The first webinar of the ECSS Special Interest Group (SIG) on Distance Running at ECSS was held in Paris in July 2023. Among the actions discussed during the meeting was the launch of a series of webinars on the topic. In this webinar, we will address a series of myths and popular beliefs in running.
The preferred running style adapted by runners is metabolically optimal for them, i.e. the pattern that allows minimal energy consumption. Despite this, runners still are still sometimes recommended to change their running to a more ‘right’ way to run. This talk will present an overview of evidence on the short and long-term effects of running retraining on improving running economy and on reducing the loading on the targeted and the adjacent joints.
Most running-related injuries develop progressively over time and may be caused by the repetitive loads applied to the musculoskeletal system. If the causal link between impact forces and injury development sounds common sense, the scientific literature has been rather inconsistent over the last decades. This talk will first define the concepts and the aetiological framework before presenting important methodological considerations for the analysis of impact loading and the scientific evidence on the relationship with injury risk.
Running 4 to 10 marathons in a row is crazy and cannot come without health consequences: this is probably what most people think! Beyond the acute effects of running ultra-marathons - that are not necessarily 100 miles and longer – such as neuromuscular fatigue, we will discuss what we know and what we don’t know about the long-term consequences of running ultras. In particular, we will show that (i) there are different ways of practicing ultra-marathon and (ii) the level of performance rather than the distance run in competition determine the training volumes.
Sedentary behavior has short and long-term consequences on cognitive performance and more generally on cardiovascular and metabolic health. The energy expenditure of runners is such that they can be considered very active in a physiological point of view. This characteristic of their lifestyle brings them a large number of benefits in terms of health, but is it enough to protect them against the harmful consequences of a sedentary lifestyle when they spend long periods in a sitting position? This presentation will take stock of the state of our knowledge on this subject.
Progression in training volume over time is considered important for performance enhancement. However, excessive progression in weekly mileage and/or intensity has been linked with running-related injuries. In running populations, the 10% rules serves as a rule of thumb enabling runners to progress their mileage and/or intensity with limited injury risk. The question remains: what exactly is 10% and is there scientific evidence to support it?
