Purpose There are several approaches to quantifying physical load in team sports using positional data. Distances in different speed zones are most commonly used. Recent studies have used acceleration data in addition in order to take short intense actions into account. However, the fact that acceleration decreases with increasing initial running s...

Purpose This study compared the validity and inter- and intra-unit reliability of local (LPM) and global (GPS) position measurement systems for measuring acceleration during team sports. Methods Devices were attached to a remote-controlled car and validated against a laser. Mean percentage biases (MPBs) of maximal acceleration (amax) and maximal r...

In many sports the importance of explosive strength as performance predictor in fast acyclic and cyclic movements has grown. Explosive strength testing is used already in young athletes to optimize the physical training in a long-term performance development process. Age and sport specific reference values may help to exactly evaluate the individua...

Purpose:: This study investigates the strengths and limitations of different indicators to measure physical load. Furthermore, indicators were evaluated for discrimination between performance levels and playing positions. Methods:: Ninety positional match files from 70 elite players and 91 match files from 69 sub-elite players were collected dur...

In recent years, the availability of new tracking technologies has enabled new perspectives on passes played in football. One such perspective includes measuring the number of opponents that are outplayed by a pass (NOO). Various studies substantiate that this measure qualifies as one aspect of the passes’ offensive quality. Given the latent consen...

Passes are a performance-relevant parameter in many team sports. They must be played in the highly dynamic and unpredictable contexts of interactive team competitions. The difficulty to plan passes in advance requires real-time decisions and highlights the importance of the information provided by current game contexts. This study estimates the rel...

Sprint actions are important in soccer and are often performed over short distances and from different initial speeds. Traditionally, absolute speed thresholds (e.g. >7 m/s) have been used to identify sprint actions, whereas newer studies have introduced individual speed thresholds. Recently, it was postulated that, additionally, an absolute accele...

Explosive leg strength in Swiss elite youth athletes In many sports the importance of explosive strength as per-formance predictor in fast acyclic and cyclic movements has grown. Explosive strength testing is used already in young athletes to optimize the physical training in a long-term per-formance development process. Age and sport specific refe...

A certain level of athletic performance is required to become an elite player in women’s soccer. Some studies with male soccer players show significant development in performance from adolescence to adulthood, but no such studies have been conducted for female players. The aim of this longitudinal study is to detect possible changes in the anthropo...

Sprinting plays an important role in elite female soccer (Andersson, 2010). From interest in soccer are three different sprint categories: acceleration, maximum speed and agility (Little, 2005). To improve sprinting, it is crucial to understand its limiting factors. Salaj and Markovic (2011) examined the specific jumping, sprinting and agility leve...

There exist differences between male’s and female’s football (Kirkendall 2007). Male players cover for instance more distance in high intensity running than women during match play (Mohr 2008). It is assumed that male’s football is also technically more advanced although there are limited data. In order to benefit from the higher physical and techn...

Es ist bekannt, dass sich im Mannschaftssport die physischen und physiologischen Anforderungen je nach Spielposition unterscheiden (Di Salvo, 2007). Studien von Chaouachi (2009) und Sibila (2009), welche positionsspezifische Unterschiede hinsichtlich körperlicher und leistungsrelevanter Parameter bei Handballspielern erfassten, sind die ersten in d...

Die zyklisch, elementare Bewegungsschnelligkeit (EBS) ist in Spielsportarten von Bedeutung. Aufgrund der Komplexität der EBS und des hohen Leistungsniveaus bei Elite-Spielsportlern mit entsprechender Homogenität sollten leistungsdiagnostische Verfahren zur Erfassung und Beurteilung der EBS aus verschiedenen Tests zusammengesetzt werden. Die Magglin...

In vielen Sportarten spielen plyometrische Trainingsformen eine wichtige Rolle in der Steigerung der Explosivkraft der unteren Extremitäten. Plyometrische Trainingsformen bestehen aus einem sogenannten Dehnungs-Verkürzungs-Zyklus (DVZ), bei welchem die exzentrische Dehnungsphase durch Verwendung von elastischer Energie und Reflexaktivierung des neu...
