Smith’s veins are more prominent due to a lowering of his subcutaneous fat as well as a protein called vascular endothelial growth factor that triggers new vein growth to accommodate for the increased demand of oxygen by Smith’s larger muscles.

Patricia Obee lets out a yawn as partner Lindsay Jennerich checks the course while leaving the dock prior to the semi-final in the women’s lightweight double sculls at the second world cup of the season in Lucerne, Switzerland on May 27th, 2016.
