Figure 3. The impact of cycling performed before endurance training in the moderate (Δ_MI) versus heavy (Δ_HI) intensity domain on the plasma branched-chain amino acids (A) and plasma lactate concentration (B).

Asterisk (*) represents significant difference from Δ_MI (p < 0.05, repeated measures 2-way ANOVA). Data are shown as mean ±  S.E.M. Abbreviations: [Leu]_pl, plasma leucine concentration; [Ile]_pl, plasma isoleucine concentration; [Val]_pl, plasma valine concentration; [∑ BCAA]_pl, the sum of plasma BCAA concentration, [La⁻]_pl, plasma lactate concentration; Δ_MI, the difference between value measured at ∼50% of VO_2max and value measured at rest; Δ_HI, the difference between value measured at 100% of VO_2max (PO_max) and value measured at ∼70% of VO_2max.
