Despite the rapid development of new or novel molecular techniques and their application to diagnosis, quality assurance and quality control have not necessarily kept-up with the developments. [...]the authors highlight the increasing complexity for quality assurance and the necessity for harmonization and standardization of quality measures. From the muscle biopsies the limitation of intensive exercise was correlated with a partial shutdown of mitochondrial respiratory function and hydrogen peroxide production. The authors strongly recommended that those undertaking strenuous exercise should carefully monitor their body responses to reduce the negative effects of exercise, which could be undertaken by monitoring glucose homeostasis.
