A Multi-component Intervention in Frail Community-dwelling Older People

This study evaluates if a multi-component intervention, respecting the characteristics of frail older person and increasing intensity and challenge of exercises according to frail older person capacity/evolution will induce better functional results than a multi-component intervention specific to lower body. the volunteers will be randomized into experimental group and control group.

The interventions are separated by day (1 to 24) and by weeks (1 to 12). Each session was built to last between 50 and 60 minutes, beginning with a warming up. In the table are described the exercise as well as the support necessary to perform the exercise safely and necessary equipment (accessories). In cases where a minimum load is required the same are also described in the multimodal intervention protocol (load).

In relation to strength training in the multimodal intervention protocol is described how the progression of intensity will be held. Additional to the load progression suggested, the 1 maximal repetition test will be applied every 4 weeks for adjustment of the loads according to strength gain from each volunteer.

The suggested protocol is based on balance exercises and strength but, in a careful manner, were included functional and mobilization exercises to ensure greater diversity.

Multimodal intervention protocol:
