objective: recent studies have shown that the use of prolonged and intermittent normobaric hyperoxia (95%) decrease the infarct volume of stroke. the aim of current study was to study the effect of an oxygen radicals-scavenger applied during intermittent normobaric hyperoxia on infarct volume in the rat brain and neurologic deficit. materials and methods: male wistar rats (250-350 g) were divi...

Background. Because VO2max doesn’t provide any detailed information about aerobic examinations Oxygen Kinetic is used for more accuracy. Long intensive and repetitive exercises with sufficient time lead to increase in aerobic parameters like kinetic absorption of oxygen. Objectives. The purpose of this study was to determine time dependent effects of short-time high intensity interval...

the aim of this study was to determine time dependent effects of high intensity interval training (hiit) on oxygen kinetics in young males. 40 active students were randomly assigned to four groups: one session of hiit, two sessions of hiit, four sessions of hiit and control. both hiit and control groups performed the incremental test on an ergometer bicycle. two days after the pretest, training...

Measurements of oxygen deficit during submaximal exercise were correlated with the anaerobic threshold (as measured by gas exchange analysis), peak work rate on a ramp protocol, and the ability to perform constant work rate exercise in 10 male patients with New York Heart Association class 2 congestive heart failure and 12 age- and gender-matched normal controls. All subjects performed a maxima...

CROWELL,JACK W., AND ELVIN E. SMITH. Oxygen de&it and irreversible hemorrhagic shock. Am. J. Physiol. 206 (2) : 3 I 3-3 I 6. rg64.A device was constructed to record continually the oxygen conSumption of a dog and to summate as the oxygen deficit the difference between normal oxygen use and oxygen use during hypotension. Dogs were subjected to hypotension of 30 mm Hg and various oxygen deficits ...

The main purpose of this study was to investigate the effects of an 8-wk severe interval training program on the parameters of oxygen uptake kinetics, such as the oxygen deficit and the slow component, and their potential consequences on the time until exhaustion in a severe run performed at the same absolute velocity before and after training. Six endurance-trained runners performed, on a 400-...
