This study, which involves 10 male swimmers, is to examine the effects of endurance training on the anaerobic threshold (AT), maximal oxygen uptake (VO_2 max) and cardiac output (Q), and to find out therelationship between the changes in cardiac function and anaerobic threshold during training.
In order to make an accurate prediction about athletes' maximal oxygen intake, the present study has used a computer to process such physiological data of female Wushu masters and gymnasts as heart rate, oxygen pulse, ventilatory volume and so forth at the quantitative work, then chosen some more significant factors among them to form three best stepwise regression equations It has been shown, after test and verification, that the results predicted with the above equations can precisely represent the work capacity of athletes.
by method of gradual load-increasing test on Ergometer Bicycle, 24 female college students were tested for heart and lung function in exercising, the results showed that: Maximal oxygen intake capacity and the relative value of it, maximal ventilation capacity, heart rate, pulse frequency, percents of oxygen intake capacity at the lacticthreshold were higher significantly in students of tested group than those in students of contrasted group.
Introduced the combined technology of TG-DTA-FTIR to measure the following parameters at different phases: the moisture content of coal, the initial temperature, the quantity of absorbed oxygen, the quantity of released heat, the initial temperature and component of released gas and ignition point and so on. Advanced that it is irrational to show the susceptibility of spontaneous combustion of coal with the quantity of absorbed oxygen at some temperature or the total absorbed oxygen at some oxidation phase.
TA2000/MDSC2901 differential scanning apparatus was used to study the effect of contained moisture content of coal to the absorbed oxygen and released heat. Through study, it was found that contained moisture content has complex relation with the total absorbed oxygen and released heat. And it was also found that there are the maximum values of the total absorbed oxygen and released heat at the low contained moisture and a little high contained moisture content respectively.
Oxygen uptake rate (OUR) of the activated sludge (AS) was determined to indicate the changes of AS activity stimulated by ultrasound at 35 kHz for 0-40 min with ultrasonic intensities of 0-1.2 W/cm2.
The mean particle diameter and specific oxygen uptake rate of Bioferric-SMBR were 3.10 and 1.23 times the common SMBR, respectively.
Oxygen uptake by photobacteria was shown to be insensitive to chlorophenols, at least within the concentration range that was effective in bioluminescence inhibition.
Cloning and Expression of the Vitreoscilla Hemoglobin Gene in Enterobacter Aerogenes: Effect on Cell Growth and Oxygen Uptake
There are well-documented studies showing that bacteria expressing Vitreoscilla hemoglobin (VHb), the first prokaryotic hemoglobin characterized, have better growth and oxygen uptake rates than their VHb counterparts.
The rates of heart beat and oxygen intake showed that P.
Noradrenaline is 27% (0.10>amp;lt;p>amp;lt;0.05) higher, pulse rate is 6% (p>amp;lt;0.05) lower, oxygen intake 4% (>amp;gt;0.05) lower, and the glycerine level 25% (0.10>amp;lt;p>amp;lt;0.05) lower during maximal BE exercise.
The heart rate and the oxygen intake don't show any position dependent differences at rest and at the same submaximum levels.
During maximum ergometric exercise they are 15% (heart rate) and about 30% (oxygen intake) higher than in supine position, corresponding to a higher exercise level.
This paper is the result of an investigation into the regulation of oxygen intake in silver eels, Anguilla vulgaris L.
By measuring the amount of absorbed oxygen and analyzing the solution by means of photocolorimetry, the effect the cathodic hydrogenation exerts on iron corrosion in an aerated solution of 0.05 N H2SO4 + 1 N Na2SO4 at 20°C is studied.
A formerly developed electrochemical cell able to continuously measure the oxygen corrosion rate of a metal through the absorbed oxygen quantity is described.
In the presence of antifoam agents the three-stage column has a higher cell productivity, OTR, kL a and a lower specific energy requirement with regard to the absorbed oxygen and/or produced cell mass than the single stage column.
The contained cercariae, however, remain healthy and appear to consume most of the absorbed oxygen.
The free radical concentration in lipid-protein mixtures with a low moisture content was monitored both during and after the time that the lipid actively absorbed oxygen.
