Design outcomes

Primary

MeasureTime frame
To evaluate whether there will be improvement in muscle strength and physical function after the intervention, verified through isokinetic dynamometry for knee flexor and extensor muscles using the Cybex Humac Norm equipment from CSMi, and through the functional tests Short Physical Performance Battery (SPPB) and Timed Up and Go (TUG), with observation of peak torque in newton meter, flexor extensor strength ratio in percentage, Short Physical Performance Battery score from 0 to 12 points, Timed Up and Go time in seconds, and percentage change between baseline and post intervention;To evaluate whether there will be improvement in metabolic and inflammatory profile after the intervention, verified through laboratory blood tests, with observation of absolute values and changes between pre intervention and post intervention for lipid profile, glucose, insulin, glycated hemoglobin, homocysteine, vitamin D, vitamin B9 or folic acid, thyroid stimulating hormone (TSH), triiodothyronine (T3), thyroxine (T4), C reactive protein, and cortisol;To evaluate whether there will be reduction in body fat and increase in lean mass after the intervention, verified through bioelectrical impedance analysis using the InBody R20 equipment from Biospace, with observation of body fat percentage, fat mass in kilograms, skeletal muscle mass in kilograms, body mass index in kilogram per square meter, and percentage variation between pre intervention and post intervention

Secondary

MeasureTime frame
To evaluate whether there will be improvement in spatial and temporal gait parameters after the intervention, verified through the P WALK 2.0 baropodometric platform from BTS Bioengineering, with observation of gait speed in meters per second, stride length in centimeters, plantar contact area in square centimeters, single and double stance times in milliseconds, and gait cycle variability expressed as coefficient of variation in percentage;To evaluate whether there will be improvement in subjective and behavioral indicators related to brain health after the intervention, verified through questionnaires applied to the domains of general health, physical activity using the International Physical Activity Questionnaire (IPAQ), cognition, social interactions, sense of purpose using the Daily Activities and Support Scale (DAS 8) and the Mental Health Continuum Short Form (MHC SF), sleep using the Pittsburgh Sleep Quality Index (PSQI), and nutrition using the Nutritional Risk Screening (NRS 2002), with observation of the raw scores of each instrument and the percentage variation between baseline and post intervention
