To counteract insulin resistance, it is necessary to increase the utilization rate of fatty acids in blood and adipose tissue. The aim of the present study was to determine the relation between metabolic responses and exercise duration from changes in the respiratory exchange ratio (RER). The mean RER during 30 minutes of moderate exercise (mean pulse 115 beats/min) was 0.89 +/- 0.02, indicatin...

a r t i c l e i n f o Real exchange rates exhibit important low-frequency fluctuations. This makes the analysis of real exchange rates at all frequencies a more sound exercise than the typical business cycle one, which compares actual and simulated data after the Hodrick-Prescott filter is applied to both. A simple two-country, two-good, international real business cycle model can explain the v...

A single bout of exercise can alter subsequent resting metabolism for many hours and into the next day. However, differences between men and women, effects of nutritional state, and relative effects of resting metabolic rate (RMR) and respiratory exchange ratio (RER) in controlling the increase in lipid oxidation (Lox) after exercise are not yet clear. Effects of aerobic capacity (Vo2 peak) and...

In this paper, the link between capital inflows and real exchange rate movements in LDCs is revisited theoretically and empirically. On the theoretical side we present a simple model to show that the real exchange rate depends mainly on “real fundamentals” such as terms of trade or productivity differentials. Empirically, we take into account the heterogeneity of the sample, the dynamics of the...

The real exchange rate (RER) misalignment is a key variable in academic and policy circles. Among policy circles, sustained RER overvaluations are observed by authorities for future exchange rate adjustments. Some countries, on the other hand, have pursued very active exchange rate policies in order to undervalue their currencies to foster growth through export promotion (e.g. China). Our goal ...

Air consumption, oxygen uptake (VO(2)), carbon dioxide output (VCO(2)) and respiratory exchange ratio (RER=VCO(2)/VO(2)) were measured directly from the self-contained breathing apparatus (SCBA) as 36 professional firefighters (three women) completed scenarios of high-rise stair climbing and fifth floor search and rescue. During stair climbing VO(2) was 75+/-8% VO(2max) (mean+/-SD), RER=1.10+/-...

The leptin receptor-deficient db/db mouse is a rodent model of type 2 diabetes and obesity. Diabetes in db/db mice shows an age-dependent progression, with early insulin resistance followed by an insulin secretory defect resulting in profound hyperglycemia. However, there is insufficient data on agedependent changes of energy metabolism in db/db mice. We demonstrated an age-dependent decrease i...
