UNLABELLED Resistance training (RT) is a proven sarcopenia countermeasure with a high degree of potency. However, sustainability remains a major issue that could limit the appeal of RT as a therapeutic approach without well-defined dosing requirements to maintain gains. PURPOSE To test the efficacy of two maintenance prescriptions on muscle mass, myofiber size and type distribution, and stren...

the purpose of the present study was to determine the effect of four weeks of detraining after 12 weeks of continuous and intermittent aerobic training on high sensitive c-reactive protein (hs-crp) in rats (325.6±4.93 grams and 21 months old and their fertility period expired 3 months ago). for this purpose, 80 female wistar rats with strain 14848 were prepared and divided into three groups: co...

the present study attempted to compare the structural and functional changes of left heart ventricle in female basketball players of khuzestan superior league (aged between 18 and 29) during regular training and long-term detraining. out of 30 female players, 15 subjects were assigned randomly to regular training group and 15 subjects to long-term detraining group. the structural and functional...

RESULTS: After 16 weeks of this open-trial intervention, significant increases in maximum inspiratory pressure and maximum expiratory pressure (27.6% and 20.54%, respectively) were demonstrated. Considerable improvement in quality of life was also observed. The clinical evaluations and daily recorded-symptoms diary also indicated significant improvements and fewer respiratory symptoms. A month ...

introduction: during ramadan, type and amount of energy intake dramatically change in muslims and fasting individuals often reduce the duration and intensity of physical activities or avoid exercise during this month. however, one of the major issues of trainers and athletes is lack of training, which could have adverse effects on some cardiovascular parameters. methods: this research was condu...

INTRODUCTION Sarcopenia is currently best described as an age-related decline in skeletal muscle mass and function. However, no consensus exists as to how to best quantify muscle function in older adults. The muscle quality index (MQI) was recently recommended as an ideal evidence-based assessment of functional status in older adults. Nevertheless, the usefulness of MQI to assess physical funct...

BACKGROUND Although resistance exercise interventions have been shown to be beneficial in prefrail or frail older adults it remains unclear whether there are residual effects when the training is followed by a period of detraining. The aim of this study was to establish the sustainability of a muscle power or muscle strength training effect in prefrail older adults following training and detrai...

PURPOSE There is an inverse relationship between insulin sensitivity and percentage of myosin heavy chain IIx (MyHC IIx) isoform in sedentary, obese, and type 2 diabetic humans. How different exercise conditions may reduce the proportion of MyHC IIx and in parallel elevate glucose transporter 4 (GLUT4) content is interesting in a therapeutic setting. This study investigates the nature of exerci...

BACKGROUND In coronary artery disease, exercise training (ET) is associated with an improvement in endothelial function, but little is known about the relative effect of different types of training. The purpose of this study was to prospectively evaluate the effect of different types of ET on endothelial function in 209 patients after a first recent acute myocardial infarction. METHODS AND RE...

BACKGROUND Exercise has been found to either reduce or increase arterial stiffness. Land-based exercise modalities have been documented as effective physical therapies to decrease arterial stiffness. However, these land-based exercise modalities may not be suitable for overweight individuals, in terms of risks of joint injury. The purpose of this study was to determine the effects of 8-week swi...
