Shape and scale parameters of the gamma distributions for tennis serve

The shape and scale parameters of the gamma distributions are shown here for the physical dynamics of the tennis serve (red line), the physical dynamics of the martial arts group (blue line), and the decision dynamics of the movement decision time (black line). When plotted on a log/log scale, these parameters align according to a power law.
