Descripción detallada
This is a randomized clinical trial study (RCT) with 2 parallel arms. The subjects will be divided in 2 groups with a randomized block technique: Elastic Training Group (ETG) and Machine Training Group (MTG). The subjects will be submitted to a two-week familiarization period and then a sixteen-week of strength training program will be performed twice a week.
This regimen of resistance training in both groups will consist of four exercises for lower limbs and four exercises for upper limbs which will be alternately performed with a one-minute interval between them during familiarization and training periods. Lower limb exercises will consist of: hip extension and abduction, and knee flexion and extension. Upper limb exercises will consist of: bench press, rowing, triceps and high pulley exercise.

|
Change in Muscle Strength
Periodo de tiempo: Change from baseline in muscle strength at 16 weeks.
|
Lower limb muscle strength will be assessed with an isokinetic dynamometer (Biodex System®, model III) and upper limb muscle strength with an isometric dynamometer (Jamar®, Hand Dynamometer).
|
Change from baseline in muscle strength at 16 weeks.
|
Change in Postural Balance
Periodo de tiempo: Change from baseline in postural balance at 16 weeks.
|
The postural balance will be assessed with a three-dimensional (3D) motion analysis system and force plates.
|
Change from baseline in postural balance at 16 weeks.
