Chronic exercise training elicits adaptations in the heart that improve pump function and confer cardioprotection. To identify molecular mechanisms by which exercise training stimulates this favorable phenotype, a proteomic approach was employed to detect rat cardiac proteins that were differentially expressed or modified after exercise training. Exercise-trained rats underwent six weeks of pro...

BACKGROUND Although exercise training has well-known cardiorespiratory and metabolic benefits, low compliance with exercise training programs is a fact, and the harmful effects of physical detraining regarding these adaptations usually go unnoticed. We investigated the effects of exercise detraining on blood pressure, insulin sensitivity, and GLUT4 expression in spontaneously hypertensive rats ...

All of the adaptations acquired through physical training are reversible with inactivity. Although significant reductions in maximal oxygen uptake (Vo2max) can be observed within 2 to 4 wk of detraining, the consequences of detraining on the physiology of adipose tissue are poorly known. Our aim was therefore to investigate the effects of discontinuing training (physical detraining) on the meta...

OBJECTIVES To examine the effects of age on functional fitness after six weeks of detraining. METHODS Elderly subjects, aged 60-86 years, completed a nine week multicomponent exercise training programme. They performed the senior fitness test every two weeks during the six week detraining period, and the responses of 12 young-old subjects (YO, aged 60-73 years) and nine older subjects (O, age...

Objective: The aim of this study was to investigate the effect of 6 weeks of detraining after 12 weeks of high intensity interval training (HIIT) on the expression of AKT1 and mTORc1 genes in the left ventricle of wistar diabetic rats. Materials and Methods: Twenty-eight wistar male rats were selected as the study sample and were divided in four groups of healthy control, diabetic control, dia...

Intensity-controlled (relative to VO2max) treadmill exercise training in adult rats results in the activation and ensuing differentiation of endogenous c-kit(pos) cardiac stem/progenitor cells (eCSCs) into newly formed cardiomyocytes and capillaries. Whether these training-induced adaptations persist following detraining is undetermined. Twelve male Wistar rats (~230 g) were exercised at 80-85%...

The aim of this study was to evaluate the effects of exercise training (ET, 50-70% of VO2 max, 5 days/week) and detraining (DT) on inflammatory and metabolic profile after myocardial infarction (MI) in rats. Male Wistar rats were divided into control (C, n = 8), sedentary infarcted (SI, n = 9), trained infarcted (TI, n = 10; 3 months of ET), and detrained infarcted (DI, n = 11; 2 months of ET +...
