Running and the association with anthropometric and training characteristics Running can be exercised as a sprint discipline on the train over a few meters to 10 km to Marathon and Ultramarathons over hundreds to thousands of running kilometers.The performance is influenced by a variety of factors of body construction as well as training. Morphological features such as skin folding thickness, body fat percentage, sizes and length of limbs, weight, size and body mass index (BMI) seem to have an impact on mileage. The training circumference (in time and returned distance) and the speed that runs in training also correlate with the performance.If all variables were comparatively examined, so were usually body fat and running speed in training the most important influencing sizes. For longer running loads (over 6 hours resp. 100 km), however, showed that the aspects of experience (number of successfully completed races) and personal best time were far more important than the training scope or morphological characteristics such as the body fat content.
It also became apparent that Ultralaufen are different (deeper speed and higher running volume) preparing as a runner over shorter routes such as half marathon and marathon. The whole work can be found under https://pubmed.ncbi.nlm.nih.gov/26098073/
