Twenty-two women will be randomly assigned to two groups (eccentrically enhanced resistance training and traditional resistance training). Interventions will be conducted in the Department of physical education of federal university of Viçosa. All sessions will be supervised by physical education professors. Follow-up will be done through WhatsApp messages and phone calls. Both groups will have a training frequency of 2 times per week for eight weeks. Eccentrically augmented resistance sessions will be performed on the multi-gym flywheel machine for lower and upper limbs for women in the experimental group. The control group will use machines and free weights. In each training session, 6 to 7 exercises will be performed, with 4 sets of 8-12 repetitions, with a rest between exercises of 1 minute and between sets of 2 minutes. The resistance exercise progression is carried out until the woman, with the same mobilized weight in kg, exceeds the maximum number of repetitions suggested by the researchers. Each resistance exercise session will include 6-7 generic exercises involving small and large muscle groups (leg extension, leg curl, biceps curl, triceps extension, seated row, shoulder flexion, and shoulder raise).

Each participant will undergo an initial and final assessment to measure the muscle strength of the lower extremities. The depressive state will be evaluated with a short version of the Geriatric Depression Scale (GDS), validated in Brazil. The physical function will be evaluated with the Test Timed Up and Go (TUG) and Short Physical Performance Battery (SPPB). In addition, executive function will be evaluated with the Victoria Stroop test. Work memory, Digit span forward, Backward and Cognitive flexibility with Trail marking test (Trail A and Trail B).

The Brazilian version of WHOQOL-Bref will be used to assess quality of life. To evaluate the maximum isometric voluntary contraction (MIVC) of the lower extremities, a load cell or extensiometric cell (MK®, model CSL / ZL-1 T, MK Controle, Brazil) with a sampling frequency of 1000 Hz will be used. To perform the 1RM test, the knee extension exercise is performed on a BH fitness® Nevada Pro-t extension machine. The evaluation of lower limb muscular strength will be performed with the same knee extension machine used in training sessions, starting from the same initial position (90o knee flexion) and reaching. Body composition is assessed using a dual-energy x-ray absorptiometry (DXA) full-body scan (GE Healthcare Lunar Prodigy Advance DXA System, software version 13.31). A minimus® III aneroid sphygmomanometer with a maximum error of +/- 3 mmHg will be used. Systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean blood pressure (MBP) are calculated. MBP is obtained with the following mathematical operation: PAD + PAD + PAS / 3. To measure HRR, women are asked to sit for 3 minutes. After that moment, this variable will be taken manually in the radial or carotid pulse of the right side for 60 seconds. The perimeter of the abdomen is measured with a metal tape with the subject's feet, at a midpoint between the lower costal margin and the iliac crest, at the end of a normal expiration.

The risk of falling will be evaluated with the Falls Efficacy Scale-International (FES-I).
