The purpose of this study is to assess the effects of different strategies of health on the levels of physical activity (PA), physical fitness (PF), cardiovascular disease (CVD) risk factors and quality of life (QoL) of the institutionalized elderly. Concurrently studies were made of the effect of detraining on these same variables. In this investigation we carried out a prospective longitudina...

Thirteen standardbred horses were trained as follows: phase 1 (endurance training, 7 wk), phase 2 (high-intensity training, 9 wk), phase 3 (overload training, 18 wk), and phase 4 (detraining, 12 wk). In phase 3, the horses were divided into two groups: overload training (OLT) and control (C). The OLT group exercised at greater intensities, frequencies, and durations than group C. Overtraining o...

To the Editor: Pellicchia et al1 should be congratulated for their unique database and their recent paper on ventricular remodeling after cessation of competitive sports in elite athletes. Their conclusion that ventricular cavity size and wall thickness decreased in all athletes after detraining is consistent with reports in previous longitudinal studies.2,3 However, their observation that vent...

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 mechanisms underlying the loss of resting bradycardia with detraining were studied in rats. The relative contribution of autonomic and non-autonomic mechanisms was studied in 26 male Wistar rats (180-220 g) randomly assigned to four groups: sedentary (S, N = 6), trained (T, N = 8), detrained for 1 week (D1, N = 6), and detrained for 2 weeks (D2, N = 6). T, D1 and D2 were treadmill trained 5...

The aim of the present study was to investigate the effects of a 12 week detraining after a 16 week multicomponent training program including strength, anaerobic and aerobic exercises on the main determinants of Asymmetric Dimethylarginine (ADMA), homocysteine (Hcy) and some physiological markers. For this purpose, twenty-three well-trained young wrestlers (14.9±1.1 yr, 46.6 ± 9.949.4 ± 9.6kg, ...

this study aimed to assess the effects of four weeks of detraining after eight weeks of intense sprint training on risk factors of atherogenic inflammatory damages. for this purpose, 42 male rats were divided randomly into two groups: sprint training group (experimental) (n=24 and weight 210±7) and control group (n=18 and weight 211±3). the training program was performed for 12 weeks, three ses...

The purpose of this study was to compare the effects of combined strength and plyometric training with or without superimposed electromyostimulation (EMS) on muscle strength and anaerobic power. Twenty-nine subjects were randomly assigned to weight+plyometrics+EMS (EP), weight+plyometrics (VP), and control group (CG). Weight+plyometrics+EMS and VP performed 2 plyometric sessions and 2 weight tr...

The purpose of this study was to compare the effects of nonlinear resistance training (NRT) and aerobic interval training (AIT), and detraining on selected inflammatory markers in men who are middle aged and obese. Subjects first were matched by aerobic capacity, age, and percentage body fat and then randomly assigned to NRT (n = 12), AIT (n = 10) and, control (CON, n = 11) groups. The experime...

Studies using animal models have been unable to determine the mechanical stimuli that most influence muscle architectural adaptation. We examined the influence of contraction mode on muscle architectural change in humans, while also describing the time course of its adaptation through training and detraining. Twenty-one men and women performed slow-speed (30 degrees /s) concentric-only (Con) or...
