Body composition in metabolic syndrome: Proposal of a protocol for a randomized clinical trial evaluating the effect of whole-body vibration exercise

Introduction: Metabolic syndrome (MetS) is characterized by
a group of cardiovascular risk factors, such as hypertension,
hyperglycemia, hypercholesterolemia, low high-density cholesterol
and increased abdominal fat. Over the years, changes
in body composition occur, with accelerated loss of lean mass
and increased fat mass, favoring cardiometabolic disorders.
A strong relationship exists between physical inactivity and
the presence of multiple risk factors for MetS. Thus, physical
exercise has been recommended for the prevention of cardiovascular,
chronic and MetS diseases. Whole-body vibration
(WBV) exercise can be considered to be an exercise modality
that benefits the muscular strength and cardiovascular health
of elderly, sick and healthy people. Individuals with MetS
are unmotivated to perform physical exercise regularly and,
therefore, new approaches to intervention for this population
are desirable. Objectives: The aim of this study is to present
a protocol to verify the effect of WBV exercise on the body
composition of MetS individuals. Methods: Randomized controlled
trial with MetS individuals that will be allocated to an
intervention group (WBVG) and a control group (CG). Participants
will be placed barefoot on the base of a side alternating
vibrating platform, with 130º knee flexion. Individuals (WBVG
and CG) will perform the protocol for 12 weeks, twice a week.
The CG subjects will perform the exercises at 5Hz throughout
the intervention and those from the WBVG will perform the
5Hz exercises in the first session, adding 1Hz per session, ending
the protocol at 16Hz. The body composition will be evaluated
before and after the protocol using bioelectrical impedance
analysis. Discussion: Studies involving WBV exercise have
shown improvement in composition in individuals with
different conditions (healthy and unhealthy). Conclusion: The
proposed protocol will permit the acquisition of findings that
will be relevant in the evaluation of the effect of the WBV on
the body composition of MetS individuals due to its ease of
realization, low cost and safety.
