During the broadcast of Sunday's Indianapolis 500, fans watching on television will be able to see just how much physical strain is put on a driver's body during the race.

ABC has outfitted James Jakes and Sage Karam with sensors near the base of their hearts that will report real-time telemetry, including heart rate, respiration and calorie burn rate, as their cars careen around the speedway at more than 220 mph.

The system was developed by Dr. Terry Lyles, an expert in human performance, stress management and life coaching who works with top teams in IndyCar, NASCAR and sports cars.

ESPN analyst Jerry Punch said the idea is to show how the stress on a driver changes as the race evolves, particularly during a wreck or the intense final laps.
