Will the activity tracker make you faster?


Will the activity tracker make you faster?

Renee Metivier Baillie, 33, prefers to use some kind of activity to track “gadgets” more than ever, but she finds them dazzling. The marathon runner who ran 2:27 in Chicago in 2012 was overworked a few years ago and now thinks some of the data on her wrist is useful.

“I’ve written down the quality of my sleep and how I feel the next day after exercise. But I started to think hard data would be better. “On Christmas Eve last year, Belgium had a 2-34 match. “My dream gadget will track actual sleep, not just how much I am in bed. It adds up my daily resting heart rate so I can see the trajectory of my rest and recovery time, “she said. “Thinking about this lately, I’ve been thinking, ‘wow, I want one. ‘”

Is there a small tool for a competitive runner-up? You would think so, from the public hype around the activity tracker. According to a January 2015 report by consumer product analyst NPD group, more than one in 10 U.S. adults wear a wrist tracker. Fitbit, a device on most wrists, raised $732 million in a public offering in June.

There’s never been so much information about personal health. The apple watch, which debuted in April, drew a full-day heart rate, calories and movement. Fitbit puts all this together with GPS. The Microsoft band has increased the exposure of ultraviolet light. Intel’s basic chart shows persistent skin temperature and sweat reactions, although manufacturers rarely explain why these are important.

However, for competitors, many of the available devices are inadequate in design and accuracy. Most are designed to encourage beginners to work harder and longer to chase a suspicious target of 10,000 steps a day (about seven miles of running). In contrast, well-suited runners tend to find the opposite accurate cues when to back down to prevent injury and overtraining.

When it comes to accuracy, most trackers skip a beat. Apple watch, Fitbit and other wrist – type HR players found that pulse rate sensors were unreliable during strenuous exercise. (only Mio and its partners, TomTom and Garmin, received a positive evaluation when they wore the wrist heart rate when they wore it.)

That’s why NPD analysts see a shift. The category of activity stalkers – basically a glorified pedometer – will soon become a more complex product. On the one hand, smartwatches, the smart phones on the top of a watch like the apple watch. On the other hand, sports performance wearable devices. These precise and expensive sports equipment will eventually provide more useful guidance in terms of speed, calories, heart rate, sleep, stride length and other data points.

For serious runners, the current search for technical tools is a mixed game. For example, Michael Wardian, 41, often sees a watch on each arm. “Yes, I look like a fool,” said marathon runner and the world’s 500, 000 national champions. “I need a Suunto altimeter, a barometer and a GPS. And I wear Mio’s heart rate. “(Suunto and Mio sponsor Wardian for free products.)

The accumulation of this technology began several years ago. Wardian USES the heart rate to adjust the early part of the game and then restores it. For Wardian, the latter is obviously very important, for example, three consecutive game at the weekend to run for three weekends in Boston (house), big sur (2:34), wings of life, and 45 miles of Melbourne Australia.

A few days later, Wardian monitored the small screen of his resting heart rate. That way he knows when he can charge ahead of time. “I used to think I didn’t need a heart rate or any garbage. “Timex is good,” he said. “But my playing time has been stable and I can’t rest at 2:30. I feel like I’m already complacent.

Some athletes began to have great hopes for the use of technology tools, but ultimately did not think it suited them. Triathlete Jesse Thomas, 35, is a Stanford university student with a 3,000-meter handicap (public relations ratio 8:35). He tracked sleep, the morning heart rate, and the detailed pace of the past, but also stopped short of attention. “These tools were very useful when you started, but now that I’m familiar with my body and my training methods, I can only provide one check-in procedure,” he said. “I don’t need objective things. I can wake up and know when I’m not feeling well. ”

Alex Willis, 27, disagrees. The university’s 5,000-meter runner, a few years ago, became a triathlete, looking for meaningful data points. “Athletes sometimes go too far – you can push yourself too hard or not enough,” says Willis. “Coaches can provide this objectivity, but some good tools can provide extra light bulbs for what’s going on.”

So Willis wakes up every morning with a sticky electrode on his forehead and another on his palm. He stood still for 10 minutes, and the sensor passed the dc voltage to his cell phone, according to the brain fatigue measured by supplier Omegawave. This “omega” signal shows Willis preparing for the day’s hard work. In addition to the widespread use of team sports, the technology is little known. Although recent independent studies have shown that science is not enough, Willis says feedback is crucial.

Willis recently had a bad morning, calling his coach, Trista Francis, to cancel. But omega wave is 100% ready, so he exercises. Francis says this is one of the most successful training days in recent memory.

Some athletes go further in the data’s desire. Runners on the so-called “heart rate variability (heart rate variability) or more interested in heart rate variability (HRV), HRV is a kind of way to analysis the heartbeat interval. According to a study in April 2014 in the Scandinavian journal of medicine and sports science, the number of heart beats is the key to diagnosing overtraining. Others wear the specific biological measurement data of wearable sensor body, such as heart rate patch (AmpStrip), breathing and muscle activity shirt (Athos), and lactate threshold calf sleeve (BSXinsight).

Many of these require further studies to test their effectiveness. Until their prices become more readily available (a full Omegawave system is currently running at $30,000), runners might be able to improvise on store shelves. They want to keep track of their ideas. A 2014 study in the international journal of exercise physiology and kinematics found that elite cross-country skiers reported an almost perfect match for their heart rate. This reminds us that, just as we may need better electronic tools to help us track our activities, we can’t give up all of our most powerful internal compasses.
