Preservation of Temporal Organisation of Tennis Service Following Ageing in Recreational Players.

Ageing leads to functional changes in body systems. This study sought to examine the age-based differences in temporal patterning, temporal variability and temporal regularity of tennis service in older adults. cross-sectional study.

Towards an ecological dynamics theory of flow in sport.

Flow is an optimal state of absorption that may be experienced in appropriately challenging and intrinsically motivating activities such as sports. Flow may be an important concept for understanding the emergence and role of sport in society, yet theoretical explanations of flow have had limited success explaining, predicting, and facilitating flow in sport. Here, we use the ecological dynamics framework, seeking to resolve foundational issues in an explanation of flow, building towards a theory of flow in sport.

Wearable System Applications in Performance Analysis of RaceRunning Athletes with Disabilities.

RaceRunning is a sport for disabled people and successful performance depends on reducing the amount of time spent travelling a specific distance. Performance analysis in RaceRunning athletes is based on traditional methods such as recording race time, distances travelled and frequency (sets and reps) that are not sufficient for monitoring training loads. The aims of this study were to monitor training loads in typical training sessions and evaluate technical adaptations in RaceRunning performance by acquiring sensor metrics.

Learning to Cycle: Why Is the Balance Bike More Efficient than the Bicycle with Training Wheels? The Lyapunov's Answer.

Background/objectives: Riding a bicycle is a foundational movement skill that can be acquired at an early age. The most common training bicycle has lateral training wheels (BTW). However, the balance bike (BB) has consistently been regarded as more efficient, as children require less time on this bike to successfully transition to a traditional bike (TB).

Beyond the Pitch: Unveiling the Concave Hull as Soccer's Ecological Niche in Practice Design.

An ecological niche is a field in a landscape of affordances, rich in information inviting its inhabitants to develop functionality and effectiveness of their behavior. This idea means that, in sports like soccer, the playing area encapsulates an ecological niche, replete with affordances inviting collective and individual technical-tactical actions, contextualized with associated psychological and physical demands. To examine the co-adaptive relationships framing players' actions in their ecological niche, the present study employed a crossover design with repeated measures to compare the players' transactions within 11 vs.
