Abstract
The aging process is accompanied by physical, behavioral, and cognitive declines, which produce a great impact on the independency and functionality of the elderly, especially in those individuals with degenerative diseases like Parkinson disease (PD). Muscle weakness is one of the major causes of the decreased functionality on this population as it diminishes mobility and balance, alters the gait pattern, increasing the risk of falls. Muscle weakness is produced by both muscle tissue loss (i.e. sarcopenia) and neural changes (i.e. neural apoptosis). Even though strength training (ST) seems to have a positive impact in the quality of life of healthy elderly individuals and ones with PD, training regimens that impose greater coordinative and motor control demands may have a higher potential to enhance the functionality of this population. In this regard, resistance training performed on instability platforms (IST) seems to be an attractive alternative due to the high proprioceptive overload, and motor control required to perform the training exercises. However, to the best of our knowledge, there are no reports in the literature comparing the functional and neuromuscular adaptations produced by ST and IST. Thus, the purpose of this study is to compare the functional and neuromuscular adaptations produced by ST and IST in healthy and PD elderly. In order to test this hypothesis, 90 old individuals (45 healthy and 45 with PD) will be divided into three groups (i.e. control, ST, and IST). Intervention groups will train for 12 weeks. Maximum dynamic and isometric muscle strength, recruitment and de-recruitment of the motor units, activation deficit and reciprocal and pre-synaptic inhibition will be evaluated pre- and post-intervention.
