Our bones are quite remarkable in that they are capable of going through a process known as remodeling. What this means essentially is that our bones can change shape. We have little cells called osteoclasts and osteoblasts that can break down old and build up new Nike Air Vapormax Womens bone (respectively), and they do a very good job of it. When we stress a particular spot on a bone repeatedly, it can begin www.aquarillon.fr to develop micro damage – think of micro damage as tiny cracks that weaken a bone in that spot. The remodeling process repairs that damage, and ultimately will make the bone stronger and better able to withstand that stress. The catch is that it has to be allowed to happen. Remodeling takes time, and the damaged spot can actually get a bit weaker (as damaged bone is removed) before it is repaired and becomes stronger. If we repeatedly stress a bone in the same way over and over without giving it a chance to rest and repair, micro damage accumulates and can lead to a stress fracture. If we continue to stress a bone that has already developed a stress fracture, you can imagine what will happen next – snap!This Nike Air Max 270 Damen same type of process applies to many soft tissue injuries as well, and muscles are a good example. When you go lift Nike Air Max 90 Mens weights for the first time in a long time you get incredibly sore for the next few days (this is called delayed onset muscle soreness or DOMS). What has happened is that you have damaged your muscles on a microscopic level, and as they repair themselves they become stronger and larger. This is the fundamental process by which we are able to increase strength through resistance training. However, if you decide to start working out and you do the same routine every day for a week or two, you’re asking for trouble. We could apply this same logic to an extent to ligaments and tendons as well. The body is amazingly good at adapting, we just need to allow it to do so.Repetitive overuse injuries are perhaps the most common www.jamlikhalsavast.se type of injury experienced by distance runners (including things like plantar fasciitis, Achilles tendonitis, shin Nike Air VaporMax Mens splints, stress fractures, etc.). Thus, in the context of what I have discussed above, it’s critical to address the question of Nike Air Max 90 Womens Pink why these overuse injuries happen. The answer to this is pretty much summed up by the quote I chose to open this post. Repetitive use injuries occur when repeated stresses are placed upon a structure, none of which individually causes acute damage, but the sum of which leads to a progressive degeneration of that structure. In simple terms, if you pound on a bone too frequently without rest, it’s eventually going to break. If you overstretch a ligament repeatedly, it’s eventually going to get sore and possibly tear. I think you get the picture. A helpful way to think of this is demonstrated by Nike Air Max 270 Femme the graph below, adapted from Hreljac (2004).The above graph looks at training and injury likelihood as a balance Adidas Campus Femme of intensity and frequency. High intensity workouts (e.g., hard speedwork, long runs) are more taxing on the body, thus if Adidas Superstar Femme they are done frequently your training will exceed the injury threshold (the curved black line) and you’re asking for a problem. However, if your workout is low intensity (e.g., a short recovery run at a slow pace), you can do that workout frequently and not likely get hurt (i.e., you will remain in the “no injury” region).The thing to keep in mind in the above graph is that the exact shape and height of the curve will likely vary from person to person (some people are simply more injury prone than others, some can tolerate hard workouts better than others), from time to time within a single individual (e.g., with degree of overall fatigue), on different running surfaces (dirt vs. asphalt vs. concrete), and Nike Air Max 90 Femme Rose even in different pairs of shoes. As an example of the latter, when a person used to wearing cushioned, heel lifted shoes Adidas Superstar Homme goes for their first run in a pair of Vibram Fivefingers (see picture above), which lack a heel lift and are minimally cushioned, the entire injury threshold curve probably shifts downward (see green line in graph below). Thus, in beginning Vibram runners, even low intensity runs should not be done frequently at the start, and high intensity runs can cause problems immediately (i.e., you don’t want your first Vibram run to be an all out 5K race).
