Soccer flexibility

Neil Light
BACKGROUND: Deficits in adductor strength and flexibility are known risk factors for soccer hip/groin injury, yet little is known about the acute effects of soccer match play on these physical features. The aim of this study therefore was to examine the changes in adductor strength and flexibility before; during and immediately after soccer match play. METHODS: Design: Twenty, male university soccer players (age = 22.35 ± 1.98 years) participated in this field-based, within subject, repeated measures study...

The paper analyses two datasets of elite soccer players (top 1000 professionals and UEFA Under-19 Youth League). In both, we find a Relative Age Effect (RAE) for frequency, but not for value. That is, while there are more players born at the start of the competition year, their transfer values are no higher, nor are they given more game time. We use Poisson regression to derive a transparent index of the discrimination present in RAE. Also, because Poisson is valid for small frequency counts, it supports analysis at the disaggregated levels of country and club...

Soccer is the most popular sport worldwide. Despite its global acclaim, scientific studies of soccer have tended to focus on tactics and techniques, thereby neglecting the physical and physiological profile of the players. Therefore, the purpose of this study was to examine physical and anthropometric characteristics of male South African university soccer players. Twenty-seven male soccer players aged 19 to 24 (mean age: 22.1 years; s = 1.5 years) volunteered to participate in the study. The results showed that goalkeepers (77...

Foam rolling (FR) is a common strategy used after training and competition by players. However, no previous studies have assessed the effectiveness of FR as recovery tool in sports populations. The aim of this study was to examine the effectiveness of FR (20 minutes of foam rolling exercises on quadriceps, hamstrings, adductors, gluteals, and gastrocnemius) and passive recovery (20 minutes sit on a bench) interventions performed immediately after a training session on Total Quality Recovery (TQR), perceived muscle soreness, jump performance, agility, sprint, and flexibility 24 hours after the training...

Soccer is characterized by high aerobic demands interspersed with frequent bursts of anaerobic activity. High-intensity interval training (HIIT) is considered a viable alternative to traditional endurance conditioning and offers the additional time-saving benefits of anaerobic training. We hypothesized that HIIT will compare favorably to traditional (aerobic-based) soccer conditioning over the course of a high school soccer season. Junior varsity soccer players were split into control (CON, n=16) and experimental (HIIT, n=16) groups for the 10-week study...

Sports injuries and athletic performance are complex areas, which are characterized by manifold interdependencies. The landing error scoring system (LESS) is a valid screening tool to examine bilateral jump-landing mechanics. Whereas, the Functional Movement Screen (FMS) items are thought to operationalize flexibility and motor behaviour during low intense bodyweight patterns. The aim of the study was to explore possible interdependency of the diagnostic information of these screening tools. 53 athletes (age 23...

There are three major questions about return to play (RTP) after hamstring injuries: How should RTP be defined? Which medical criteria should support the RTP decision? And who should make the RTP decision? The study aimed to provide a clear RTP definition and medical criteria for RTP and to clarify RTP consultation and responsibilities after hamstring injury. The study used the Delphi procedure. The results of a systematic review were used as a starting point for the Delphi procedure. Fifty-eight experts in the field of hamstring injury management selected by 28 FIFA Medical Centres of Excellence worldwide participated...

Cricoarytenoid joint subluxation is rare condition. There are <200 cases reported in the English literature. The most frequent cause of this condition is a traumatic tracheal intubation which account for approximately 80 % of all cases. The most common symptoms are dysphonia and pain of the anterior region of the neck which appear after upper airway manipulation or cervical trauma. In this report we present a well-documented case of a 31 year old male that was referred to the outpatient clinic because of acute dysphonia and pain that appeared immediately after receiving a blow of a soccer ball...

Performance and injury prevention in elite soccer players are typically investigated from physical-tactical, biomechanical, and metabolic perspectives. However, executive functions, visuospatial abilities, and psychophysiological adaptability or resilience are also fundamental for efficiency and well-being in sports. Based on previous research associating autonomic flexibility with prefrontal cortical control, we designed a novel integrated autonomic biofeedback training method called Neuroplus to improve resilience, visual attention, and injury prevention...

An optical ice microscope apparatus equipped with a sealed cooling stage and a CCD camera was used to examine contact freezing events between a water droplet and ice nucleating particles (INP) containing organic hydrocarbons including octacosane, squalane, and squalene. Sample viscosities were measured with a capillary viscometer and compositions were characterized using Fourier transfer infrared spectroscopy with horizontal attenuated total reflectance and Raman microspectroscopy. All of the samples proved to be moderately efficient ice nuclei that induced freezing between -23 and -26 °C, regardless of whether the INP was solid or liquid...

BACKGROUND: Numerous studies have analyzed during competitive season different conditioning programs to improve soccer players' repeat sprint ability (RSA). However, few studies have focused on analyzing what happens with this ability after small-sided-game- (SSG-) -based training. Thus, the aim of this study was to determine the changes in physical performance after 5 weeks of pre-season training composed of SSGs in amateur soccer players. METHODS: Twenty-four male soccer players performed RSA, a sit-and-reach and two vertical jump (squat and countermovement jump) tests before and after 5 weeks of pre-season training mainly consisting of SSGs...

CONTEXT: The Star Excursion Balance Test (SEBT) and Functional Movement Screen (FMS) are functional performance measures capable of predicting lower-extremity injury risk. While suboptimal SEBT and FMS performances are influenced by multiple factors, the contribution of hip strength and flexibility to these tests is mostly unknown. Examination of hip strength and flexibility influences on the SEBT and FMS may direct clinicians to better methods of correcting functional deficits. OBJECTIVE: Determine the relationships of isometric hip strength and hip passive range of motion (PROM) with functional performance measures...
