The effect of eccentric strength training on heart rate and on its variability during isometric exercise in healthy older men
(2009-01-01)
The purpose of this study was to investigate if chronic eccentric strength training (ST) affects heart rate (HR) and heart rate variability (HRV) during sub-maximal isometric voluntary contractions (SIVC). The training ...

Efeito do envelhecimento sobre o comportamento mecânico dos músculos papilares de ratos Wistar.
(1993-04-01)
PURPOSE--To evaluate the effects of age on mechanical performance of rat myocardium. METHODS--Left ventricular papillary muscles were isolated from male Wistar rats at 1, 3, 6 and 12 months of age. Muscles were studied ...

Influência da pós-carga sobre a taxa de variação da tensão desenvolvida (dT/dt). Estudo em músculo cardíaco isolado.
(1995-11-01)
PURPOSE: To evaluate the effects of afterload on peak rate of tension rise (dT/dt) in the isolated muscle. METHODS: Left ventricular papillary muscles from Wistar rats were studied in isometric and isotonic afterloaded ...

Etude electromyographique des muscles trapezius (partie moyenne) et rhomboideus major sousmis a tension isometrique
(1981-01-01)
The participation of the trapezius (middle portion) and rhomboideus major muscles submitted to an isometric tension (holding downward dumbells of 11, 15 and 19 kg) was analysed in 40 young adult male vounteers. A 2 channel ...
