About

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)

Enrollment: 18 estimated patients

Sex: All

Ages: 65 to 80 years old

18 participants in 2 patient groups

Blood flow restriction

Experimental group

Description:

An exercise protocol will be applied to work on lower limb strength in extension, with the application of BFR, with two 30-minute sessions per week for four weeks. The exercise protocol, based on previous studies in older adults, will consist of three exercises: climbing on a step, knee extension from a seated position and sitting down and getting up from a chair.

Treatment:

Other: Blood flow restriction training

No intervention

No Intervention group

Description:

Patients included in the control group will not receive any intervention, maintaining their activities of daily living in the same way as before the study.
