{"product_id":"hr-500-hrt","title":"KALENJI HR 500 HEART RATE RUNNING WATCH - WHITE","description":"\u003cp\u003eWe have designed this product for runners looking for a simple watch with a heart rate monitor on the wrist and a calorie counter.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003ch4\u003eWHY RUN WITH A HEART RATE WATCH?\u003c\/h4\u003e\u003cp\u003eHeart rate is measured in BPM (beats per minute). The more intensively you exercise, the faster your heart beats, and the more your BPM increases.\nUsing your resting heart rate as a reference, the HR 500 heart rate watch is capable of telling you what kind of exercise you are doing: Warm-up, Comfort, Endurance, Resistance, Max. Each level of intensity has a different effect on your body: comfortable exercise, weight loss, better endurance etc.\u003c\/p\u003e\u003ch4\u003eHEART RATE MONITORING AT THE WRIST\u003c\/h4\u003e\u003cp\u003eThe heart rate measurement on the wrist is a huge technological advance making heart rate watches simpler and more comfortable. For the last 4 years, our Research \u0026 Development teams have been testing different options for measuring the heart rate at the wrist.\nWe chose the optical heart rate sensor option for superior comfort while guaranteeing a good reliability of the signal.\u003c\/p\u003e\u003ch4\u003eRUNNING WITH YOUR HEART RATE TO SET THE PACE\u003c\/h4\u003e\u003cp\u003eAre you often out of breath at the end of a run? The HR 500 gives you real-time information so that you can adjust your speed and avoid getting too close to your limits. In the comfort zone, you should be able to speak while running. In the endurance zone, the exercise will be more intense, but you shouldn't get out of breath. In the resistance zone, you will get out of breath after a few minutes.\u003c\/p\u003e\u003ch4\u003eRUNNING WITH YOUR HEART RATE TO BURN FAT\u003c\/h4\u003e\u003cp\u003eDo you run to stay in shape? The \"comfort\" zone is particularly useful because it allows you to burn more fat and avoid getting out of breath. In fact, in this zone, your body is not under stress. It has time to burn fat properly to turn it into energy for your muscles.\u003c\/p\u003e\u003ch4\u003eFINDING TRAINING PROGRAMMES\u003c\/h4\u003e\u003cp\u003eThe heart rate of your training sessions can be sent directly to your Decathlon Coach session.\nDecathlon Coach is a free mobile app that guides you during your training sessions.\u003c\/p\u003e\u003ch4\u003eHOW ARE EXERCISE ZONES CALCULATED?\u003c\/h4\u003e\u003cp\u003eYour effort zones are automatically calculated according to your reserve heart rate (HRres = maximum heart rate - heart rate at rest).\nYour maximum heart rate is estimated according to your age and gender. By default, the heart rate at rest is 70 bpm.\nWarm-up: \u003c 60% of your HRres.\nComfort 60 to 70% of your HRres.\nEndurance: 70 to 80% of your HRres.\nResistance: 80 to 90% of your HRres.\nHard resistance: 90 to 100% of your HRres.\u003c\/p\u003e\u003ch4\u003eHEART RATE MONITORING AT THE WRIST: How does it work?\u003c\/h4\u003e\u003cp\u003eWhen you do exercise, such as running, your heart beats more quickly. The flow of blood through your vessels increases. The green light under the wristband enables the HR 500 watch to measure the blood flowing under your skin, which is used to obtain your heart rate. This optical sensor technology is completely integrated into the watch: Leave your heart-rate monitor belt at home!\u003c\/p\u003e\u003ch4\u003eIs an optical heart rate monitor less precise than a heart rate belt?\u003c\/h4\u003e\u003cp\u003eDuring our tests, we found that the optical sensor had an accuracy of more or less 2 bpm on average. The measurement is also a bit less reactive during interval training. We consider, like a lot of runners, that the advantages of having your heart rate on your wrist (comfort, simplicity, low weight etc.) largely outweigh the disadvantages.\u003c\/p\u003e\u003ch4\u003eHOW TO WEAR THE HR 500\u003c\/h4\u003e\u003cp\u003eTo guarantee an optimal heart rate measurement, the HR 500 heart rate watch must be worn on the wrist after the prominent wrist bone.\nThe sensor must be in contact with the skin, which means that the wristband must be properly tightened. Your optical heart-rate monitor will not perform as effectively if the watch is too loose. For more information, please watch our explanatory video at the bottom of this page.\u003c\/p\u003e\u003ch4\u003eDoes the optical heart rate monitor on the HR 500 work on all types of skin?\u003c\/h4\u003e\u003cp\u003eThe heart rate sensor technology on the HR 500 is designed for all skin colours and any amount of arm hair. On dark or tattooed skins, less light is reflected by the skin. In this case, the sensor adjusts by increasing the brightness of the emitted light or by adjusting the sensitivity of the light sensor. If however you encounter any problems, contact our team on our support website.\u003c\/p\u003e\u003ch4\u003eIs the optical heart rate monitor on the HR 500 suitable for all sports?\u003c\/h4\u003e\u003cp\u003eThe heart rate sensor technology on the HR 500 is ideal for sports involving repetitive movements such as running, walking or cross-training.\nFor sports involving unsynchronised movements like fitness sports, weight training, racket sports and team sports, you may observe errors in the readings.\u003c\/p\u003e\u003ch4\u003eMANUAL HEART RATE ZONES\u003c\/h4\u003e\u003cp\u003eIf you want to train in a very specific heart rate zone, you can enter a manual heart rate zone into the watch (in BPM or %MHR). A graphic indicator on the screen, along with a sound signal, will inform you when you leave the zone. You can also enter your resting heart rate and maximum heart rate yourself if you already know them.\u003c\/p\u003e\u003ch4\u003eCOMPARE YOUR RUNS\u003c\/h4\u003e\u003cp\u003eThe HR 500 watch gives you summaries of your previous runs. For each session, you'll find your run duration, your average heart rate and the number of calories burnt.\u003c\/p\u003e\u003ch4\u003eBATTERY LIFE \u0026 CHARGING\u003c\/h4\u003e\u003cp\u003eThe HR 500 jogging watch has a battery life of 2.5 days in heart rate mode and 30.5 days in watch mode. It can be recharged using the USB cable provided.\u003c\/p\u003e\u003ch4\u003eDimensions\u003c\/h4\u003e\u003cp\u003eUseful screen diameter: 25 mm\nThickness: 14 mm\nWeight: 34.4 g\u003c\/p\u003e\u003ch4\u003eWARRANTY \u0026 AFTER-SALES SERVICE\u003c\/h4\u003e\u003cp\u003eDECATHLON products include a 2-year warranty.
