What the rows share
From the rowsThe best-graded row, grade C, is a crossover trial of 22 people (2017) and found an improvement.
The rows run from 13 to 28 people, published from 2016 to 2025: 4 single studies.

10-km time trial was faster (49.5 vs 50.8 min, p = 0.03) at similar heart rate and effort. The 5-km run 24 hours later was faster (23.2 vs 23.9 min, p = 0.003), and creatine kinase and fatigue rose less.

- DGrade D30-minute cycling time-trial power · Improved
Crossover RCT · n 28 · 2018 · Trained male cyclists
100 mg/day · 7 days per condition
Average absolute power was higher (231.6 vs 225.3 W, p = 0.050, d = 0.02); relative power, distance, lactate, nitric-oxide and inflammatory markers did not differ. Exercise efficiency in the last 5 minutes improved (p = 0.029).

Crossover RCT · n 13 · 2016 · Competitive male runners (mean age 25)
100 mg/day for 6 days, then 50 mg before testing · 7 days per condition
5-km time (23.0 vs 23.6 min) was faster in 10 of 13 runners. During steady running, heart rate was 3% lower, perceived exertion 15% lower and blood lactate 14% lower (p = 0.05).

- DGrade DRunning economy, VO2max and recovery muscle oxygenation · Mixed
Crossover RCT · n 17 · 2025 · Male recreational runners (mean age 19)
Single 100 mg dose · Single session
Running economy and VO2max did not improve. Heart rate at 80% VO2max and maximum heart rate were lower, perceived exertion at 60% was lower, and post-exercise muscle oxygenation was higher; lactate clearance did not change.
