“…Seguindo este conceito, elevações da modulação parassimpática induz uma estabilidade elétrica cardíaca, ao passo que a atividade simpática elevada aumenta a vulnerabilidade do coração, melhorando assim o comportamento da FC e VFC, e com isso, os riscos de eventos cardiovasculares passam a serem menores [21,22].…”

Introdução: Com o avanço da idade, dentre as modificações nas diversas funcionalidades influenciadas pelo envelhecimento, destacam-se alterações na capacidade funcional e no sistema cardiovascular. Objetivo: Verificar as variáveis cardiovasculares de idosos inseridos em diferentes modalidades físicas. Métodos: 40 idosos, sendo 20 homens e 20 mulheres (68,8 ± 7,0 anos, 77,9 ± 12,6 kg, 1,67 ± 0,09 m e IMC 27,78 ± 4,2 kg/m²), subdivididos em 4 grupos: Grupo Caminhada, Grupo Hidroginástica, Grupo Musculação e Grupo Controle, em que ambos os grupos foram compostos por 5 homens e 5 mulheres. Verificou-se (10 minutos em repouso) a frequência cardíaca, variabilidade da frequência cardíaca, pressão arterial sistólica e diastólica, e o duplo produto. Resultados: Nenhuma diferença significativa entre os dados investigados foi encontrada, demonstrando assim um comportamento igualitário das variáveis cardiovasculares entre os grupos, em patamares adequados e aceitáveis. Conclusão: Não verificamos diferenças no repouso, entre os grupos de exercício e em relação ao controle.Palavras-chave: idosos, variáveis cardiovasculares, modalidades físicas.

Introduction: Different mechanical behaviors in resistance training can result in certain changes in the cardiovascular system. Objective: To verify the acute behavior of the main cardiovascular variables (heart rate, blood pressure, and double product) when performing resistance training with mono and multiarticular exercises. Methods: 10 male subjects participated in the study (26 ± 4 years; 81 ± 6 kg; 1.77 ± 2 m; 23 ± 1 kg / m2). They performed a test and retest for 8RM in the bench press and crucifix exercises on the machine. After the loads were outlined, they performed the intervention with the exercises, initially with a monoarticular activation containing two sets of 12 repetitions with 50% of the load acquired in the 8RM test of each exercise, using an interval of 60 seconds between one set and another. Additionally, three sets of 8 repetitions (80% 8RM) were performed with an interval between sets of 120 seconds. The execution speed was determined at a moderate level (2s for concentric, 2s for eccentric). It was measured before and during (series 1, series two, and series 3. Named as moments) heart rate exercises using POLAR, model RS800CX Multisport® and blood pressure using OMRON M6 (HEM-7001- E) ®. Then, the double product was calculated using the formula [HR (bpm) X SBP (mmHg)]. Results: In the heart rate analysis, there was an intra-condition difference for moments 1, 2, and 3 compared to rest (p <0.000). In the inter-condition comparison, no differences were observed for rest (p = 0.994) and for moments 1, 2 and 3 (p> 0.999). In systolic blood pressure, intra-conditions, differences were observed for moments 1, 2, and 3 compared to rest (p <0.000). In the inter-condition comparisons, there were no differences between rest (p> 0.999), moment 1 (p = 0.714), 2 (p = 0.999) and 3 (p> 0.999). For diastolic blood pressure, intra conditions, for bench press no significant differences were found for moments 1 (p = 0.331), 2 (p = 0.505) and 3 (p = 0.505) when compared to rest. In the same way it was for the crucifix, wherein the comparison with rest, no difference was observed in moments 1 (p = 0.849), 2 (p = 0.195) and 3 (p = 0.105). In the same sense, no difference was also observed in the comparisons between conditions for rest (p> 0.999), moment 1 (p = 0.999), 2 (p = 0.989) and 3 (p = 0.948). Finally, the double product in intra-condition comparisons found differences between moments 1, 2, and 3 compared to rest (p <0.000). However, in the inter-condition comparisons, no difference was observed at rest (p = 0.999), moment 1 (p = 0.868), 2 and 3 (p> 0.999). Conclusion: It is suggested that resistance training composed of mono and multi-joint exercises offers differences in hemodynamic responses but without differences between the types of mechanics applied by the exercises. Therefore, these results offer a partiality of what can happen with heart rate, blood pressure, and double product.

This study aimed to evaluate and to compare the acute response, due to semi-immersive virtual reality (VR) and conventional therapies (CT), of hemodynamic parameters in hospitalized individuals admitted to an emergency unity for heart failure (HF). This is a viability study with 11 individuals subjected to sessions with and without VR. At CT, stretching, active or active-assisted exercises, and fractional inspiration were performed. In VR therapy (VRT), VR box glasses were used to promote VR relaxation associated with CT. The hemodynamic parameters evaluated were heart rate, systolic and diastolic blood pressure, oxygen saturation, and double product. To analyze them, Student’s t- and Mann Whitney tests were used (p<0.05). Comparing baseline and final evaluations showed no significant differences in the hemodynamic parameters of both groups (p>0.05). Comparing absolute variations between CT and VRT also produced no significant differences between hemodynamic responses (p>0.05). Results showed that administering VRT and CT promoted physiological changes in the responses of hemodynamic parameters in individuals with HF hospitalized in an emergency unit without significant differences between the two interventions. This study suggests that VRT is a hemodynamically safe method for treating patients in emergency units.
