There is no one right running technique
If you have ever watched a professional run, e.g. at the Berlin Marathon or running competitions within the framework of championships, you will have discovered many different running styles. Therefore, first of all: There is no such thing as THE right running technique. Rather, training is about finding the right style for your physique and ambitions. If your main goal is to become faster, running efficiency and economy play a central role.
On the one hand, this means that the actions of your muscles are better coordinated and you lose less energy through possible compensatory movements. A perfect running style is therefore characterised by the harmonious interaction of your muscles.
On the other hand, efficiency in running style means that the oxygen consumption during running remains as low as possible. The less oxygen and energy you need to run at a certain pace, the longer you can maintain that pace.
But there is another reason why it is important to improve your running technique: Injury prevention. Because muscle parts that are not trained in a balanced way can lead to misalignments or deficiencies in movement coordination, which in turn significantly increase the risk of injuries. In addition to increasing efficiency, an improved running style is therefore also important for staying injury-free for as long as possible and being able to pursue your sport to your heart's content.
