Exercise Training Improves Heart Rate Recovery after Exercise in Hypertension

Abstract

This study tested the hypothesis that: 1-the exercise training would improve the heart rate recovery (HRR) decline after maximal exercise test in hypertensive patients and; 2-the exercise training would normalize HRR decline when compared to normotensive individuals. Methods: Sixteen hypertensive patients were consecutively allocated into two groups: Exercise-trained (n = 9, 47±2 years) and untrained (n = 7, 42±3 years). An exercise-trained normotensive group (n = 11, 41±2 years) was also studied. Heart rate was evaluated by electrocardiogram. The autonomic function was evaluated based on heart rate changes on the first and the second min of recovery after the maximal exercise test. Exercise training consisted of three 60-minute exercise sessions/week for 4 months. Results: In hypertensive patients, exercise training significantly increased the HRR decline in the first (-19±2 vs.-34±3 bpm, P = 0.001) and second (-33±3 vs.-49±2 bpm, P = 0.006) minutes after the maximal exercise test. In addition, after exercise training, the initial differences in the HRR decline after exercise between hypertensive patients and normotensive individuals were no longer observed (first minute:-34±3 vs.-29±3 bpm, P = 0.52, and second minute:-49±2 vs.-47±4 bpm, P = 0.99). Conclusion: Hypertension causes a delay in HRR after the maximal exercise test yet the exercise training normalizes HRR during the post-exercise period in hypertensive patients.

A Atividade Física Como Ferramenta De Promoção De Saúde Em Pacientes Hipertensos

“…Adicionalmente, observou-se que a FCR desses pacientes foi normalizada quando comparada àquela de indivíduos normotensos. Esses resultados indicam de maneira significativa um efeito terapêutico do treinamento físico na função autonômica cardíaca desses pacientes hipertensos (Vicente et al, 2019).…”

Cardiac Behavior and Heart Rate Variability in Elderly Hypertensive Individuals during Aerobic Exercise: A Non-Randomized Controlled Study

“…Furthermore, differences in heart rate recovery may vary in elderly hypertensive individuals depending on BP control. Amaro-Vicente et al [37] investigated heart rate recovery in normotensive and hypertensive individuals whose mean age was over 57 years using antihypertensive drugs with controlled and uncontrolled blood pressure. They found that in hypertensive patients, the ideal BP after antihypertensive medication is related to an improvement in sympathetic/vagal balance [38].…”

Comparison of morning versus evening aerobic-exercise training on heart rate recovery in treated hypertensive men: a randomized controlled trial

“…Aerobic-exercise training is recommended for the treatment of hypertension. In addition to decrease blood pressure, aerobic training improves resting cardiovascular autonomic modulation in hypertensives and accelerates HRR after exercise [4]. However, the effects of aerobic training on autonomic control may vary depending on the time of day in which training sessions are performed.…”
