### Pressure Load on Parts of the Feet (F/H)  
For further investigation of the load preference of a certain part of the foot, we tested the front part-rebound part (toes and metatarsals) and the back part-instep part-heel and tarsal part. We verified how the front part of the left foot is loaded depending on the sport., i.e., we were looking for an answer to whether this forefoot of the left foot is loaded equally regardless of the sport. We verified the same with the load on the back of the left foot depending on the sport. Normality tests performed using the Shapiro-Wilk test confirmed the normal distribution of the data. By comparing the loading of parts of the left feet with a t-test, we found a significant dependence (\(p\) = 0.008) of overloading of the rear part of the foot depending on the type of sport performed (\(t\)-value: 2.804 \(>\) critical \(t\)-value: 2.024). When testing the load on the right foot, we noticed overloading of the front part of the \begin{table}
