The ACE gene and muscle performance
Article Abstract:
The presence of the longer ACE allele, which has an insertion of 287 base pairs, gives an improved mechanical efficiency in trained muscle, according to research into training-related changes in the mechanical efficiency of human skeletal muscle. The effect of the II genotype in improving the mechanical efficiency of trained muscle may be linked to a rise in slow-twitch rather than fast-twitch muscle fibres, which are more efficient in slow contraction. These findings have implications in other areas, including congestive heart failure.

Human gene for physical performance
Article Abstract:
New research shows that human physical performance is enhanced by a polymorphism in the gene that encodes angiotensin-converting enzyme. The research finds that the I (insertion) allele of the gene is linked with improved endurance among high-altitude mountaineers. It is suggested that the improved performance may result from variable increases in substrate delivery because of increased muscle capillary density and higher cardiac output.

Exercise and reduced muscle mass in starlings
Article Abstract:
Issues are presented concerning the control of muscle development in starlings so as to maintain a balance between the energy cost of flying and a good standard of flight performance.
