Age
60 Years to 75 Years
Inclusion criteria
Inclusion criteria: Elderly between 60 and 75 years of both sexes; hemodynamically stable according to the guidelines of the Brazilian Society of Cardiology (BP 90mmHg x 60mmHg) (Brazilian Society of Cardiology); active in relation to Resistance Training in the minimum six months; able to perform the exercise at 80% of 1RM (1 maximum repetition) in the Scott curl; performing at least ten repetitions of this exercise; having received the second dose of the COVID-19 vaccine.
Exclusion criteria
Exclusion criteria: Elderly people who have a cut-off score of less than 14 in the Mini-Mental State Examination (MMSE); having uncontrolled arterial hypertension; acute or chronic pain in the upper limbs; contraindication to the use of Transcranial Continuous Current Stimulation such as a history of recurrent seizures, tumors or skin infection at the stimulation site and any metallic material implanted in the brain, use of a pacemaker or metallic implant in the head; presenting sequelae of COVID-19 such as fatigue, cardiopulmonary or musculoskeletal disorders.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| It is expected that transcranial stimulation by the active anodic direct current will increase the resistance of the biceps brachii muscle to the process of muscle fatigue in the elderly, measured by comparing the number of repetitions of initial and final muscle contraction. | — |
Secondary
| Measure | Time frame |
|---|---|
| It is expected that active anodic direct current transcranial stimulation will maintain the final cortical excitability measured by the motor evoked potential as close as possible to the initial value.;It is expected that transcranial stimulation by active anodic direct current will decrease the subjective perception of exertion during and after the fatigue protocol.;It is expected that transcranial stimulation by active anodic direct current will decrease the subjective perception of exertion during and after the fatigue protocol. | — |
