A high intensity short duration exercise training programme was undertaken by nine subjects on three occasions each week for nine weeks. Muscle samples from the latissimus dorsi were taken by needle biopsy, at rest, before and after training. The results revealed that there was no change in either Type I or Type II muscle fibre distribution following training. Type I fibre area did not alter si...

Background: Despite the growing popularity of bouldering, little is known about degree and variabilityof muscle activation that occurs while solving bouldering problems. The purpose this study was to explorethe electromyography eight upper extremity trunk muscles during a session indoor whilecompleting four different problems.Methods: Eleven climbers with self-reported ability climb V-scale V4 ...

Phenotypical differences between muscle fibers are associated with a source of cellular energy. Coenzyme Q 10 (CoQ 10 ) is a major component of the mitochondrial oxidative phosphorylation process, and it significantly contributes to the production of cellular energy in the form of ATP. The objective of this study was to determine the relationship between whole-tissue CoQ 10 content, mitochondri...
