A Fitness Tracker is a waste of money?

Cyclist Peter Dumbreck marked new personal record in three days cycling. He uses a computer Garmin Edge 810, a heart monitor and a power meter.

Dumbreck says he is very satisfied by this device after seeing his power, etc. Updating data.

But for us, the rest? Do we know how many calories burn, how fast the heart beats us, and what steps do that keeps us motivated to do more exercise and to eat healthy? So are we efficient?

Last year, the University of Pittsburgh found that fitness trackers (fitness equipment and applications) were 'ineffective for weight loss. "

2-year study had involved 500 overweight volunteers. Everyone asked a diet with exercises, but only half of them were given fitness tracker to help.

The study showed that those who had these devices lost 3.6 kg, while those who had lost 5.9 kg.

"Trackers are a reliable measure of our activity, but we can not rely entirely on them," says Andrew Lane, professor of sports psychology at the University of Wolverhampton.

"We should not expect to simply buy it and that's it, we have some responsibility ourselves. Should get up off the couch and to make them 10 thousand steps a day "continued Lane.

He goes even further, saying that if not properly used, they can have negative psychological effects on us. "What happens if we do not consistently achieve the objectives we have set? us, then the opposite effect had thought, "says Lane.
