Muscles were prelabeled with [³H]arachidonate, subjected to 15–90 min of mechanical stretch or control conditions, and measurements were made of PLD activity (A) or the concentration of ³H-labeled PA ([³H-PA]) (B) at the indicated time points. Graphs represent the mean values ± SEM for each group expressed as a percentage of the time-matched control (n = 3–4 per group). ∗, significantly different from time-matched control, (P ≤ 0.05).
