What test should I use for this problem?

4. A group of exercise science researchers are studying the effects of caffeine on the endurance of athletes.
They recruit 9 individual competitive cyclists to take part of the study. On the first day of the study, the
researchers ask the cyclists to ride a stationary bike at the maximum resistance at a consistent speed for as long
as they can. The time to fatigue (i.e., giving up and ceasing pedaling) is recorded (in minutes and seconds).
Three days later after some rest, the cyclists come back in for another test. This time they are given a dose of
13 mg of caffeine and asked to repeat the same stationary bike test 30 minutes later. The time to fatigue (in
minutes and second) is again recorded.
