What is the average step of a person. N. Nikitin Geometry
Continuing the topic therapeutic walkdiscussed in the article "" as a way prevention and treatment and arthrosis of the joints. In order to correctly dose the load on your body by such an indicator as the distance traveled, you need to know, at least approximately, the length of the distance.
Average stride length
To determine the distance traveled, it is not necessary to go the distance with a tape measure. Enough to know average stride length. Multiplying this indicator by the number of steps taken per minute, and by the time taken to complete the entire distance, you will get the distance traveled.
If your course of movement for each lesson is approximately constant, having measured it once, you will use this data many times.
Example: The average step length is 0.5 meters. You take 105 steps in a minute. You go the distance in 60 minutes. We carry out simple arithmetic operations and get the distance you traveled: 0.5 m x 105 sh. x 60 minutes \u003d 3150 meters.
This option is possible: you do not spend an hour on therapeutic walking, but more. For example, 90 minutes. And you do not take steps 105, but 150.
In this case, we substitute new values \u200b\u200bfor these indicators into the formula. The result is a longer distance: 0.5 mx 150 sh. x 90 minutes \u003d 6750 meters.
How to measure stride length?
You can measure the length of your step very simply. Mark the line on the floor. It is not necessary to draw it. Just put a pencil on the floor. This will be an imaginary starting line. Take the second pencil in your hand. Stand on the “start” to the imaginary line right toes. Take a step forward through an imaginary start line. It should be of natural length - no longer and no shorter than your usual step.
Hold this position. Put a second pencil to the toes, which is in front. Measure the distance between the pencils. This will be the length of your step.
When such measurements are taken, often steps are taken of an unnatural length. Either shorter or slightly longer. To avoid the mistake, step again. Measure again. If you feel that the step length does not bother you, that it is familiar to you, convenient and natural, this will be the desired length of your step.
There is another easy way to measure your average stride length. Take a few steps in one direction. For example, five. Measure, as in the previous example, the distance traveled and divide it by the number of steps you took. This will be the desired value.
Example: You have traveled a distance of 2 meters. In doing so, 4 steps. We divide two meters by 4, we get the length of your step, equal to 0.5 meters.
Up to a millimeter, you do not need to calculate the step length. Such accuracy at walking within Exercise therapy (occupations by medical - physical culture) are not required.
The goal is achieved. Theoretically, you are ready for classes.
It remains only to choose the appropriate equipment. About this in the article "".
Walking is the most rewarding sport that we do every day. Even if the work is not related to physical labor, you still have to walk. Nutritionists and fitness trainers unanimously argue that simple walking helps to tidy up your figure and significantly lose weight, especially if you stick proper nutrition. In addition, regular walking helps strengthen the heart muscle and blood vessels, improves lung function and trains endurance.
No time for the gym - we go to work on foot
It is not necessary to have special electronic devices that will count the distance traveled. It is enough to know how many steps are in 1 kilometer to understand how much time you need to spend walking. Without expecting it ourselves, we spend a lot of calories on this simple process. And the more you move, the more you spend. In addition, we must not forget that this contributes to the active breakdown of fats. Therefore, knowing how many steps are within 1 kilometer, you can build an individual system for losing weight and improving your body. This is a very good incentive to start walking home after work on foot. And in a month you can completely lose a few pounds imperceptibly.
Walking can also be different
The length of steps for different people will be different. It depends primarily on the growth of a person. The higher it is, the longer the step, and therefore, the faster it will pass a certain distance. However, this is not the only point. The size of the foot, as well as the shoes in which the person walks, matters. For example, if you go in sports sneakers, then the stride length can be maximum, and even without accelerating the course, you will go a little faster. But for a girl in stilettos, the stride length will be much shorter, and this does not depend on the height of the person. When calculating how many steps are within 1 kilometer, one should not forget about such nuances.
Not so simple arithmetic
As you can see, just taking the final digit will not work, and therefore you will have to make some calculations. True, you can use the approximate formula, which states that 1 km - 1000 steps. However, it is not at all accurate. It is taken as the basis that in one step - about a meter, that is, in 1000 steps you will walk about 1 km. But the only option to get reliable data is to turn on any navigator and walk one kilometer, counting the steps.
We give approximate calculations by which you can find out how many steps are 1 km away. For example, take a person’s height of 175 cm. He will need to take 1377 steps to cover the required distance.
Increase the load
If you want to go walking in order to lose weight, then you definitely need to ensure a calorie deficit. In this case, you should know that just walking in the park, you will spend much less than if you are in a hurry somewhere. An athlete who uses a sports step will also work much more efficiently, with greater impact. When walking fast, the costs increase by about three times, which can be used for good. Significantly increases calorie consumption walking on stairs, cross country and uphill. Although there is a small snag. Speaking about how many steps are 1 km, it should be noted that when climbing uphill, the step length is reduced, which means that the initial calculations will already be incorrect. However, the effectiveness of such activities is increasing, and quality is much more important than quantity.
An alternative to fitness training
To have an excellent figure and excellent state of health, it is not at all necessary to visit any section. To do this, you don’t even need to know how many steps are 1 kilometer when walking. It is enough to simply refuse trips to the store, to visit and to work on public or personal transport. Instead, walk everywhere. Of course, it will be necessary to review the costs of personal time. However, a cheerful state and a fit figure will be a great reward for you. If you walk for 2 hours every day, and this is often your way to work and back, in just a week you will burn more than 200 g of subcutaneous fat. If you do not lean on fatty and sweet foods, and also do not overeat, these reserves will not be renewed. Therefore, after a few months, the result will be clearly marked on your silhouette.
How much do you need to go per day
We have already said: to be healthy, you must definitely go in for sports. And its simplest and most accessible form is walking. We tried to calculate how many steps are in 1 kilometer (meters, as you know, 1000, and about the same number of steps should be). However, the question immediately arises of how many kilometers need to be covered per day in order not to have health problems. Rather popular is the rule of 10,000 steps. This norm came to us from Japanese everyday life. However, questions again arise. And if a person ate a hamburger or ice cream, is it necessary to increase this rate? Or can you leave it the same?
In fact, this figure came to us from ancient times, when the Japanese traveled much more on foot, and their diet was much healthier. Therefore, it was only a guideline for a healthy lifestyle. Today, doctors are faced with the fact that for many people, even 2000 steps a day becomes problematic. It is for these people that the desire to daily overcome eight or more kilometers is the most significant. The bar should be raised gradually so that there is no temptation to quit this venture.
Sports and healthy eating
There is another point why doctors do not recommend untrained people to walk that much. Because a person can take the habit of walking 4 km in the morning and evening, but completely neglect the diet. Every day, 10,000 steps is very good for health, but if you eat them with a hamburger and drink cola, you will still gain weight.
Change the step to run
If you want to make training more intense, then go for a run. In this case, the respiratory system trains and hardens, there is a powerful influx of oxygen to all organs and tissues. Thanks to this, the body improves. Some novice runners are interested in how many steps are 1 kilometer when running. To find an average solution, one step in this case is equated to 1.5 meters. It turns out that the kilometer will fit in about 666 running steps.
It should be noted that since exercise stress increases, then the calorie consumption, respectively, will increase. When walking slowly, a person spends 3.2 kcal for each kilogram of his weight, then 4.5 kcal. And if you switch to running, then the flow rate increases to 10 kcal.
Instead of a conclusion
All of these methods can give a very significant error, so you can only approximately calculate how many steps are 1 km when running. And if you want to have accurate data, experts recommend using fitness bracelets. They put it on the arm, and it shows how many kilometers a person has traveled. Of course, there are many applications on the phone. They are free, but for the most part they work with large errors. So, the application can record a trip by car in walking, and another time it will not respond to your trips at all. Therefore, if you really use devices, it is better to choose professional devices.
When the hot days of summer come, it’s hard to stay at home. It's time to pack up and get ready for a vacation. The best rest is a camping trip, or excursions, during which you often have to measure distances. But a measuring tape or tape is not always at hand, and it’s useful to be able to do without them somehow, producing at least approximate measurements .
Measuring long distances is easiest in steps. In ordinary walking, we take steps of approximately the same length, and if you know their average length and be able to count, then you can make approximate distance measurements without a big mistake.
To do this, measure the distance of 20 m on an even place with a tape. Draw a line on the ground along the tape. Now go along the line in the usual step and count the number of steps taken. It is possible that the step does not fit an integer number of times over a measured length. Then, if the remainder is shorter than half the length of the step, you can simply fold it; if it is longer than half a step, the remainder is considered as a whole step. Dividing the total length of 20 m by the number of steps, we will learn the average length of one step. This number must be remembered so that, when necessary, make approximate measurements of distance.
By the way, the following old rule can be noted: the length of the average step of an adult is equal to half the distance from his eyes to the feet. There is a second rule: a person walks as many kilometers per hour as he takes steps in 3 seconds. But it can be proved that the rule is true only for a certain step length. Indeed: let the stride length x m, and the number of steps in 3 seconds. equally n. Then in 3 sec. the pedestrian does nx m, and per hour (3600 sec.) - 1200 nx m, or 1.2 nx km For this path to equal the number of steps taken in 3 seconds, there must be equality: 1,2nx \u003d nfrom where:
x \u003d 0.83 m.
If the step length depends on the person’s height, then the second rule is justified only for people of average height - about 175 cm.
Approximate measurements of medium-sized objects can be carried out as follows. If you pull a rope or stick from the end of an outstretched hand to the opposite shoulder in an adult male - this will be an approximate length of a meter. Another way of approximate measurements of the length of a meter is to postpone in a straight line 6 the distances between the ends of the thumb and forefinger, spaced as wide as possible (Fig. 1a).
Approximate measurements with bare hands can be turned into art: for this, you only need to first measure your hand and firmly remember the measurement results.
In the hand, first of all, it is necessary to measure the width of the palm, (Fig. 1b). In an adult, it is approximately 10 cm. Then you need to measure how great is the distance between the ends of the middle and index fingers, spread apart as wide as possible (Fig. 1c). Further, it is useful to know the length of your index finger, counting from the base of the thumb (Fig. 1d). And finally, measure the distance between the ends of the thumb and little finger when they are widely spaced (Fig. 1e).
Using this "live scale", you can make rough measurements of small objects.
Stride length - why do we need to know this value? While walking or running, we need to dose the load on the body, for this we need to know the distance traveled and the speed of movement. There are many devices for determining the distance traveled: pedometers, activity monitors, however, for some devices to work, you must specify the average step length in the settings. So in any case, you have to determine this value.
The stride length in people is not the same and ranges from 0.4 to 1 m. Usually, the stride length of a person of average height is 0.7-0.8 m.
How to measure stride length?
1. The length of your step can be relatively accurately determined by the formula for the dependence of the step length on growth:
L \u003d (P / 4) +0.37
LH - the length of one step in meters
P is the person’s height in meters.
For example, when a person is 1.75 m tall, his step length is LH \u003d (1.75 / 4) + 0.37 \u003d 0.8 m.
2. For each person, the step length usual for his walk has a more or less constant value.
To determine the step length, you can measure a distance of 10 to 20 meters. and go through it at the usual average speed. After that, dividing this distance in centimeters (1000 or 2000) by the number of steps taken, we will find the average length of our step.
For example: 1000cm / 12 steps \u003d 83 cm.
How to determine walking speed and distance traveled?
Knowing the length of your step, as well as the number of steps taken per minute, you can determine walking speedusing the table below.
For example, if a person walks 120 steps in 1 minute while his step length is 82 cm, then according to the table we determine the walking speed of 5.9 km / h.

When walking speed and time are known, it is not difficult to calculate the distance by multiplying speed by time. Also distance traveled can be calculated using the average stride length. Multiplying this indicator by the number of steps taken per minute, and by the time taken to complete the entire distance.
For example, a person spends 90 minutes walking, with a step length of 0.82 m. In 1 minute, he takes 120 steps, based on these values, we find the distance traveled:
A measuring ruler or tape is not always at hand, and it is useful to be able to do without them somehow, making at least approximate measurements.
Measuring more or less long distances, for example during excursions, is easiest in steps. To do this, you need to know the length of your step and be able to count the steps. Of course, they are not always the same: we can take small steps, we can also walk broadly if desired. But still, with ordinary walking, we take steps of approximately the same length, and if you know their average length, then you can measure distances in steps without a big error.
To find out the length of your average step, you need to measure the length of many steps together and calculate from here the length of one. In this case, of course, you can no longer do without a measuring tape or cord.
Pull the tape out of the blue and measure 20 m. Draw this line on the ground and remove the tape. Now go along the line in the usual step and count the number of steps taken. It is possible that the step does not fit an integer number of times over a measured length. Then, if the remainder is shorter than half the length of the step, you can simply fold it; if it is longer than half a step, the remainder is considered as a whole step. Dividing the total length of 20 m by the number of steps, we obtain the average length of one step. This number must be remembered so that, if necessary, use it for measurements.
In order not to stray when counting steps, it is possible - especially at long distances - to keep the count as follows. Count steps only up to 10; counting to this number, bend one finger of the left hand. When all the fingers of the left hand are bent, that is, 50 steps have been taken, one finger is bent on the right hand. So you can keep a score of up to 250, after which they start again, remembering how many times all the fingers of the right hand were bent. If, for example, after passing a certain distance, you bent all the fingers of your right hand two times and by the end of the path you have three fingers bent on your right hand and four fingers on your left, then you took steps
2 X 250 + 3 X 50 + 4 X 10 \u003d 690.
Here we need to add the few more steps that were taken after the finger of the left hand was bent for the last time.
Let us note the following old rule along the way: the length of the average step of an adult is half the distance from the floor to the eyes.
Another old rule of thumb relates to walking speed: a person walks as many kilometers per hour as he steps in 3 seconds. It is easy to show that the rule is true only for a certain step length and, moreover, for a rather large step. In fact: let the step length be x m, and the number of steps in 3 seconds is n. Then in 3 seconds the pedestrian makes n x m, and in an hour (3600 seconds) -1200 n x m, or 1.1 n x km. For this path to be equal to the number of steps taken in 3 seconds, equality must exist:
1.2 n x \u003d n, or 1.2 x \u003d 1.
From where x \u003d 0.83 m.
If the previous rule about the dependence of the step length on the person’s height is true, then the second rule, now being considered, is justified only for people of average height - about 175 cm.
To measure medium-sized objects, without having a meter ruler or tape at hand, you can do this. It is necessary to pull the rope or measure the stick from the end of the outstretched arm to the opposite shoulder (Fig. 319) - this is the approximate length of a meter for an adult man. Another way to get an approximate meter length is to postpone in a straight line ...
Our copper (bronze) coins of modern coinage can also serve a good service. Not many people know that the diameter of a penny coin is exactly 1 1/2 cm, and a nickle is 2 1/2 cm, so that both coins placed side by side give 4 cm. So, if you have several copper coins with you, then you can quite accurately ...
