Methods : Data were collected from a quantitative online survey of German physical education teachers from primary and secondary schools ( n = 551). T...
Learning to swim promotes lifelong engagement in aquatic physical activity. Such engagement is defined as one of
the six interventions identified by the World Health Organization (WHO, 2017) and is frequently considered to be
prominent among those (Brenner et al., 2006; Stallman et al., 2014; WHO, 2014). The WHO emphasizes the
importance of swimmin...
Introduction
Sport, across various social contexts, exhibits inherent racist structures and incidents, impacting children and youth. Physical Education (PE) has the potential to fight racism, yet simultaneously serves as a setting where racist elements may be (re)generated. Given that teachers are central figures in education with a direct impact o...
Relative age effects (RAE) refer to a skewed distribution with an overrepresentation of athletes born close to the selection date. The prevalence of RAE has been repeatedly demonstrated in youth swimming. Additionally, being more mature within an age group is associated with consistent selection advantages. The present study aims to determine (1) t...
Racist structures and incidents are prevalent in all facets of sport, and these experiences are also encountered by children and youth. Physical Education (PE) has the capacity to be a platform for combating racism, yet it can also be an environment where racism is either perpetuated or revived.

Introduction
Sport in all social forms is characterized by racist structures and incidents, also experienced by children and youth. Physical education (PE) can be an area to fight racism but can also be an environment where racism is (re)produced. The perspective of pupils is crucial in teaching research as they are the primary individuals experien...
Abstract: Defining the "functional equivalence" between motor imagery (MI) and the actual dynamic execution of a motor task is of crucial importance. Achieving this understanding may enable artifact-free neuroscience of sporting behaviour, consequently facilitating big data pattern recognition to decode and predict motor behaviour. To date, however...
Epidemiological reports on physical inactivity (Guthold et al., 2020) and drowning accidents (WHO, 2014) show that the 6-12-year-old population are not protected to take advantage of the aquatic environment as an opportunity to practice in the water environment while they are lifelong activities (Chase et al., 2008). To carry this dual aquatic safe...
The positive effects of combined hyperoxia and physical exercise on physiological parameters and cognitive functioning are established for normobaric laboratory contexts.

The following stages may be processed during learning-to-swim: 1) following a general familiarization to water, 2) five basic aquatic skills (i.e. fully submerge, learn a rhythmic and steady breathing pattern with the added pressure of water, be able to float prone and supine using buoyancy, glide with reduced drag, and dive safely into the water)...
Schools are an excellent setting for health promotion in children and adolescents. In particular the school subject physical education (PE) offers high potential in this regard. The following paper applies the salutogenic model of Aaron Antonovsky to PE in schools. This approach focuses on strengthening the sense of coherence with its central facto...
The tiebreak in tennis is one of the most-contested situations during a set. Often the outcome of a tiebreak is trendsetting for the match. Thus, every point in a tiebreak may be defined as a “big point”, and only the best players are able to play their best tennis. However, differences in players’ performances between tiebreak points (TBP) and non...
Digitalisation more and more impacts todays' everyday life, not least our schools and, thus, pupils.

In view of the latest rule modifications subsequent to the 2016 Olympic Games, this study investigates recent changes in judges' scorings with respect to changes in the ch...
Relatively older athletes, who were born in the first two quartiles of a year, have an increased probability of being selected and exposed to a higher level of coaching, training and other talent-promoting factors. Therefore, it is considered as one of the errors within the process of talent identification (Wattie, Schorer & Baker, 2015). Research...
In gymnastics, mainstream handstand coaching emphasizes developing an aligned rigid body configuration, frequently leaving wrist-controlled balance work to implicit learning. However, skill-related motor behavioral research suggests the wrists to primarily contribute postural control in handstands. Considering recent research on handstands revealin...
Changes in gravity conditions have previously been reported to influence brain hemodynamics as well as neuronal activity. This paper attempts to identify a possible link between changes in brain blood flow and neuronal activity during microgravity. Middle cerebral artery flow velocity (MCAv) was measured using Doppler ultrasound. Brain cortical act...
Previous studies showed a decrease in reaction time during the weightlessness phase of a parabolic flight. This effect was found to be stronger with increasing task complexity and was independent of previous experience of weightlessness as well as anti-nausea medication. Analysis of event related potentials showed a decreased amplitude of the N100-...
Alpha inhibitory processes reflect motor stimuli by either increasing or decreasing amplitude (i.e., power). However, the functional role and interplay of event-related alpha oscillations remains a regulatory domain that has not been sufficiently addressed, particularly with respect to different muscle activation types and durations in consecutive...
Training in a particular sport not only leads to a higher accuracy in movement, it also creates neuronal modulations in different areas of the brain. Electroencephalography (EEG) has been on the rise to detect these neuronal modulations to address applied research approaches in sports-specific setups with focus on movement-related cortical potentia...
Video analysis and feedback, especially through the use of mobile learning devices (MLDs), has established itself as a principal
coaching instrument in the coaching toolkit. It provides an excellent source of information to learners about their movement,
and when used effectively can speed up motor learning. This article provides recommendations on...
Tennis comprises specific match situations when winning the next point is crucial. These big points can decide about a win or loss and, thus, reasonably arouse mental stress. Break points (BPs) are considered as big points and the outcome is influenced by, among a variety of other factors, the serve, which is well accepted being one of the dominant...
INTRODUCTION: It is possible to compete in different swimming strokes at a single competition. The German Swimming Federation sup-ports stroke variety and underlines the importance of individual medley as a prerequisite for becoming an elite-level swimmer while focussing on big training loads at young ages at the same time (Lambertz, 2014). On the...
