According to Wikipedia, GPS means "The Global Positioning System (GPS) is a space-based global navigation satellite system that provides reliable location and time information in all weather and at all times and anywhere on or near the Earth when and where there is an unobstructed line of sight to four or more GPS satellites."
A network of between 24 and 32 satellites send continuous microwave signals to the Earth. These signals can be
chosen up by a GPS receiver anywhere on the Earth to consider three-dimensional position, velocity, and time in order to determine present location. The actual application of the GPS technology is what leads to such things as navigation systems, GPS tracking devices, GPS surveying and GPS mapping. GPS in itself does not provide any functionality beyond being able to receive satellite signals and calculate position information. And it does that astonishingly well!
Total energy expenditure is the amount of energy spent to act an activity. Energy expenditure, calculated in calories, is the energy necessary to maintain constant conditions in the body.
Your daily energy expenditure, or basal energy expenditure is the minimum correspond of calories needed to exist, or the minimum number of calories one should eat each day to maintain weight.
For a given body weight, energy expense during physical activity can be determined by tracking speed, slope, and duration of physical activity. GPS technology offers benefits for assessing physical activity by tracking the exact location of individual through time.
This permits the prognosis of an individual's pace (time spent in increments of physical activity) as they move both horizontally across the scene, as well as their altitude change (slope). These measurements can then be transformed into an measurement of energy expenditure.
GPS and fitness technology have been integrated into single devise, commonly named a GPS fitness unit or a GPS watch, which not only records location, but also computes energy expenditure (kcal/min). These GPS fitness units can path fitness advancement and record and can be operated during a variety of outdoor activities including: walking, hiking, running, and cycling.
That's how GPS watches assist individuals monitor speed, distance, pace and calories burned while training.
The GPS watches must to be recharged. The battery time of a GPS watches is usually between 10-13 hours. With a battery life this long it means you get many workouts in before you have to recharge the watch and the data stored in the GPS watch is not destroyed even if you let the battery end.
Some of the newest and most attractive GPS watches are the Garmin Forerunner 110, Garmin 205, or Garmin 305 -these watches have many available features.
There are also training assistant capabilities accessible on the Forerunner, making reaching your data basic and carefree.
Some of the best running watches offer also a virtual personal trainer. Studies have proved that when trainers track your progress you will be more able to stick with your workout regimen and accomplish at a greater level than when you train unaccompanied. The virtual training partner will act as a person trainer to guarantee your success.
