Abstract summarizedQuality not appraised
What was studied
A crossover trial tested whether beetroot juice increased repetitions to failure.
Who / model studied
Sixteen resistance-trained women.
Studied dose & schedule
Juice with 12.8 mmol nitrate, placebo with 0.92 mmol, or no drink, 2.5 hours before bench and leg press at 60% of maximum.
What the study found
Bench repetitions were 56.0 with nitrate versus 58.9 with placebo; leg-press repetitions were 79.3 versus 80.4. Differences were not significant. Exertion, heart rate, blood pressure and lactate also did not improve.
Limitations & context
Small acute study with substantial variability; does not rule out other nitrate regimens or exercise contexts. Abstract assessment; adverse-event counts unavailable.
