Question

Officials working for the National Biking Association have made different claims about how Jordan Jones won the American Cycling Classic this year. Right now, which claim do you think is the strongest?
Claim 1: Jordan Jones increased his cellular respiration and improved his performance by blood doping.
Claim 2: Jordan Jones increased his cellular respiration and improved his performance by changing his pre-race meal.

Claim 3: Jordan Jones increased his cellular respiration and improved his performance by training at a higher altitude.
Why do you think that claim is the strongest?

Answer 1

Answer:

Claim 3 is the strongest

Explanation:

Claim 3 is the strongest because athletes prefer to enhance their performance by practicing in regions of high altitude as this enhances their performances by  1 to 2 percent. The reason behind their claim is that at higher altitudes less oxygen is drawn per breath as compared to the oxygen drawn per breath in lower altitudes.
