Abstract: Exercise, including resistance exercise with high loads, has positive hemodynamicresponses such as reduced systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), Pressure Product Rate (PPR), and estimated myocardial oxygen volume (MVO2). Caffeine (CA), used to improve performance, tends to interfere with BP and HR. This study aimed to analyze the effects of CAsupplementation on hemodynamic indicators in Paralympic weightlifting (PP). The exercise was performed on 14 male athletes (32.4 8.5 years; 81.7 21.9 kg) for three weeks. Two conditions were evaluated: supplementation with CA Anhydrous 9 mg/kg and with placebo (PL). The adapted bench press was used, with 5 5 at 80% 1RM. Weevaluated BP, HR, PPR, and MVO2, before, after, 5, 10, 20, 30, 40, 50, 60 min, and 24 h later. The CA presented higher absolute values in the pressure indicators than the PL, and after 24 h there was an inversion. The HR was higher in the CA and showed a reduction after 10 min. The PPR and MVO2 in the CA presented absolute values greater than the PL, and 24 h later there was an inversion. There was no hypotensive effect, but the use of CAdidnot present risks related to PPR and MVO2, demonstrating the safe use of this supplement in adapted strength sports.
