Heat and exercise alone may not determine how much we sweat
... elicited 65 percent of the individual's predicted maximal
heart rate at a pedaling cadence of 60 rpm. After the exercise bout, the subject either stopped all leg movement or, on a separate day, the subject's legs were passively moved (at 60 rpm) via a second person cycling the tandem ergometer. The order of...
Gene alteration points to longevity, thinness

lifespan of about four weeks. Dr. Fei cloned all three of the acid transporters in the C. elegans, knocked down the activity of each and found that the newest transporter Indy increased the lifespan of the worm and decreased body size and fat conten...
Deciphering the limits to human maximal exercise performance
... during centuries what is the main factor limiting maximal
exercise capacity in humans. During the past century evidence has accumulated suggesting that maximal
exercise capacity in humans is limited by the maximal

Ambient light influences the evolution of colour signals

conspicuousness is achieved for signals which are rich in the colours of ambient light but poorly reflected by background, different signals will be cryptic or conspicuous at different heights in tropical rainforest. In the forthcoming issue of Ecol...

Can the mode of training affect the hormone response to different modes of exercise?

force generation during potassium-depolarization. Cumulative dose response curves for the -adrenergic agonist phenylephrine, (PE) 0.1-10 mM and ET-1 (0.01-10 mM) were preformed. Cumulative dose-response protocols were completed either in the absence ...
New study shows why hypertension affects black males disproportionately

Small subset of cells has big role in controlling immunity, study finds
...that IDO has to be present for the reagent to have maximal
