Within-condition clear differences at time point (post-TT1, post-recovery, post-TT2), compared to baseline, and for changes (Δ: TT2 compared to TT1) are denoted as small (0.20-0.49, *), moderate (0.50-0.79, **), or large (≥0.80, ***). Between-condition clear differences at time point, compared to baseline, and between changes are denoted for IPC vs. NMES († ) or IPC vs. AR (‡). For small, moderate or large effects, symbols are presented in italics, bold, or underlined, respectively. Abbreviations: AR, active recovery; Be(b), Be(ecf), base excess of blood and extracellular fluid; BS, baseline; Ca2+, ionized calcium; HCO3-, bicarbonate; cHgb, haemoglobin; Cl-, chloride; cSO2, arterial blood O2 saturation; cTCO2, total CO2; %D, percentage difference; glc, glucose; Hct, hematocrit; IPC, ischemic preconditioning; K+, potassium; lact, lactate; NMES, neuromuscular electrical stimulation; PCO2 and PO2, CO2 and O2 partial pressure.
