While attending the EGL Regionals, I noticed that most of the athletes obviously held their breath before going into a jump. Isn't this counter-productive? Even in simple exercises, we are instructed when to exhale and inhale. I know I watch my piano students carefully for this habit, because the temptation to not breathe is strong. When is this habit corrected, if a coach wished to correct it? I noticed this in gymnasts, also, while watching the broadcast of the world gymnastics championships today.
