Figure 3. Total work performed (A), Plasma [K⁺] (B), and the rise in plasma [K⁺] relative to work performed (ΔK⁺].work⁻¹ ratio) (C) during 10 sets of 30 maximal eccentric knee extensor contractions.

Values are means ± SD; n = 6. # P<0.05– significantly different from Set 1. *P<0.05– significantly different from Rest. • P<0.05– significantly different from Set 2.
