The training method with blood flow restriction: perception and critical analysis of the methodological process and its use

Abstract

The objective was to verify the perception, critical and methodological analysis of the technique of blood flow restriction (RFS) by specialist researchers. This was a descriptive cross-sectional study with a qualitative approach, based on discourse analysis on the theme — RFS in the Context of Rehabilitation, during the III International Congress on Health, Sport and Pedagogy of Movement — SINERGIA BRAZIL III. The researchers had a determined speaking time during the debate, with ample discussion after the questions. Discourse analysis was performed from the transcription of the recording. The results indicated the need to adjust the restriction pressure during the training progression; the RFS was considered adequate to treat post-COVID-19 patients through preconditioning at rest; excel in evaluating the risks and benefits before its use; the terminology “RFS” frightens the public that is not familiar with the method; RFS variations are essential for rehabilitation in clinical practice; its applicability must be exacerbated for the general population; there is a need for methodological validation and equipment with lower financial cost; it is envisioned that the most technological and expensive devices are used in laboratories and clinics. It is concluded that there was a convergence among researchers regarding the efficiency of RFS.
