SAN FRANCISCO (AP) – The laptop screen showed that Cody Doolin’s heart rate had reached the red zone, meaning he was giving his maximum effort during a recent basketball practice at the University of San Francisco.
The freshman guard is one of the team’s hardest workers and among its fittest players, typically burning 1,700 calories over the course of a 40-minute game. These days, the coaches know this not just based on a hunch but because they have scientific evidence to prove it.
San Francisco’s men’s basketball program invested $10,000 this season for its athletes to wear heart rate monitors in both practices and games, and even for workouts in the weight room.
