Background: Neuromuscular responses and adaptations associated with loading schemes to the knee joint have been a topic of interest in the realm of biomechanics and researchers have looked at this via drop landings from various box sizes and drop landings after lower extremity fatigue.
Hypothesis/Purpose: The purpose of the study was to assess neuromuscular activity of the muscles surrounding the knee joint before and after static loading to the knee joint capsule during drop landings. It was hypothesized that the knee joint capsule stretch would provide a significant neuromuscular modification during single leg drop landing.
Methods: 20 male and female participants ages 19-26 from SIU participated in 5 successful drop landing task before and after a 10 minute static knee stretch.
Results: There were numerous significant findings with muscle ratio, muscles, and time series with all pre and post drop landings. There were no differences in the gender.
Discussion: Our findings suggest that the muscles of the knee joint during drop landings post static loading that were significant with certain muscle ratios (as described in table 4) and the pre/post condition. Our hypothesis showed that the neuromuscular modification were observed. When looking at the data there was no difference when looking at pre and post conditions, but there was a trend showing that it could become significant. There were differences with muscle ratios pre and post drop landing.
