Very Intense Exercise – training is extremely potent and time efficient: a reminder Edward F. Coyle of the University of Texas at Austin  wrote for the Journal of Applied Physiology           June 2005 vol. 98 no 6

The study by Burgomaster et al. illustrates the importance of very short intense sprint training that can greatly increase aerobic endurance.  The findings also indicate that short duration intense sprint training causes adaptations in skeletal muscle and increases mitochondrial enzyme citrate synthase activity.

“The findings of Burgomaster et al. challenge the concept that aerobic endurance performance is only enhanced by aerobic endurance training”.  Edward F. Coyle

Exercise Develops Children’s Bone Health

A research study published November 2007 in the Canadian Institutes of Health Research states exercise is an important factor in bone development. “The message we hope to convey is that small amount of exercise goes a long way to improving bone health in children” Heather McKay Director Centre for Hip Health and Musculoskeletal Research Vancouver Coastal Health Research Institute

Do You need a training reference to help you find the right exercise for a particular muscle group.  The Exercise and Muscle Directory is one of the best resources on the Web. This link is valuable as a training aid and as a Kinesiological resource.
