[Purpose] This study was conducted to determine the influence of Taekwondo as security martial arts training on anaerobic threshold, cardiorespiratory fitness, and blood lactate recovery. [Subjects and Methods] Fourteen healthy university students were recruited and divided into an exercise group and a control group (n = 7 in each group). The subjects who participated in the experiment were sub...

The effects of chronic dynamic exercise on myocardial /3-adrenergic and muscarinlc cholinergic receptors and chronotropic sensitivity to isoproterenol were studied in 5 Yucatan miniswine. Right atrial and left ventricular biopsies, heart rate responses to isoproterenol, and maximal exercise treadmill testing were obtained before and after 10-19 weeks of treadmill running. Radioligand studies us...

The effects of chronic dynamic exercise on myocardial beta-adrenergic and muscarinic cholinergic receptors and chronotropic sensitivity to isoproterenol were studied in 5 Yucatan miniswine. Right atrial and left ventricular biopsies, heart rate responses to isoproterenol, and maximal exercise treadmill testing were obtained before and after 10-19 weeks of treadmill running.

BACKGROUND Maximum aerobic capacity (VO2max) is associated with lower cardiovascular and total mortality. Step tests can be used to provide an estimate of (VO2max) in epidemiological or home-based studies. We compared different methods of estimation of VO2max and heart rate recovery and evaluated the relationship of these estimates with cardiovascular risk factors. METHODS Data were analysed ...

Introduction: Metabolic syndrome is defined as a cluster of metabolic disorders, which may lead to type II diabetes and cardiovascular diseases. Promotion of healthy lifestyle and use of herbal supplements with anthocyanin and phenols are recommended for the treatment of metabolic syndrome. The present study aimed to investigate the effects of eight weeks of combined aerobic an...
