Before the intervention period, the following tests will be applied: SARC-F, Short Physical Performance Battery, hand-grip dynamometry, Geriatric Anxiety Inventory, Geriatric Depression Scale and Pittsburgh Sleep Quality Index.

To carry out the telerehabilitation program, the Google Meet platform will be used in order to provide the synchronous service model. This will occur for a period of 16 weeks, three weekly sessions lasting 50 minutes, (total of 48 sessions). The sessions will be given by physiotherapists and students in their final year of graduation in physiotherapy, which will consist of the following phases: initial rest, warm-up, resistance exercises, stretching exercises, relaxation and final rest.

In addition, in exchange for the warm-up phase, every 12 sessions, the telerehabilitation program also will have an approach through health education, using presentations, digital booklets and direct conversation between therapist and participants. The themes exhibited (importance of physical exercise in the pandemic context, reduction of the risk of falls through changes in the home environment and physiological changes resulting from aging) will intend to make them aware of better lifestyle habits.

Sarcopenia will identify and track by the SARC-F questionnaire, composed of five self-reported questions, based on muscle strength activities, ambulation, rising from a chair, climbing stairs and history of falls, in combination with measurement of the right calf circumference as an indirect assessment of muscle mass.

The total score will obtain by means of the sum of the questions (maximum 2 points for each) and the measurement of calf circumference (women: > 33 cm = 0; ≤ 33cm =10 points). This questionnaire is valid for Portuguese Language since 2016.

Physical performance will be evaluated using the SPPB, a simple tool that can help to track the risk of falls by identifying risk factors related to the assessed domains.

This tool has three domains: static balance, lower limbs strength and gait speed. The total SPPB score is made by adding these three domains and can vary between 0 and 12 points.

Hand grip strength will be assessed using a manual dynamometer (Crown produced by the industrial technique Oswaldo Filizola Ltda) with a capacity of 50 kilograms-force, following the protocol proposed by Robert et al.

During the test, the participant remains seated with the forearms resting on the arms of the chair with wrists in a neutral position and her thumbs facing up. The evaluator assists by holding the base of the dynamometer in the palm of the hand in order to nullify the effect of gravity on the test, while the participant holds the dynamometer. In this way, the patient is asked to press as long and strong as possible or until the pointer stops rising. The test is performed three times in each hand, alternating between them, with an interval of 20 seconds for each attempt. The value recorded regarding strength was the highest among the six measures.
