Video analysis of running barefoot and footwear

Saturday, March 20th, 2010

Running is a great fitness and weight loss, but how many know the riders, which can often result in chronic injuries. Shoe companies are constantly marketing their latest findings in the comfort of light shoes, against the effect of reducing pronation and energy conservation. Grid systems, air bags, smart chips and step their way into our monitors all running shoes. Everyone seems happy as a holder of large amounts of confidence for the shoes and the fact that the shoe company has made a detailed analysis, and offers a product that can improve performance, reduce the chances that the actual injury or even solve our current injury problems. This article in the Daily Mail http://www. BBC. co. uk/home/moslive/article-1170253/The-painful-truth-trainers-Are-expensive-running-shoes-waste-money. HTML is an excerpt from a new book by Christopher McDougall on injury prevention, running shoes and their demands and led to our current topic. We decided to test video analysis to influence how pronation shoes. We will show how to measure rearfoot pronation with his video camera. This measure is often used in the specialty running shoe store to help customers in choosing the right anti-pronation running shoes. We show as is, and measure pronation of an athlete running barefoot and with track shoes. The foot pronation occurs when the arch collapses and the foot turns outward. Caused by high forces, over pronation of the foot may require that is often associated with running injuries. Supination is the opposite of pronation, and occurs when the foot inward. To correct this film, we had to use a treadmill. It would be very difficult to obtain a coherent view of the foot and leg, if the athlete was running away from us, and farther with each step. With the theme on a treadmill, we can amend our camera on a tripod position and know that we are consistently good view of the foot which we need for our analysis. You will notice that the camera is set directly behind the subject and in accordance with the right foot. For this analysis we focus only on the right foot, and therefore made sure that we are as straight as possible in view of the right leg when he was on the tape (whether it is through how we are measuring the oscillation pronation of the foot in position). Another important factor is speed. We can only really compare the pronation angle between the two videos, if we ensure that the subject is running at the same speed in both videos. With a tape that is how we determine the running speed. In this case, the subject is running at 6 miles per hour in each study. Let’s look at the details of these videos, for some pictures and the comparison of pronation angle in each of the three events. You could do a better job of educating pronation angle by comparing the changing function of time in position (feet on the ground to do) phase, but we want a simple analysis for the present and the best way is to collect 2 common time points. That’s why we are the angle of pronation in the foot strike first and midstance compared (after half of the feet) above the stage floor. To make a proper comparison of the different dates or events, it is always best to digitize points. Scanning is done through the identification of anatomical points on the subject, as the bottom of the heel or the tip of the Achilles tendon. There are several expensive systems that use reflective markers to identify automatically. For our comparison, we have a relatively inexpensive software called MaxTRAQ 2D, developed by our friends Innovision Systems, Inc. and manually scanned the points necessary to rearfoot pronation angle to be calculated. The runner goes barefoot shows no difference in the angle between the strike and pronation of the foot, the average position. 178th angles are measured from 6 to 178 7 degrees. A measure of 180 degrees to suggest that pronation or supination of the foot does not have, so 178th 6 1. Sample 4 degrees of supination (the opposite of pronation), which can be ignored. An angle greater than 180 degrees showing pronation. Then we ask our riders in their shoes, and once again measure the angle of pronation in the celebration of two events. We can immediately see that what our riders supination a little more on your attitude if it is running wearing shoes than when barefoot. At the foot of the angle of attack pronantion 166th 1 or 13 degrees. 9 degrees supination. In midfield has his foot in a nearly neutral position shows only Vienna 4 1 degrees of supination. Our brokers would be neutral, both in shoes and barefoot. Our running shoes are neutral, ie they do not provide support for the pro-or supination. View supination of about 14 degrees in the heel is relatively small and can not see who can down the corridor of the shoe heel, do not understand the position of the feet correctly and may, in another position within the shoe (probably) closer to neutral . If we have correctly calculated the position of the heel, and is more supination when walking in shoes, boots on the topic seems a high degree of damping, which allows convenient in a country where something unnatural position. Walking barefoot can be painful and therefore controls the runner up in the muscles and ligaments around the foot. This way you can avoid pain and injury during delivery. There are no great differences in our experiments, however, and our runners did not run too much pronation or supination during stance phase. Not everyone Bikel Abebe (1960 Olympic marathon winner walked barefoot), and we believe the shoe is more than likely prevented many more injuries he has caused. After buying now know how to analyze the rearfoot pronation, the next pair of running shoes with confidence and understanding.

You should look well-cushioned shoes that some of the blows, and should avoid absorbing shoe stability. Use the heel and the front: Greater wear on the heel and the ball at his feet up on the big toe. New Shoe Tip: Runners who put their feet too far inward, as they show the country, especially in this wear pattern. They often have flat arches and a more flexible foot, so that continues to turn into the floor. Too much rotation in the hip or knee, can also cause. Running shoes offer a variety of arch support, you can limit the active and brokers to maintain their pace in harmony. As plants are broken faster than other runners, with the addition on the floor, these runners must wear rubber soled shoes durable heavy. Use the heel: Heel spent midsole with minimal wear to the ball of the foot. New Shoe Tip: This pattern occurs with runners who have overstride, which means that run with their feet too far in front of his body. Most of the mouth of a overstrider rotation occurs in the air, bringing the heel of the unique position to absorb the force of the collision. Seek Overstriders running shoes that offer little protection because they are more durable and extra cushioning to take some of the shock of landing.

If you can not tell if you have a framework for over-pronator see, or wear their shoes on course to execute someone with you at the bottom of his feet. Ask them to run behind you, they say how he pays his feet on the ground. You have, what type of pronator know before you start looking for new tiles. After you, what type of pronator identified in the right direction for finding the right shoe. If your shoes are used uniformly over the plants, you’re a neutral pronator and need a well balanced, flexible shoes. A well-cushioned shoe is necessary for under-pronator, while a very stable shoe needed to moderate the excessive pronator. Motion control shoes are needed if you have a large excess of pronator are (hopefully not!).

Running shoes when I decided to start taking my running sessions more seriously after a natural question, in my opinion, what kind of ecquipment Shoud I get 3 years? It seemed a difficult task for a beginner: shirts, shorts and a pair of running shoes. Stop. The decision on which type of shoes can be a real pain, believe me. . After some basic research on the Web, sports stores, and my brother used to be a professional athlete in the 10. 000 meters and 5 000 meters away, I concluded that if there was money I needed anything here to make sure it was not the sneakers to be saved! Saving a few euros later (injuries, medical expenses, or worse might be: the surrender to a healthy habit that I have tried to restore). After a few weeks I found exactly what I needed, and bought the Asics Nimbus 10, which is perfectly adapted to high arched feet. . But how do I get up with that? Allows quick tour dummy on the process of selecting the right running shoes. Make your wet test! To make a long story short, three feet at the base, each of them to match our weapons, but all kinds, to reduce the impact on the foot while running. There are several options for you, the foot type that is close, you can not, however, Rocket Science, and keep the wet simple but effective test: 1: Pour a thin layer of water in a shallow pan 2 : step lightly wet the 3rd one: the passage of a bag or a sheet of thick paper 4: Download and view the result of the interpretation of results 1) Flat arch when its surface is visible it means to you have a flat foot – probably overpronator. For this type of foot, there are some good running shoes that might also to the structure of the foot, here are some examples) (only for men’s shoes: Asics GT-2140 RM-729-New Balance Salomon XT Wings Mizuno Wave Nirvana Nike Air 5-Equalon 2 2) Normal Arch This is probably the most common foot type (normal pronator) and that occurred when about half of its arc in the wet footprint test. This short list is a good start for you (just for men ’s shoes): New Balance MR-749-Puma Nike Zoom III Complete magnetizer Equalon 3-Mizuno Wave Renegade 4-Asics Gel-Evolution 5 3) High Arch describes his mark a high arch, and only the toe, heel and a thin line tour traveling outside of your foot (this is really my type of foot): In this case, you might want you to look at this model (for the shoes men) Asics Gel-Nimbus 10-ADIZERO Adidas Boston Running Mizuno Wave Precision 10-Nike Air Pegasus 25 Saucony Progrid Ride My conclusion, the choice of a shoe can be a difficult task, but believe me, it’s worth the trouble to be free from injury due to foot problems and thus be able to develop your career slowly. This is a great sport and even easier in my opinion, the basic training for all athletes in every sport from soccer to rugby, motor racing, tennis, swimming, etc., includes a well-functioning system of any kind, started to end just 2 km without a rest, my weekly routine now consists of 30 km, is only a matter of being persistent, the result, believe me, is great. I hope you enjoy it, Cheers, David
