2. Fig. 1
Forearm blood flow during intrabrachial infusions of sodium nitroprusside (SNP, 3 μg/min 12–18 min, 10 μg/min, 18–24 min), acetylcholine (ACh, 7.5 μg/min 42–48 min, 15 μg/min 48–54 min) and LNMMA in the experimental arm (solid line) before (○) and after (•) a 3 month training period. The hatched line denotes blood flow in the contralateral control arm. *P<0.05 for ACh effect before vs. after training by analysis of variance. The insert shows the % decrease in basal blood flow before (B) and after (A) training, *P<0.05 before vs. after.
