Northstar Performance Index

Northstar Performance Index (NPI): The NPI is conducted by Ron Greenfield, a prominent strength and conditioning professional who has trained many successful collegiate athletes, and in particular, women’s lacrosse players. The NPI is designed to test the following: speed, agility, endurance, and general athletic capacity. 

The NPI consists of many of the same Testing Mechanisms used by the majority of collegiate programs, and was created to provide relevant and quantitative metrics to evaluate athletes’ speed and agility, change of direction, body control, level of endurance, and mental focus. The NPI is also designed to expose Northstar athletes to the Sports Performance requirements and metrics they will see at the next level.
