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...

The impact of music and its psychological and physiological changes during exercise is issue that has always been focused on sport science experts. The aim of this study was to compare the effects of musical exercise on aerobic capacity and quality of life in elderly men. This study was conducted on 45 elderly men. The participants were randomly allocated into three groups: aerobic musical exer...

During exercise, ventilation for a given work rate is increased in pulmonary hypertension. In the present editorial a new look at the ventilatory behaviour, which may change the common approach to VE/VCO2 relationship analysis, is presented. The behaviour of ventilation (VE) in a ramp protocol exercise test is peculiar, and it implies relevant physiological information. In a healthy individual,...

In Part 11 of the study, the British Olympic track (sprint) squad cyclists demonstrated reductions in body fat index, % body fat and endomorphy (p > .05), increased Hb and PCV % (p > .05), and lowered HR at rest and in warm-up exercise (p > .05), but no change in leg power. Repeated interval sprints of short duration, maximal exercise on an "ergowheel" ergometer, at standardised power output, s...

Pulmonary O2 uptake kinetics during "step" exercise have not been characterized in young, sprint-trained (SPT), athletes. Therefore, the objective of this study was to test the hypotheses that SPT athletes would have (i) slower phase II kinetics and (ii) a greater oxygen uptake "slow component" when compared with endurance-trained (ENT) athletes. Eight sub-elite SPT athletes (mean (+/-SD) age=2...

To determine the importance of different atrioventricular intervals during exercise in patients with dual chamber pacemakers, seven patients with complete heart block and sinus rhythm were exercised in different pacing modes and atrioventricular intervals: (a) ventricular inhibited (VVI) pacing with no synchronous atrial augmentation or rate responsiveness; (b) atrial synchronous ventricular or...

background: herein, we studied the effects of two different exercise protocols on il-17 and crp plasma levels along with the anti-inflammatory effects of fish oil. the purpose of the present study was to investigate the effect of eicosapentaenoic acid (epa) and docosahexaenoic acid (dha) consumption along with two different types of physical activities on il-17 and crp plasma levels in trained ...

The objectives of the pilot study are to (1) confirm the general observation that an immune-supporting supplement, ASEATM, has an effect on athletic performance and (2) determine the specific physiological parameters: Heart Rates (HR), volume of O2 inspired (VO2), volume of CO2 expired (VCO2), volume of expired gas (VE), Respiration Rate (RR), Respiratory Exchange Ratio (RER), Aerobic Threshold...
