What is the catastrophe theory in sports?
The catastrophe theory in sport suggests that an athletes arousal level needs to lower significantly if they want to improve their performance. Only then will an athletes performance gradually increase back up to the optimum point if arousal increases. Somatic and cognitive arousal is needed to achieve optimum point.
What is a 250 year return period?
The loss amount that has a 1 percent probability of being equaled or exceeded in any given year. The loss amount that has a 0.4 percent probability of being equaled or exceeded in any given year. The industry also calls this the 250-year return period loss or 250-year probable maximum loss (PML).
