In Ultimate Frisbee, players are responsible for administering and reinforcing adherence to the rules of the game. As a self-refereed sport, UF relies upon the Spirit of the Game (SOTG). This study aimed to profile the experience, to ascertain the training history of the sport, the participation and goal orientations of international Ultimate Frisbee players in the European Beach Ultimate Championship, and to evaluate the contribution of these variables in a discriminant function to classify players according to SOTG level and competitive level. The sample consisted of 160 players [females 33.8% (29.3 ± 7.2 years); males 66.2% (37.6 ± 9.7 years)] who competed in the European Beach Ultimate Championship, 2019. Factorial ANOVA was used to test the effect of sex, competitive level and SOTG level (measured by the sum of the scores obtained in five questions addressing the following domains: (1) Knowledge and use of the rules; (2) Fouls and body contact; (3) Fair-mindedness; (4) Positive attitude and self-control; (5) Communication. The results revealed that sex was not a consistent source of SOTG level variation among players. In each competitive level, those with high SOTG levels obtained lower European Beach Ultimate Championship classification (t = 5.73 to 6.55, p < 0.001, d = 1.28 to 2.06), higher SOTG classification (t = −13.21 to −7.04, p < 0.001, d = 1.28 to 2.85), and better evaluation for fouls and body contact (t = 2.76 to 9.23, p < 0.05, d = 0.86 to 1.99) and for positive attitude (t = 5.88 to 7.43, p < 0.001, d = 2.06 to 2.57), than regular SOTG level players. Players of different competitive levels demonstrated similar SOTG results. These findings provide important information to coaches, physical education teachers and sport consultants.

Background: Nutrition underpins athletic performance, enhancing training, reducing injury risk, and accelerating recovery. In the event of an injury, performance dietitians (PDs) and nutritionists' (PNs) play a vital role by tailoring nutritional strategies to support tissue repair, optimize athlete's recoveries, and return to play.
Objectives: This study explored nutritional strategies recommended and employed by Irish PDs and PNs to assess, manage, and support athletes during the initial stages of sports-related injuries.

The supramolecular organization of functional molecules at the mesoscopic level influences their material properties. Typically, planar π-conjugated (disc- or linear-shaped) molecules tend to undergo one-dimensional (1D) stacking, whereas two-dimensional (2D) organization from such building blocks is seldom observed in spite of their technological potential. Herein, we rationally achieve both 1D and 2D organizations from a single planar, π-conjugated molecular system competitive interactions.

Objectives: Sport-related concussions are a global health concern. Athletes consistently underreport sport-related concussions, and knowledge and attitudes about sport-related concussions vary between levels of sport competition and according to a range of factors. It is unclear how concussion knowledge and attitudes relate to reporting behaviours amongst community sport athletes.

As one of the major sources of greenhouse gas (GHG) emissions, the municipal solid waste (MSW) management system was regarded as a key contributor to the construction of a low-carbon society. Understanding the evolution of waste treatment facilities and the corresponding GHG emissions was essential for assessing the low-carbon competitiveness of local communities. In this study, facility-level data were used to estimate GHG emissions from the waste management system in the Yangtze River Delta (YRD) and analyze their temporal and spatial variations.

Recruitment of progeny to coral reef populations involves complex ecological interactions, influenced by environmental factors such as altered underwater light conditions associated with poor water quality. Here, we exposed newly settled corals (Acropora millepora and Acropora cf. tenuis), the sponge (Phyllospongia foliascens), and their substrate communities to various light intensities and spectral profiles relevant to turbid inshore reefs.
