Data are from the vastus lateralis muscle of 8 males (n = 7 for 15 h post, because of technical issues) and are expressed as means ± SE. M′/M₀, ratio of P_i magnetization with and without selective saturation of γ-ATP; T₁′, apparent longitudinal relaxation time of P_i with saturation of γ-ATP; k′, P_i→ATP exchange pseudo first-order rate constant; V_rest, resting P_i→ATP flux. P values are for main effect from repeated measures ANOVAs; post hoc statistical differences (P < 0.05) between 1 and 2 (

^*), and 1 and 3 (

^†) are indicated.
