Industrial athletes are firefighters, police officers, FedEx drivers, and warehouse workers — people who depend on physical fitness and strength to do their job. When these people have heart attacks, they need more intense therapy before they can get back to work.

More than half a million heart surgeries are performed each year in the U.S. For many, cardiac rehab is helpful but it’s not enough to get them back to work. Now, there’s a different type of therapy. It’s rehab for the real world.

It looks like scuba instructor Dennis Maurer is gearing up for a dive, but this is rehab for the 60-year-old who recently had two heart surgeries.

“There was about an 80-percent blockage in one of the arteries.”

Instead of standard rehab, Dennis chose Industrial Athlete: a rigorous program designed to help heart patients get back to their physically demanding jobs.

“Basically, we’re trying to make the exercise prescription as close to real life as possible.”

They carry hoses up stairs, swing sledge hammers, shovel rocks, and even practice hitting dummies.

Firefighters, police officers, athletes, farmers, and auto workers regain the strength they need by doing activities they do in their jobs.

“We believe that we need to see them at the level they are going to perform at their job or their sport.”

A recent study found attending rehabilitation is associated with a 46 percent lower risk of death. But a recent study found only 14 percent of heart attack patients use rehab.

Researcher Jenny Adams says one of the problems is traditional rehab isn’t personalized.

“We have a 90-year-old woman in here. In the old days, we would give her the same prescription that we would give a 30-year-old firefighter, and we just want to stop that,” Adams said.

Here every patient gets a different workout.

“After three months of working out and on rehab and after the surgery, I can walk on the treadmill. I can go up ladders. I can carry weights.”

Standard cardiac rehab is very conservative. Patients ride stationary bikes, walk on treadmills, and lift very light weights. Adams believes the program at Baylor hospital is the only one of its kind in the nation. It recently won the Innovation Award from the American Association of Cardiovascular and Pulmonary Rehabilitation.
