Figure 3. Effects of alkalosis on plasma [H⁺] at rest, during finger flexion exercise at 75% WR_peak continued to fatigue, and recovery.

Arterial (A), venous (B) and calculated arterio-venous differences (C) in plasma [H⁺], under Con (•) and Alk (▿) conditions. *Different from rest (P < 0.01, time main effect). †Con > Alk (P < 0.05, treatment main effect). Data expressed as mean ± s.e.m., n = 8. The fatigue point during exercise has been replotted as time zero in recovery. Dashed line represents zero arterio-venous difference.
