Abstract

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.

Highlights

It has been previously noted that 12% of Paralympic athletes have cardiovascular abnormalities, and 2% are at high risk of sudden death and showing arrhythmogenic cardiomyopathies, among other cardiac diseases [1]
The participants consisted of 10 male Brazilian Paralympic powerlifting athletes with a minimum of 12 months of training (2.5 ± 0.2)
The main findings were that the systolic blood pressure was reduced between 20–50 min press at 95% compared

Summary

Introduction

It has been previously noted that 12% of Paralympic athletes have cardiovascular abnormalities, and 2% are at high risk of sudden death and showing arrhythmogenic cardiomyopathies, among other cardiac diseases [1]. Among the effects of resistance training on the cardiovascular system, post-exercise hypotension has been studied in hypertensive subjects with clinically relevant implications [5,6]. 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. Results: Compared with baseline values, a reduction of 5–9% in systolic blood pressure was observed after 90% and 95%
