We incorporated a swim tunnel exercise regimen during zebrafish caudal fin regeneration to explore exercise loading impacts on a robust model of tissue regeneration. Early exercise loading  initiated before or during blastema formation  resulted in reduced regenerative outcomes. Long term tracking of fluorescently labeled cell lineages showed exercise loading disrupted blastemal mesenchyme formation. Transcriptomic profiling and section staining indicated loading reduced an extracellular matrix ECM gene expression program  including for hyaluronic acid HA synthesis. Like exercise loading  HA synthesis inhibition or blastemal HA depletion disrupted blastema formation. We considered if injury upregulated HA establishes a pro regenerative environment facilitating mechanotransduction.  HA density across the blastema correlated with nuclear localization of the mechanotransducer Yes associated protein Yap. Further  exercise loading or HA depletion decreased nuclear Yap and Proliferative Cell Nuclear Antigen staining. We conclude early loading during fin regeneration disrupts expression of an HA rich ECM supporting blastema expansion. Our study of mechanical loading during fin regeneration reveals a stage dependent response similar to that seen in mammalian skeletal repair  where early exercise\u2014applied during blastema establishment\u2014impairs regeneration  while delayed loading during outgrowth does not  suggesting a conserved sensitivity to the timing and intensity of mechanical stimuli in regenerative processes.
