Background: Core-strength is vital for Greco-Roman wrestling, although studies have yet to establish the effectives of core-specific training in this sport.
Objective: To examine the effect of core-specific strength training on determinants of Greco-Roman wrestling performance in elite junior athletes.
Methods: Twenty state-level, junior, Greco-Roman wrestlers were randomized into a core-specific training group (COR; n= 12) and a control group (CON; n= 8). The COR group undertook a 4-week, core-specific training program concurrently with their typical training program, whilst the CON group completed 4 weeks of typical training only. Both groups completed overhead medicine ball throw (OMBT), Suplexes, bridges and medicine ball chest throw (MBCT) prior to and following the intervention.
Results: The COR group demonstrated significantly greater improvement in bridges (p= 0.037; F= 5.046) and OMBT (p< 0.001; F= 26.43) than the CON group, with moderate to large between-group effect sizes (ES = 0.79-2.35). In addition, the effect size calculations were moderate-to-large (0.79-0.87) for Suplex and MBCT, with measures for the COR group greater than the CON group.
Conclusion: Accordingly, core-specific training programs should be combined with wrestling-specific conditioning programs to improve back and hip extensor performance in junior Greco-Roman wrestlers.

Metal-Core-Specific Screening with Machine Learning: Accelerating the Discovery of Metal Oxide Clusters for Enhanced EUV Lithography Resolution.

Obtaining effective extreme ultraviolet lithography (EUVL) materials for pragmatic applications remains challenging. The experimental design and conventional theoretical prediction are time-consuming and costly and hardly affordable to accelerate the discovery of commercial EUVL materials. In this work, we employed the machine learning (ML) technique to predict the ionization potential of promising EUVL materials, which is closely related to the photoresists' solubility switch.

In this study, a novel functionalized magnetic composite (MNCGC) for magnetic solid-phase extraction of bisphenols from environmental and food samples was developed, featuring a multistep synthesis with FeO, chitosan, graphene oxide, and β-cyclodextrin, crosslinked by glutaraldehyde. Characterization confirmed its advantageous morphology, intact crystal structure of the magnetic core, specific surface area, and magnetization, enabling efficient adsorption and separation via an external magnetic field. The optimized MSPE-HPLC-FLD method demonstrated excellent sensitivity, linearity, and recovery rates exceeding 80% for bisphenol pollutants, validating the method's effectiveness in enriching and detecting trace levels of bisphenols in complex matrices.

Article Synopsis
- Recent studies indicate that whole-body electromyostimulation (WB-EMS) is an effective and time-efficient treatment for chronic lower back pain (CLBP).
- A non-randomized controlled study involved 40 patients divided into two groups: one receiving only WB-EMS and the other receiving WB-EMS along with passive stretching (Well Back System).
- Results showed that both treatments improved pain and disability scores, but the combination of WB-EMS and stretching led to significantly greater improvements in pain levels, disability, and flexibility.

Implementing an effective software solution is an important step in managing a portfolio of core facilities. Though commercial options are available, developing or adopting a custom platform is a viable path for many institutions. At Northwestern University (NU), the cores program was reorganized beginning in 2008, and we pursued the latter path in order to retain control of the development priorities and to ensure integration with other enterprise systems.

Intervention in the form of core-specific stability exercises is evident to improve trunk stability. The purpose was to assess the effect of an additional 6 weeks sensorimotor or resistance training on maximum isokinetic trunk strength and response to sudden dynamic trunk loading (STL) in highly trained adolescent athletes. The study was conducted as a single-blind, 3-armed randomized controlled trial.
