    Wearable Trackers Estimate Fitness Levels Without High-Intensity Exercise

    Researchers developed a method to estimate cardiorespiratory fitness levels that could be applied to data acquired by wearable fitness trackers during daily activities. This could facilitate tests for those who have low exercise tolerance and may reduce the need for fitness tests under medical supervision.

    Cardiorespiratory fitness is the ability of the cardiovascular and respiratory systems to supply enough oxygen to the muscles during physical activity. People with low cardiorespiratory form may have an increased risk of heart disease, heart attack or stroke. Testing the amount of oxygen that the body uses during exercise (VO2max) can evaluate these risks and also function as a preventive measure. However, people generally have to train until exhaustion to measure VO2max and such tests require medical supervision and specialized equipment. In addition, it may not be safe for anyone who has to undergo cardiorespiratory fitness tests to exercise at maximum effort. Methods that use low intensity (submaximal) exercise do not always provide accurate results like maximum tests.

    The Reliability of Fitness Trackers: Do They Provide Accurate Data?

    In the modern world of high technologies, few can imagine their lives without devices and gadgets that make our life easier in many ways. The sports market is not an exception. It is full of different devices that are targeted as tools for more effective workouts. Fitness Trackers, that have become very popular in the last few years, will help you to monitor such metrics as burnt calories, steps, heart rate, and pulse. Nevertheless, are the measurements trustworthy? Let’s find out.

    1.  Steps

    Professionals argue that the majority of fitness trackers measure steps throughout the day properly and provide accurate results. There can be some exceptions though. For example, the number of steps of people who walk to slowly can slightly differ from the real picture. Nevertheless, professionals also recommend wearing a hip tracker for more accurate results as wrists ones can detect a lot of hand movements.

    Reasons to Always Monitor Pulse Rate While Running

    There is no arguing that sport should be an irreplaceable part of like for each person who wants to stay healthy and live a long life. However, professionals and doctors always recommend doing thorough research before any activities to avoid doing any harm. For example, not all people know that monitoring the pulse is a must for several important reasons. 

    1.  It helps to determine the intensity

    People should realize that pulse rate cannot and will not always be the same. For example, in your resting period, the pulse will be lower than during running. Moreover, running can differ in intensity. And that is why pulse rate will be a good indicator of the quality of your running.

    2.  It can prevent fainting and other health issues
