the purpose of this study was to determine the effect of interval sprint exercise and a detraining period on lipid peroxidation (mda) and the response of antioxidant system (frap, uric acid, bilirubin and total protein). for this purpose, 35 male rats were divided randomly into two groups: sprint group (experimental) (n=20) and control group (n=15, without any training). experimental group trai...

Complete energy balance measurements were made in exercise-trained (treadmill running) rats subjected to 27 d of exercise detraining. The 20% difference in body-weight that existed at the end of the training period between sedentary and trained rats was negated by detraining. Detrained rats had twice the body-weight gain of their untrained controls. An elevation (12%) in metabolizable energy (M...

The response of human muscles triceps brachii and vastus lateralis to training, consisting of 18.5 miles a day of skiing with a backpack, 6 days a week for 8 weeks, has been investigated by means of histochemical fiber typing (myofibrillar ATPase) as well as immunohistochemical discrimination of slow and fast myosin (n = 6). A detraining period of 33 weeks was also studied. The percentage of ty...

Hypertrophic cardiomyopathy is one of the main causes sudden cardiac death in young athletes. Differentiating between this pathological condition and ‘athlete's heart’ can be quite challenging, warranting a thorough clinical imaging assessment. Clinicians often rely on detraining-induced attenuation electrocardiographic echocardiographic findings as means distinguishing physiological remodeling...

the aim of this study was to determine the effect of two kinds of resistance training and one period of detraining on serum levels of myostatin, cortisol, testosterone and muscle strength of non-athlete men. for this purpose, 34 non-athlete men (age 33.35+2.8 yr) were divided into three groups: experimental a (4 sessions of training per week), experimental b (3 sessions of training per week) an...

PURPOSE The purpose of this study was to evaluate the pressure-flow specificity of adaptations to inspiratory muscle training (IMT), in addition to the temporal effects of detraining and reduced frequency of training upon these adaptations. METHODS Twenty-four healthy subjects were assigned randomly to one of four groups (A: low-flow-high-pressure IMT; B: high-flow-low-pressure IMT; C: interm...

Nelson, Amanda J., and Gary A. Iwamoto. Reversibility of exercise-induced dendritic attenuation in brain cardiorespiratory and locomotor areas following exercise detraining. J Appl Physiol 101: 1243–1251, 2006. First published June 22, 2006; doi:10.1152/japplphysiol.00483.2006.—It has been shown previously that dendritic branching in cardiorespiratory and locomotor brain areas can be attenuated...

PURPOSE The training response of an intensified period of high-intensity exercise is not clear. Therefore, we compared the cardiovascular adaptations of completing 24 high-intensity aerobic interval training sessions carried out for either three or eight weeks, respectively. METHODS Twenty-one healthy subjects (23.0±2.1 years, 10 females) completed 24 high-intensity training sessions througho...

Modulators of loading-induced in vivo adaptations in muscle-tendon complex (MTC) mechanical properties remain unclear. Similarly contentious, is whether changes in MTC characteristics are associated with growth factor levels. Four groups were subjected to varying magnitudes of stress/strain: Group 1 trained with the MTC at a shortened position (MTCS; n = 10); Group 2 at a lengthened position (M...
