Best Running Watches- What Do They Really Do?
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 communicate continuous microwave signals to the Earth. These signals can be
selected 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 very well!
Total energy expenditure is the amount of energy used to perform an activity. Energy expenditure, calculated in calories, is the energy required to maintain constant conditions in the body.
Your daily energy expenditure, or basal energy expenditure is the minimum correspond of calories needed to live, or the minimum number of calories one should eat each day to maintain weight.
For a given body weight, energy expenditure during physical activity can be determined by search speed, slope, and extent of physical activity. GPS technology offers advantages for assessing physical activity by tracking the exact location of individual through time.
This allows the calculation 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 variation (slope). These evaluations can then be changed 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 record fitness development and history and can be used during a diversity 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 need to be recharged. The battery life of a GPS watches is usually between 10-13 hours. With a battery life this long it means you get several workouts in before you have to recharge the watch and the data stored in the GPS watch is not wasted even if you let the battery end.
Some of the advanced and most popular GPS watches are the Garmin Forerunner 110, Garmin 205, or Garmin 305 -these watches have many available features.
There are also training assistant capabilities available on the Forerunner, making reaching your data basic and carefree.
Some of the best running watches give also a virtual personal trainer. Studies have shown that when trainers track your advancement you will be more able to stick with your workout regimen and succeed at a greater level than when you train alone. The virtual training partner will react as a person trainer to secure your success.
