Normative data of Lower-limb muscle flexibility in futsal players

El objetivo de este estudio fue definir cuantitativamente los valores de referencia del perfil de flexibilidad en 20 jugadores profesionales de fútbol sala. Para ello se valoró la flexibilidad de los principales grupos musculares de la extremidad inferior a través de 7 pruebas de rango de movimiento articular pasivo máximo. Los resultados obtenidos demuestran que los jugadores de fútbol sala analizados presentan un perfil de flexibilidad de la extremidad inferior superior a los valores propuestos para población general, a los valores encontrados en sujetos sanos sedentarios, así como en personas físicamente activas. De la misma forma, los valores de flexibilidad de los jugadores de fútbol sala seleccionados son superiores a los observados en otras modalidades deportivas.The purpose of this study was to quantitatively define the normative lower-limb flexibility data in 20 professional futsal players. For it, the flexibility of the major lower-limb muscles was evaluated throughout 7 different peak joint ROM assessment tests. The results of the current study demonstrate that the professional futsal players assessed have higher normative data of lower-limb flexibility than the previously stabilised flexibility normative data for general population, healthy sedentary adults, as well as for recreationally active adults. Likewise, the normative lower-limb flexibility data for the professional futsal players selected are higher than those reported for other sport modalities

Optimal data of lower-limb muscle flexibility in female futsal players

El objetivo fue definir cuantitativamente los valores del perfil óptimo de flexibilidad en 20 jugadoras de fútbol sala. Para ello, se valoró la flexibilidad de los principales grupos musculares del miembro inferior a través de 7 pruebas de rango de movimiento pasivo máximo (ROM). Los resultados del presente estudio definen como ROM óptimo los siguientes rangos para las jugadoras de campo: 43º-52º para gemelo, 48º-54º para sóleo, 148º-154º para glúteo mayor, 99º-118º para musculatura isquiosural, 46º-56º para aductores, 12º-20º para psoas iliaco y 116º-129º para cuádriceps. Para las porteras se han obtenido los siguientes rangos: 40º-46º para gemelo, 40º-47º para sóleo, 150º-155º para el glúteo mayor, 94º-118º para musculatura isquiosural, 45º-54º para aductores, 8º-12º para psoas iliaco y 115º-133º para cuádriceps. Teniendo en cuenta que se ha definido el percentil >80 como el ROM óptimo, sólo 4 jugadoras de campo y 2 porteras presentaban este ROM en cada movimiento evaluadoThe purpose of this study was to define the optimal lower-limb flexibility data for 20 female futsal players. Therefore, the flexibility of the major lower-limb muscles was evaluated throughout 7 different passive range of motion (ROM) assessment tests. The results of this study define the optimal ROM ranges for field players as: 43º-52º for the gastrocnemius, 48º-54º for the soleus, 148º-154º for the gluteus maximus, 99º-118º for the hamstrings, 46º-56º for the adductors, 12º-20º for the iliopsoas, and 116º-129º for the quadriceps. For goalkeepers have obtained the following ranges: 40º-46º for the gastrocnemius, 40º-47º for the soleus, 150º-155º for the gluteus, 94º-118º for the hamstrings, 45º-54º for the adductors, 8º-12º for the iliopsoas, and 115º-133º for the quadriceps. Keeping in mind that optimal ROM values were defined as >80th percentile, only 4 field players and 2 goalkeepers presented this ROM values in each movement assessed

Football training program and injury prevention program WTA: a season of analysis with IT management Weakrisk Sporstsolutions in Italan élite football players third division (Serie C).

Purpose: The aim of this study is analyze the relationship with training program and injury prevention program in professional football players during competitive season in AJ Fano Calcio 1906 srl (Italian 3rd Division Serie C, 2019-2020). In fact, it is very important for the team to try to minimize or greatly reduce the incidence of injuries to ensure a better choice of players available to the coach according to the match. Our analysis will try to better understand the importance of creating an adequate postural set up by optimizing the functioning of the muscle kinetic chains, during the pre-training phase. Twenty eigth (n=28) élite football players took part in this study (age 21.4±3.3; body weigth 79.7±3.4 ; heigth 182.4±5.5 ; fat mass 9.2±1.9 ; ), without goalkeepers. In pre-season (4 weeks, from july to august) and during a season (december) the players performed yo yo intermittent recovery test level 2 (IR2), to evaluate aerobic and anaerobic performance before the start of season. At same time the players perfomed jump test (SJ, CMJ, CMJAS, JUMPS 15’’), with Optojump Microgate (Microgate, Bolzano, Italy). Every players has been analyzed with K-GPS Live 50Hz (K-Sport Universal STATS, Montelabbate (PU), Italy) and Polar Team System PRO 2 (Polar Electro, Finland, OY) to recorder maximal heart rate during a intermittent test and official match. Every players has done from July (start preseason) to February (in season), 300 sessions of WTA primitive prevention training program before and after training to preparare muscle chains to daily workout, 244 training during this period. Pre and post training program, performed on a daily basis, highlighted that AJ Fano Calcio 1906 srl, total incidence injury is 3.14/1000h, training incidence injury is 1.34/1000h and match incidence injury is 23.6/1000h, respectively - 23.4% to UEFA data total incidence injury (4.1/1000h), -46.4% to UEFA data training incidence injury (2.5/1000h) and 22.3% to Uefa data match incidence injury (19.3/1000h). Infact, this improvement in match injury (contact and non-contact), probabily due, to difference level of football players: in professional third division there are players that have a reduced coordination and intervention times compared to top level players. This element is clear also in different energy cost (í) from different players level during official matches: first division (21.7±0.7%) vs third division (27±2.5%) (ES=3.05, p<0.05). This event represent energy expenditure during a match: third division has low physical, technical and tactical quality compare first division pro and players have high energy expenditure levels. Probabily our hypothesis on this type of prevention program (primitive WTA) should be used already started youth to prepare muscle chains and improve coordination and movements in future athletes to reduce injuries

Programas de entrenamiento neuromuscular para la prevención de lesiones en jóvenes deportistas. Revisión de la literatura.

The aims of this review are: (1) describing the principal lower extremity injury prevention programs in young athletes that have a demonstrated efficacy, whose prevention have been destined for ball team sports, do not require any additional material for their application and the duration allows for their implementation as previous warm-upprograms; and (2) analyzing the advantages and disadvantages of the prevention strategies according to their possibility of implantation in the regular sport practice. For this purpose, a total of 5 neuromuscular injury prevention programs were selected. Although all the programs have shownpositive effects in terms of the reduction of sport injury incidence, the detailed analysis of the characteristics of the prevention strategies recommend the utilization of the FIFA 11+ and Knäkontroll programs for their greater adaptability to the application context and their facility for the implementation in the regular sport practice.Los objetivos de esta revisión son: (1) describir los principales programas de prevención de lesiones de la extremidad inferior en jóvenes deportistas que cuentan con una eficacia demostrada, cuya prevención ha estado dirigida a deportes colectivos de balón, no requieren de material adicional para su aplicación y la duración permite su implementación como calentamiento previo a la práctica deportiva; y (2) analizar las ventajas e inconvenientes de las medidas preventivas de acuerdo a su posibilidad de implantación de manera regular en el deporte. Para ello, un total de 5 programas neuromuscularespara la prevenciónde lesiones fueron seleccionados. Aunque todos los programas han demostradoefectos positivossobre la reducción de la incidencia lesional, el análisis pormenorizado de las características de las 5 medidas preventivas recomienda el uso de los programas FIFA 11+ y el Knäkontroll por su mayor adaptabilidad al contexto de aplicacióny la facilidad de su implementación de manera regular en el deporte

Active stretching and length-tension relationship of the hamstring muscles

El objetivo de este estudio fue investigar el efecto agudo de una rutina de estiramientos estático activos para la extremidad inferior, con parámetros de la carga contextualizados respecto a la realidad físico-deportiva, sobre la relación tensión-longitud excéntrica de la musculatura isquiosural. 49 deportistas recreativos completaron tres sesiones de evaluación, una inicial defamiliarización y dos experimentales (control y estiramientos). Inmediatamente después de ambos tratamientos (control y estiramientos), se valoraron los parámetros isocinéticos pico de fuerza máxima excéntrico, ángulo de fuerza máxima excéntrico y trabajo total excéntrico empleando para ello una posición de tendido prono. Si la modificación de la curva tensión-longitud excéntrica puede ser utilizada como factor de riesgo primario de distensiones de la musculatura isquiosural, los hallazgos de este estudio sugieren que el estiramiento estático activo podría no alterar el riesgo relativo de lesión de la musculatura isquiosural.The purpose of this study was to investigate the acute effect of an active lower limb stretching routine with sports-related training load on the eccentric length-tension relationship of the hamstring. 49 recreational athletes completed three assessment sessions, an initial familiarization session and two experimental sessions (control and stretching in random order). Immediately after both interventions (stretching or control), eccentric isokinetic peak torque, angle of peak torque and total work were measured in prone position. If the modification on the eccentric length-tension relationship can be used as indexes of the risk of hamstring muscle strains, the findings of the present study tentatively suggested that static stretching may not alter the relative risk of hamstring strains
