Are you sitting down for this? You might want to stand up after you hear this.

woman stretches before run while tracking personal fitnessA study released in 2012 shows the more you sit, the sooner you’ll die. It found adults who sat for more than 11 hours a day had a 40 percent increased risk of dying within three years for any reason.

So the solution seems simple – stand up, walk around, go for a run. But it can be hard to remember, especially since some of us get paid to spend eight hours in chairs at work.

Enter wearable sports technology. Products like the Nike+ FuelBand, the Fitbit Flex, and Jawbone’s Up exist to solve this sedentary problem and help you track your fitness.

All three of those products are wristbands, which is the trend right now. They each look a little different, but the information they gather is similar.

The FuelBand wants to turn your day into a sport. You set a fitness goal, and then track your progress through a simple readout on the device.

For a more detailed look, users can open the accompanying app. Nike’s band stores your fitness information on the cloud, so you can access it on the go or pull it up at home.

Which isn’t all that unique. The Fitbit Flex also syncs wirelessly to your laptop and smartphone. Aside from visualizing your activity, Fitbit also sends you badges when you reach your goals.

Both bands keep track of steps taken and calories burned. The Flex also measures your sleep – how long you slept and how many times you woke up.

Jawbone Up’s also monitors your sleep, and even includes a silent alarm to get you out of bed in time for that morning run.

And skipping it isn’t advised with one of these on. The Up has an idle alert that will warn you whenever you’ve been inactive for too long.

That said, the Up, Flex, and FuelBand aren’t the most accurate measurements of activity.

Assistant professor Dr. Nate Meckes, put the bands to the test. Because they rely on accelerometers to measure movement, they can sometimes overestimate wrist action and under report lower-body movement, like standing or bicycling.

Still, Dr. Ray Browning, who published a similar study in May tells the New York Times, the devices might not be perfect yet…

“But for many people, they’re inspirational, and if using one gets someone to move more, then as far as I’m concerned, it’s serving a good purpose.”

That’s not good enough for UC-San Diego researchers, though. They’ve developed a sensor that uses your sweat – not an accelerometer – to measure physical exhaustion.

GigaOm reports it’s applied like a temporary tattoo but still has the ability to transmit data wirelessly. The sensor looks for increased levels of lactate, a chemical that builds in your muscles during physical activity.

And this wearable trend isn’t stopping anytime soon.

Just last month, a mind-monitoring headband received nearly three times its funding goal on Kickstarter. Melon, unlike the wristbands, aims to measure your focus and keep track of your mental health.

Which leaves Google Glass. Though not specifically meant for measuring physical activity, who knows what sorts of apps developers will create if this tech spreads.
