A meta-analysis of placebo-controlled crossover trials found reduced aerobic time-trial completion times with both low- and moderate-dose oral anhydrous caffeine, but the evidence was mostly derived from male participants, cycling studies, and trials using doses no higher than 6 mg/kg.
A review of 56 qualitative studies found residents' emotional experiences were influenced by interactions among training demands, workplace relationships, and their evolving professional identity.
