Why does reverse swing occur?

Why does reverse swing occur?

Reverse swing is a high leveled skill used by seam bowlers in cricket. Reverse swing differs from conventional swing as it swings towards the shined side rather than towards the rough side. This occurs due to he rough side of the ball experiencing more turbulence and the shiny side having less air turbulence when moving through the air. Due to this side having less air turbulence the ball moves towards this side; ultimately creating reverse swing.  

Deterministic Model for 100m Sprinting

A Deterministic Model for 100m Sprinter

The first performance criterion of the deterministic model is race time due to this being the main focus of a 100m sprint. A sprinter will aim to reduce their race time in order to improve their performance. This first principle can then be split into phases as shown. The race time can be split into start time, stride rate and dip speed. Stride rate can then be split into two principles; stride length and average stride time.
