Acute effects of aerobic running on blood pressure In young normotens adults

Abstract

RESUMOO objetivo do presente estudo foi investigar o efeito hipotensivo induzido pela corrida aeróbica em jovens adultos. Trinta e um indivíduos (18 mulheres e 13 homens) foram submetidos a uma avaliação antropométrica e o protocolo de corrida proposto em uma esteira ergométrica durante 40 min entre 60 a 70% da frequência cardíaca de reserva. Realizaram-se medidas da pressão arterial sistólica (PAS) e pressão arterial diastólica (PAD) que posteriormente foram comparados antes e ao final do protocolo de corrida através do teste t de Student para as variáveis dependentes. Todos os testes foram assumidos com α = 0,05. Em comparação com a PAS antes (127,1 ± 11,5 mmHg) e após (119,9 ± 10,2 mmHg) a corrida, os resultados obtidos evidenciaram uma diminuição da pressão arterial sistólica, o qual resultou uma diferença média de -7,2 ± 6,2 mmHg, demonstrando uma diferença significativa (p = 0,00001). Entretanto, na PAD antes (73,6 ± 8,6 mmHg) e após (72,5 ± 7,8 mmHg) não demonstrou uma diferença significativa (p = 0,36) como efeito agudo na diminuição após a corrida. Portanto, conclui-se que a corrida em moderada intensidade e longa duração pode ser auxiliado no tratamento não farmacológico da hipertensão arterial e como melhoria na saúde cardiovascular.

ABSTRACTThe aim of the present study was to investigate the acute effects of blood pressure induced by moderate intensity aerobic exercise in young adults. Thirty-one individuals (18 women and 13 men) were submitted an anthropometric evaluation and a 40-min running protocol between 60% and 70% of the reserve heart rate. Hemodynamic measurements, systolic blood pressure (SBP) and diastolic blood pressure (DBP) were carried out before and after the running protocol through Student's ttest for the dependent variables. All tests assumed α = 0.05. Significant differences were recorded between SBP before (127.1 ± 11.5 mmHg) and after (119.9 ± 10.2 mmHg) the running protocol. The results showed a decrease in systolic blood pressure, which resulted in a mean difference of -7.2 ± 6.2 mmHg, demonstrating a significant difference (p = 0.00001). However, in the DBP before (73.6 ± 8.6 mmHg) and after (72.5 ± 7.8 mmHg) no showing a significant difference (p = 0.36) as an acute effect on the decrease the running protocol. In conclusion, that moderate intensity and long duration running exercise can be aided in the non-pharmacological treatment of arterial hypertension and as an improvement in cardiovascular health.

Acute effect of benchmarck crosstrainig associated with physiological parameters and mental skills according to performance

“…There was a significant increase in systolic blood pressure and a decrease in diastolic blood pressure. Due to the increase in the SNS and the need to increase cardiac output to perform the task that involves large muscle groups and oxygen demand, much research has been done in the literature about physical exercises and their impact on the physiological mechanisms that regulate blood pressure, such as, baroreflex, autonomic actions on heart rate, stroke volume, peripheral vascular resistance, cardiac output, due to changes in cardiac muscle contraction, with a resulting increase in systemic vascular conductance with the possibility of extending this reduction for up to 24 hours (Materko et al, 2020).…”

Reality and Virtual: Hemodynamic Variables and Rating of Perceived Exertion Between Dance Sessions and Active Videogame Just Dance in Women

“…that the virtual and real sessions contribute to the BP efficiently in the control of health extrapolating clinical improvements in a nonpharmacological way. [37][38][39] It has been suggested in similar studies that AVGs, performed in an acute manner, have the potential to favor an energy expenditure similar to traditional forms of exercise, 10 and may even comply with the requirements of the American College of Sports Medicine for physical activity. 15 Thus, it can be seen that exergames can be a dynamic physical exercise, close to the energy expenditure of the various sports modalities or even higher because it presents significant involvement of the arms in the dance routines, or even requires a greater concentration in performing the exercises.…”
