Blood Flow Restriction in Older Adults
Sponsor: Universidad Católica San Antonio de Murcia
Summary
Introduction. From the age of 80 onwards, more than 50% of people suffer from sarcopenia. The loss of muscle strength leads to a loss of muscle power, impairing functionality and preventing the correct performance of activities of daily living. Objective. To analyse the efficacy of blood flow restriction in older adult patients by evaluating changes in the variables muscle power and strength, physical condition and functionality of the lower limbs. Material and method. Randomised single-blind clinical study. Thirty-six older adults will be recruited and randomised to the experimental and control groups. The intervention will have a duration of 4 weeks, with 2 weekly sessions. The intervention will consist of an intervention by performing 3 quadriceps strength exercises, with a 40% restriction. The primary variable of the study will be muscle power (Sit To Stand 5 times) and the secondary variables will be muscle strength (dynamometry), physical condition (Timed Up and Go) and functionality and autonomy (Barthel index)

Interventions
Blood flow restriction training
The intensity of the work will be set at around 40% of the maximum intensity that can be executed in a single repetition (1RM). To reach the established intensity, weights, weighted ankle supports and rubber bands of different resistances will be used. Three sets of 8-10 repetitions will be performed with breaks of 1-2 seconds between repetitions and 2-3 minutes between sets. The intensity of the work will be established by applying the rate of perceived exertion. A blood flow restriction device will be used (Akrafit, Valencia, Spain model).
