We compared two hypothesized energetic costs for swinging the human leg quickly. The first cost is to perform mechanical work on the leg, and the second is to produce muscle force cyclically at high frequencies. Substantial metabolic energy is expended to perform isolated leg swinging, especially at rates greater than the leg's natural pendular frequency. To determine whether the production of ...
Alpine skiing, both recreational and competitive, is associated with high rates of injury. Numerous studies have shown that occupational exposure to whole-body vibrations is strongly related to lower back pain and some suggest that, in particular, vibrations of lower frequencies could lead to overuse injuries of the back in connection with alpine ski racing. However, it is not yet known which f...
Introduction Covalently attached prosthetic groups serve as swinging arms in several different and wellcharacterized multifunctional enzymes. Notable among these are the lipoyl-lysine residues in 2-0x0 acid dehydrogenase multienzyme complexes [l-31 and the glycine cleavage system [4-61, the biotinyl-lysine residues in various ATP-dependent carboxylases [7,8] and the phosphopantetheinyl-serine r...
Swinging arms are a key functional component of multistep catalytic transformations in many naturally occurring multi-enzyme complexes. This arm is typically a prosthetic chemical group that is covalently attached to the enzyme complex via a flexible linker, allowing the direct transfer of substrate molecules between multiple active sites within the complex. Mimicking this method of substrate c...
