Objective. To exam­ine the rela­tion­ship ­between the ­peak pow­er out­put (Wmax), ­peak oxy­gen ­uptake (V.O2­peak), low­er ­limb mus­cu­lar ­strength and ­cycling ­time (CT) dur­ing a ­short ­course tri­ath­lon ­race.
Experimental ­design. The ­study ­involved a ­cross-sec­tion­al anal­y­sis involv­ing ­both phys­io­log­i­cal and bio­me­chan­i­cal var­i­ables. Setting. Testing was per­formed at the exer­cise phys­iol­o­gy and bio­me­chan­ics labor­a­to­ry, School of Exercise Science and Sport Management, Southern Cross University, Lismore, Australia.
Participants. Ten ­male tri­ath­letes who had ­been endu­rance ­cycle train­ing for a min­i­mum of 12 ­months ­prior to the com­mence­ment of the ­study.
Measures. Subjects com­plet­ed a max­i­mal incre­men­tal ­cycle ­test as ­well as a ­series of mus­cu­lar func­tion ­tests includ­ing a 6-s ­cycle ­test, a con­cen­tric iso­iner­tial ­squat ­jump as ­well as an iso­ki­net­ic leg exten­sion ­test per­formed at veloc­ities of 60° (s-1, 120° (s-1 and 180°•s-1. In addi­tion, ­each sub­ject ­also par­tic­i­pat­ed in a tri­ath­lon ­race of dis­tance 1.5 km ­swim, 40 km ­cycle and 10 km run.
Results. A sig­nif­i­cant cor­re­la­tion exist­ed ­between CT and abso­lute V.O2­peak and Wmax. However, no sig­nif­i­cant cor­re­la­tions ­were ­found ­between the ­results of the mus­cu­lar func­tion ­tests and the incre­men­tal ­cycle ­test as ­well, as CT dur­ing the tri­ath­lon ­race.
Conclusions. Wmax and WDmax are use­ful var­i­ables in assess­ing ­cycle per­for­mance in tri­ath­letes. However, the impor­tance of mus­cu­lar ­strength of the low­er ­limbs may be min­i­mal in over­all ­cycle per­for­mance dur­ing a ­short ­course tri­ath­lon ­race.
