Increasing evidences suggest that certain variations in the control region of mitochondrial DNA (mtDNA) are associated with physical performance levels of individuals. The aim of the present study was to assess whether mitochondrial haplogroups are associated with elite athlete status in Iranian population. The mtDNA haplogroups of 100 Iranian athletes and 100 healthy, non-athletic individuals were...
Skeletal muscle is a highly elastic tissue which can respond to various functional demands by altering fiber-type composition. Exercise affects muscle fiber phenotype. One of the transcription factors that induce fiber-type transition is forkhead box O1 (FOXO1). Since eccentric contraction considered an essential part of exercise, so we are interested to see the effects of eccentric exercise (acute/chronic)...
The minimal running velocity at which maximal oxygen uptake (VO2max) is elicited during an incremental test to exhaustion has been used to prescribe training for competitive middle- and long-distance runners. The purpose of this study was to determine the relationship between velocity at lactate turnpoint (vLTP) and vVO2max in long-distance runners. For this purpose 11 highly trained endurance runners...
