This study examined patterns of responses for physiological and perceptual variables during cycle ergometry at a constant rate of perceived exertion (RPE) within the moderate and heavy exercise intensity domains. Nineteen (mean age 21.3 ± 0.5 years; 43.4 ± 2.0 mL·kg−1·min−1 O ) moderately trained cyclists performed an incremental test to exhaustion and two 60 min constant RPE rides at the RPE c...

OBJECTIVES The purpose of this analysis was to evaluate the prognostic characteristics of peak oxygen consumption (Vo2) and the minute ventilation/carbon dioxide (VE/Vco2) slope of different peak respiratory exchange ratios (RERs) obtained from cardiopulmonary exercise testing in patients with heart failure (HF). BACKGROUND For patients with HF, peak Vo2 and the VE/Vco2 slope are used for ass...

OBJECTIVE To determine whether walking with a rollator by persons 75 years of age or older is of sufficient intensity to improve aerobic fitness. DESIGN A cross-sectional cohort study. SETTING University movement laboratory. PARTICIPANTS Fifteen subjects 75 years of age or older (mean age, 83.7 y) who could only walk by using a rollator. INTERVENTIONS Not applicable. MAIN OUTCOME MEAS...

This study investigated the physiological difference in recreational runners between a noncontinuous and a continuous endurance training protocol. It also aimed to determine physiological surrogate that could monitor metabolic demand of prolonged running in real-time. For data collection, a total of 18 active male recreational runners were recruited. Physiological (HR, RR, RER, ṼO2, BLa), and o...

This paper investigates the determinants of the real exchange rate (RER) in Ethiopia. In particular, it assesses whether large capital inflows (e.g. foreign aid and remittances) have an impact on the RER. This empirical exercise tries to improve the current literature in a number of ways: (i) the use of quarterly data provides a larger sample size and enables the modelling of important intra-ye...

The purpose of this investigation was to examine the effect of interval (INT) and continuous (CON) cycle exercise on excess post-exercise oxygen consumption (EPOC). Twelve males first completed a graded exercise test for VO2max and then the two exercise challenges in random order on separate days approximately 1 wk apart. The INT challenge consisted of seven 2 min work intervals at 90% VO2max, ...

Abstract Introduction Cardiopulmonary exercise testing (CPEX) provides valuable diagnostic and prognostic cardiopulmonary function data. However, in clinical setting a maximal test is not always achievable. The Oxygen Efficiency Uptake Slope (OUES) has been proposed as possible submaximal measure of it remains relatively stable during the final quartile test. This study explored validity OUES s...

Background and Study Aim. The respiratory exchange ratio (RER) is the of amount carbon dioxide produced (VCO2) to oxygen uptake (VO2) important. It indirectly informs about predominant metabolic pathway provide energy needed during exercise. relationship maximal RER with aerobic anaerobic capacity in athletes remains unclear. purpose this study was investigate between power (VO2max) trained ath...

A cytomorphometric study was performed in lumbar spinal ganglia neurons of Gallus domesticus on the 10th and 18th incubation days and 8th, 35th, 61st, and 120th post-hatching days. The absolute volume of nucleus and relative volume of cytoplasm were respectively estimated by the Bach caryometric method and by point-counting volumetry, carried out in 0.5 micrometer thick araldite sections. The r...
