When you are finishing up a hockey workout or intense practice, it’s important to engage in some form of cool down activity. The cool down is primarily in place to act as a bridge between your active self and your non-active self, both mentally and physiologically. This bridge between intense exercise and rest is important for hockey players to build as an immediate halt in intense activity to doing absolutely nothing can potentially lead to blood pooling, dizziness, fainting, and continued elevation of stress hormones that you no longer need.
You have to understand that our bodies undergo a wide series of internal changes in order to support the demands of a hockey game, practice, or workout.
