The aim of this study was to investigate the effect of the swivel seat on kinematics and performance during sprint paddling on an ergometer. Nine experienced kayakers volunteered for this study and each completed two maximal trials of 30 s on the ergometer, one with the swivel seat and the other with a fixed seat. Three-dimensional motion analysis and performance data were collected at 200 Hz during the central 10 s of each trial. The use of the swivel seat was observed to improve performance through a significant increase in peak fly-wheel RPM (p = 0.033) and paddle antero-posterior displacement (p = 0.015) and a significant decrease in right side paddle recovery time (p = 0.043). In conclusion, the use of the swivel seat was associated with kinematic changes that improved performance and decreased the risk of excessive spine rotation. These results offer new insights into understanding the implications of swivel seat use for the dynamics of kayaking.","PeriodicalId":49482,"journal":{"name":"Sports Biomechanics","volume":" ","pages":"1-15"},"PeriodicalIF":2.0,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143442559","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

According to previous biomechanical studies, jump heights do not change significantly even with more rotational jumps. However, strategies employed by top skaters to acquire new jumps are unclear. Therefore, this study aimed to investigate specific kinematic strategies used by skaters to perform the quadruple axel jump (4A), focusing on two skaters (skaters A and B) who attempted this jump in competitions. Using data from the Ice Scope tracking system, this study analysed the vertical height, horizontal distance, take-off speed, landing speed, and height-to-distance ratio of the jumps. Both skaters achieved higher vertical heights in their 4A attempts than in their triple axel jump (3A) attempts. Notably, Skater A's successful 4A and Skater B's downgraded 4A had significantly greater vertical heights than the average 3As among world-class skaters. This suggests a strategic shift towards increasing the vertical height to master 4As, contrary to previous biomechanical research that did not emphasise vertical height. These findings update existing theories on figure skating research and provide insights into training strategies for mastering difficult jumps.","PeriodicalId":49482,"journal":{"name":"Sports Biomechanics","volume":" ","pages":"1-12"},"PeriodicalIF":2.0,"publicationDate":"2025-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143416007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lateral footwork is crucial in tennis, and variations in the athletes' physical characteristics can affect footwork efficiency. Flat feet hinder forward propulsion; however, their relationship to lateral propulsion remains unclear. Thus, this study focused on foot morphology among other physical traits. Seventeen male university tennis players were evaluated using the navicular drop test and categorised into the flat foot (eight participants) and normal foot (nine participants) groups. The kinematic and kinetic data during the crossover step movements were collected using a three-dimensional motion analysis system and force plates. Although no significant intergroup differences in lateral propulsion, represented by the lateral peak acceleration of the centre of mass, were observed, individuals with flat feet exhibited significantly higher ankle maximum dorsiflexion angles and maximum eversion moments than those with normal feet. Individuals with flat feet are likely to compensate for functional deficits by increasing muscle activity, which may increase the risk of injury. Further research on muscle activity during sports movements and injury prevalence is necessary to improve the prevention and treatment strategies.","PeriodicalId":49482,"journal":{"name":"Sports Biomechanics","volume":" ","pages":"1-12"},"PeriodicalIF":2.0,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143383659","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the measurement of throwing pole forces in seated shot put has not been reported previously in the research literature, leading to a considerable barrier to a better understanding and optimisation of performance. In this research, the first set of pole force measurements in seated throwing is presented, along with a comparison between two methods for such measurement: a direct load-sensing and a deflection-based method, where the latter requires considerably less specialised equipment than the former. From this, the measurement of pole forces without an instrumented pole is found to be feasible (RMSE < 10%), thus providing a simpler option for the measurement of pole forces in seated throwing. In addition, unexpected resonant pole effects (5-6 Hz) are observed during the throw which may have an interaction with the way athletes apply force to the pole. The methods and findings presented are intended to provide a platform for future research.","PeriodicalId":49482,"journal":{"name":"Sports Biomechanics","volume":" ","pages":"1-12"},"PeriodicalIF":2.0,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143257127","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fifty-five random static positions in a gym (54.8 × 26.0 m) were obtained 10 times via LPS (50 Hz) and measuring tape. An athlete's LPS-derived peak and time-series speed and acceleration during dynamic movements (n = 80) were compared with Vicon (100 Hz). Reliability and validity were assessed via Intraclass and Concordance Correlation Coefficients (ICC/CCC), root mean square errors, Bland-Altman plots, and analysis of variance. ICC3,1 (≥0.999) and CCC (0.387-0.999) were calculated for static positions (errors <0.22 m). CCC for time-series speed and acceleration, and peak speed, acceleration, and deceleration were 0.884-0.902, 0.777-0.854, 0.923, 0.486, and 0.731, respectively.

Participants between 18 to 35 years performed unanticipated 'change in direction' trials at their maximal self-preferred speed. The maximal knee flexion angle and the valgus moment of the right knee during the weight acceptance phase were analysed. MRI data (T2 relaxation time) of the ACL was also collected.

Sprint times were significantly reduced in the acceleration and MV phase, with a homogeneous individual response within the group. There were no significant alterations in the angles of the trunk, hip, thigh, knee, shank, ankle and foot across the different tests, nor in SR. Significant alterations in CoM-angle, step velocity and higher SL were observed.

The three-dimensional motion analysis and measurement of surface electromyography for the left lower limb were performed. The fluid forces acting on the body and joint torques were estimated using Swumsuit simulator. As the results, the kick amplitude and range of joint motion were smaller for the UFK than for the UDK, and the muscle activity and the peak joint torques of the hip and knee were lower for the UFK than for the UDK. Furthermore, the estimated propulsion for both the downward and upward kicks was lower for the UFK than for the UDK.
