Question

consider this claim: expensive athletic gear does not improve athletic performance. which is the strongest evidence to support the claim? \we found that people feel no more motivated to exercise when they wear expensive athletic gear than when they wear affordable athletic clothes,\ remarked social scientist ethan navarro. some athletes perform without the use of expensive athletic gear. for instance, many long - distance runners from the tarahumara tribe in mexico run practically barefoot, with only strips of old material strapped to the bottom of their feet. while the expensive compression garments worn by athletes are often believed to improve blood flow and thereby enhance performance, a study of male runners indicates otherwise. paul browning, who has played soccer professionally for the past decade, said in a recent interview that he believes expensive athletic clothing makes no difference in an athletes performance.

Explanation:

The first option only addresses motivation, not performance. The second option is an anecdote about some athletes, not a comprehensive study. The fourth option is just one athlete's opinion. The third option is a study on a specific type of expensive gear (compression garments) that directly challenges the supposed performance - enhancing effect, making it the strongest evidence.

Answer:

While the expensive compression garments worn by athletes are often believed to improve blood flow and thereby enhance performance, a study of male runners indicates otherwise.
