background: the purpose of the present study was to investigate the effect of endurance training on amount of nicotinic acetylcholine receptors (nachr) in fast and slow twitch muscles of male wistar rats. methods: a number of 15 male wistar rats randomly divided into two groups of control (n=7) and endurance training (n=8). the endurance training treadmill running (for 12 consecutive week, 5 da...
Objective: The 3000-meter run is one of the most popular and enduring materials among endurance and semi-endurance races and because of the special conditions of this field, which can use aerobic and anaerobic energy production systems at the same time. We evaluated the effect of eight weeks resistance and endurance training on physiological, functional factors and elite runner's record. Metho...
Impaired respiratory muscle endurance (RME) could reduce exercise tolerance and contribute to ventilatory failure. The aim of the present study was to develop a clinically-feasible method to measure RME using negative-pressure inspiratory-threshold loading. It was hypothesized that endurance time (tlim) could be predicted by normalizing oesophageal pressure-time product (PTP) per total breath c...
Objective: The purpose of this study was to investigate the effect of eight-weeks of general preparation exercise on some selected biomechanical, anthropometrical and physiological parameters of the Iranian women’s national Taekwondo team. Methods: Nine elite members of Iranian women’s national Taekwondo team (age 23/22±1/98 years old, and weight 61/88±8/44 kg) partic...
Evaluation of seismic behavior of offshore platforms is one of the important design steps in seismic regions. Nevertheless, because of complication and time cost of these methods, engineers usually do not study them deeply. Endurance Time (ET) method is a good solution for this problem. In this method, with acceptance of a reasonable region of errors, the time of analysis can be reduced conside...
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...
Objective: Few studies have been conducted on variations of the central nervous system of diabetic patients and much fewer investigations done on the cerebellum of diabetes patients. The current research aims to investigate the effect of endurance training on neurotrophic factors affecting the cerebellum in the diabetic rat. Materials and Methods: This study is experimental.Twenty Wistar rat w...
OBJECTIVES To evaluate the utility of our newly devised method (incremental stand-up exercise-load) to determine features of general endurance in hemiplegic patients. SUBJECTS/PATIENTS Participants were 15 healthy adults and 15 hemiplegics, with 13 men and 2 women in each group. METHODS To evaluate endurance, the subjects were required to assume a sitting position on a bed for 3 minutes and...
Study objective: The aims of this work were to determine (1) whether patients with COPD have impaired skeletal muscle performance (ie, maximal strength and endurance) compared with healthy subjects, and (2) whether the level of physical activity, body composition, and lung function are related to skeletal muscle performance in COPD patients. Methods: Seventeen COPD patients and eight healthy ag...
