Arch-spring or #windlass mechanism? The stiffness of #sprinters’ and #swimmers’ feet: A pilot study. Presented at the Conference of the European College of Sport Science in Paris 2023. Measuring stiffness of the human foot works!

We created a dataset containing competition records from the 2013–14 to 2020–21 seasons (500 m event) on the official website. Methods One-way ANOVA was applied to statistically analyze whether the best performance times exhibited significant differences in varied hosting cities. Performance–time matrix and multivariate regression model were further established to quantitatively explain how geographical factors (longitude, latitude, altitude, and barometric pressure) affected performance. Results Our findings firstly confirmed that the fastest 500 m finishing times varied due to the hosting cities (P = 0.008) and showed that venue locations could boost or impair performance time with the maximum range of 3.6 s. Meanwhile, latitude (slightly over 46° when performance is maximized) was the most influential factor to account for the performance–time difference in different ice rink locations according to the multivariate regression model, though altitude (1,225 meters when performance is maximized) was also important. Conclusions In this perspective, elite skaters should check the geographical factors of the venues before they participated in the upcoming competitions, assess the real strength of their rivals, and adopt flexible tactics during training sessions.

As athletes from all corners of the world gathered for this year’s Olympic Games in Paris, we were reminded of the incredible intersection of sports and mathematics.  From basketball player Stephen Curry’s winning three-point shots to star swimmer Léon Marchand setting new records in four individual events, the athletes we admire pushed the boundaries of human potential, but behind every record-breaking performance lies a foundation of science. Can the depth of a pool determine how fast you will swim? Why shouldn’t you rely on doping tests too much?  Why do golf balls have dimples? In her latest book, "Be a Champion: 40 Facts You Didn't Know About Sports" (Pourquoi est-on penché dans les virages), French mathematician Amandine Aftalion uses a blend of physics and mathematics, and a touch of humor, to answer 40 questions that will help you improve your sports game and better understand the technique of champions.

Practice is the key to perfection!

🏅 Sport ‘performance’ is complex and chaotic phenomenon. Establishing what tests and measurements are valid to the context is not straightforward in most cases. 📝 Our latest paper brought together Sam Robertson, Jade A.Z. Haycraft and David Carey, with backgrounds spanning sport science and applied mathematics to solve this problem. 📊 By considering validity theory and the complexity sciences we developed a framework for test and measurement selection in S&C and sport science, that can be implemented across a range of contexts. The framework contains several features, including: 👉 Layers of validity (i.e., a network of inferences) 👉 Measurement properties 👉 Decision making factors 👉 Organisational factors 🚦 We also provide several case examples of how the framework can be applied. 🔗 Check it out here (Open Access) https://shorturl.at/TfBQw

🚀 𝗡𝗲𝘄 𝗣𝗮𝗽𝗲𝗿 𝗢𝘂𝘁: A framework for test measurement selection in athlete physical preparation. 🏃♀️ Physical test selection is fundamental to the training process when preparing athletes for sport performance. However, choosing the right physical test and metrics is complicated by the myriads of assessment methods available to sports practitioners. 📰 Our latest paper presents an evidenced-based process to inform physical test measurement selection for athlete preparation. The proposed framework incorporates multiple layers of validity to link test measurements to competition performance, and considers the technical, decision-making, and organisational factors that impact physical test suitability. 👇 Discover how this framework can assist in transforming your training strategies by ensuring your physical test measurement selections truly impact athlete performance.

Sports and Design of Experiments (DoE)? Yes, you read that right! My student along with some wonderful global scholars have published a novel application of DoE to optimise the performance level of a national curling sport team. The results obtained from DoE suggest that certain factors have a substantial impact on the score of the player's draw game. The findings of this study can be beneficial to other sports events in improving performance. DoE has proved to be an invaluable tool for many people in the German Curling Association in understanding the factors that influence curlers' performance. Interested in learning more?
