| Values | Figure 1. " 15 ± 11% longer in TYR compared to PLA (80.3 ± 19.7 min vs. 69.2 ± 14.0 min; P = 0.006;" |
| Trial Design | Randomized trial |
| Trial Length | 24 hours |
| Number of Subjects | 8 |
| Sex | Male |
In this randomized, double-blind, placebo-controlled crossover trial, 8 healthy male participants took 150 mg/kg of tyrosine or placebo prior to exercise in hot conditions (30 degrees C, 60% relative humidity).
The tyrosine group saw a greater time to exhaustion. There was no statistically significant effect on blood glucose, lactate, or plasma volume, heart rate, temperature, rate of perceived exertion, thermal sensation.
