A sports scientist conducted an investigation to determine whether the type of music played during a warm-up affects athletic endurance. One group of athletes warmed up for 15 minutes while listening to high-tempo music (above 130 BPM). A second group of athletes warmed up for the same duration in silence. The sports scientist recorded the time, in seconds, that each athlete was able to maintain a sub-maximal run at 12 km/h on a treadmill before exhaustion.
