However, data supporting this position are not definitive. Research from studies of sport expertise indicates that differences between experts and non-experts in cognitive sports are found only in domain-specific, information-processing abilities that are primarily the result of training. Future research should examine an interactionist perspective to consider the relative contribution of genes and training to performance.o*$http://sportsci.org/jour/0102/jb.htm'~xSchool of Physical and Health Education, Queens University, Kingston, ON K7L 3N6, Canada.

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.,%http://sportsci.org/jour/0102/mbb.htm0'School of Exercise Science and Sport Management, Southern Cross University, Lismore, NSW 2480, Australia.

In the breakdown of a glucose molecule to 2 pyruvate molecules, three reactions release a total of four protons, and one reaction consumes two protons. The conversion of 2 pyruvate to 2 lactate by lactate dehydrogenase (LDH) also consumes two protons. Thus lactate production retards rather than contributes to acidosis. Proton release also occurs during ATP hydrolysis, In the transition to a higher exercise intensity, the rate of ATP hydrolysis is not matched by the transport of protons, inorganic phosphate and ADP into the mitochondria. Consequently, there is an increasing dependence on ATP supplied by glycolysis. Under these conditions, there is a greater rate of cytosolic proton release from glycolysis and ATP hydrolysis, the cell buffering capacity is eventually exceeded, and acidosis develops. Lactate production increases due to the favorable bioenergetics for the LDH reaction. Lactate production is therefore a consequence rather than a cause of cellular conditions that cause acidosis. Researchers, clinicians, and sports coaches need to recognize the true causes of acidosis so that more valid approaches can be developed to diminish the detrimental effects of acidosis on their subject/patient/client populations.,%http://sportsci.org/jour/0102/rar.htm'ngExercise Science Program, University of New Mexico, Albuquerque, NM 87059, USA.
