We determined the independent and interactive influences of aging and habitual endurance exercise on calf venous compliance in humans. We tested the hypotheses that calf venous compliance is 1) reduced with age in sedentary and endurance-trained men, and 2) elevated in young and older endurance-trained compared with age-matched sedentary men. We studied 8 young (28 +/- 1 yr) and 8 older (65 +/-...
PURPOSE Fatigue of trunk muscle contributes to spinal instability over strenuous and prolonged physical tasks and therefore may lead to injury, however from a performance perspective, relation between endurance efficient core muscles and optimal balance control has not been well-known. The purpose of this study was to examine the relationship of trunk muscle endurance and static balance. METH...
There are strong genetic components to cardiorespiratory fitness and its response to exercise training. It would be useful to understand the differences in the genomic profile of highly trained endurance athletes of world class caliber and sedentary controls. An international consortium (GAMES) was established in order to compare elite endurance athletes and ethnicity-matched controls in a case...
The purpose of this study was to find out the effect of concurrent strength and endurance training on selected endurance parameters namely Cardio-respiratory endurance and Resting pulse rate. To achieve this purpose, thirty students from the Department of Physical Education and Sports Sciences, Annamalai University, Annamalai Nagar, TamilNadu and India were selected as subjects at random. Their...
A variety of anthropometric and training characteristics have been identified as predictor variables for race performance in endurance and ultra-endurance athletes. Anthropometric characteristics such as skin-fold thicknesses, body fat, circumferences and length of limbs, body mass, body height, and body mass index were bi-variately related to race performance in endurance athletes such as swim...
Background and Objective: Alzheimer is a neurodegenerative disease in which a reduced memory capacity and numerous changes occur in the patient’s brain. This study was embarked to shed light on the effects of eight weeks of endurance training and lithium chloride administration on brain-derived neurotrophic factor serum levels in female rats with Alzheimer's disease. Materials and Methods: 7...
We present a generalised phase field formulation for predicting high-cycle fatigue in metals. Different degradation functions are presented, together with new damage accumulation strategies, to account (i) typical S-N curve slope, (ii) the endurance limit, and (iii) mean stress effect. The numerical implementation exploits an efficient quasi-Newton monolithic solution strategy Virtual curves co...
introduction: cardiac remodeling after myocardial infarction, is associated with progressive ventricular dysfunction and cardiovascular death. the purpose of this study was to examine the effect of endurance exercise training on morphological changes in rat heart tissue following experimental myocardial infarction. materials and methods: rats used in this experiment (8-10 weeks old, 235 ± 5 g b...
