Post-concurrent exercise hemodynamics and cardiac autonomic modulation

Abstract: Concurrent training is recommended for health improvement, but its acute effects on cardiovascular function are not well established. This study analyzed hemodynamics and autonomic modulation after a single session of aerobic (A), resistance (R), and concurrent (A + R) exercises. Twenty healthy subjects randomly underwent four sessions: control (C:30 min of rest), aerobic (A:30 min, cycle ergometer, 75% of VO2 peak), resistance (R:6 exercises, 3 sets, 20 repetitions, 50% of 1 RM), and concurrent (AR: A + R). Before and after the interventions, blood pressure (BP), heart rate (HR), cardiac output (CO), and HR variability were measured. Systolic BP decreased after all the exercises, and the greatest decreases were observed after the A and AR sessions (−13 ± 1 and −11 ± 1 mmHg, respectively, P < 0.05). Diastolic BP decreased similarly after all the exercises, and this decrease lasted longer after the A session. CO also decreased similarly after the exercises, while systemic vascular resistance increased after the R and AR sessions in the recovery period (+4.0 ± 1.7 and +6.3 ± 1.9 U, respectively, P < 0.05). Stroke volume decreased, while HR increased after the exercises, and the greatest responses were observed after the AR session (SV, A = −14.6 ± 3.6, R = −22.4 ± 3.5 and AR = −23.4 ± 2.4 ml; HR, A =+13 ± 2, R =+15 ± 2 vs. AR =+20 ± 2 bpm, P < 0.05). Cardiac sympathovagal balance increased after the exercises, and the greatest increase was observed after the AR session (A = +0.7 ± 0.8, R = +1.0 ± 0.8 vs. AR = +1.2 ± 0.8, P < 0.05). In conclusion, the association of aerobic and resistance exercises in the same training session did not potentiate post-exercise hypotension, and increased cardiac sympathetic activation during the recovery period.

Economic Impact of Dengue: Multicenter Study across Four Brazilian Regions

Abstract: Dengue is an increasing public health concern in Brazil. There is a need for an updated evaluation of the economic impact of dengue within the country. We undertook this multicenter study to evaluate the economic burden of dengue in Brazil.

Aptidão física relacionada à saúde de idosos: influência da hidroginástica

Abstract: RESUMENAptitud fisica relacionada con la salud de los anosos: in-fluencia de la hidrogimnasiaFundamentos y objetivos: La practica del ejercicio fisi-co, ademas de combatir el sedentarismo, contribuye demanera significativa para el mantenimiento de la aptitudfisica. El objetivo de este estudio fue el verificar el efectode la practica de la hidrogimnasia sobre la aptitud fisicadel anoso asociada a la salud. Metodologia: Fue realiza-do un ensayo controlado en 74 mujeres anosas, sin activi-dad fisica regular. Un grupo de 37 mujeres recibio dos cla-ses semanales de hidrogimnasia durante 3 meses y otras37 mujeres sirvieron como control. La aptitud fisica eva-luada a traves de la bateria de tests de Rikli & Jones (1999),con evaluaciones de fuerza y resistencia de miembros infe-riores (levantar y sentar la cadera), fuerza y resistencia demiembros superiores (flexion del antebrazo), flexion demiembros inferiores (sentado, alcanzar los miembros infe-riores con las manos), mobilidad fisica – velocidad, agili-dad y equilibrio (levanta, camina 2,44 m y vuelta a sentar-se), flexibilidad de los miembros superiores (alcanzar atrasde las costas con las manos) e resistencia aerobica (cami-nar 6 minutos). La bateria de tests fue aplicada antes delinicio de las clases y al final del programa despues de los3 meses. Los grupos fueron semejantes en relacion a edad,
