Abstract

The overall purpose of this study was to better understand impact characteristics during barefoot running. Subjects (n=10; 22.5+/-3.1 yrs; 170.3+/-6.8cm; 66.7+/-10.5kg; 5 male; 5 female) completed ten trials (3.8 m/s) in each of three conditions: (1) Shod, (2) barefoot (BF) running without instruction given on footstrike pattern and (3) barefoot with instruction to run heel-toe (BFHT). Ground contact index (GCI), stride length, impact peak (F1), loading rate, and peak leg acceleration (PkLeg) were analyzed. Repeated measures ANOVAs were used to compare each dependent variable across conditions. Neither stride length nor F1 were different across conditions (p>0.05). Loading rate was greater during BF compared to shod (p<0.001) and BFHT compared to BF (p<0.05). PkLeg was greater during BF vs. shod (p<0.05) as well as BFHT vs. shod (p<0.05). GCI was less during BF vs. shod (p<0.0002) and BFHT vs. BF (p<0.05). There appear to be differences in impact characteristics between shod and barefoot running but these differences appear to be functionally significant.
