Objectives: The purpose of this study was to establish beliefs and practices of physical performance coaches regarding sprinting and Hamstring Strain Injury (HSI) in Australian Rules football.
Designs: Delphi-validated questionnaire.
Setting: Online.
Participants: Eighteen high-performance managers of the Australian Football League.
Main Outcome Measures: Descriptive statistics were collected to establish experience; central themes were established for the analyses of the beliefs and practices.
Results: Nine (50%) physical performance coaches responded to an invitation to complete the questionnaire. Participants held an undergraduate degree and had 9.2 ± 4.3 years of experience. Accelerations (n = 9), maximum speed sprints (n = 9) and running with hip flexion (n = 7) were the most common activities associated with HSI. Coaches believed sprinting, eccentric strength training and proper periodisation were effective strategies to reduce HSI risk. There's a disparity between beliefs and practices when using GPS to monitor sprinting, however, all coaches reported regular exposure to sprint training across both pre and in-season. Overstriding (n = 9) and pelvic instability (n = 6) were identified as key flaws in running mechanics.
Conclusions: This information can be used to improve training strategies, whilst these findings indicate further investigations into sprint training and running mechanics for HSI risk reduction.

Under Japanese rule in 1912, cremation was legalized in Korea, marking a shift from a strictly prohibited practice to an accepted funeral option. Initially viewed as a Japanese custom, cremation gradually transformed into a "civilized" choice, a perspective pushed by Japanese colonial authorities and some Korean modernizers. However, this narrative overlooks the gradual acceptance of cremation among Koreans.

Surprisingly innovation process based on deliberate practice has rarely been unearthed that might explore the boundary conditions of the eco-friendly deliberate practice and eco-innovation performance relationship. Anchored on the organizational support theory and the social cognitive, the current study seeks to investigate the impacts of perceived organizational support (POS) and developmental leadership (DL) on eco-innovation performance (EP) through the mediating role of eco-friendly deliberate practice (EDP). In addition, the study explores the boundary effects of employee resilience (ER) on the relationship between EDP and EP.

This study explores the integration of sexual and reproductive health (SRH) education in Sri Lanka, utilizing the Health Belief Model (HBM) to predict the perceived quality of SRH education among non-state undergraduate students. In many Asian countries, including Sri Lanka, cultural resistance and skepticism often challenge SRH education initiatives. The research is based on a questionnaire survey, examining factors influencing the perceived quality of SRH education, such as cultural norms, embarrassment, attitudes, awareness, and institutional support.

However, this approach has its own challenges, including reports that its focus on communication and relationships is undervalued despite evidence supporting its use to facilitate practice improvements in hospitals. Research suggests power dynamics in hospitals influences how the RMOC is used, but the precise mechanisms through which this occurs have not been fully examined.

Design/methodology/approach: This paper conducted a cross-sectional in-person survey with 38 leaders and 224 PCPs in 38 primary health centers (PHCs) in Jinan, Tianjin, Shenzhen and Shanghai. Guided by the regulatory focus theory, this paper built hierarchical linear regression models to examine the association between the leadership's regulatory focus and physician burnout, work-family conflict, clinic guideline adherence and preventive service delivery.
