Bicycle Set-Up Dimensions and Cycling Kinematics: A Consensus Statement Using Delphi Methodology.

Bicycle set-up dimensions and cycling kinematic data are important components of bicycle fitting and cyclist testing protocols. However, there are no guidelines on how bicycles should be measured and how kinematic data should be collected to increase the reliability of outcomes. This article proposes a consensus regarding bicycle set-up dimensions and recommendations for collecting cycling-related kinematic data.

Empowering women in sports biomechanics: exploring the impact of mentor circles.

This study evaluated the International Society of Biomechanics in Sports (ISBS) women's mentor circle programme. Forty-eight ISBS women members completed a survey that provided insight into how the circles operated, perceived benefits, and challenges to participation. Most circles met every 6-8 weeks with meetings lasting 1 to 1.

Breaking barriers: Exploring female-specific health challenges affecting performance in an elite multisport training environment.

Objectives: Female-specific issues, such as breast injuries, pelvic floor dysfunctions, saddle sores, and menstrual symptoms, can significantly impact female athletes. This study examined the prevalence, perceived impact on performance, and role of the support staff in addressing and managing these issues in elite athletes based at a multisport training centre.

Design: Anonymous online questionnaire.

Investigating Achilles and patellar tendinopathy prevalence in elite athletics.

Although injury surveillance in athletics is routinely conducted, discipline-specific Achilles and patellar tendinopathy prevalence remains unknown. The purpose of this study was to explore discipline-specific tendinopathy prevalence and identify whether injury-specific risk factors differed in athletes. Elite athletes were recruited and provided information on their sport training including Achilles and patellar tendon pain history.

Video Feedback and 2-Dimensional Landing Kinematics in Elite Female Handball Players.

Context:   In team handball, an anterior cruciate ligament injury often occurs during landing after a jump shot. Many intervention programs try to reduce the injury rate by instructing athletes to land more safely. Video is an effective way to provide feedback, but little is known about its influence on landing technique in sport-specific situations.

The effect of leg dominance and landing height on ACL loading among female athletes.

Female athletes are more prone to anterior cruciate ligament (ACL) injury. A neuromuscular imbalance called leg dominance may provide a biomechanical explanation. Therefore, the purpose of this study was to compare the side-to-side lower limb differences in movement patterns, muscle forces and ACL forces during a single-leg drop-landing task from two different heights.

Sex differences in neuromuscular recruitment are not related to patellar tendon load.

Purpose: Although male volleyball players report a greater prevalence of patellar tendinopathy than female players, it remains unknown whether higher patellar tendon loading generated during landing by male players is related to sex-specific neuromuscular recruitment patterns. This study aimed to investigate the relationship between neuromuscular recruitment patterns and patellar tendon loading during landing and to determine whether there were any significant differences in lower limb neuromuscular recruitment patterns displayed by male and female volleyball players during landing.

Methods: The neuromuscular recruitment patterns and patellar tendon loading of 20 male and 20 female volleyball players performing a lateral stop-jump block movement were recorded and calculated.

Lower extremity kinematics and kinetics when landing from unloaded and loaded jumps.

Countermovement jumps loaded with a weighted vest are often used for the training of lower body power to improve jump performance. However, it is currently unknown how this added load affects the lower extremity kinematics and kinetics, in particular whether this results in an increased injury risk. Therefore, the purpose of this investigation was to determine how lower extremity kinematics and kinetics during landing are affected by loaded jumps as demonstrated in a volleyball block jump landing.

Predicting the patellar tendon force generated when landing from a jump.

Purpose: Although high patellar tendon loading is believed to be the primary causative factor for patellar tendinopathy, research investigating factors that affect patellar tendon loading during landing is scarce. Therefore, the purpose of this study was to identify whether factors previously associated with the development of patellar tendinopathy, and selected variables characterizing landing technique, could predict patellar tendon loading incurred by volleyball players when landing from a jump.

Methods: Ten highly skilled male, 20 skilled male, and 20 skilled female volleyball players performed a lateral stop-jump movement.

The effect of assisted jumping on vertical jump height in high-performance volleyball players.

Assisted jumping may be useful in training higher concentric movement speed in jumping, thereby potentially increasing the jumping abilities of athletes. The purpose of this study was to evaluate the effects of assisted jump training on counter-movement vertical jump (CMVJ) and spike jump (SPJ) ability in a group of elite male volleyball players. Seven junior national team volleyball players (18.

Validity and reliability of intra-stroke kayak velocity and acceleration using a GPS-based accelerometer.

The aim of this study was to assess the validity and reliability of the velocity and acceleration measured by a kayak-mounted GPS-based accelerometer units compared to the video-derived measurements and the effect of satellite configuration on velocity. Four GPS-based accelerometers units of varied accelerometer ranges (2 g or 6 g) were mounted on a kayak as the paddler performed 12 trials at three different stroke rates for each of three different testing sessions (two in the morning vs. one in the afternoon).
