Elena is the head coach of an elite national biathlon squad. Biathlon competition requires athletes to transition rapidly from intense cross-country skiing (requiring high physiological arousal and gross motor power) to precise rifle shooting (requiring low arousal, fine motor control, and extreme cognitive focus).
