Dear Biomch-L subscribers,

Aging leads to a reduction in the economy of whole body movement,
probably due to several factors. Is anyone aware of work that has been
done on whether there are differences in the metabolic cost of force
production (tension cost) or work/power production (thermodynamic
efficiency) between young and elderly skeletal muscle fibres? Any
reference to human or animal studies would be much appreciated as i have
only been able to locate a single rat study using pubmed/medline/sport
discus/web of science searches (De Haan A, de Ruiter CJ, Lind A, and
Sargeant AJ. Age-related changes in force and efficiency in rat skeletal
muscle. Acta Physiologica Scandinavica 147: 347-355, 1993).

A summary of responses will be posted.
