Muscle strength
Conditions
Interventions
This is a randomized, parallel-group clinical trial with a superiority structure and single-blind (evaluators). Experimental group: 29 older adults who will perform progressive resistance exercises (P
40 min) for a period of 12 weeks. The training will consist of dynamic exercises of squatting, hip abduction and flexion and plantar flexion. The WBV will begin with 30 seconds of vibration at 30 Hert
other exercises will start at 50% of 1 repetition maximum (1RM) and will progress to 75 to 80% of 1RM. Muscle strength, functional capacity, muscle quality, laboratory tests, body composition and bone

Design outcomes
Primary

| It is expected to find an improvement in the voluntary strength of the Maximum Voluntary Isometric Contraction (MVIC) of the knee extensors measured by the load cell, as well as in the maximum dynamic strength of the knee extensors, assessed one week before and up to one week after the interventions. The results will be compared between groups, and the group that received vibration associated with resistance exercises is expected to show at least a 5% greater improvement compared to the control group that did not receive vibration;It is expected to find an improvement in usual and fast walking speeds over a 4-meter distance, assessed one week before and up to one week after the interventions. The results will be compared between groups, and the group that received vibration associated with resistance exercises is expected to show at least a 5% greater improvement compared to the control group that did not receive vibration;It is expected to find an improvement in functional capacity measured by the Timed Up and Go (TUG) test, assessed one week before and up to one week after the interventions. The results will be compared between groups, and the group that received vibration associated with resistance exercises is expected to show at least a 5% greater improvement compared to the control group that did not receive vibration | — |

| It is expected to find an improvement in laboratory tests measured one week before and up to one week after the interventions, including fasting glucose, glycated hemoglobin, pro-inflammatory markers – TNF, soluble TNF receptor 1 (sTNF-R1), and C-reactive protein (CRP) – and neurotrophin: Brain-Derived Neurotrophic Factor (BDNF). The results will be compared between groups, and the group that received vibration associated with resistance exercises is expected to show at least a 5% greater improvement in the measured parameters compared to the control group that did not receive vibration;It is expected to find an improvement in functional capacity measured by the Bipodal Static Balance Test, assessed one week before and up to one week after the interventions, in three positions held for 10 seconds each with eyes open: standing with feet together, standing with one foot partially in front, and standing with one foot fully in front. The results will be compared between groups, and the group that received vibration associated with resistance exercises is expected to show at least a 5% greater improvement compared to the control group that did not receive vibration;It is expected to find an improvement in functional capacity measured by the Five Times Sit-to-Stand Test (FTSST), assessed one week before and up to one week after the interventions. The results will be compared between groups, and the group that received vibration associated with resistance exercises is expected to show at least a 5% greater improvement compared to the control group that did not receive vibration;It is expected to find an improvement in bilateral handgrip strength, measured with a hand dynamometer one week before and up to one week after the interventions. The results will be compared between groups, and the group that received vibration associated with resistance exercises is expected to show at least a 5% greater improvement compared to the control group that did not receive vibration;It i | — |
