Key Findings
Five days of nitrate-rich beetroot juice raised plasma nitrate and nitrite but produced no change in core or skin temperature, sweat rate, or exercise tolerance in 35 degrees C heat.
Conclusions
Dietary nitrate does not improve thermoregulation or heat exercise tolerance in untrained men.
Limitations
Small crossover sample (n=11), inactive males only, single heat protocol.
Outcomes Measured
No thermoregulatory or ergogenic effect of dietary nitrate among physically inactive males, exercising above gas exchange threshold in hot and dry conditions
