Mitochondrial DNA & Maximum Oxygen Consumption

Mitochondrial DNA and Maximum Oxygen Consumption Matthew B Brearley, Shi Zhou School of Exercise Science and Sport Management, Southern Cross University, Lismore, NSW 2480, Australia. Sportscience 5(2), Mitochondrial DNA contains genes for 13 mitochondrial proteins involved in oxygen consumption. Variation in the DNA sequence of these genes could therefore contribute to the differences in endurance performance between individuals. Recent studies have provided conflicting data on the relationship between mitochondrial DNA and an important factor influencing endurance performance, maximum oxygen consumption. The conflict may arise from poorly controlled maternal ethnicity or population differences between studies. Disclaimer: The above is  not linked to CFS, but an interesting read!
