1 A technique has been developed for studying over periods of 10 min or longer the effects of drugs on both the force of electrically-induced contractions and the oxygen consumption of an isolated, curarized, mammalian, skeletal muscle preparation.2 The resting oxygen consumption of the muscle was increased substantially by 2,4-dinitrophenol in concentrations (0.02 mM and higher) that eventuall...

Numerous recent studies convincingly correlate the upper thermal tolerance limit of aquatic ectothermic animals to reduced aerobic scope, and ascribe the decline in aerobic scope to failure of the cardiovascular system at high temperatures. In the present study we investigate whether this 'aerobic scope model' applies to an air-breathing and semi-terrestrial vertebrate Rhinella marina (formerly...

The physical and physiological behavior of sickle cell trait carriers (AS) is somewhat equivocal under strenuous conditions, although this genetic abnormality is generally considered to be a benign disorder. The occurrence of incidents and severe injuries in AS during exercise might be explained, in part, by the lactic acidosis due to a greater lactate influx into AS red blood cells (RBCs). In ...

The aim of the study was to compare physiological responses between runners adapted and not adapted to deep water running at maximal intensity and the intensity equivalent to the ventilatory threshold. Seventeen runners, either adapted (n = 10) or not adapted (n = 7) to deep water running, participated in the study. Participants in both groups undertook a maximal treadmill running and deep wate...

We investigated the usefulness of the oxygen intake efficiency slope (OIES) as a submaximal measure of cardiorespiratory functional reserve. OIES was derived from the relationship between oxygen consumption (VO2; ml/min) and minute ventilation (VE; l/min) during incremental exercise, which was determined by the following equation: VO2 = a logVE + b, where "a" represents OIES, which shows the ef...

The purpose of this study was to compare the aerobic fitness of two groups of male college students: 32 Anglo-Saxon males (age range 16-18 years) with 27 Indian males, born in England, (age range 16-23 years), none of whom was highly active in any particular sport. Maximal oxygen uptake was estimated by submaximal test on a cycle ergometer and percent body fat was assessed by skinfold calipers....

[Purpose] The aim of this study was to compare the body composition, heart rate variability, and aerobic and anaerobic performance between competitive cyclists and triathletes. [Subjects] Six cyclists and eight triathletes with experience in competitions voluntarily participated in this study. [Methods] The subjects' body composition was measured with an anthropometric tape and skinfold caliper...

RESULTS Baseline symptom status, left ventricular outflow tract gradients, exercise times and maximal oxygen consumption peak were similar between the two groups. Left ventricular outflow gradient was reduced from 76 6 57 to 9 6 17 mm Hg (p 5 0.0001) after myectomy, and from 77 6 61 to 55 6 39 mm Hg (p 5 0.07) after pacing (p 5 0.02 for comparison with myectomy). Ninety percent of myectomy pati...

The purpose of this study was to determine physical fitness level of lignite miners in the Czech Republic. The authors have examined a representative group of 152 active lignite miners by bicycle spiroergometry. The duration of employment in coal mines ranged between 5 and 32 years. The average age was 43.1 •} 4.7 years. The miners had an average peak oxygen consumption 2.9 •} 0.5 1.min-1, corr...

background maximal oxygen consumption (vo2max) forced vital capacity(fvc), forced expiratory volume(fev1) and maximum voluntary ventilation(mvv) are important indicators of pulmonary functions that show physical health and physical activity of individuals. the aim of the present study was to examine the effects of yoga and aerobic trainings on pulmonary functions parameters in untrained women. ...
