| Expected Outcome 1: It was expected to find that creatine supplementation could increase muscle performance and improve muscle adaptations to the BFR paradigm. It was further expected that when evaluated for a single set performed to concentric failure at 30% of 1RM, the maximum number of repetitions performed in the BFR creatine group would be significantly greater than the BFR placebo or TRAD groups at 8 weeks;Outcome Found 1: Through the method used (BFR) and creatine supplementation, these findings are in agreement with our initial hypothesis that increased phosphocreatine stores may be related to increased work capacity in the BFR paradigm, which also may be related to increased muscle hypertrophy response. It was observed for the first time that 8 weeks of creatine supplementation during training with BFR increased training volume load (VLT) compared to placebo with BFR. On some variables, such as repetitions to failure at 30% 1RM, the BFR creatine-supplemented group performed better than the BFR placebo, TRAD placebo, and the TRAD creatine-supplemented group. Regarding muscle thickness response, creatine supplementation promoted additional increases in muscle thickness in both the TRAD and BFR paradigms compared to their placebo counterparts. It was observed that 8 weeks of TRAD increased biceps muscle thickness by 9.5% (versus pre-exercise condition), which is similar to previous literature data, compared to the BFR-PL model = 9.1%. Creatine supplementation resulted in a 17% increase in muscle thickness after 8 weeks, indicating the effectiveness of creatine when associated with the TRAD paradigm for hypertrophy purposes, as well as increases in muscle thickness (BFR-CR = 12.7%). when associated with the BFR model. Therefore, it was observed that creatine supplementation can be considered anabolic for BFR and TRAD, and ergogenic for BFR in our experimental settings | — |

| Expected Outcome 2: Increases in total body mass and changes in body composition were expected, especially in groups involving creatine supplementation;Outcome Found 2: An increase of ~1.4 kg in total body mass and lean body mass was observed in the creatine groups between baseline (pre) and week 2. These findings are comparable to other studies in the literature that reported increases in body mass and total body water | — |
