Perspiration
I'm wrapping up the spring season, with my athletes competing in various state tournaments and meets. Most of these athletes are also completing final exams. Whether in the arena or in the classroom, the post-season lends itself to focusing on the outcome. Whenever evaluation, expectations, consequences, or time constraints are present, there is an elevated sense of pressure. In an understandable desire to perform well, focus begins to shift away from the present to the future (i.e. the outcome). Consequently, performers attempt to consciously control their performance as opposed to relying on the subconscious mind. Instead of playing loose and free, they become tense and tight as the brain directs action and seeks to avoid mistakes. The prefrontal cortex is great at problem solving, but it's no match for the coordination, speed, and automaticity provided by the basal ganglia and cerebellum.
When you find yourself caught up in the outcome, acknowledge the thought. Then, refocus on the task at hand. Recognize how your body responds to moments of consequence, and reframe it as excitement, rather than nerves. Finally, relying on routines and relaxation techniques can help get you back in the flow.
