Notes for this study:
In this randomized, double-blind, placebo-controlled crossover trial, 7 male endurance-trained athletes took 150 mg/kg of tyrosine or an isocaloric amount of whey protein prior to exercise testing in high heat (30 degrees C) conditions.

There wasn't a difference between groups in time to completion or power output during the cycling test. There was also no effect on heart rate, temperature, urine osmolality or body mass losses. There wasn't a statistically
