However, collecting kinematic data on the volleyball court remains challenging. This study investigated landing kinematics between dominant and non-dominant lower limbs during stop-jumps on the volleyball court and analysed landing variables to identify biomechanical patterns associated with high knee angular accelerations. Landing kinematics were quantified using 3D markerless motion capture (OpenCap) with two cameras. Fourteen male and 5 female elite volleyball players performed 10 stop-jump landings while approaching the net to spike a ball over the net. Asymmetry was found with the dominant limb landing in greater plantarflexion and hip flexion but less knee flexion. The dominant limb exhibited higher knee angular velocities (mean ± standard deviation: dominant = 274 ± 62°/s, non-dominant = 169 ± 84°/s; p < 0.001) and accelerations (dominant = 3924 ± 2221°/s2, non-dominant = 1441 ± 4278°/s2; p = 0.032), suggesting greater biomechanical load. High knee accelerations were significantly correlated with limited knee and hip flexion in the dominant limb, closer foot position, greater trunk flexion at non-dominant limb touchdown, and longer contact time with the non-dominant limb (Pearson's correlation coefficient; |0.55| ≤ r ≤ |0.79|, p < 0.018). OpenCap provided valuable insights into volleyball stop-jump kinematics. Therefore, markerless motion capture can provide coaches and scientists with a deeper understanding of landing performance and related injury mechanisms.","PeriodicalId":17066,"journal":{"name":"Journal of Sports Sciences","volume":" ","pages":"1296-1306"},"PeriodicalIF":2.5,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143988500","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While laboratory-based motion capture is considered gold-standard, markerless motion capture (MMC) systems offer an accessible alternative for field and clinical settings. However, their validity and reliability vary, warranting a comprehensive synthesis of current literature. Six databases (CINAHL, Embase, MEDLINE, Scopus, SPORTDiscus, Web of Science) were searched following PRISMA for studies comparing MMC derived kinematics, kinetics or performance with gold-standard measures during vertical or horizontal jump tasks. Twenty studies met inclusion. The meta-analysis for sagittal-plane pooled root mean square error (RMSE) values were 5.3° for hip (95% CI 2.9-7.6°), 4.4° for knee (2.9-5.9°) and 4.9° for ankle (3.9-5.9°). Frontal-plane RMSE values were 3.0° for hip (2.5-3.5°) and 7.5° for ankle (4.1-10.9°). Pooled jump-height bias was -2.9 cm (-8.1 to 2.3 cm). Between-study heterogeneity ranged from low to substantial, with wider prediction intervals for sagittal hip, frontal ankle and jump height. This review suggests that current MMC systems can achieve moderate accuracy for lower limb jump biomechanics, but performance varies widely between systems and contexts. Practitioners should consider system-specific evidence to make informed decisions regarding the suitability of a given system for their needs.","PeriodicalId":17066,"journal":{"name":"Journal of Sports Sciences","volume":" ","pages":"1275-1295"},"PeriodicalIF":2.5,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145604764","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Five databases (Scopus, Web of Science, CINAHL Complete, SPORTDiscus, and MEDLINE Complete) were searched from inception to November 2025. Studies that investigated surfing skill, physical performance or injury profiles in both male and female participants were included. Of 4729 studies identified, 50 met the inclusion criteria. These included 10 studies on surfing skills, 17 on physical performance, and 32 on injury profiles. Studies included outcome measures with sex-specific comparisons for skill (70%), physical performance (64%) and injury (19%). Overall, sex comparisons were made consistently in five (14%) outcome measures across all study concepts. Limited research on sex-specific injury profiles restricts the development of injury prevention strategies for female surfers. As the literature evolves in surfing, researchers should maximise the value of their data by reporting on sex-specific differences, appropriately normalising values (where necessary) and utilising consistent testing approaches.","PeriodicalId":17066,"journal":{"name":"Journal of Sports Sciences","volume":" ","pages":"1215-1227"},"PeriodicalIF":2.5,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147377911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We compared markerless motion capture (ML)(Theia Markerless) to the reference method, marker-based motion capture (MB)(CORTEX). Three-dimension kinematic data from MB and ML systems and ground reaction force were collected simultaneously for 14 participants, at three stages of the sprint acceleration spectrum (early, middle acceleration and top speed). Sagittal plane angles for the foot, ankle, shank, knee, thigh, hip, pelvis and trunk were computed through biomechanical modelling. Analysis on the whole curves showed reasonable reliability for all sprint running phases for all angles and joints except hip, pelvis and foot at top speed. Discrete points analysis identified greater discrepancies at top speed touchdown. These contrasting results do not allow for clear conclusions about the ability of ML technology to reliably quantify sprint kinematics in the sagittal plane, especially regarding the pelvis. However, due to some limitations of both methodologies (soft tissue vibration (MB) and joint center position accuracy (ML)), it is not clear whether these inter-system differences are due to inaccuracies of one system or the other, or a combination of both.","PeriodicalId":17066,"journal":{"name":"Journal of Sports Sciences","volume":" ","pages":"1334-1347"},"PeriodicalIF":2.5,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144608653","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Twelve couples performed three dyadic movements: the walk high-five, dribble simulation, and double sidestep. Movements were simultaneously recorded with both systems. For each movement, the segment orientations, joint angles and center of mass were compared using the standardized typical estimate of the error, correlation coefficient, root mean squared difference (RMSD), and Bland-Altman analysis. There was an acceptable agreement in all segment orientations (RMSD < 12.5°), except for the hand segment. The flexion/extension joint angles showed an acceptable similarity between the two systems, excluding the wrist. There was a close-to-perfect similarity and agreement in the center of mass overall movement tasks.

Applying Growth Mixture Modelling, we found that a 4-class model best fits the male sample, while a 5-class model fits the female sample most optimally. The best male class displayed non-linear development, improving slowly until age 13.5, after which development accelerated. The best female class showed consistent linear improvement. The correlation between performance at age 16 and preceding ages increased during adolescence. The correlation starts off moderate at slightly above 0.6 at age 11.5 and increases steadily to almost 1.0 at age 15.5. The correlation was consistently higher for the female sample.
