Vibration; Exposure clinical trials

Effectiveness of Focal Vibration and Blood Flow Restriction Within a Multicomponent Exercise Programme.

Sarcopenia can occur or increase due to sedentary lifestyles, physical inactivity or chronic endocrine and inflammatory disorders, this pathology is much more frequent in older people due to the added risk factors and the fact that the physiological ageing process generates a pro-inflammatory situation and an alteration in the synthesis of hormones and myokines, it has been observed that the loss of strength causes functional deterioration and a significant increase in the person's dependence, reduces their functional status and quality of life, and may increase the risk of falls, thereby increasing mortality. Blood flow restriction (BRR) and focal vibration (FV), which aim to achieve muscular hypertrophy without the need to use high loads or intensities, VF or BFR brings improvements to elderly people with sarcopnoea. The hipotesis of this study is the addition of BFR or VF techniques to training results in greater improvements in circulating myokine concentrations and functional tests than not adding it. This study has the objective to determinate whether biochemical markers in serology are able to correlate with improvements in strength, also to study whether the plasma levels of apelin, myomyostatin and lL6 are modified with entraining, to determine whether plasma levels of apelin, myomyostatin and lL6 are further increased by training associated with VF and/or BFR and evaluate the effectiveness of different interventions in improving functional tests. The methodology of the study is a single-blind, randomised, clinical trial will be conducted. The study population is people over 65 years of age, sedentary, with functional independence and with a state of health that allows them to carry out physical activity. The study is planned as a pilot study and will consist of 30 subjects distributed in: 10 people in the control group (CG), 10 in the experimental vibration group (GE-V) and 10 in the experimental group with restriction (GE-R). The variables to be measured are anthropometric variables, biochemical markers, variables of neuromuscular function, information about fragility and independence, an functionality. The intervention will be a training in the control group, the FV and BFR groups will be 3 times a week, with a warm-up, a main block with aerobic work, strength work and training and coordination work, and finally a return to calm, in the experimental groups the strength work will be carried out with these instruments.
