatoid Arthritis); grade IV knee osteoarthritis on the KL scale; knee flexion deformity greater than 15 degrees; inability to walk or walk with the aid of devices; neurological problems; neuromuscular disease or injury; surgery on the knee (s) in the last year; corticosteroid injection in the last three months; uncontrolled hypertension (> 150/90 mmHg); myocardial infarction in the last six months; unstable cardiovascular disease; conditions that may be exacerbated by the protocol (e.g., unstable angina); fractures within the six-month period; present painful changes in the hips and / or ankles and / or pain in the lower back; or severe comorbidity that limits participation in the study. Clinical guidelines established by the ACR include having knee pain on most days of the month and at least 3 of the following 6 criteria: age 50 and older, joint stiffness lasting 30 minutes, crepitation, bone sensitivity, bone augmentation, and heat palpable.
Exclusion criteria
Exclusion criteria: Not participating in one of the sessions; Any limitation that impedes the continuity of the participant in the study; Participants with BMI> 30 kg / m2 (minimize artifact at EMG).

Primary
| Measure | Time frame |
|---|---|
| Compare between elderly women with and without OAJ, during leg press exercise performed at two speeds (slow and as fast as possible), the behavior: From the changes in the mean velocity and average power propulsive of the concentric phase between the two repetitions of beginning and those of the end of the series;;Compare between elderly women with and without OAJ, during leg press exercise performed at two speeds (slow and as fast as possible), the behavior: Muscle activation in both the propulsive and braking phases (vastus lateralis and biceps femoris);;Compare between elderly women with and without OAJ, during leg press exercise performed at two speeds (slow and as fast as possible), the behavior: Changes in concentric time, propulsive time and relative propulsive time;;Compare between elderly women with and without OAJ, during leg press exercise performed at two speeds (slow and as fast as possible), the behavior: Propulsive impulse of the right, left and total limbs;;Compare between elderly women with and without OAJ, during leg press exercise performed at two speeds (slow and as fast as possible), the behavior: Isometric strength and muscle activation;;Compare between elderly women with and without OAJ, during leg press exercise performed at two speeds (slow and as fast as possible), the behavior: From the subjective perception of effort at the end of the series. | — |
