This study aimed to determine the rated perceived exertion (RPE) and match load (RPE-ML) to compare pre-post-match vertical jump (VJ) capacity according to cerebral palsy (CP) players’ sport classes (i.e., FT1–FT3) and playing positions and to explore whether the neuromuscular performance variation is associated with the internal load of para-footballers with CP. Fifty-six male para-footballers performed two VJ tests before and immediately after a competitive CP football match, followed by measurements of the players’ RPE and RPE-ML. There were no significant differences (p > 0.05) in the pairwise comparisons for RPE and RPE-ML according to sport classes and playing position. A significant reduction in the VJ performance was found for each player sport class and playing position in squat jump (SJ) (p < 0.01; 0.24 < dg < 0.58) and countermovement jump (CMJ) (p < 0.05; 0.22 < dg < 0.45). Regarding the pairwise comparisons, players with the minimal impairment criteria (FT3) obtained higher deficit scores during SJ than those belonging to the FT1 and FT2 (p = 0.003; 1.00 < dg < 1.56). Defenders experienced the lowest performance compared to midfielders and attackers in SJ performance (p = 0.027; 0.94 < dg < 1.28). Significant correlations were obtained between ΔSJ or ΔCMJ and RPE or RPE-ML (r = −0.58 to −0.75; p < 0.001). These findings provide novel information supporting the notion that fatigue induced after a competitive match causes notable impairments in VJ performance differentiated according to sport class and playing position in para-footballers with CP.

Adults with tetraparesis cerebral palsy (i.e., wheelchair users) tend to experience more accelerated ageing, resulting in physical deterioration that increases the impact of the disability, leading to a loss of mobility that interferes with people’s daily activities and participation in the community. The aim of this work is to study the relationship between trunk control and the function of the less-affected arm in this population. For this purpose, 41 para-athletes were invited to participate in this study, performing five tests to assess upper limb coordination, two tests to assess manual dexterity [i.e., Box and Block Test (BBT) and Box and Ball Test (BBLT)] and three tests to assess intra-limb coordination in different planes. Trunk control was assessed in both static and dynamic sitting conditions. The results show moderate correlations between static postural control and manual dexterity tests in the BBT (r = −0.553; p = 0.002) and BBLT (r = −0.537; p = 0.004). Large correlations were also found between static postural control and intra-limb tasks in horizontal (r = 0.769; p = 0.001) and vertical movements (r = 0.739; p = 0.009). Better static trunk control is related to a better upper limb function in the sagittal plane. Considerations and implications are explained in the manuscript.

Similar to conventional football, the modality dedicated to footballers with cerebral palsy (CP) requires referees who cope with the physical demands imposed during competitive matches to apply the rules of the game. While a significant body of research has explored the physical demands on referees in mainstream football, there is a noticeable lack of data regarding CP football. This study aimed to examine the physical response of international referees participating in different levels of world competitions for footballers with CP. Thirteen international referees, who officiated 49 matches in the men’s 2022 World Cup (1st to 15th ranked teams) and 2022 World Championships (16th to 30th ranked teams), participated in this study. A cross-sectional design was used to determine the physical responses and compare the 1st and 2nd halves and the performance in the different tournaments, recording physical variables throughout the matches. Significant higher physical responses were observed in the World Cup in comparison to the World Championship. Overall, high-level tournaments have been shown to elicit more intense physical responses from referees officiating CP football matches compared to lower-level tournaments. For the World Cup, a significantly higher number of accelerations and decelerations were registered in the 1st half compared to the 2nd half. This information may be useful for the strength and conditioning coaches of referees to plan weekly training sessions more specifically and adjust the periodical training load and post-match recovery protocols.

Introduction: Despite the growing emphasis on inclusion, evidence on the longitudinal effects of consecutive training pathways in physical activity remains limited, particularly within initial university-level education. Objective: To assess the impact of a consecutive inclusive physical activity training pathway on the academic and professional development of Physical Activity and Sport Sciences students, focusing on academic self-concept, perceptions of educational inclusion, and evaluations of theoretical and practical training. Method: A longitudinal, quantitative repeated-measures design was employed across one full academic year. University students responded to questionnaires at three time points (R1, R2, and R3), corresponding to key phases of the training pathway. Within-subject analyses were conducted to examine changes over time throughout the complete course sequence. Results: Significant reductions were observed in academic self-concept, perceived academic performance, and academic self-efficacy across the training pathway. Concurrently, significant improvements were found in key dimensions of inclusive practice, particularly in methodology, supports, and community participation, whereas the conception of diversity remained stable. Perceived adequacy of theoretical training increased progressively over time, while perceived adequacy of practical training improved following the first course and subsequently stabilized. Conclusions: The training pathway positively influences students’ preparedness for inclusive education. However, the findings suggest the need to strengthen structured practical experiences that facilitate the transfer of learning to professional practice.

This study aimed to determine the physical performance profile (ability to change direction, vertical and horizontal jump, sprint ability, and dribbling-specific skills) of the first women football players with cerebral palsy (CP) who participated in an international CP football competition, accounting for their sport classes. We also examined the relationships between the different physical performance variables. Forty-five female players with CP (24.9 ± 7.5 years) were categorised into three sport classes based on their impairment severity: 19 were FT1 (severe impairments); 21 FT2; and 5 FT3 (mild impairments). Various physical performance tests were conducted, including the 505 change of direction test; vertical and horizontal jumps; 10 m sprint test; and the dribbling speed test. Significant correlations were observed between the change of direction ability, sprint (r = 0.89; p < 0.01), and dribbling tests (r = 0.71; p < 0.01), as well as between horizontal jump and sprint time (r = − 0.74; p < 0.01). FT1 players demonstrated poorer performance compared to FT3 in the 505 test and standing broad jump (p < 0.05; dg = −1.79 and 1.22 respectively), but also lower vertical jump heights (p < 0.05; dg = −0.91 to −1.57) and increased time required for sprint (p < 0.05; dg = 0.88 to 1.16) and dribbling tests (p < 0.05; dg = 0.85 to 1.44) compared to both FT2 and FT3 players. These findings offer valuable insights into the physical performance characteristics of female footballers with CP, which can guide training and sport enhancement programs for this unique para-sport population.
