Objectives: To provide normative values for between-limb asymmetry of hip strength and range of motion (ROM) in professional male soccer players and evaluate the relationship between these asymmetries and groin injury.
Design: Secondary analysis of a prospective cohort study.
Methods: A total of 438 professional male soccer players underwent musculoskeletal screening, injury and exposure surveillance over two consecutive seasons.
Article Synopsis
- * Maximal eccentric and isometric hip adductor torque were measured, revealing no significant differences in torque levels between the two groups throughout the training period.
- * However, the CA group reported higher levels of delayed onset muscle soreness (DOMS) and perceived exertion during certain sessions, particularly between the third and sixteenth exercise sessions, indicating a different experience of exertion between the training methods.
Article Synopsis
- This study analyzed potential head injury situations in 64 matches of the FIFA World Cup Qatar 2022™, focusing on incidents involving players who stayed down for over 5 seconds or requested medical help after head impacts.
- A total of 149 potential head injury situations were identified, averaging 2.33 incidents per match, mostly occurring during aerial duels.
- Results showed that players were more likely to need medical attention for head injuries in specific circumstances, including when jumping or during head-to-head contacts, with 23% receiving on-pitch medical assessments.
Article Synopsis
- The study aimed to analyze and categorize the circumstances surrounding sudden-onset hamstring injuries in professional football players using video footage from matches.
- Researchers reviewed injuries from the Qatar Stars League, focusing on players aged 18 and older, and found that running was the most significant factor, accounting for 86% of the injuries.
- Results revealed that injuries frequently occurred during short sprints (0-10 m) and were often linked to player contact and balance issues, emphasizing the role of pressing actions in a significant percentage of cases.
Objectives: To compare the incidence of headers, attempted headers, and other head impacts, and the difference in heading descriptors, including technical performance, between men and women in a purposive sample of FIFA World Cup 2022 (FWC22) and FIFA Women's World Cup (FWWC23) matches.
Methods: Video analysis of all observed headers, attempted headers and other head impacts during eight FWC matches (FWC22 (n=4); FWWC23 (n=4)) where the same national teams competed. Heading descriptors (including ball delivery method, purpose of the header and involvement of other players) and technical performance of each header (including controlled or uncontrolled header, use of upper body, point of head contact) were analysed using negative binomial regression analyses with men as the reference group (reported as incidence rate ratios (IRR)).
