OBJECTIVE The purpose of this study was to evaluate the following: 1) the effects of continuous exercise training and interval exercise training on the end-tidal carbon dioxide pressure (PETCO2) response during a graded exercise test in patients with coronary artery disease; and 2) the effects of exercise training modalities on the association between PETCO2 at the ventilatory anaerobic thresho...

BACKGROUND Aerobic interval exercise training has greater benefits on cardiovascular function as compared with aerobic continuous exercise training. OBJECTIVE The present study aimed at analyzing the effects of both exercise modalities on acute and subacute hemodynamic responses of healthy rats. METHODS Thirty male rats were randomly assigned into three groups as follows: continuous exercis...

Introduction: Diabetes mellitus (DM) is now seen as a worldwide epidemic disease with high prevalence. Exercise training (ET) is known to promote beneficial changes in diabetic patients. The aim of this study was to compare the impact of continuous and intermittent aerobic training on glucose-4 transporter protein (GLUT-4) levels and insulin sensitivity in diabetic rats. Materials and meth...

KEY POINTS Continuous high-intensity constant-power exercise is unsustainable, with maximal oxygen uptake (V̇O2 max ) and the limit of tolerance attained after only a few minutes. Performing the same power intermittently reduces the O2 cost of exercise and increases tolerance. The extent to which this dissociation is reflected in the intramuscular bioenergetics is unknown. We used pulmonary gas ...

objective(s): the goal of this study was assessing the prophylactic effect of exercise and its role as an adjuvant therapy on level of cytokines involved in angiogenesis in estrogen-dependent breast cancer. materials and methods: forty female balb/c mice were randomly assigned to exercise-tumor-exercise (ete), exercise-tumor-rest (etr), rest-tumor-exercise (rte) and rest-tumor-rest (rtr) groups...
