“The Role of Methylphenidate on Performance in the Cold”
The purpose is to study the effects of dopamine activity, using methylphenidate ingestion, on exercise and cognitive function over the course of a progressive cooling protocol. The investigators hypothesize that methylphenidate will minimize the previously reported impairment in exercise performance and cognitive function with mild hypothermia and cold stress (air temperature: 0EsC) compared to placebo, suggesting that dopamine activity preserves exercise and cognitive capacity with mild hypothermia.
