Key result
Bench press training at both 90% and 95% 1RM elicited a 5-9% reduction in systolic blood pressure at 20-50 minutes post-exercise in Paralympic powerlifting athletes.
Why the study?
Post-exercise hypotension is of clinical relevance, but the cardiovascular effects of different high-intensity resistance-training sessions in Paralympic powerlifting athletes needed comparison.
Does high-intensity resistance training (90% vs 95% 1RM) reduce post-exercise blood pressure in Paralympic powerlifting athletes?

Does high-intensity resistance training (90% vs 95% 1RM) reduce post-exercise blood pressure in Paralympic powerlifting athletes?
High-intensity resistance training induces a transient post-exercise hypotensive response in elite Paralympic powerlifting athletes.
High-intensity bench press may acutely lower SBP in Paralympic powerlifters; extends post-exercise hypotension evidence to elite athletes with disabilities.
Background and objective: Post-exercise hypotension, the reduction of blood pressure after a bout of exercise, is of great clinical relevance. Resistance exercise training is considered an important contribution to exercise training programs for hypertensive individuals and athletes. In this context, post-exercise hypotension could be clinically relevant because it would maintain blood pressure of hypertensive individuals transiently at lower levels during day-time intervals, when blood pressure is typically at its highest levels. The aim of this study was to compare the post-exercise cardiovascular effects on Paralympic powerlifting athletes of two typical high-intensity resistance-training sessions, using either five sets of five bench press repetitions at 90% 1 repetition maximum (1RM) or five sets of three bench press repetitions at 95% 1RM. Materials and Methods: Ten national-level Paralympic weightlifting athletes (age: 26.1 ± 6.9 years; body mass: 76.8 ± 17.4 kg) completed the two resistance-training sessions, one week apart, in a random order. Results: Compared with baseline values, a reduction of 5–9% in systolic blood pressure was observed after 90% and 95% of 1RM at 20–50 min post-exercise. Furthermore, myocardial oxygen volume and double product were only significantly increased immediately after and 5 min post-exercise, while the heart rate was significantly elevated after the resistance training but decreased to baseline level by 50 min after training for both training conditions. Conclusions: A hypotensive response can be expected in elite Paralympic powerlifting athletes after typical high-intensity type resistance-training sessions.

Paz et al. (2020) conducted an RCT in Paralympic powerlifting athletes (n=10). Bench press training at 90% 1RM vs. Bench press training at 95% 1RM (5 sets of 3 repetitions) was evaluated on Reduction in systolic blood pressure at 20-50 min post-exercise. Bench press training at both 90% and 95% 1RM elicited a 5-9% reduction in systolic blood pressure at 20-50 minutes post-exercise in Paralympic powerlifting athletes.
