Clinical Trial Summary

Blood flow restriction (RFS) is a widely studied technique that combines low-intensity exercise with vascular occlusion, resulting in muscular benefits. However, its application is challenging due to methodological variations and equipment costs. Tissue Flossing (TF) appears as an affordable alternative, but lacks solid scientific evidence.

Clinical Trial Description

Objectives: to evaluate the intra- and inter-rater reliability of the occlusion pressure generated by TF, investigate the reproducibility of TF application on different days and compare TF with traditional RFS in terms of muscle gains. Methods: the study is divided into two stages: First stage, randomized controlled crossover clinical trial, 80 healthy individuals aged 18 to 30 years old evaluated to determine the reliability of the TF. Participants will follow one of two types of randomization, with exclusions based on health criteria. Assessments include anthropometric characteristics, determination of occlusion pressure (POT), identification of 40% and 80% of POT, flow data and arterial diameter after TF application. Statistical analysis will use the intraclass correlation index (ICC) and specific models for intra- and inter-rater analyses. Second stage, randomized controlled clinical trial with parallel groups, 110 recreational athletes will be evaluated over four weeks. The initial procedures involve anthropometric assessments, POT determination, myotonometry, ultrasound, perceptual scale and 1RM test, applied to both lower limbs. Participants will perform a lower limb training protocol, using RFS and TF on different legs, following myotonometric and perceptual assessments. After training, final assessments will measure the same parameters initially assessed. Statistical analysis will use normality tests, Generalized Mixed Models and effect size analysis in SPSS software, with a significance level of p<0.05. Expected results: This study is expected to provide information on the reliability and reproducibility of TF in generating occlusion pressure. Furthermore, we seek to validate TF by comparing it with traditional RFS in terms of muscle gains. If effective, TF could become an affordable option to promote muscle gains, in different application scenarios. Participants will be duly informed about the procedures and objectives of this study, and after agreeing, they will sign an informed consent form, effectively becoming part of it. In the consent form, participants will be asked if they agree to the use of their data if they choose to withdraw from the study. Participants will also be asked for permission for the research team to share relevant data with people at universities participating in the research or regulatory authorities, where relevant. The study will be sent for consideration and approval to the Research Ethics Committee of FCT/UNESP, Presidente Prudente, SP, Brazil. ;
