Training load monitoring systems in football do not focus on lower extremities and therefore potentially neglect important information to optimise performance or reduce injury risk. The current study aims to present joint and segment angular accelerations as novel indicators to quantify lower extremity biomechanical load measured by a new inertial...
Article
Full-text available
Athletes are exposed to various psychological and physiological stressors, such as losing matches and high training loads. Understanding and improving the resilience of athletes is therefore crucial to prevent performance decrements and psychological or physical problems. In this review, resilience is conceptualized as a dynamic process of bouncing...

Full-text available
Introduction: Performance assessment in professional soccer often focusses on notational assessment like assists or pass accuracy. However, rather than statistics, performance is more about making the best possible tactical decision, in the context of aplayer’s positional role and the available options at the time. With the current paper, we aim to...
Article
Full-text available
Decision-makers in soccer routinely assess the tactical behaviour of a team and its opponents both during and after the game to optimize performance. Currently, this assessment is typically driven by notational analysis and observation. Therefore, potential high-impact decisions are often made based on limited or even biased information. With the c...
Article
Full-text available
It has been claimed that increased reliance on context, or allocentric information, develops when aiming movements are more consciously monitored and/or controlled. Since verbalizing target features requires strong conscious monitoring, we expected an increased reliance on allocentric information when verbalizing a target label (i.e. target number)...
Article
Full-text available
ABSTRACT Association football teams can be considered complex dynamical systems of individuals grouped in subgroups (defenders, midfielders and attackers), coordinating their behaviour to achieve a shared goal. As research often focusses on collective behaviour, or on static subgroups, the current study aims to analyse spatiotemporal behaviour of d...
Article
In elite basketball, players are exposed to intensified competition periods when participating in both national and international competitions. How coaches manage training between matches and in reference to match scheduling for a full season is not yet known.

Participants made visually and memory-guided pointing and swiping gestures with a stylus to targets located in a semicircle. Specific differences in aiming er...
Article
Injuries of runners reduce the ability to train and hinder competing. Literature shows that the relation between potential risk factors and injuries are not definitive, limited, and inconsistent. In team sports, workload derivatives were identified as risk factors. However, there is an absence of literature in running on workload derivatives. This...
Article
Full-text available
Current athlete monitoring practice in team sports is mainly based on positional data measured by global positioning or local positioning systems. The disadvantage of these measurement systems is that they do not register lower extremity kinematics, which could be a useful measure for identifying injury-risk factors. Rapid development in sensor tec...
Article
Full-text available
Inertial sensor-based measurements of lower body kinematics in football players may improve physical load estimates during training sessions and matches. However, the validity of inertial-based motion analysis systems is specific to both the type of movement and the intensity at which movements are executed. Importantly, such a system should be rel...
Article
Full-text available
In professional soccer, increasing amounts of data are collected that harness great potential when it comes to analysing tactical behaviour. Unlocking this potential is difficult as big data challenges the data management and analytics methods commonly employed in sports. By joining forces with computer science, solutions to these challenges could...

There was an error in the calculation of the standard deviation of the continuous relative phase measure (SDϕ). The standard deviation was calculated on the absoluted continuous relative phase values. Therefore, the reported SDϕ‐values were underestimated. As such, in the present erratum we based the relation between crew coordination consistency a...

Conference Paper
Full-text available
Crew rowing is often quoted as a natural example of perfect unity. A crew of rowers aims to optimize performance by perfectly moving in synchrony, while they apply all their power at maximum stroke rate. But do they necessarily need to move in in-phase synchrony? It has been suggested that crew members may complement each other’s movements by rowin...

Small-sided games (SSGs) are a promising training format in soccer to replicate (situations of) the official match across all age groups. Typically, SSGs are played on a smaller relative pitch area (RPA; i.e., ,150 m2) than the match (320 m2 RPA), which results in different tactical demands. To create a more precise replication of tactical match de...

Conference Paper
Full-text available
In crew rowing, agents need to coordinate their movements to achieve optimal performance. Although, traditionally, rowers aim to move perfectly in sync, it has been suggested that rowing in antiphase may actually be mechanically more efficient. From coordination dynamics, the antiphase pattern is expected to be less stable, especially with an incre...
Article
How do outfielders control their locomotor behavior in running to catch fly balls? This question has been the topic of many empirical studies. It is interesting that a little addressed but highly relevant issue in this regard is that of the influence of perceived catchability on locomotor control. We examined what factors determine catchability and...
Conference Paper
Full-text available
Traditionally, rowers aim to row perfectly in sync (in-phase coordination) to achieve optimal performance. However, it has been suggested that when rowers perfectly alternate their strokes (i.e., antiphase coordination), velocity fluctuations of the boat are minimized, which reduces power losses to 5% [1,2] and hence might theoretically result in a...

Article
Full-text available
Small-sided games (SSGs) are used in training sessions to prepare for full-sized matches. For the same number of players, smaller pitch sizes result in decreased physical performance and shorter interpersonal distances. A relative pitch area derived from the full-sized match results in larger pitch sizes and this may increase the fit between SSGs a...

Article
Background: Hop tests are frequently used to determine return to sports (RTS) after anterior cruciate ligament reconstruction (ACLR). Given that bilateral deficits are present after ACLR, this may result in a falsely high limb symmetry index (LSI), since LSI is calculated as a ratio between the values of the limbs. Hypothesis: Athletes after ACL...

Tactical match performance depends on the quality of actions of individual players or teams in space and time during match-play in order to be successful. Technological innovations have led to new possibilities to capture accurate spatio-temporal information of all players and unravel the dynamics and complexity of soccer matches. The main aim of t...
Article
In crew rowing, crew members need to mutually synchronize their movements to achieve optimal crew performance. Intuitively, poor crew coordination is often deemed to involve additional boat movements such as surge velocity fluctuations, heave, pitch, and roll, which would imply lower efficiency (eg, due to increased hydrodynamic drag). The aim of t...
Article
Video feedback may be a powerful tool to change biomechanical landing patterns associated with anterior cruciate ligament (ACL) injury risk. This study investigated the effect of video feedback on drop vertical jump (DVJ) landing strategies in team sport athletes. 59 athletes were assigned to a video feedback (VI) or control (CTRL) group. A pretest...
Conference Paper
Full-text available
In crew rowing, agents need to coordinate their movements while physically connected through the boat they share. Modelling a rowing crew as a system of coupled oscillators predicts that the stability of crew coordination decreases with increasing stroke rate. However, rowing literature suggests that crew synchronisation might actually improve at h...
