A paper from one of our PhD students has just been accepted for publication in the Journal of Sports Science demonstrating that running after cycling does not elicit greater inter-limb asymmetry than prior observations in the literature. This finding is important because triathletes are more susceptible to running related injuries, particularly Achilles Tendinopathy. It has been speculated that the substantial number of injuries triathletes could be associated with large inter-limb differences in movement patterns, external forces and muscle activations. The only difference that we observed during the 5-km time trial was a decrease in activation of the Soleus at the end of the trial for the preferred leg during the pushing phase of stance. More investigation on whether fatigue could anticipate increased loading of the non-preferred limb is required to understand better Achilles Tendon injury mechanism in triathletes.
