 El presente trabajo pretende evidenciar la correlación entre el nivel de pensamiento táctico de los jugadores de fútbol infantil de nivel iniciación en la mejora de las habilidades técnicas y físicas. Metodología: participaron 26 jugadores de fútbol infantil de ocho y nueve años con dos grupos: un grupo con desigualdad numérica y otro con igualdad, ambos con 13 participantes. A los dos grupos se les aplicó una batería de pruebas físicas y técnicas, así como el test del conocimiento táctico ofensivo en el fútbol (TCTOF). Los grupos estuvieron expuestos a un programa de entrenamiento de 16 sesiones. Resultados: Los jugadores pertenecientes al nivel muy bajo, solo mostraron cambios significativos negativos en la correlación flexibilidad-fuerza en piernas y pase-conducción del grupo con igualdad numérica. Los jugadores de nivel bajo mostraron cambios significativos positivos en las correlaciones de flexibilidad-fuerza en piernas, flexibilidad-cabeceo y cabeceo-fuerza en piernas. En cambio, los participantes de nivel regular (el más elevado en nuestra investigación) produjeron correlaciones significativas positivas entre golpeo de pierna no dominante-flexibilidad y este mismo golpeo con la resistencia aeróbica en el grupo con igualdad numérica. Por su parte, el grupo con igualdad numérica presentó diferencias significativas entre la fuerza-flexibilidad, velocidad-flexibilidad, pase-flexibilidad, pase-fuerza en piernas, pase-velocidad, pase-resistencia, pase-cabeceo, golpeo-regate, golpeo-conducción y golpeo con pierna no dominante-cabeceo. Conclusión: existe una correlación positiva entre el nivel de pensamiento táctico ofensivo en el fútbol con el desarrollo de las habilidades técnicas y físicas, es decir, mientras mayor sea este nivel, mayores cambios significativos se producirán en sus habilidades.  Abstract. This work aims to evidence the correlation between the level of tactical thinking of the starting level children's football players in improving technical and physical skills. Methodology: 26 eight- and nine-year-old children's football players participated with two groups: one group with numerical inequality and one with equality, both with 13 participants. The two groups were given a battery of physical and technical tests, as well as the test of tactical offensive knowledge in football (TCTOF). The groups were exposed to a 16-session training program. Results: Players at the very low level only showed changes significant negative in the correlation the flexibility and strength of the legs and pass and running of the ball in the group with numerical equality. Low-level players showed significant positive changes in correlations of flexibility and strength in legs, flexibility and heading, and heading and strength in legs. In contrast, regular-level participants (the highest in our research) produced significant positive correlations between shooting the ball with the non-dominant leg and flexibility and this same shooting the ball with the non-dominant leg with the aerobic resistance in the group with numerical equality. For its part, the group with numerical equality presented significant differences between strength and flexibility, speed and flexibility, pass the ball and flexibility, pass the ball and force in legs, pass the ball and speed, pass the ball and resistance, pass and heading the ball, shoot the ball with dominant leg and dribbling, shoot the ball with dominant leg and running with the ball, and heading the ball with shoot the ball non-dominant leg. Conclusion: there is a positive correlation between the level of tactical offensive thinking in football with the development of technical and physical skills, the higher this level, the greater significant changes in your skills.

Summary Study aim: The aim of this study is to prove that young players who have been coached with the main focus on technical ability and player interaction, perform better when tested on physical and technical attributes. Material and methods: We examined 2 separate groups made up of 15 players each. After thorough analysis, the experimental group practiced playing forms to building up 3 vs 1 games weekly for one year. The control group did not follow this training pattern. Results: Over the course of the year there was a constant development in all aspects of the examination. Furthermore, both physical and technical attributes were significantly better . The same cannot be concluded from the analysis of the control group, in which the performance level even dropped in some aspects of the examination. Conclusion: The results show that players practicing the playing forms on a weekly basis performed better in physical and technical tests. In addition, subjective experience has also underlined the effect of the method.

Background: Anterior cruciate ligament (ACL) injuries are among the most common sports-related injuries, and they can have a negative impact on players’ ability to return to play (RTP). There is a paucity of literature focused on RTP after ACL reconstruction (ACLR) in collision sports. Purpose: To characterize the impact that an ACL injury has on the ability to RTP and the post-ACLR performance level in American football players. Study Design: Systematic review; Level of evidence, 4. Methods: An electronic search was performed using the following databases: the Cochrane Database of Systematic Reviews, the Cochrane Central Register of Controlled Trials, PubMed, Embase, and the Cumulative Index to Nursing and Allied Health Literature. Included studies were written in English; were published since the year 2000; examined only American football players; and reported on RTP, performance, and/or career length after primary ACLR. Results: The initial search yielded 442 unique studies. Of these, 427 were removed after screening, leaving 15 studies that met inclusion criteria. An additional 2 studies were identified in these studies’ references, yielding a total of 17. The rate of RTP after ACLR for football players was 67.2% (1249/1859), and the mean time to return was 11.6 months (range, 35.8-55.8 weeks). Although considerable heterogeneity existed in the study design and outcomes measured, in general, a majority of football players experienced greater declines from their preinjury performance level than controls over the same time period. Conclusion: An ACL injury negatively affected football players’ ability to RTP and their post-ACLR performance. The degree of effect varied by several factors, including playing position, preinjury performance level, and National Football League Draft round. These results may be used by physicians and football players to develop reasonable expectations for returning to play and performance after an ACL injury.

The purpose of the first study was to validate two newly proposed core stability tests; Prone Plank test (PPT) and Closed Kinetic Chain test (CCT), for evaluating the strength of the body core. Subsequently, these tests were employed in a longitudinal prospective study implementing a core stability training program with a professional Spanish football team. For the validation study, 22 physically active men (Tegner Scale 6–7) performed three trials of the PPT and CCT tests in two different testing sessions separated by one week. In the longitudinal study, 13 male professional football players were equally evaluated (PPT and CCT) before and after the competitive session in which they completed a core training program. Intra-/intersession, and intertester, reliability was analyzed. PPT and CCT demonstrated excellent to good test–retest reliability and acceptable error measurement (ICCs for intratester and intrasession reliability ranged from 0.77 to 0.94 for the PPT, and 0.8–0.9 for the CCT) in all but one of the testing conditions (female tester for CCT test; ICC = 0.38). Significant improvements on core strength were found from pre to post evaluation in both the PPT (p < 0.01) and CCT (p < 0.01) after the implementation of a core training program in professional football players.

Background Optimizing training adaptations is of the utmost importance for the strength and conditioning professional. The pre-season of any sport is particularly important to ensure preparedness of the athletes. In DIII Collegiate Football pre-season consists of approximately 3 weeks. The abbreviated time of the pre-season increases the importance of optimizing training using safe methods, including alternative loading strategies. The purpose of the current study was to determine if a 3-week variable resistance training VRT during an undulating (UL) resistance training program elicited a greater increase in back squat strength compared to traditional loading methods. Methods and Materials Forty DIII Football players (age range: 18–25 years) participated in a 3-week UL bilateral back squat (BBS) program. Both groups performed the BBS 3 times per week with a minimum of 24 hours between exercise sessions. The control group (C) (n = 20) (height = 182.3 + 5.1 cm, body mass: pre = 102.8 ± 17.7 kg, post = 104.1 ± 17.8 kg) used traditional loading methods (i.e., Olympic weights only) and the experimental group (E) (n = 20) (height = 180.7 ± 8.0 cm, body mass: pre = 100.3 ± 27.1 kg, post = 101.0 ± 27.7 kg) used traditional loading methods and variable resistance (i.e., resistance bands). The variable resistance accounted for approximately 20% of the total resistance while 80% of the resistance was supplied by traditional loading methods. Results When all data was pooled, subjects had a significant increase (p < 0.05) in 1-RM BBS from pre (154.2 + 26.1 kg) to post (166.8 + 26.2 kg), with a percent increase of 8.13% at the completion of the 3-week training program. There was no significant difference (p > 0.05) between the C and E groups for muscular strength, muscular power, or vertical jump. Volume-loads were not significantly (p > 0.05) different between groups for any of the weeks (C: Week 1 = 858.1 + 101.3, Week 2 = 588.6 + 69.2, Week 3 = 332.5 + 38.9, Total = 1179.2 + 209.4 vs. E: Week 1 = 835.2 + 179.7, Week 2 = 572.2 + 123.4, Week 3 = 323.5 + 68.8, Total = 1730.9 + 371.8) or for the pre-season as a whole. Conclusion A traditional UL resistance training program and training program with variable resistance are both effective methods at increasing back squat strength during 3 weeks of training. Resistance band variable resistance (VR) does not enhance training effects within a 3-week mesocycle greater than traditional resistance.
