## 3 Results
### Comparisons between Women and Men  
Tables 4-6 show the results for comparisons between women and men for each foot, biomechanical intraphase, and session for the first, second, and third steps, respectively. During heel strike, mid-stance, and take off of the stance phase, men had significantly larger contact surface areas than women. In Figure 1, samples of each phase of the third step can be seen. \begin{table}
