although sport-physiologists have repeatedly analyzed respiratory gases through exercise, it is relatively new in the cardiovascular field and is obviously more acceptable than standard exercise test, which gives only information about the existence or absence of cardiovascular diseases (cvds). through the new method of exercise test, parameters including aerobic and anaerobic are checked and m...

We have recently demonstrated that changes in the work of breathing during maximal exercise affect leg blood flow and leg vascular conductance (C. A. Harms, M. A. Babcock, S. R. McClaran, D. F. Pegelow, G. A. Nickele, W. B. Nelson, and J. A. Dempsey. J. Appl. Physiol. 82: 1573-1583, 1997). Our present study examined the effects of changes in the work of breathing on cardiac output (CO) during m...

BACKGROUND AND OBJECTIVE Peak aerobic capacity (VO2 peak) is an important outcome measure in cystic fibrosis (CF), but measurement is not widely available and can be influenced by patient motivation, pain and fatigue. Alternative markers of disease severity would be helpful. Neural respiratory drive, measured using parasternal intercostal muscle electromyography (EMGpara), reflects the load to ...

BACKGROUND Cardiopulmonary exercise test (CPET) is the most complete tool available to assess functional aerobic capacity (FAC). Maximum oxygen consumption (VO2 max), an important biomarker, reflects the real FAC. OBJECTIVE To develop a cardiorespiratory fitness (CRF) classification based on VO2 max in a Brazilian sample of healthy and physically active individuals of both sexes. METHODS We...

OBJECTIVE This study sought to correlate the anthropometric and functional variables, and exercise habits in a group of elderly adults who regularly attend exercise programs. METHOD Participation of 217 subjects between 60 and 85 years of age, from 13 regions of Colombia. Anthropometric and functional assessment was conducted as a questionnaire on exercise habits. RESULTS Negative correlati...

The aim of this study was to find out the relationship between selected anthropometric and physiological variables of college level female long jumpers and sprinters. Fifteen female sprinters and fifteen female long jumpers of Post Graduate Government college sector-11 Chandigarh were tested. The range of age for all female sportspersons lies from 20 to 25 years. The selected anthropometric mea...

Maximal oxygen uptake (VO2 max) belongs to most important functional parameters of physical fitness testing and consideration of endurance capabilities. The value of VO2 max depends on age, gender, genetic disposition, body dimensions and physical fitness. Spiroergometric examination was done on cycle ergometer (ramp 25-35 W per minute) at vita maxima. One hundred and seventy children (129 boys...
