Abstract
Context: Although previous research has shown that navicular drop increases with fatigue of the foot intrinsics, it is unclear whether or not this occurs in a functional setting.
Objective: To evaluate navicular drop in collegiate distance runners before and after distance runs and track workouts.
Design: Descriptive Laboratory Study
Setting: University outdoor practice facilities
Participants: Fifteen healthy collegiate cross country runners (10 males, 5 females)
Intervention: None
Main Outcome Measures: Navicular drop (cm)
Results: There was a significant interaction between workout and time for WBAH (F1,14=9.333, p=.009, η2=.400). Main effect for time was significant (F1.14=6.512, p=.023, η2=.317). Post hoc tests showed post-workout WBAH (4.95±.62) was lower than pre-workout height (5.12±.56; p=.02). Post hoc results revealed post-workout WBAH (4.82±.16 cm) were significantly lower than pre-workout measurements (5.18±.55 cm, p
Conclusions: We speculate that the greatest change in arch height was seen after an interval workout due to the differences in shoes between the two workout types (spikes during interval as opposed to normal running shoes for distance). Additionally, we believe the change in WBAH after both workout types are likely due to anatomical changes of the foot due to functional fatigue of the intrinsic foot muscles.
