Resumo: Introdução: a necessidade de reposição ao máximo das perdas hídricas tornou-se estabelecida e difundida nos consensos internacionais. Entretanto, permanece pouco compreendida a influência da reposição quando administrada, igualmente, durante e após o exercício sobre parâmetros cardiorrespiratórios. Objetivo: analisar os efeitos da reposição hidroeletrolítica na frequência cardíaca (FC), pressão arterial sistólica (PAS), pressão arterial diastólica (PAD), saturação parcial de oxigênio (SpO 2 ) e frequência respiratória (f) de jovens durante e após um exercício de longa duração. Métodos: 31 jovens (21,55 ± 1,89 anos) realizaram três visitas ao laboratório (intervalo de 48 horas entre elas), sendo na primeira aplicado um teste incremental, para determinação da carga utilizada nas visitas seguintes, e nas duas últimas, denominadas protocolo controle (PC) e protocolo experimental (PE), os sujeitos foram submetidos a 10 min de repouso supino, 90 min de exercício em esteira ergométrica (60% do VO 2pico ) e 60 min de repouso supino. No PC não houve hidratação e no PE houve ingestão de solução isotônica. Os parâmetros FC, PAS, PAD, SpO 2 e f foram mensurados no final do repouso; nos minutos 30, 60 e 90 do exercício, com exceção da f; e nos minutos 1, 3, 5, 7, 10, 20, 30, 40, 50 e 60 pós-exercício. Foi aplicado o teste t de Student ou teste de Mann-Whitney e ANOVA para medidas repetidas ou teste de Friedman seguidos de testes post hoc, com p < 0,05. Resultados: a solução hidroeletrolítica proporcionou manutenção da PAS e da PAD, e menor incremento da FC durante o exercício; e promoveu retorno mais rápido da FC e conservou PAD, SpO 2 , PAS (a partir do 5º min) e f (a partir do 30º min) no período de recuperação. Conclusão: o protocolo de hidratação influenciou parâmetros cardiorrespiratórios de jovens durante e após a realização de atividade física submáxima de intensidade constante e longa duração.

Effects of fluid replacement on cardiorespiratory parameters in exercise and recoveryAbstract: Background: The replacement required of water waste is recognized and established in an international consensus. However, the influence of the replacement in cardiorespiratory parameters, especially when administered during and after physical activity, remains poorly understood. Objective: To analyze the effects of fluid replacement in heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), partial oxygen saturation (SpO2) and respiratory rate (f) of the youngsters during and after a long-term exercise. Methods: 31 individuals (21.55 ± 1.89 years old) performed three visits in the laboratory (48 hours among them), at first an incremental test was applied to determine the load used during subsequent visits. In the last two, called control protocol (CP) and the experimental protocol (EP), the subjects were undergone to a 10 min of supine rest, 90 min of treadmill exercise (60% of VO...

“…Most HRR-related studies lead to prognosis, and it has been found that attenuated HRR response is related to increased mortality [12][13][14][15] . Studies have primarily chosen HRR1 (heart rate recovery at the end of the first minute post peak exercise, etc) as a predictor, although some have used HRR2 6,9,12) or HRR5 14) . For "apparently healthy subjects," the cutoff point for HRR1 in previous published papers was 12 beats per minute (bpm) with a recovery cool-down walk 15) , or 18 bpm without a recovery cool-down walk 8) .…”

“…The value in research of this particular population of obese people with PCA is that coronary risk factors (i.e., obesity, aging, or hypertension) have not yet damaged their coronary vessels. Two studies showed that HRR successfully predicts that mortality is independent of the severity at angiography 8,9) when using a study design that mixed angiographically patent subjects with patients having coronary artery disease (CAD). The results suggested that people with CAD are more likely to have abnormal HRR.…”

Abstract.[Purpose] Heart rate recovery (HRR), a recently recognized cardiovascular risk factor, is predominantly modulated by reactivation of vagal tone after exercise stops. Obesity causes autonomic dysfunction that may result in reduced HRR following exercise. We sought to determine whether obesity is associated with reduced HRR and possible influential factors.[Methods] Analyses were based on 62 men who had confirmed angiographically patent coronary arteries (PCA) and had reached 85% of their age-predicted maximal heart rate (MHR). Subjects were divided into 3 groups according to their body mass index (BMI): NOR (BMI<24), OW (24≤BMI<27), and OB (BMI≥27) as recommended by the Ministry of Health, Taiwan. HRR were defined as the difference between the MHR obtained during exercise and the HR at 1, 3, and 5 minutes after exercise stopped. After separating subjects into higher and lower HRR subgroups using the median as a cutoff point, logistical analysis was performed to provide odds ratios (OR) and 95% confidence intervals (CI) of independent variables related to HRR. [Results] Subjects reached similar absolute work loads, but NOR reached a higher percentage of age-predicted MHR when compared with OW and OB. No significant difference was found in HRR after 1 minute. In logistic regression analyses, the higher HRR1 was mostly associated with a lower resting HR (OR 0.95, CI 0.91-0.98), and this was also found for HRR after 3 and 5 minutes.[Conclusion] There was no difference in HRR with different degrees of BMI in subjects with PCA. Resting HR was probably the most influential factor contributing to HRR.

“…In contrast, the rapid decline in heart rate after the cessation of exercise is theorized to be due to high vagal tone associated with both the cardiorespiratory fitness level of the individual and the intensity of exercise [7]. Studies have shown that heart rate recovery is faster in trained subjects than in untrained subjects [8] Although earlier physiological studies suggested a rapid HR recovery rate after relatively high levels of exercise, is a marker of physical fitness, the usefulness of this variable has not been generally discussed. Studies demonstrate that HR declines monoexponentially after exercise [12] [13].…”

Heart rate recovery: validation and methodologic issues

Abstract: Heart rate at 1 or 2 min of recovery has been validated as a prognostic measurement and should be recorded as part of all treadmill tests. This new measurement does not replace, but is supplemental to, established scores.
