Exercise and recovery metabolism in the pacific spiny dogfish (Squalus acanthias)

We examined the effects of exhaustive exercise and post-exercise recovery on white muscle substrate depletion and metabolite distribution between white muscle and blood plasma in the Pacific spiny dogfish, both in vivo and in an electrically stimulated perfused tail-trunk preparation. Measurements of arterial-venous lactate, total ammonia, β-hydroxybutyrate, glucose, and l-alanine concentrations in the perfused tail-trunk assessed white muscle …
