Los objetivos de este estudio fueron, por un lado, evaluar la capacidad cardiovascular, el rendimiento en el sprint en línea recta, la capacidad de cambio de dirección (CODA) y el salto horizontal en jugadores de fútbol semi profesionales, y por otro, examinar la relación existente entre las distintas capacidades analizadas. En este estudio participaron 18 jugadores de fútbol semi profesionales (25.6 ± 4.8 años, 1.82 ± .1 m, 77.9 ± 7.1 kg, 23.6 ± 1.8 kg·m-2). El VO2max estimado obtenido en el test intermitente de resistencia Yo-Yo nivel 1 (YYIR1) fue de 51.70 ± 3.94 ml·kg-1·min-1. Los resultados en el sprint 5 m (SP5), 15 m (SP15) y en el Modified Agility T-test (MAT) fueron de 1.01 ± .05 s, 2.39 ± .10 s y 4.89 ± .23 s, respectivamente. En la capacidad de salto horizontal (SH) se obtuvo una distancia media de 1.97 ± .15 m para el salto con contra movimiento (HCMJ) y de 2.37 ± .16 m para el salto con contra movimiento con manos libres (HCMJAS). Se observaron correlaciones significativas y altas entre los valores de SP15 con el MAT (r = .757, p < .01) y con el HCMJ (r = -.749, p < .01). Debido a las altas correlaciones encontradas entre las distintas cualidades anaeróbicas, podría resultar interesante implementar entrenamientos específicos de salto horizontal en las rutinas de entrenamiento con el fin de mejorar el rendimiento en la capacidad de aceleración y la capacidad de cambiar de dirección de los futbolistas. Palabras clave: aceleración, agilidad, salto horizontal, resistencia, correlación, rendimiento.Abstract: The aims of this study were, first, to analyze cardiovascular capacity, performance in the straight sprint, change of direction ability (CODA) and horizontal jump ability in semi-professional soccer players, and secondly, to examine the relationship among the different abilities. This study involved 18 semi professional soccer players (25.6 ± 4.8 years, 1.82 ± .1 m, 77.9 ± 7.1 kg, 23.6 ± 1.8 kg·m-2). The estimated VO2max obtained in the Yo-Yo intermittent endurance level 1 test (YYIR1) was 51.70 ± 3.94 ml·kg-1·min-1. The results in the 5 m sprint (SP5), 15 m sprint (SP15) and Modified Agility T-test (MAT) were 1.01 ± .05 s, 2.39 ± .10 s and 4.89 ± .23 s, respectively. In the horizontal jump (HJ) an average distance of 1.97 ± .15 m for the countermovement jump (HCMJ) and 2.37 ± .16 m for the arm swing counter movement jump (HCMJAS) was obtained. Significant and high correlations between the values   of SP15 and MAT (r = 0.757, p < .01) and the HCMJ (r = -.749, p < .01) were observed. Correlations found among different anaerobic qualities, can lead us to think that it might be interesting to implement specific horizontal jump training routines to improve performance of sprint and change of direction abilities in soccer players.Key words: acceleration, agility, horizontal jump, endurance, correlation, performance.

The Difference

Purpose: To investigate the difference between straight-line (STL) and change-of-direction (COD) intermittent-running exercises in soccer players. Methods: Seventeen male professional soccer players performed the agility T test and 6 intermittent-running exercises: 10 s at 130% of maximal aerobic speed (MAS) alternated with 10 s of rest (10-10), 15 s at 120% of MAS alternated with 15 s of rest (15-15), and 30 s at 110% of MAS alternated with 30 s of rest (30-30) both in STL and with COD. All exercises were monitored using a global positioning system. Heart rate was measured during exercises, and rating of perceived exertion (RPE) was collected postexercise. The difference (Δ) between covered distance in STL and COD exercises at a similar load was calculated, and relationships between T test and Δ distance were analyzed. Results: COD intermittent exercises showed a significantly decreased distance covered and an increase in the number of accelerations, peak heart rate, and RPE compared with STL intermittent exercises at a similar load. High relationships were observed between T-test performance and Δ distance in 10-10 (r = .72, P < .01) and 15-15 (r = .77, P < .01), whereas no significant relationships were observed between T-test performance and Δ distance in 30-30 (r = −.37, P = .2). Conclusion: Intermittent COD exercises were associated with higher acceleration, peak heart rate, and RPE than STL during 10-10 and 15-15 exercises. The ability to rapidly change direction is crucial to perform intense sport-specific running in professional soccer players.

Although asymmetries in lower limbs have been linked with players’ performance in male soccer players, literature that has been published addressing female soccer is scarce. Thus, the aim of this study was twofold: (i) describe the asymmetries of women soccer players during jumping, change-of-direction and range-of-motion tests; and (ii) test possible relationships between asymmetries and injury risk in female soccer players. Sixteen female players (15.5 ± 1.5 years) performed a battery of fitness tests (i.e., jump ability, change-of-direction ability and passive range-of-motion) and muscle mass analysis via dual-energy X-ray absorptiometry, through which the specific asymmetry index and the related injury risk were calculated. Significant (p < 0.05) lower asymmetries in the change-of-direction test were observed in comparison to those observed in jumping and range-of-motion tests; significant (p < 0.05) lower asymmetries in muscle mass were also reported compared to those found in the change-of-direction and countermovement jump tests. Additionally, increased injury risk for countermovement jump and hip flexion with extended knee range-of-motion (relating to asymmetry values) and for ankle flexion with flexed knee range-of-motion in both legs (relating to reference range-of-motion values), as well as increased individual injury risk values, were observed across all tests. These findings suggest the necessity to implement individual approaches for asymmetry and injury risk analyses.

El fútbol es un deporte colectivo donde, para alcanzar el éxito, los jugadores necesitan de habilidades técnicas, tácticas y físicas, fundamentalmente de carácter intermitente siendo éstas acciones las que determinan el rendimiento. Un ejemplo de acciones de este tipo son los saltos. Este gesto deportivo esta correlacionado con la fuerza máxima, entendiendo que una mayor producción de fuerza permite una mayor generación de altura en dicho gesto. El objetivo de este trabajo es estudiar el efecto de entrenamiento de fuerza en sistema isoinercial sobre la mejora del Salto con Contramovimiento y analizar los cambios en la altura del mismo después de un programa de entrenamiento de 15 semanas, realizado sobre jóvenes futbolistas de élite. Los resultados obtenidos, muestran que no existen cambios significativos en esta variable de análisis (p< 0,05) por lo que se concluye que este tipo de entrenamiento con la duración especificada no tiene efectos sobre el rendimiento en la altura del salto (CMJ).Palabras clave: Entrenamiento Isoinercial, Futbolistas, Rendimiento, CMJ.Abstract: Soccer is a team sport where, to achieve success, players need of technical, tactical and physical skills, mainly intermittent character being such actions which determine the performance. An example of such actions is the jumpers. This sports actions is correlated with the maximal strength, understanding that force production allows greater height in this actions. The aim is to study the effects of strength training using a isoinertial device on Countermovement Jump ability and to analyze the changes in height after 15 weeks program training in young elite soccer players. There are no significant changes after to analyze the results (p< 0,05), so it is concluded that this type of training with certified duration has no effect on performance in height jump (CMJ).Keywords: Isoinertial Training, Soccers Players, Performance, CMJ.

Purpose: Resisted sled sprinting (RSS) is an effective tool for improving sprint performance over short distances, but the effect on change-of-direction (COD) performance is largely unknown. The present study investigated the effect of heavy RSS training during the competitive season on sprint and COD performance in professional soccer players. Methods: Over 6 wk in-season, an RSS training group (n = 6) performed RSS at a sled load of 30% body mass for a total program running distance of 800 m, whereas an unresisted sprint (URS) training group (n = 7) performed the same distance of unresisted sprinting. A 20-m maximal sprint with split times measured at 5, 10, and 20 m and the sprint 9-3-6-3-9 m with 180° turns COD test were performed before and after the intervention. Results: Sprint performance (mean, 95% confidence limits, qualitative inference) was improved in both groups over 5 m (URS, 5.1%, −2.4 to 12.7, likely moderate; RSS, 5.4%, 0.5–10.4, likely moderate), 10 m (URS, 3.9%, −0.3 to 8.1, very likely moderate; RSS, 5.0%, 1.8–8.0, very likely large), and 20 m (URS, 2.0%, −0.6 to 4.5, likely moderate; RSS, 3.0%, 1.7–4.4, very likely moderate). COD was improved in both groups (URS, 3.7%, 2.2–5.2, most likely large; RSS, 3.3%, 1.6–5.0, most likely moderate). Between-groups differences were unclear. Conclusion: Heavy RSS and URS training matched for running distance were similarly effective at improving sprint and COD performance in professional soccer players when performed in the competitive phase of the season.

Aim: Increased hamstring and lower back flexibility may contribute to preventing muscle injuries. However, inconsistencies exist on whether dynamic or static stretching exercises should be routinely used prior to and after training sessions/games to improve performance and ameliorate muscle soreness. No studies so far evaluated whether “poor” or “good” levels of flexibility may influence fitness parameters in elite young soccer players. The purpose, therefore, of the present study was to examine the effect of lower back and hamstring flexibility on several fitness parameters in elite young soccer players. Material & Method: One hundred three young elite soccer players (U15, U17, U19 National team members) were initially evaluated, but only 81 met the cut-off criteria and were included in the statistical analysis. These 81 players were separated into two groups based on their sit-and-reach flexibility score. The players whose score was less than 22 cm were included in the low-flexibility (L-Flex) group (n = 52), and those whose reach score was above 28 cm were included in the high-flexibility (H-Flex) group (n = 29). A comparison of several fitness parameters between groups was performed using unpaired t test. Results: Sit-and-reach flexibility was significantly higher (p < 0.001) in H-Flex (31.5 ± 3 cm) compared with the L-Flex group (18 ± 5 cm). No differences between groups were observed in age, height, body weight, % body fat, maximum speeds (5–30 m), isokinetic parameters, maximum aerobic speed and VO2max (p > 0.05). Countermovement jump (CMJ, p = 0.023) and CMJ with arm-swing (p = 0.005) were significantly better in the H-Flex compared with the L-Flex group. No correlation was observed between mean flexibility score and any other evaluated fitness parameters (p > 0.05). Conclusions: High level of sit-and-reach flexibility may contribute to enhancing neuromuscular explosiveness performance in young elite soccer players. However, the exact mechanism responsible for these results still need to be determined.

 Abstract: The aim of the study was to compare the players characteristics and physical fitness parameters according to playing positions and to identify the relation between body composition and physical fitness in professional soccer players at the beginning of the preparation period. Sixteen professional soccer players participated in this study. Body composition was evaluated by air displacement plethysmography instrumentation (BOD POD®) and physical fitness with specific tests: Running Anaerobic Sprint Test (RAST), Counter Moviment Jump (CMJ), Squat Jump (SJ) and Abalakov jump (ABK), Yo-yo Intermittent Recovery Level 1 (Yo-yo IR1), agility test and flexibility. Kruskal Wallis test demonstrated no significant difference in all estimated body composition, age, height and physical fitness parameters according to three playing positions (p < 0.05). We verified a significant negative correlation between body fat percentage and the performance of CMJ, SJ, ABK, peak, mean and minimum power (-.51 to -.87) and a significant positive correlation with the agility parameter (r = .85). Regarding to lean mass percentage, a significant positive correlation was found with performance of CMJ, SJ, ABK and peak, mean and minimum power (.51 to -.82) and significant negative correlation with agility parameter (r = -.85). Based on the results, we concluded that at the beginning of a pre-season a higher body fat percentage is associated with a negative influence in physical fitness, thus confirming that a greater amount of lean mass percentage is positively associated with the initial level of physical fitness of professional soccer players. Resumén: El objetivo del studio fue comparar las características de los jugadores y los parâmetros de aptitud física según las posiciones de juego e identificar la relación entre la composición corporal y la aptitud física em futebolistas profisionales al inicio del período de preparación. Dieciséis futebolistas profesionales participaron em este estudio. La composición corporal se evaluómediante instrumentación de plestimografia por desplazamiento de aire (BOD POD®) y aptitud física com pruebas específicas: capacidade anaeróbia (RAST), saltos verticales (CMJ, SJ y salto abalakov- ABK), resistência aeróbia, prueba de agilidade y flexibilidad. Kruskal Wallis no demostró diferencias significativas em todos los parâmetros estimados de composición corporal, edad, altura y condición física según las três posiciones de juego (p < 0.05). Verificamos uma correlación negativa significativa entre el porcentaje de grasa corporal y el rendimento de CMJ, SJ, ABK, potencia pico, media y mínima (-.51 to -.87) y uma correlación positiva significativa com el parâmetro de agilidade (r = .85). Em cuanto al porcentaje de massa magra, se encontro uma correlación positiva significativa com el rendimento de CMJ, SJ, ABK y potencia pico, media y mínima (.51 to -.82) y correlación negativa significativa com el parâmetro de agilidade (r = -.85). Com base em los resultados, concluimos que al inicio de una pré-temporada um mayor porcentaje de grassa corporal se associa com uma influencia negativa em la aptitud física, confirmando así que uma mayor porcentaje de massa magra se associa positivamente com el nível inicial de aptitud física de los futebolistas profesionales.

Abstract This study aimed to compare the width, the length, the length per width ratio, and the stretch index between the first and the second halves in official soccer matches, and to compare the spatial exploration index between players from different positions. Seventeen professional soccer players from a Brazilian club participated in the study and were monitored during six official matches by a GPS device. Collective positional data were compared between the two halves using a paired t-test, while the spatial exploration index was compared between the playing positions and within the halves by a mixed two-way ANOVA. The results revealed no differences between the two halves for the collective variables. The highest values of spatial exploration index were reported for central midfielders and wing forwards. We conclude that the tactical behavior of professional soccer players is position-dependent, and midfielders are the most exploratory players on the pitch.

The aim of the present study was to compare the fitness profiles and internal training loads between senior team and academy team soccer players during an in-season phase. Twenty-two professional soccer players from the senior team (n=12; 28.3<img width="12" alt="" height="20"> 2.0 years) and under 19 (U19) team (n=10; 18.0<img width="12" alt="" height="20"> 0.4 years) of the same club participated in the present study. High-intensity running performance, acceleration, maximal sprint, and change of direction (COD) ability were all tested during the mid-season break of a competitive season. Session rating of perceived exertion (sRPE) reflecting the internal training load during the entire first half of the season was being documented daily. Senior players showed small to moderate superiority in COD (1.8%, 90% confidence intervals [CI, -3.2; 7.1], ES: 0.24 [-0.44; 0.92]), maximal sprint (2.3%, [0.0; 4.7], ES: 0.81 [0.00; 1.63]) and acceleration (3%, [0.2; 5.8], ES: 0.96 [0.06; 1.85]). The U19 showed small better high-intensity intermittent running fitness (2.5%, [-1.2; 6.3], ES: 0.39 [-0.20; 0.97]). When analyzing internal training loads (from M-3 to M+3), the U19 showed small to very large higher sRPE values for all days (range; 8.2%; 229.3%, [-8.1; 328.3], ES range; 0.25; 2.70, [-0.26; 3.3]), except for match days (M), on which unclear trivial difference was observed (-1.5%, [-9.6; 7.5], ES -0.09 [-0.65; 0.46]). Our results showed that senior players and youth players had different fitness profiles and internal training loads during the first half of a competitive season; this should be taken into consideration when designing specific and individualized recovery and training sessions.
