Assessment and development of human strength and power 

### Welcome to the fourth Cultural Evolution Society Conference, CES2022! 

As last year, Underline will support the online component of the conference. The ongoing COVID-19 pandemic is causing a great deal of uncertainty for all of us. Therefore, we seek to offer a hybrid format that will hopefully allow some folks to travel to Aarhus, others to meet up locally or regionally in CES hub-lets, and other yet to participate online. The field of cultural evolution is growing in size and scope; its theories, methods and applications - both academic and applied - are getting ever more robust. Do join us in what promises to be an exciting exchange of ideas and a celebration of our field.

Most human activities, including sports, are becoming more and more technological. Engineering in general and Information Technology in particular are important in the support for many activities directly or indirectly related to sport sciences, including improvement of physical activities, sports medicine, biotechnology and nutrition, sports management, and all other application areas in sports. This conference intends to be a meeting point for both academics, sport professionals and practitioners to exchange ideas and develop synergies. .

In this lecture, I will present what we know so far about the biomechanics or hydrodynamics of front crawl, focusing on propulsive and resistive forces at different speeds. Recent studies show that the resistive force increases in proportion to the cube of the velocity, which implies that a proficient technique to miminise the resistive (and maximise the propulsive) force is particularly important in sprinters. To increase the velocity in races, swimmers increase their stroke frequency. However, experimental and simulation studies have revealed that there is a maximum frequency beyond which swimmers cannot further increase swimming velocity due to a change in the angle of attack of the hand that reduces its propulsive force. While the results of experimental and simulation studies are consistent regarding the effect of the arm actions on propulsion, the findings of investigations into the effect of the kicking motion are conflicting. Some studies have indicated a positive effect of kicking on propulsion at high swimming velocities while the others have yielded the opposite result. Therefore, in this lecture, I would like to integrate the results of previous studies and explain how swimmers control their swimming speed from various perspectives.

How do Swimmers Control their Front Crawl Swimming Velocity?

Resistance training is well known to induce adaptive changes in the morphology and architecture of human skeletal muscle, while also leading to adaptive changes in nervous system function (Aagaard 2003, Aagaard et al. 2020). These changes contribute to the marked increase in maximal contractile muscle force and power that can be seen with resistance (strength) training not only in athletes but also in previously untrained persons, including frail and very old (>80 yrs) adults and patients.Importantly,the training induced improvements in skeletal muscle size/architecture and neuromuscular function are translated into improved athletic performance in younger adults, while correspondingly leading to an enhanced functional capacity during activities of daily living in aging individuals and patients, respectively.
