Abstract. We analyze a proof of Bruck to obtain an explicit rate of asymptotic regularity for Cesàro means in uniformly convex Banach spaces. Our rate only depends on a norm bound and a modulus of uniform convexity. One ingredient for the proof by Bruck is a result of Pisier, which demonstrates that every uniformly convex (in fact, every uniformly nonsquare) Banach space has some Rademacher type with a suitable constant . We explicitly determine and , which only depend on the single value of our modulus. Beyond these specific results, we summarize how work of Bruck has inspired developments in the proof mining program, which applies tools from logic to obtain results in various areas of mathematics.
