Playing With Statistics [Part 5]By Mladen Jovanovic on 26/03/2012
Playing With Statistics Although at the end of part 4 I mentioned I will talk about analysis of frequent tests like sRPE, HRV and other’s that are used for monitoring, I will not do that in this part. Maybe in part 6 because I am still ‘playing~struggling’with that one. What I want to talk today is data...

After a general rant in part 1 I will now try to be more pragmatic. Please note that with these posts I am not trying to impress lab coats, but rather provide an example for my fellow coaches who deal with testing and assessment. Nothing fancy, just down to earth analysis.

Recently I have seen EXCELLENT presentation from Stuart Cormack regarding monitoring in rugby.

Take a acceleration phase in sprinting for an example. Ground reaction force passes through body’s center of mass (or slightly outside of it causing certain torque around body’s sagital axis) and certain component of it provides the propulsion force. The bigger the propulsion force, the greater the acceleration. The body inclination can affect this, but to get into more incline position...
