Interventions
This is a randomized, two-arm clinical study in trained and untrained subjects. The study will consist of 72 subjects, subdivided into 12 subjects per group. Subjects from the 6 subgroups: trained wit
trained with 40% blood flow restriction (TRFS40%)
strength training with low load (TFBC)
untrained with 60% blood flow restriction (DRFS60%)
untrained with 40% blood flow restriction (DRFS40%)
untrained strength training with low load (DFBC). Randomization will be performed using an opaque envelope draw. All volunteers will go to the Kinanthropometry and Human Performance Laboratory of the

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| It is expected that trained and untrained individuals will show differences in hemodynamic and strength prescription parameters, and in body composition through strength training associated with blood flow restriction. This will be achieved using a body composition assessment method employing dual-spectrum X-ray absorptiometry, ultrasound, and strength and hemodynamic measurements, based on the observation of a variation of at least 5% in pre- and post-intervention medications | — |
