A local doctor is reflecting on his contributions to fitness and soccer. He developed a test to measure cardiovascular health. This test is still widely used today, including in schools.

The doctor's work has had international impact, with a notable example being his training program for a Brazilian soccer team. Soccer players can run long distances during a match, which can be particularly challenging in hot weather.

Further information about the doctor's achievements and contributions to fitness is available from NBC 5 Dallas-Fort Worth.
