Background. The pur­pose of ­this ­study was to deter­mine the var­i­ance ­explained by somat­o­type, select­ed anthro­po­met­ric var­i­ables, and mus­cle ­cross-sec­tion­al ­area (CSA) on 10 km run ­time.
Methods. Subjects ­were 19 ­female and 34 ­male mod­er­ate­ly ­trained dis­tance run­ners who com­pet­ed in a ­local 10 km ­road ­race. Mean ­ages ­were 39.7± 9.2 for ­females and 42.7±10.3 yr for ­males.
Results. Endomorphy ­explained 41.0% (R=0.64, SEE=6.5 min) of the var­i­ance in ­females' 10 km ­time, where­as ­body ­mass ­index ­explained 28.0% (R=0.53, SEE=7.8 min) ­with mes­o­mor­phy add­ing 10.4% (R=0.62, SEE=7.3 min) ­more ­explained var­i­ance in ­males' run­ning ­times. With ­data com­bined for men and wom­en, endo­mor­phy ­explained 22.1% (R=0.47, SEE=7.9 min) of the var­i­ance.
Conclusions. It was con­clud­ed ­that somat­o­type and ­body ­mass ­index ­explain a mod­er­ate por­tion of the var­i­ance in 10 km run per­for­mance in run­ners het­er­o­ge­ne­ous in abil­ity. Muscle and mus­cle ­plus ­bone ­cross-sec­tion­al ­area of relat­ed run­ning mus­cles ­does not con­trib­ute to the ­explained var­i­ance in men. Research seek­ing to ­explain sourc­es of vari­a­tion in run­ning per­for­mance ­should con­sid­er includ­ing somat­o­type as an inde­pen­dent var­i­able.
