Correlation between Plantar Pressure and Striking Speed in Karate-do

The present paper focuses on a topic that represents a permanent concern for the authors. The correlation between plantar pressure and execution speed in Karate-do is a major issue for achieving competition objectives. A correlation was established between maximal pressure values (on the left and right feet - the correct stance) and execution speed while performing the strikes specific to Karate-do. We found that the correlation coefficients achieved high to very high values, which proves that the striking speed is strongly influenced by maximal pressure (the correct stance) on each foot. At the same time, we noticed that all the correlation coefficients had positive values, which means that any of the couples of variables we have considered acts in the same direction. Therefore, if one of the variables is on a descending trend, the other will also be on a descending trend, while if a variable is on an ascending trend, the other will also be on an ascending trend.
