Abstract
Landing is a common movement that occurs in many sports. Barefoot research has gained popularity in examining how shoes can alter natural movements. However, it is unknown how a single leg landing under barefoot conditions, as well as landing height, will affect ground reaction forces (GRF). PURPOSE: The purpose of this research was to examine the differences in ground reaction forces during a single leg landing under barefoot and shod conditions from various heights. METHODS: Sixteen female Division II collegiate athletes, 8 basketball (age: 19.88 ± 0.64 yrs; height: 1.77 ± 0.09 m; mass: 75.76 ± 12.97 kg) and 8 volleyball (age: 20.00 ± 1.07 yrs; height: 1.74 ± 0.08 m; mass: 72.41 ± 5.41 kg), performed single leg landings from 12 inches, 18 inches, 24 inches, and 30 inches barefoot and shod. An AMTI AccuGait force plate was used to record GRF. A 2 (condition) x 4 (box height) x 2 (sport) repeated measures ANOVA was performed to determine any GRF differences. RESULTS: There were no significant three way or two-way interactions for GRF (p > 0.05). There was also no main effect for sport (p > 0.05). There were main effects for footwear and box height (p = 0.000) where shod (2295.121 ± 66.025 N) had greater impact than barefoot (2090.233 ± 62.684 N). CONCLUSIONS: Single leg shod landing produced greater vertical ground reaction forces (vGRF) than during a barefoot landing. Current research continues to be contradictory on whether or not barefoot activities lower GRF; therefore, it is important to continue research in this area.
