You have probably heard about the importance of building an “aerobic base.” Maybe you think that means just doing long, slow distance (LSD) training.
If you’re looking to get fit in a hurry, you should hit high intensities often. But understand that you are getting fit by only attacking one side of the equation, and there’s a limit to how fit you can ultimately get this way (not to mention a greater risk of injury and overtraining). Complete aerobic fitness happens when you put in the work at low intensities over time and develop the “low end” aerobic adaptations to support the higher intensity work.
Jason Dierking, assistant director for sports performance at the University of Louisville, explains how training load numbers help strength coaches and sport coaches keep student-athletes fit throughout the long season without overtraining them.
By utilizing the Polar Team 2 system over the past seven years, the University of Louisville has brought strength coaches and sport coaches closer together based on a foundation of data.
By looking closely as several key metrics, Louisville’s Jason Dierking uses the Polar Team 2 system to drive decision-making for 11 different sports.
