A universalidade das Regras do Jogo significa que o jogo é essencialmente o mesmo em todas as partes do mundo e em todos os níveis. Bem como promover um ambiente justo e seguro para a sua prática, as Regras também devem promover a participação e a diversão. O jogo deve ser jogado e arbitrado da mesma maneira em todos os campos de futebol pelo mundo, desde a final da Copa do Mundo FIFA™ até um jogo em um vilarejo remoto. No entanto, as características locais de cada país devem determinar a duração da partida, quantas pessoas podem participar e como algumas atitudes inapropriadas devem ser punidas.

Os resultados atuais indicaram que a ocorrência de lesões de isquiotibiais podem estar associadas a uma mudança hierárquica na distribuição da atividade metabólica dentro do complexo muscular do isquiotibial após o trabalho excêntrico em que o Semitendinoso provavelmente deveria tomar a parte principal, seguido pelo BÍceps Femural e Semimembranoso. Quando o BF aumenta sua contribuição e é ativado em uma extensão proporcionalmente maior, o risco de sofrer uma lesão do isquiotibial pode aumentar substancialmente.

The purpose of this study was to investigate the acute effect of different stretching methods, during a warm-up, on the acceleration and speed of soccer players. The acceleration performance of 20 collegiate soccer players (body height: 177.25 ± 5.31 cm; body mass: 65.10 ± 5.62 kg; age: 16.85 ± 0.87 years; BMI: 20.70 ± 5.54; experience: 8.46 ± 1.49 years) was evaluated after different warm-up procedures, using 10 and 20 m tests. Subjects performed five types of a warm-up: static, dynamic, combined static + dynamic, combined dynamic + static, and no-stretching. Subjects were divided into five groups. Each group performed five different warm-up protocols in five non-consecutive days. The warm-up protocol used for each group was randomly assigned. The protocols consisted of 4 min jogging, a 1 min stretching program (except for the no-stretching protocol), and 2 min rest periods, followed by the 10 and 20 m sprint test, on the same day. The current findings showed significant differences in the 10 and 20 m tests after dynamic stretching compared with static, combined, and no-stretching protocols. There were also significant differences between the combined stretching compared with static and no-stretching protocols. We concluded that soccer players performed better with respect to acceleration and speed, after dynamic and combined stretching, as they were able to produce more force for a faster execution.

To examine the acute effects of generic (Running Drills, RD) and specific (Small- Sided Games, SSG) Long Sprint Ability (LSA) drills on internal and external load of male soccer-players. Methods: Fourteen academy-level soccer-players (mean±SD; age 17.6±0.61 years, height 1.81±0.63 m, body-mass 69.53±4.65 kg) performed four 30s LSA bouts for maintenance (work:rest, 1:2) and production (1:5) with RD and SSG drills. Players’ external- load was tracked with GPS technology (20Hz) and heart-rate (HR), blood-lactate concentrations (BLc) and rate of perceived exertion (RPE) were used to characterize players’ internal-load. Individual peak BLc was assessed with a 30s all-out test on a non-motorized treadmill (NMT). Results: Compared to SSGs the RDs had a greater effect on external-load and BLc (large and small, respectively). During SSGs players covered more distance with high-intensity decelerations (moderate-to-small). Muscular-RPE was higher (small-to-large) in RD than in SSG. The production mode exerted a moderate effect on BLc while the maintenance condition elicited higher cardiovascular effects (small-to-large). Conclusion: The results of this study showed the superiority of generic over specific drills in inducing LSA related physiological responses. In this regard production RD showed the higher post- exercise BLc. Interestingly, individual peak blood-lactate responses were found after the NMT 30s all-out test, suggesting this drill as a valid option to RD bouts. The practical physiological diversity among the generic and specific LSA drills here considered, enable fitness trainers to modulate prescription of RD and SSG drills for LSA according to training schedule.

A evidência apresentada sugere que a variação é um componente necessário do planejamento efetivo do treinamento. Apoiando essa perspectiva, outras pesquisas sugerem que a monotonia de treinamento elevado - que pode ser amplamente percebida como uma falta de variação20 - leva a uma maior incidência de síndromes de overtraining21, um mau desempenho e freqüência de infecções banais.22 Inversamente, as reduções na monotonia têm Tem sido associada a uma maior incidência de melhor desempenho pessoal 22, e os índices de monotonia têm sido defendidos como ferramentas benéficas de treinamento-regulação na elite rowing23 e no sprint24.

This paper provides a comprehensive review of the literature that has reported the monitoring of longitudinal training load and fatigue and its relationship with injury and illness. The current findings highlight disparity in the terms used to define training load, fatigue, injury and illness, as well as a lack of investigation of fatigue and training load interactions. Key stages of training and competition where the athlete is at an increased risk of injury/illness risk were identified. These included periods of training load intensification, accumulation of training load and acute change in load. Modifying training load during these periods may help reduce the potential for injury and illness.

Melhorar ou até mesmo manter o desempenho atlético em jogadores de esportes de equipe competitivos durante o longo período da temporada é um dos maiores desafios para qualquer treinador comprometido. Tempo muito limitado está disponível entre as partidas semanais para introduzir sessões intensivas de treinamento de força e poder, com uma freqüência normal de 1-2 unidades por semana. Este fato estimula a busca de métodos de treinamento mais eficientes capazes de melhorar uma ampla variedade de habilidades funcionais, evitando ao mesmo tempo os efeitos de fadiga.

Actualmente la capacidad de repetir sprints es considerada fundamental en el rendimiento del fútbol por parecerse al patrón de movimiento que se da en el mismo. De esta manera su entrenamiento resulta fundamental en cualquier planificación. Así, se deben trabajar aquellos aspectos que la limitan para poder acceder a un mayor rendimiento. Una vez conocido esto se debería elegir la forma en la que se quiere entrenar, teniendo para ello métodos analíticos (interválico, intermitente) y contextualizados (espacios reducidos). Por último, se proponen una series de variables de entrenamiento para el trabajo de repetir sprints, orientándolo no solo al aspecto físico, sino también al técnico, táctico y psicológico, conformando, por tanto, un entrenamiento integrado en el fútbol.

Current findings might help individuals involved within the physical preparation of players (e.g. technical coaches, fitness coaches, and sport science staff) when developing training programs and training sessions in line with the playing positions, and with the levels of high speed running targeted to reach during specific training drills like sided-games. Indeed, the closer to match-play situations regarding the rules with goals, goalkeepers, the larger pitch sizes and greater number of players involved, the higher sprinting speed running players would reach during sided-games. However, coaches are advised to add specific speed drills to sided-games in order to elicit a stimulus of high-speed running high enough to prepare players for competition.

In elite soccer, players are frequently required to play consecutive matches interspersed by 3 days and complete physical performance recovery may not be achieved. Incomplete recovery might result in underperformance and injury. During congested schedules, recovery strategies are therefore required to alleviate post-match fatigue, regain performance faster and reduce the risk of injury. This article is Part I of a subsequent companion review and deals with post-match fatigue mechanisms and recovery kinetics of physical performance (sprints, jumps, maximal strength and technical skills), cognitive, subjective and biochemical markers.

Sprint running acceleration is a key feature of physical performance in team sports, and recent literature shows that the ability to generate large magnitudes of horizontal ground reaction force and mechanical effectiveness of force application are paramount. We tested the hypothesis that very-heavy loaded sled sprint training would induce an improvement in horizontal force production, via an increased effectiveness of application. Training-induced changes in sprint performance and mechanical outputs were computed using a field method based on velocity- time data, before and after an 8-week protocol (16 sessions of 10x20-m sprints). 16 male amateur soccer players were assigned to either a very-heavy sled (80% body-mass sled load) or a control group (unresisted sprints). The main outcome of this pilot study is that very-heavy sled resisted sprint training, using much greater loads than traditionally recommended, clearly increased maximal horizontal force production compared to standard unloaded sprint training (effect size of 0.80 vs 0.20 for controls, unclear between-group difference) and mechanical effectiveness (i.e. more horizontally applied force; effect size of 0.95 vs -0.11, moderate between-group difference)

Hip extension and Nordic hamstring exercise training both promote the elongation of biceps femoris long head fascicles, and stimulate improvements in eccentric knee flexor strength.  Hip extension training promotes more hypertrophy in the biceps femoris long head and semimembranosus than the Nordic hamstring exercise, which preferentially develops the semitendinosus and the short head of biceps femoris

No sentido de melhor esclarecer esta forma de operacionalizar o processo de treino procuramos num primeiro momento sistematizar os aspectos conceptometodológicos que a definem. Contudo, a “Periodização Táctica” é uma concepção que se encontra pouco retratada na literatura e por isso, deparamo-nos com escassas referências bibliográficas levando-nos a reequacionar o teor deste trabalho. Neste seguimento, decidimos incidir nos fundamentos conceptometodológicos que a definem, a partir de dados empíricos do processo de treino-competição do treinador José Guilherme Oliveira . A escolha deste treinador deve-se ao facto de ser reconhecido pelo professor Vítor Frade como um dos treinadores que operacionaliza o processo de treino tendo em conta as premissas da “Periodização Táctica”.

The architectural and morphological adaptations of the hamstrings in response to training 33 with different exercises have not been explored. PURPOSE: To evaluate changes in biceps 34 femoris long head (BFLH) fascicle length and hamstring muscle size following 10-weeks of 35 Nordic hamstring exercise (NHE) or hip extension (HE) training. METHODS: Thirty 36 recreationally active male athletes (age, 22.0 ± 3.6 years, height, 180.4 ± 7 cm, weight, 80.8 ± 37 11.1 kg) were allocated to one of three groups: 1) HE training (n=10), NHE training (n=10), 38 or no training (CON) (n=10). BFLH fascicle length was assessed before, during (Week 5) and 39 after the intervention with 2D-ultrasound. Hamstring muscle size was determined before and 40 after training via magnetic resonance imaging.

Small-sided games (SSGs) have been extensively used in training footballers worldwide and have shown very good efficacy in improving player performance (Hill-Haas, Dawson, Impellizzeri, & Coutts, 2011). As an example, it has been shown that the technical performance (Owen, Wong del, McKenna, & Dellal, 2011) and physical performance (Chaouachi et al., 2014; Dellal, Varliette, Owen, Chirico, & Pialoux, 2012) of footballers can be enhanced using SSG-based football training programmes. In the last two decades, extensive research has been pub- lished on physical and physiological response during SSGs in football (for refs, see Halouani, Chtourou, Gabbett, Chaouachi, & Chamari, 2014). It was found that the time-motion charac- teristics of SSGs could vary greatly depending on certain structural (e.g., pitch size, number of players, type and number of goals) and rule (e.g., number of ball touches) constraints. For example, it was observed that higher maximum speeds are reached during SSGs played on bigger pitches (Casamichana & Castellano, 2010). Furthermore, heart rate (HR) and lactate concentrations were shown to be sensitive to structural and rule changes in SSGs.

Results from the present study quantify the effects of altering either the intensity of the work or the recovery interval when performing interval sessions consisting of 60s of work and 60s of recovery for multiple repetitions. The information provided may aid those interested in designing interval training sessions by providing ranges of values that could be expected for individuals who possess moderate levels of cardiopulmonary fitness. Using a work intensity of 80% or 100% VGO2peak and a recovery intensity of 0% or 50% VGO2peak, subjects were able to exercise within the ACSM recommended range for exercise intensity. Based upon the data it would appear that a protocol such as the 80/0 may be appropriate for those individuals who are just beginning a program or have little experience with interval-type activity. By contrast, a 100/50 protocol could not be completed by all of the subjects and therefore may be too intense for some individuals.

The quadriceps femoris is traditionally described as a muscle group com- posed of the rectus femoris and the three vasti. However, clinical experience and investigations of anatomical specimens are not consistent with the text- book description. We have found a second tensor-like muscle between the vastus lateralis (VL) and the vastus intermedius (VI), hereafter named the tensor VI (TVI). The aim of this study was to clarify whether this intervening muscle was a variation of the VL or the VI, or a separate head of the exten- sor apparatus. Twenty-six cadaveric lower limbs were investigated...
