Analysis

Your heart rate data does contain valuable information. We derive a.o heart recovery figures and HRV plots on request

Graphical representation

In this abstract you´ll find a more profound explanation of the ten small figures as presented in the file called ´Features´. These ten small figures have been generated based on the 8640 heart frequency measurements that your device is collecting. Out of these 8640 measurements we derive 178 so called features of which 10 most important features are represented in this plot. We could also make plots of the remaining features but these are less ´logical´ and quite difficult to relate to known physical parameters. But on request we can plot these remaining features and send them to you.  So, the 10 most important features are plotted in one figure. We will explain each of these 10 features in more detail in the 10 chapters below.

Figure 1. Minimum heart rate

The Minimum heart rate is the lowest value in one day that we retrieve from your device. Most data subjects (clients) show minimum values off 55 beats per minute (BPM) in average. But we encounter also values reaching towards 40 BPM as an ultimate low. But also minimum heart rate values exceeding 65 BPM are received. Meaning that for certain data subjects the heart rate never reaches values below 65 BPM. In general a low minimum heart rate is considered to refer to a healthy heart and a good heart condition.

Figure 2. Maximum heart rate

The Maximum heart rate is the maximum value we receive each day from your device. The maximum heart rate ranges from 120 BPM up to 185 for young data subjects with supreme heart conditions. Cardiologists calculate absolute maximum values being 220 minus the age +/- 10% depending on personal factors. Healthy people can touch this value several times a week with serious effort. Data subjects suffering from heart diseases should consult their cardiologist before trying to reach these maximum values.

Figure 3. Average heart rate

This is the mathematical mean of all heart rate measurements of one day. Values range from 50 to 85 or even higher. A low Average heart rate refers in most cases to very low night height rates. Well trained data subjects reach values of 40 BPM or even lower at night.

Figure 4. Standard Deviation

This standard deviation is a mathematical function often applied in statistics. It can be explained as the variation of the heart rate around the mean. With this explanation it can also be understood that the standard deviation also depends somehow on the difference between minimum and maximum heart rates. When the heart rate distribution is considered as a statistical normal distribution than 69% of all measured heart rate values lie in the range of your average HR minus the standard deviation and the average HR plus the standard deviation. For young data subjects we've seen standard deviations of 25 and higher. More senior data subjects show values of about 10.

Figure 5. Total heart rate samples

Every day your device collects 8640 heart frequency values. Because every device needs also some charging time and because most people don't wear the device when taking a shower of when bathing nobody manages to reach a 100% coverage. Next to that most devices also seem not to manage to make successful measurements all day long because of bad contact between skin and device. From all data we've collected so far we've not seen data collections exceeding 7.700 measurements a day. This equals a success rate of 90%. We consider this 90% as a kind of a maximum. We challenge our data subjects of course to succeed this coverage. Reaching high success rates is important for the academic research we are preparing for. A high density of successful measurements is important for statistical analysis because data strings with many erroneous measurements is omitted in several calculations.

A minimum condition to reach high success rates will be that the devices is worn day and night. That might be a matter of adaptability.

In the next 5 colored plots we present the number of intervals of 10 second each, that your heart did operate in heart rate zones as specified by Mr Karvonen. The Karvonen formula is a mathematical formula that helps you determine your target heart rate (THR) training zone. The formula uses maximum and resting heart rate with the desired training intensity to get a target heart rate. The resting heart rate is a standard value that your device manufacturer presents to you in the device App.

Figure 6. Healthy Heart Zone 50-60

This green bar figure presents the number of 10s intervals in the 50%- 60% range of your Max HR.

This is the easiest and most comfortable activity zone. So a number of 600 in this zone means that you've had 6.000 seconds training benefit in this zone. That is equivalent with one hour and 40 minutes. This is an easy and comfortable zone to exercise in. It's considered to be the lower end of the moderate-intensity zone. Your workout in this zone is less intense and won't give the most cardio respiratory training benefits. But studies have shown that it works to help decrease body fat, blood pressure and cholesterol. In this zone, the body derives its energy by burning 10 percent carbohydrates, 5 percent protein, and 85 percent fat. Walkers are often in this zone unless they press themselves to walk faster. If you exercise in higher heart rate zones, taking a healthy walk in this zone is a good way to enjoy an easy recovery day while still being active.

Figure 7. Weight management zone 60-70

This yellow bar figure presents the 10s intervals in 60% - 70% of your Max HR zone.

You are considered to gain muscle mass, lose fat mass, strengthen heart muscle. Your muscles burn fat, your fat cells increase the rate of fat release and increase in the number of mitochondria in the muscle. This is the higher end of the moderate-intensity exercise zone. You will be breathing heavier but will still be able to speak in short sentences. You get the same health benefits and fat-burning benefits as the healthy heart zone. An example of a workout in this zone is a brisk walking workout.

Figure 8. Aerobic Zone 70-80

This is the orange figure. The aerobic exercise zone is the intensity at which your body is using its aerobic metabolism system to produce energy from fat and glycogen. The aerobic heart rate zone is from 70 percent to 80 percent of your maximum heart rate. You are now in the vigorous-intensity zone. You will be breathing very hard and able only to speak in short phrases. This is the zone to aim for when training for endurance. It spurs your body to improve your circulatory system by building new blood vessels and increases your heart and lung capacity. Aiming for 20 to 60 minutes in this zone is believed to give the best fitness training benefits. Meaning that the orange bar should reach values of 120 up to 360. In the aerobic zone you burn 50 percent of your calories from fat, 50 percent from carbohydrate, and less than 1 percent from protein. An exercise in this zone stil feels comfortable, you will break a sweat but no anaerobic burn sensation. The exercise benefits are: Improved overall functional capacity with increase in the number and size of blood vessels, increased vital capacity, respiratory rate, max pulmonary ventilation, pulmonary diffusion, increase in size and strength of the heart, improvements in cardiac output and stroke volume. You would typically be in this zone by running or cycling, but you could achieve it by race walking or walking fast for an aerobic walking workout.

Figure 9. Anaerobic Zone 80-90

The anaerobic heart rate zone is 80 percent to 90 percent of your maximum heart rate. You will be unable to speak except a single, gasped word at a time. This intense exercise will improve the amount of oxygen you can consume: your VO2 maximum. This exertion level takes you to the limit where your body begins to produce lactic acid. Runners, cyclists, and race walkers use this zone to build their ability to go even faster. Workouts in this heart rate zone should be in the 10-20 minute range or part of an interval training workout. This means that your red bars should range from 60 to 120 at least some days of the week. You burn more calories per minute than with the lower heart rate workouts, as you are covering more distance per minute. The body burns 85 percent carbohydrates, 15 percent fat and less than 1 percent protein in this zone. High total amount of calories burned during exercise, high carbohydrates as source of calories. Improved VO 2 and higher lactate tolerance

Figure 10. Performance RedLine Zone 90-100

The pink bars are top of the bill and represent 90 percent to 100 percent of your maximum heart rate. You can't go any higher, and most people can't stay in this zone for more than a few minutes. A bar of height 6 represents one minute. You will be unable to speak except for gasping single words. This zone should only be used for short bursts during interval training, where you work intensely for a minute and then drop back down to a lower intensity for several minutes, and repeat. While you burn lots of calories per minute in this zone, 90 percent of them are carbohydrates, 10 percent fats, and less than 1 percent protein. This zone is ONLY for the VERY HEALTHY & FIT!!! Spending too much time in this zone, even for elite athletes can be painful, cause injuries and lead to over-training, which leads to poor performance! You should consult with your doctor to ensure you can work out at such a high heart rate safely.

Varying Your Workout Which zone should you work out in? It is best to vary your workouts for length and intensity and allow a recovery day between days of intense exercise in the aerobic, anaerobic, and red-line zone. A training program will often have shorter workouts of higher intensity two to three days per week, alternating with a recovery/rest day.

Target Heart Rate = ((max HR − resting HR) ×Desired Intensity in %) + resting HR

You can roughly estimate your max HR using the traditional formula 220 minus your age. You can get different fitness benefits by exercising in different heart rate (HR) zones. The five exercise zones presented by LorAIne are based on percentage ranges of maximum heart rate as specified according to Karvonen. In each zone you will feel a different level of exertion and your body will be burning a different percentage of carbohydrate, protein, and fat.
