The purpose of this study was to describe running economy, soccer specific endurance, and selected kinematic running criteria in soccer players with cerebral palsy (SPCP) and to compare them with values of position-matched players without CP. Fourteen international, male soccer players with cerebral palsy completed the "Yo-Yo" intermittent recovery run level 1 (IRL-1) test to assess soccer-spec...

BACKGROUND High intensity intermittent aerobic exercise is an elementary endurance training exercise to build soccer endurance. Many studies exist with professional soccer players. But limited research has been conducted with amateur soccer players. OBJECTIVES The aim of this study was to compare and assess the effects of the shuttle-run method and the Hoff-track method on the ability to reco...

Canadian female junior soccer players were evaluated for their anthropometrical characteristics including somatotype and body composition with a aim to evaluate with their international counterparts. 18 female soccer players with an average age of 16(±0.5) of a local club were assessed during their peak season time . Somatotype was assessed using HeathCarter method and body composition ( Fat%) ...

Does frequent head-to-ball contact cause cognitive dysfunctions and brain injury to soccer players? An iPad-based experiment was designed to examine the impact of ball-heading among high school female soccer players. We examined both direct, stimulus-driven, or reflexive point responses (Pro-Point) as well as indirect, goal-driven, or voluntary point responses (Anti-Point), thought to require c...

BACKGROUND A recent study published in The American Journal of Sports Medicine showed that asymptomatic soccer players with an increased risk of developing Achilles and patellar tendon injuries within the next 12 months can be identified with use of ultrasonography. HYPOTHESIS Prophylactic eccentric training and stretching can reduce both the frequency of asymptomatic ultrasonographic changes...

Soccer participation, especially among females, is growing in popularity in the United States. Purposeful heading, an important soccer skill, has recently been scrutinized for safety reasons. The purpose of this study was to determine whether there was a relationship between purposeful heading and scores on cognitive function and balance in high school and collegiate female soccer players. Prio...

Chronic traumatic encephalopathy (CTE) was initially described in boxers, but in recent years it has been reported in other settings, particularly in contact sports and military personnel. Soccer (football association) had previously been (and still is) considered relatively safe when compared to other sports, such as American football. However, a few cases of professional soccer players with C...

Excellent physical performance of soccer players is inevitable for the success of a team. Despite of this, a large-scale, quantitative analysis of the maximal speed of the players is missing due to the sensitive nature of trajectory datasets. We propose a novel method to derive the in-game speed profile of soccer players from event-based datasets, which are widely accessible. We show that eight...

UNLABELLED There is a lack of studies concerning hydration status of young athletes exercising in the heat. PURPOSE To assess preexercise hydration status in young soccer players during a summer sports camp and to evaluate body- water balance after soccer training sessions. METHODS Initial hydration status was assessed in 107 young male soccer players (age 11-16 yr) during the 2nd day of th...

Two core elements for the coordination of different actions in sport are tactical information and knowledge about tactical situations. The current study describes two experiments to learn about the memory structure and the cognitive processing of tactical information. Experiment 1 investigated the storage and structuring of team-specific tactics in humans' long-term memory with regard to differ...
