Post-exercise hypotension of normotensive young men through track running sessions

Abstract

INTRODUCTION: After a single session of physical exercise the blood pressure is reduced (post-exercise hypotension, PHE) and it has been considered as a non-pharmacological mechanism to control the blood pressure. When the exercise is performed since youth it can prevent or avoid hypertension. However, it is important to consider studies with clear practical applications to optimize its reproducibility on a daily basis. OBJECTIVE: Analyze the PEH of normotensive and physically active young men after two track running sessions (maximum and submaximal). METHODS: Participated in this study 62 physically active young men (23.3 ± 4.2 years old; 75.5 ± 9.8 kg; 177.7 ± 5.5 cm; 12.0 ± 4.6% body fatF; 52.4 ± 4.0 mL.kg-1.min-1oxygen uptake), which performed a maximum laboratory exercise test for determination of maximal oxygen uptake (VO2max - aerobic power) and subsequently three randomly running sessions (maximum - T1600; submaximal - T20; control - CON), with 48h interval between themselves. Blood pressure (BP) was measured each 15min during a 60 min period after sessions. RESULTS: Both the maximum and the submaximal exercise lead to PEH. The post-exercise values of systolic blood pressure and diastolic blood pressure differed from resting value in session T20 (p<0.05). The same pattern occurred after T1600 (p<0.05), evidenced from 30th minute post-exercise. The CON did not result in PEH. The magnitude of decay for the mean BP at the 45th after maximum exercise was higher than the other sessions (p<0.05). CONCLUSION: We concluded that both maximum and submaximal exercises, performed on a track running condition, caused PEH in young normotensive and physically active men.

Fractionated Concurrent Exercise throughout the Day Does Not Promote Acute Blood Pressure Benefits in Hypertensive Middle-aged Women

“…Post-exercise hypotension is termed by the post-exercise period in which are registered lower BP values than those measured in the pre-exercise or in a control day ( 8 , 9 ). This phenomenon has great clinical relevance ( 10 – 12 ) and has been shown for normotensive ( 13 ), pre-hypertensive ( 14 ), and hypertensive ( 15 ) individuals, and it can be observed during the 24 h following the exercise ( 14 , 16 ). These BP decay ranged approximately −3.5/−2.5 mmHg after aerobic exercise (AE) and −1.8/−3.2 mmHg after dynamic resistance exercise (RE) ( 6 ), and the most important, it is enough to decrease by 4% of overall risk of mortality caused by coronary diseases ( 17 ).…”

Influência do polimorfismo I/D do gene da eca na HPE de jovens normotensos

“…resultado corrobora os achados de Lizardo et al 19 , 28 verificaram HPE tanto para a PAS, quanto para a PAD, após sessões de corrida máxima e submáxima em jovens normotensos e fisicamente ativos.…”

“…8 e Pardono et al 28 verificaram HPE após sessões máxima e submáxima, em jovens normotensos, sendo que Pardono 8 também observou que os indivíduos carreadores do alelo "I", para o polimorfismo I/D no gene da ECA, obtiveram melhor resposta hipotensora quando comparados àqueles carreadores do alelo "D". Esta influência genética também foi evidenciada no presente estudo (Tabela 4), no qual a AAC da PAD pós-exercício sofreu influência da característica genotípica dos voluntários, sendo evidenciado melhor resposta hipotensora para os indivíduos carreadores do alelo "I" (Figura 2).…”

The acute hypotensive effect of resistance training performed with machines vs free weights in normotensive men

“…In regarding to population investigated, post-exercise hypotensive effects are more pronounced in individuals with hypertension compared with those with normal blood pressure 7 . However, it is necessary to develop studies with normotensive and healthy persons to investigate the influence of different types of exercises on the acute hypotensive response without the influence of aging and related pathologies 12 . Additionally, it could be assumed that alterations in post-exercise blood pressure observed in healthy individuals, would be at least as beneficial in subjects with high blood pressure 7 .…”
