An athlete’s death is one thing, but the deaths of a family member or a teammate in a sport that is supposed to be family-friendly and safe has become another.
The number of people injured in a pentathlon accident, including death, has risen from more than 300 in 2013 to more than 800 in 2016.
The death toll climbed to 7 on Tuesday, and officials announced Wednesday that at least three more people have been killed.
The toll in the four years to March 2017 was 8.
That compares with just 3.4 deaths in the first four years of the Olympics.
There are many factors at play, but some of the trends are clear: Pentathletes are not as likely to die from the injuries sustained in an accident as the general population, according to a recent study by the American Academy of Pediatrics.
The injury rate is also higher for men, especially those competing in long distance races.
“It’s a concern to the academy that there’s so little data to draw conclusions about this,” said Dr. Jonathan Coyle, director of sports medicine at the Cleveland Clinic Sports Medicine Center.
There have been more than 6,600 fatalities in Olympic events, and there have been nearly 2,500 serious injuries.
Most of the deaths were related to falling off objects or from falling onto people.
The sport has been plagued by safety problems and safety-critical injuries.
Officials said the Olympic champion, Ryan Lochte, was the victim of a hit-and-run in Rio, but Lochte has since denied being involved in the accident.
Many athletes who have been hurt or killed in the past year or so have been found dead.
A 19-year-old woman was found dead in a hotel in Rio on Aug. 1, 2016.
She had been hit by a vehicle and died from her injuries.
On June 25, a 17-year old student died in a crash while competing in a field race in the Pan American Games.
He had suffered a broken collarbone, a fractured pelvis and a broken leg.
A 16-year, 18-year and 20-year Olympic gold medalist, Ryan Murphy, was found fatally shot in a swimming pool in Mexico on Aug
