Data-driven match analysis in soccer is a growing discipline in both research and practice. However, public data is scarce, which raises the barrier for entering this field and decreases reproducibility of methods and results. To bridge this gap, this paper presents a dataset of official match information, event, and position data from seven matches of the German Bundesliga’s first and second division. The match information contains meta data about the matches and their participants. The event data contain timestamps along with descriptions of discrete events, like passes, shots, or fouls. The position data contain the x/y-coordinates of every player and the ball. By integrating multiple data modalities – i.e., event logs with timestamps, and x-y coordinates of player and ball positions — the dataset offers a multidimensional view of match dynamics. This dataset supports the validation of existing analytical techniques and facilitates the development of new methodologies in sports analytics. With availability under CC-BY 4.0, it promotes transparency, reproducibility, and the idea of open science in match analysis research.

Triterpenoids, known for their anti-inflammatory, anticancer, and hypoglycemic properties, are the major bioactive components in Cyclocarya paliurus (Batal.) Iljinskaja. Selecting elite individuals with high triterpenoids content is the basis of C. paliurus industry for medicinal use. In this study, seasonal variation patterns of total triterpenoids and five triterpene monomers accumulation for three groups with different total triterpenoid contents (TTC; H: 59.74-64.03 mg g-1; M: 47.66-57.08 mg g-1, and L: 35.26-42.22 mg g-1) were surveyed. Seasonal expression dynamics of 6 key genes relevant to triterpenoids biosynthesis, including HMGR, DXR, SQS, SE, LUS, and β-AS, were described by quantitative real-time PCR (qRT-PCR) for three groups. The expression levels of HMGR, SE, LUS, and β-AS genes in group H were higher than in groups M and L. In addition, Pearson correlation analysis showed that they were significantly positively correlated with triterpene accumulation, and the expression level of SE gene not only was significantly correlated with downstream genes, but also exhibited a linear relationship with TTC, especially in September. These results suggest that SE gene could serve as an effective make for screening elite individuals with high TTC from the germplasm of C. paliurus for medicinal use. Further testing on randomly selected individuals in next September proved the feasibility and reliability of SE gene in assisted selection. Also, we successfully cloned the full-length cDNA of SE. Thus, our work provides an efficient way to attain superior genotypes to develop medicinal industry of C. paliurus in practice.

Introduction Vision serves as a critical channel for athletes to acquire information during competitions and constitutes a vital component of their competitive ability. Through scientifically designed sports visual training, specific visual skills can be enhanced, thereby assisting athletes in achieving optimal performance in competitive settings. This study aim to explore the visuomotor abilities and shooting performance of skeet shooters through Sports Vision Training (SVT). Methods Twenty elite skeet shooters were recruited and randomly assigned to an experimental group (EXP, n = 10) and a control group (CON, n = 10). The EXP underwent 6-week of SVT on Senaptec Seneory Station, twice a week, while the CON completed an equivalent workload of target-tracking training. Result Visuomotor skills testing showed significant improvements in Near- Far Quickness, Perception Span, and Eye-hand Coordination in the EXP (p < 0.05), with no changes in the CON. Comparative post-test results between the two groups showed significant differences in N/F Q, Target Capture, Perception Span, Eye-hand Coordination, and Go/ No Go (p < 0.05). In shooting performance indicators, EXP shooters showed a highly significant improvement in hit accuracy (p < 0.01), with a similar difference compared to the CON. Additionally, they exhibited a highly significant improvement in shotgun-mounting reaction time (p < 0.01). Kinematic indicators of shotgun movement during the firing process for shot 2 showed significant differences in peak velocity (p < 0.01), X-axis (p = 0.033) and Y-axis (p = 0.001) displacement. Conclusion SVT can enhance visuomotor abilities in skeet shooters and has a positive impact on their shooting technique. This is primarily manifested in shorter shotgun-mounting reaction time and improved efficiency in action at shot 2, effectively improving their shooting accuracy.

Abstract Ribeiro, N, Martinho, DV, Pereira, JR, Rebelo, A, Monasterio, X, Gonzalo-Skok, O, Valente-dos-Santos, J, and Tavares, F. Injury risk in elite young male soccer players: a review on the impact of growth, maturation, and workload. J Strength Cond Res 38(10): 1834–1848, 2024—The long-term development of young male soccer players involves a prolonged period of significant adjustments, highlighting the importance of studying the complex interaction between dynamic variables, including workload, and inherent elements like growth and maturity. This analysis examines the intricate connections involving the development, maturity, workload, and susceptibility to injuries among adolescent male soccer players. Significantly, these connections become prominent at the peak height velocity (PHV) period, a crucial moment in maturation. Growth rates vary among individuals, and higher rates have been associated with an increased risk of injury in young soccer players, particularly during periods of rapid growth. Identifying possible risk factors and understanding the complex connections between them is crucial to developing specific methods for reducing the risk of injury. Sharing this valuable information with essential stakeholders is crucial for guaranteeing young athletes' comprehensive growth and maturation process. Furthermore, this review emphasizes the immediate need for long-term studies and thorough injury analyses to comprehend better the dynamic interactions that influence injury patterns in young male soccer players. This review will allow practitioners to better understand the main modifiable and nonmodifiable risk factors for injury and provide essential information focusing on practical strategies, facilitating more informed decision making by all stakeholders. The review aims to clarify these complexities and offer crucial insights that can assist in designing and implementing efficient strategies to reduce the risk of injury, specifically for the challenges faced during PHV and within the broader framework of long-term athletic development in young soccer.

Implementing a collaborative pre-breeding multi-parental population efficiently identifies promising donor x elite pairs to enrich the flint maize elite germplasm. Genetic diversity is crucial for maintaining genetic gains and ensuring breeding programs’ long-term success. In a closed breeding program, selection inevitably leads to a loss of genetic diversity. While managing diversity can delay this loss, introducing external sources of diversity is necessary to bring back favorable genetic variation. Genetic resources exhibit greater diversity than elite materials, but their lower performance levels hinder their use. This is the case for European flint maize, for which elite germplasm has incorporated only a limited portion of the diversity available in landraces. To enrich the diversity of this elite genetic pool, we established an original cooperative maize bridging population that involves crosses between private elite materials and diversity donors to create improved genotypes that will facilitate the incorporation of original favorable variations. Twenty donor × elite BC1S2 families were created and phenotyped for hybrid value for yield related traits. Crosses showed contrasted means and variances and therefore contrasted potential in terms of selection as measured by their usefulness criterion (UC). Average expected mean performance gain over the initial elite material was 5%. The most promising donor for each elite line was identified. Results also suggest that one more generation, i.e., 3 in total, of crossing to the elite is required to fully exploit the potential of a donor. Altogether, our results support the usefulness of incorporating genetic resources into elite flint maize. They call for further effort to create fixed diversity donors and identify those most suitable for each elite program.
