01 · The sentence it was drawn from

“L-arginine supplementation had no effect from initial VO2max (PL, 58.7 ± 7.1 ml·kg·min; ARG, 63.5 ± 7.3 ml·kg·min) to postsupplement VO2max (PL, 58.9 ± 6.0 ml·kg·min; ARG, 63.2 ± 7.2 ml·kg·min).”
Quoted verbatim from VO2max and ventilatory threshold of trained cyclists are not affected by 28-day L-arginine supplementation.
