1. The aim of this study was to provide direct evidence that sympathetic outflow to the skin in humans is governed by central neural mechanisms. 2. Microneurographic measurements of skin sympathetic nerve activity (SNA) from the personal nerve was performed in nine subjects during: (1) static hand grip at 10, 20 and 30% maximal voluntary contraction (MVC);(More)
The present work provides insight into the relative contribution of different mechanisms in regulating sympathetic discharge to skin and skeletal muscle in humans. Activation of sympathetic nerve activity during common behaviours such as orthostasis and exercise was shown to be highly selective, depending on the specific sympathetic outflow under study.(More)
To determine whether oral branched-chain amino acids (BCAAs) improve exercise capacity, six fasting patients with McArdle's disease were given a solution of BCAA (77 mg/kg) or a control noncaloric beverage 30 minutes before exercise. The BCAA meal tripled plasma BCAA levels, increased BCAA catabolism as indicated by greater exercise increases in plasma(More)
