Effects of an exercise training program on balance, muscle strength and quality of life among community-dwelling women from Sao Carlos Health Family Program area

INTERVENTION: The participants will carry out an exercise training program that will be supervised by a physical therapist, two days per week for 12 weeks, 60 minutes each session. They will be divided into four small groups according to their own schedule preferences. Each training session will consist of stretching exercises, 4 ankle and knee muscle strengthening exercises at an intensity of 60‐70% of 1 repetition maximum (2 sets of 10 repetitions ) and balance training. Static balance training will be performed through simple and double‐tasks at stand on one leg, their heels and their tiptoes and tandem position. Dynamic balance training will be performed through lower support base walking. It will be included ludic activities looking for great adherence. Each session will be accompanied by music. CONDITION: Risk factor for falls in elderly PRIMARY OUTCOME: Isometric and isokinetic evaluation for the ankle plantar flexors and dorsiflexors and knee extensors and flexors will be assessed using a BIODEX 2 isokinetic dynamometer. Posturographic analyzes will be assessed using a stable force platform BERTEC CORPORATION. The variables related to COP (center of pressure) will be area oscillation, antero‐posterior (AP) and medio‐lateral (ML) displacement amplitude, AP and ML displacement velocity, AP and ML oscillation frequency in bipodal stance, unipodal stance an tandem position. SECONDARY OUTCOME: Functional balance will be assessed through Timed Up e Go Test and Berg Balance Scale. Quality of life will be measured using the abbreviated Brazilian version of ; the World Health Organization Quality of Live (WHOQOL‐bref) questionnaire INCLUSION CRITERIA: community dwelling women, 60 years old or older,
