Latest devices creating safer, more efficient home training sessions

INDIANAPOLIS－Darius Leonard works relentlessly at his rural South Carolina home to prepare for another football season. He's also wary of pushing too hard, knowing a minor injury could become a major setback given the dearth of medical experts in his area.

So when in doubt, the Indianapolis Colts star confers with his coaches, who are creating safer, more efficient individual workout programs based on data collected the past few weeks.

It's all part of a changing NFL world: high-tech devices supplanting old-school creativity.

"We are getting a ton done," Colts coach Frank Reich says. "With the technology today, they all have heart rate monitors, so they do their workouts, it's all logged, it all kind of shoots to our system. This isn't, 'Hey, I'm watching you.' This is, 'Hey, I'm interested in you.' I'm a little bit of a numbers guy, so I like to see these charts. Then I'll show them to the team."

That fits neatly into the new guidelines for this year's revamped offseason program, too.

Teams can conduct classroom instruction and on-field activities through Zoom meetings or similar apps instead of at their facilities. They can meet virtually as much as four hours per day, four days per week.

Players also can voluntarily wear monitors to track workouts. Teams can send up to $1,500 to each player to purchase equipment.

Not everyone has followed the same script. New Orleans canceled its offseason program. But the Colts are taking advantage of their allotted time. Reich estimates Indy spends half its time in meetings and the rests monitoring workouts.

Technological advances are helping everyone cope with the COVID-19 pandemic.

"I understand a lot more about the NFL now than I did 10 years ago," new Dallas Cowboys backup quarterback Andy Dalton said, comparing the difficulty he faced during the 2011 lockout with today's circumstances. "So I guess the advantage now is there's still these virtual meetings, so you're able to connect and talk through the offense and talk through different things, stuff that I didn't have my rookie year during the lockout."

Social media also plays a part.

Detroit Lions coach Matt Patricia recently reminded running back Ty Johnson about training safely－after watching a video of Johnson pulling a Jeep while wearing a helmet.

"Obviously, I'm pretty sure there was someone in the car to hit the brakes in case he slipped," Patricia said. "I go to safety first. I mean it's a Jeep, so once you get it moving, the ball bearings kick in and the tires go. Some of that, I was busting his chops about."

Companies such as WHOOP and Myzone could become game changers even after things return to normal.

WHOOP, an online fitness company, partners with the NFLPA to provide wearable monitors for players. Nearly 1,000 players have used the service over the past three years as well as teams from Major League Baseball, the NBA, NFL and Major League Soccer.

The waterproof device can be worn around the wrist or bicep and tracks heart rate and strain during workouts and recovery periods. In addition to measuring heart-rate variability, resting heart rate and respiratory rate, it provides information about sleep performance to give coaches the necessary information to ensure safe, efficient workout plans that won't overstress the body.

"If you go too far and keep training in a state where you're not recovered, you're not making physiological gains at that point. You're just digging a hole," said vice-president of performance Kristen Holmes, a former US national field hockey player and NCAA title-winning coach at Princeton. "It's not about more and more and more. It's about being smart and managing load."

The results may even help in the fight against COVID-19. WHOOP has information showing customers who tested positive saw a spike in their respiratory rates just a few days before the onset of symptoms.

Zebra Technologies has been using computer chips in shoulder pads and practice shirts since 2014.Now it has installed them in footballs. Radio transmitters at stadiums and practice fields transmit data that company officials say can track measurements within six inches of actual distance.

The results often appear on television broadcasts: how far or fast a player ran; how far a ball was thrown; or how much separation a receiver had from a defender. Those numbers came in handy when most pro days were canceled because of the pandemic.

"Not only did we track the Senior Bowl game, but we tracked all of the practice sessions. We captured all of the player information that week," said John Pollard, vice-president of Zebra sports business development. "The teams apply it as a tool like any other training process or mechanism they may have in place. It can help with things like rehab, too."
