Figure 2. A–C: Protocol 2 – Impact of Occluding Skeletal Muscle Blood Flow during Exercise on Venous Plasma ATP.

Figure 2

Moderate intensity forearm handgrip exercise evoked significant elevations in venous plasma ATP during both steady state (SS; 4 minutes) and at end exercise (6 minutes) time points (A). When skeletal muscle perfusion ceased via complete blood flow occlusion (Occl), plasma ATP was significantly reduced from SS exercise and was no longer greater than rest (B). Application of a cuff to completely occlude forearm blood flow prior to exercise abolished any significant increase in plasma ATP resultant from exercise (C). * P <0.05 vs rest; † P <0.05 vs SS Ex.
