Running has a high incidence of Achilles tendon (AT) injuries that may be due to high forces and repetitive loading. Running cadence may influence AT loading. To promote a 10% cadence increase, auditory, visual, and tactile cues were used. Thirty-four male and female runners ran on an instrumented treadmill at 7.5 mph where kinetic and kinematic data were obtained. AT cross-sectional area was measured with ultrasound imaging. Inverse dynamics then static optimization were used to calculate muscle forces and AT loading. All cued conditions increased cadence from the baseline run condition. Auditory and visual cues yielded a cadence increase closest to 10%. There was no difference between auditory and visual cues to increase cadence (p<0.05). AT-related loading variables such as peaks in ground reaction force, AT force, and soleus muscle force were lower when cadence increased to near 10%. Visual and auditory cues reduced AT loading most compared to the run (baseline) condition. Understanding the relationship between the use of cues and increasing cadence may aid in the treatment and prevention of AT injuries.
