Objective: Exercise-induced cardiac dysfunction and corollary biomarker release have been documented following long-distance running events. To what degree these processes occur during shorter distance running events is unknown.
Methods: 72 healthy recreational runners (54% male/46% female) recruited by age (group 1 (18-20 years old, N=19); group 2 (45-50 years old, N=27); group 3 (70-75 years old, N=26)) were studied with echocardiography and biochemical profiling during participation in a 10 km running race.
