Fitness is not only about being physically fit and healthy but it is also about improving the quality of being suitable to fulfill a particular role or task. Now-a-days, fitness is getting popular among all the generations and people are getting serious about their fitness as it brings out a healthy physique in them.
How Fitness Tracking Bands look
It is an activity tracker, also known as a fitness tracker. It is a device in the form of a band for monitoring and tracking fitness-related metrics such as distance walked or run, calorie consumption, and in some cases heartbeat and quality of sleep. It looks like a bracelet with the features of a watch and fitness tracking devices as it sits quietly on your wrist: counting up your steps, monitoring your sleep, and calculating the difference between a light jog and a mad sprint.
Performance of Fitness Tracking Bands
Fitness tracking bands are available both with and without display. A couple years ago, fitness bands were basically glorified step counters worn on your wrist. Now, they’re doing everything from measuring your heart rate on a run to warning you to get out of the sun. Even though fitness bands are fairly simple compared to full-blown smartwatches, a growing number of sensors crammed inside has turned them into complex labs on your wrist.
Accelerometers: The most common instrument for Fitness Tracking Bands
It is an instrument for detecting and measuring vibrations and accelerations. It is the most common and basic instrument included in a fitness tracking band. It can be used for several things, but is mainly put to work counting steps. By measuring orientation and acceleration force, they can determine whether the device is horizontal or vertical, and whether it’s moving or not. Not all accelerometers are created equally. You will find both digital and analog ones will only have two-axis, while three-axis sensors can measure their position in three dimensions. At this point, most fitness tracker bands use fairly advanced accelerometers for increased accuracy.
One of the decades-old technology is GPS, but its appearance in fitness tracking bands is relatively new as the chips are becoming more efficient. The GPS receiver receives a high-frequency, low-power ratio signal from the satellites. The time it takes for a signal to reach your wrist can be translated into your distance from the satellite, which can be translated into precise coordinates with data from enough satellites. GPS chips continue to get better at handling battery usage, but GPS is still fairly power hungry compared to other sensors.
Heart-Rate measuring Monitors
Fitness tracking bands have an optical heart-rate monitor in it, that measures your heart rate using light. An LED shines through the skin, and an optical sensor examines the light that bounces back. Since blood absorbs more light, fluctuations in light level can be translated into heart rate. This is a process called photo plethysmography.
Thermometers in Fitness Tracking Bands
As a basic thermometer provides valuable information by way of your skin temperature. Rising skin temperature can indicate to a fitness tracking band that you are exerting yourself, or if your heart rate is not rising accordingly, that you might be getting sick.
Sensors: Ambient light, UV sensor
Fitness tracking bands work because of sensors. A fitness tracker band uses ambient light sensor to automatically dim its screen at night and brighten it in the sun and it also detects the time of day. UV sensors tell it when you may be absorbing harmful UV radiation (usually from the sun). The software compares this data to the values recognized by scientists to be harmful, and warms you to get out of the sun if you’re likely to burn.
Fitness Tracking Bands are great for fitness freaks as it is a wrist band and easy to carry around. It helps us in getting physically fit and warn us from outer radiations.
