Background/Objectives: To address the inconsistent provision of specialist physical education (PE) in primary schools, this study investigated the comparative efficacy of distinct team-teaching configurations. The objective was to compare these instructional models' impact on students' basic motor competencies (MC) and self-reported physical literacy (PL). Methods: This quasi-experimental, cluster-randomized study involved N=266 students (grades 1-4) assigned to one of five instructional models: single PE teacher or four team-teaching configurations (Generalist Teacher + PE Teacher [GT+PE T], Generalist Teacher + Assistant Teacher [GT+AT], Generalist Teacher + Sports Coach [GT+C], and PE Teacher + Assistant Teacher [PE T+AT]). The five-month intervention included two 45-minute PE lessons weekly. Motor competence (MC, MOBAK) and perceived physical literacy (PL, PLAYSelf) were assessed pre- and post-intervention. Given the cluster design and non-normal data, non-parametric tests were used; Kruskal-Wallis H-test compared change scores between groups, complemented by Spearman’s rank-order correlations for construct alignment and covariate analysis. Results: Statistically significant within-group overall MC gains were achieved exclusively by configurations including a qualified PE teacher (GT+PE T and PE T+AT; p < 0.05). The GT+PE T model showed the largest positive change, including significant PL improvement (Δ = +5.65). Conversely, the GT+C model resulted in a significant decline in self-reported PL (Δ = -9.16). A small but significant positive correlation (ρ = 0.149) emerged between Object-Movement skills and Perceived Physical Literacy post-intervention. Conclusions: The effectiveness of collaborative PE instruction is highly dependent on the explicit inclusion of a qualified PE teacher, reinforcing the crucial role of specialized pedagogical content knowledge. Models lacking this core expertise may be detrimental to both motor skill development and the affective components of physical literacy. These findings highlight the need for policy focused on high-quality, PE teacher-led primary PE.

In recent years, much effort has been made to reduce the injury rate in combat sports. However, the question remains to what extent these measures are effective. Analysis of studies could provide evidence of the effectiveness of measures aimed at reducing the incidence of injuries. This scoping review aims (1) to map research articles dealing with the effectiveness of proper use of protective measures in reducing the incidence of injuries in combat sports; (2) to investigate to what extent the proper use of protective measures and compliance with sports rules help to reduce the incidence of injuries in combat sports; and (3) to identify gaps in the existing literature and suggest future research on this topic. The literature search was conducted on articles published between 2010 and 2023. The main inclusion criteria were studies investigating the effect of sports rules and protective equipment used during training or competition in combat sports on reducing the incidence of injuries. After meeting the criteria, only seven articles from boxing, karate, and taekwondo were included in this study. Results showed that mandatory head guards, along with modern thicker gloves, significantly reduced the rate of knockouts (KOs) and head injuries in boxing despite an increase in the number of head blows. However, the number of facial cuts increased significantly due to the removal of head guards as a piece of mandatory equipment. The use of mouth guards has significantly reduced the number of oral injuries. Changes in rules, such as shortening the duration of bouts, along with the introduction of greater competencies of referees in the supervision of bouts (the standing count, outclassed rule, and medical stops) have helped to reduce the rate of injuries in boxing. The application of a computerised scoring system also contributed to the rate of injuries reduction. The increase in the number of weight divisions had the same effect on U21 karate athletes. However, a higher incentive to attack the head area in taekwondo did not increase the incidence of injuries in youth athletes. It can be concluded that the proper use of protective measures (head and mouth guards) in combination with the rules established for health protection (higher competencies of referees and more weight divisions in competitions) effectively reduces the occurrence of injuries in combat sports. In all Olympic combat sports, the injury incidence should be regularly assessed using the Injury Incidence Rate (IIR) per 1000 min exposures (MEs). Nonetheless, further studies are needed to monitor how established rules (e.g., prohibited behaviour) affect the IIRs.
