Physiological Characteristics of Masters-Level Cyclists
Journal of Strength and Conditioning Research, 2008Although a considerable amount of research is available describing the physiological characteristics of competitive young-adult cyclists, research describing these same characteristics in Masters-level cyclists is rare. Therefore, the purpose of this study was to describe and compare the effect of aging on physiological fitness parameters of Masters ...

Physiological Characteristics of Female Masters Swimmers
The Physician and Sportsmedicine, 1981In brief: Two female masters swimmers, ages 70 and 71, members of the 1980 All-American Masters Swim Team, were compared with sedentary females of the same age and with younger female athletes. They had considerably lower percent body fat than normal sedentary women in their 70s and were well within the range for normal women who are 19 to 25 years old.

Physiological Characteristics of Elite Soccer Players
Sports Medicine, 1993Soccer is one of the most popular sports in the world. There is still much uncertainty and debate surrounding its physiological requirements because emphasis is on skills to the neglect of fitness, conservative training methods and the difficulty of studying the sport scientifically.

Physiological Characteristics of the Eye
1986Much of the equipment and technology used in closed-circuit TV, including video microscopy, is borrowed from broadcast TV. It should be noted that broadcast TV has never sought to produce a perfect optical image from a remote location, but rather to provide an instant facsimile of lifelike scenes economically to an audience scattered over wide ...

Spatiotemporal characteristics of physiological gastroesophageal reflux
American Journal of Physiology-Gastrointestinal and Liver Physiology, 1994Recent technological developments have made it possible to measure intraluminal pH simultaneously at multiple sites using one single small-caliber catheter. The aim of this study was to investigate the dynamics of physiological gastroesophageal reflux in eight ambulatory healthy volunteers (age 21-51 yr). Esophageal pH was recorded for 24 h at 3, 6, 9,

Physiological characteristics of platelet serotonin in rats
Life Sciences, 1989Physiological characteristics of platelet serotonin (5-HT) levels in rats of Wistar origin were investigated by use of a recently developed method. By comparison of populations of male and female rats (N = 281) similar unimodal frequency distributions, with a tendency to higher values in females (1.61 vs. 1.70 micrograms 5HT/mg platelet protein; p less

Histochemical and physiological characteristics of the rat diaphragm
Journal of Applied Physiology, 1985The histochemical and contractile characteristics of the adult rat diaphragm were determined. Based on enzyme histochemistry, the rat diaphragm contained 40% type I, 27% type IIa, and 34% type IIb fibers. There were significantly more type I fibers in the ventral costal (VEN) compared with the crural (CRU) region of the muscle and a slightly higher ...
