Amplitude of the forearm blood flow (FBF; A) and FVC (B) responses during dynamic forearm exercise at 10%, 20%, and 30% MVC in young and older adults under control (saline) and NO synthase (NOS) inhibition (l-NMMA) conditions. Under control conditions the amplitude of the FBF and FVC responses was attenuated in older adults at 30% MVC. NOS inhibition (l-NMMA) also blunted the amplitude of the hyperemic and vasodilator responses at 30% MVC in young adults. *P < 0.05 vs. young, †P < 0.05 vs. control.
