Hypothesis and results

Factor	Hypothesis	Study results
LDHA	Short distance AA > AB > BB	Overall no differences; trend AB > BB in longer races
DRD4	Longer distance CTCT > CTCC or CCCT > CCCC, CCTT, TTCC, TTTT	Overall CCCT > CCCC or CCTT, largest effect in shorter races
F-KER	Overall and in longer races TT > TG, or GG	Overall GG shows best result; in longer races TT > GG
MSTN	Longer races TT > CT > CC	Sample size too small to draw conclusions
mtDNA Queen L	Presence > absence in longer races	No difference in longer races; shorter races: absence > presence
Gender	Male = female	Male = female
Color	Checker = blue	Checker > blue
