Phillip Laster Jr., a lineman who played for a top Mississippi high school, had collapsed on the field during an August 2022 practice. At the time, the family says the heat index was 102 degrees (38.9 degrees Celsius) on the football field.“They kept compressing his chest trying to bring him back. No response, no response. Never a heartbeat,” said Laster, recalling how she dropped her purse, called her husband and started praying.

“I said I was going to call all the prayer warriors and bring my son back. I wanted him to come back,” she continued. “At that point, it was just an unbelievable moment. I can’t believe my son was gone. I could not believe it ... I was in a state of shock ... that he died ... at football practice.”

“Runners and athletes are at reduced risk of having not only cardiac arrest, but all forms of heart disease compared to non-runners,” said Dr. Aaron Baggish, a professor at the Université de Lausanne and former medical director of the Boston Marathon.Spectators cheer on runners as they compete in the Falmouth Road Race, Sunday, Aug. 18, 2024, in Falmouth, Mass.
