The aim of this study was to examine the physical performance of a success-Serie A team of more than three consecutive seasons. 25 players participated in the study and were classified into three playing positions: defenders (n=9), midfielders (n=11) and forward (n=5). Activities match were studied by an analysis of multiple match-camera SICS ® (Bassano del Grappa, Italy) throughout the competition Italian Serie A matches played at home (n=90) for 3 consecutive seasons (first: 2004/2005, second: 2005/2006, and third: 2006/2007). Total team ball possession and time-motion characteristics were examined. Results showed that total ball possession (52.1% to 54.9%) and the number of points accumulated at home (40/48) improved in the past three seasons while that the final ranking at home were stable. The total distances covered by minutes of play were significantly different between the three seasons (118.32±6.69m.min to 111.96±8.05m.min). Distance running and high intensity activities were similar in the three seasons, while the distance covered in moderate intensity running decreased in the third (P<0.05). Variations between playing positions were found during the three-consecutive seasons, with midfielders covering greater distances than defenders (P<0.05) and forward (P<0.01). This study showed how for three consecutive seasons of successful players Serie-A team reduced their distances performed at submaximal speeds, and increased ball possession, while maintaining the high-intensity activities and the number of points at home. It is suggested that this is due to a better understanding of roles and tactics team organization, and to act collectively and individually on these parameters to reduce energy expenditure during the game to maintain a high level performance throughout the season.

Most change of direction biomechanical investigations and current technique guidelines focus on the role of the final foot contact (plant foot contact). However, it is evident that the braking characteristics during the penultimate foot contact play an integral role in deceleration prior to directional changes ≥ 60˚; and can therefore, be described as a “preparatory step”. In this review, we examine the role of the penultimate foot contact on change of direction performance and associated biomechanical injury risk factors, and provide technical guidelines for coaching the “preparatory step” during change of direction, to enhance performance and reduce risk of injury.

A meta-analysis of 13 studies with a total of 18 effect sizes was performed to analyse the role of various factors on the effectiveness of flywheel paradigm training. The following inclusion criteria were employed for the analysis: (a) randomized studies; (b) high validity and reliability instruments; (c) published in a high quality peer-reviewed journal; (d) healthy participants; (e) studies where the eccentric programme were described; and (f) studies where increases in muscle volume and force were measured before and after training. Increases in muscle volume and force were noted through the use of flywheel systems during short periods of training. The increase in muscle mass appears was not influenced by the existence of eccentric overload during the exercise. The increase in force was significantly higher with the existence of eccentric overload during the exercise. The responses identified in this analysis are essential and should be considered by strength and conditioning professionals regarding the most appropriate dose response trends for flywheel paradigm systems to optimize the increase in muscle volume and force

examine existing theories and approaches that try to explain the process of skill acquisition so as to determine implications of these theories for instructional provision. This is followed by an evaluation of studies in the motor learning literature in which pre-practice information has been manipulated. Explicit learning strategies are contrasted to implicit and discovery learning methods, and current explanations for instructional eþects are discussed in terms of such mechanisms as eþects-related attentional focus and movement variability. In the ®nal sections, we review data from our own laboratory where pre-practice information has been manipulated during the learning of a novel bimanual coordination task. From these studies, proposals are made to try and explain how pre-practice information works to eþect the process of skill acquisition, including the selection and execution of a response and the processing of associated feedback. An important role is given to the existing skills of the learner in understanding the instructions and performing the desired movement. Finally, we suggest some practical implications of this empirical evidence for the teaching of motor skills.

The application of match specific constraints in resistance training for rugby players elicit different amount of variability of body acceleration across multiple physiological time scales. Understanding the non-linear process inherent to the manipulation of resistance training variables with constraints and its motor adaptations may help coaches and trainers to enhance the effectiveness of physical training and, ultimately, better understand and maximize sports performance.
- Spearritt, D. (2013). The impact of field vision on performance within an English Premier league academy soccer team: A case study.
The purpose of the current study was to develop an understanding of visual search behaviour in relation to performance outcome amongst elite level youth soccer players, within competitive match performance. Thirteen matches from an English Premier League academy soccer team (under 15 age group) were analysed using a specifically designed notational analysis system created in Microsoft Excel. Visual explorations conducted by individual players were collated, followed by their subsequent action when in possession of the ball. The results show significant visual exploration differences between higher and lower ability elite level youth players (p=0.000). The results of a series of categorical logistic regression analyses also show a clear positive relationship exists between visual exploratory behaviours that are initiated prior to a player receiving the ball and performance with the ball. This relationship remains when assessed amongst several match conditions including overall pass completion, attacking third pass completion and forward pass completion.
- Nyland, N. (2010). Visual perception in soccer: a study of elite and sub-elite defenders (Master's thesis).
The general purpose of this study was to examine how soccer defenders explore the environment for and use the information to deny opponents goals from crosses into the penalty area. A specific aim was to determine which variables differentiated between elite and sub-elite players. An ecological approach was used as conceptual framework. Participants were at the Premier League level - classified as elite (n = 13, m = 28.15 yrs, SD = 3.82) and at the Reserve League and Academy League level - classified as sub-elite (n = 11, m = 18.3 yrs, SD = 1.40). All participants were filmed in at least one game (six were filmed in two game). A high zoom camera recorded and focused solely upon a single player and general game events were obtained from professional camera recordings (obtained from the clubs) using regular zoom. These two videos were edited and synchronized into a split-screen video.
Results indicate that players in the elite group are more perceptually and functionally active than players in the sub-elite group prior to a cross, by exploring more frequently and positioning themselves more with a back-towards-goal posture allowing them to visually perceive more of the actions of the surrounding forwards. However, it was not demonstrated any functional relationship between exportation and performance related to this defensive situation. Further, constraints such as the player’s posture, type of defense, distance be-tween the crosser and defender, and involvement showed some differences between the levels and may affect exploration.
- Araújo, D., & Davids, K. (2011). What exactly is acquired during skill acquisition?. Journal of Consciousness Studies,18(3-4), 7-23.
In this paper we propose that the term skill acquisition, as commonly used in traditional psychology, and the philosophy, education, movement science and performance development literatures, has been biased by an organismic asymmetry. In cognitive and experimental psychology, for example, it refers to the establishment of an internal state or representation of an act which is believed to be acquired as a result of learning and task experience. Here we elucidate an ecological perspective which suggests that the term skill acquisition may not refer to an entity but rather to the emergence of an adaptive, functional relationship between an organism and its environment, thus avoiding an inherent organismic asymmetry in theorizing. In this respect, the terms 'skill adaptation' or 'skill attunement' might be more suitable to describe this process.

The ecological dynamics approach offers new insights to understand how athlete nervous systems are embedded within the body–environment system in sport. Cognitive neuroscience focuses on the neural bases of athlete behaviors in terms of perceptual, cognitive, and motor functions defined within specific brain structures. Here, we discuss some limitations of this traditional perspective, addressing how athletes functionally adapt perception and action to the dynamics of complex performance environments by continuously perceiving information to regulate goal-directed actions. We examine how recent neurophysiological evidence of functioning in diverse cortical and subcortical regions appears more compatible with an ecological dynamics perspective, than traditional views in cognitive neuroscience. We propose how athlete behaviors in sports may be related to the tuning of resonant mechanisms indicating that perception is a dynamic process involving the whole body of the athlete. We emphasize the important role of metastable dynamics in the brain–body–environment system facilitating continuous interactions with a landscape of affordances (opportunities for action) in a performance environment. We discuss implications of these ideas for performance preparation and practice design in sport.

The aim of the present study was to compare (a) the maximal sprinting speed (MSS) attained by soccer players during matches (MSSmatch) according to their level of play (professional first French division vs. elite amateur fourth French division) and the playing positions and (b) the MSS attained by professional soccer players during 14 different types of small-sided games (SSG, MSSSSG) and match-play. All players monitored through the study performed a 40-m sprint test to assess individual MSS (MSStest) and compare it to the training and match activity, with the calculation of the percentage of MSStest (%MSStest) reached. No differences were found according to the level of play; however, positional wide players achieved a higher MSSmatch, %MSStest, and MSSSSG than central players (both defenders and midfielders) during matches and SSG. MSSmatch were higher than all MSSSSG, and MSSSSG were positively correlated with the area of the pitch (0.45, p < 0.001), its length (0.53,p < 0.001), and the number of players involved (0.38, p < 0.001). The closer SSG was to match situation in terms of rules, the higher the MSSSSG. Wide players reached higher MSS in match and SSG than central players, confirming the relevance of using SSG close to match situation to specifically prepare elite players to the maximal running speed demand of the match.

American football is played in a chaotic visual environment filled with relevant and distracting information. We investigated the hypothesis that collegiate football players show exceptional skill at shielding their response execution from the interfering effects of distraction (interference control). The performances of 280 football players from National Collegiate Athletic Association Division I football programs were compared to age-matched controls in a variant of the Eriksen flanker task (Eriksen and Eriksen, 1974). This task quantifies the magnitude of interference produced by visual distraction on split-second response execution. Overall, football athletes and age controls showed similar mean reaction times (RTs) and accuracy rates. However, football athletes were more proficient at shielding their response execution speed from the interfering effects of distraction (i.e., smaller flanker effect costs on RT). Offensive and defensive players showed smaller interference costs compared to controls, but defensive players showed the smallest costs. All defensive positions and one offensive position showed statistically smaller interference effects when compared directly to age controls. These data reveal a clear cognitive advantage among football athletes at executing motor responses in the face of distraction, the existence and magnitude of which vary by position. Individual differences in cognitive control may have important implications for both player selection and development to improve interference control capabilities during play.
- Anson, G., Elliott, D., & Davids, K. (2005). Information processing and constraints-based views of skill acquisition: divergent or complementary?. Motor control, 9(3), 217-241.
Since the middle of the nineteenth century, movement scientists have been challenged to explain processes underlying the control, coordination, and acquisition of skill. Information processing and constraints-based approaches represent two distinct, often perceived as opposing, views of skill acquisition. The purpose of this article is to compare information processing and constraints-based approaches through the lens of Fitts’ three-stage model and Newell’s constraints-based model, respectively. In essence, both models can be identified, at least in spirit, with ideas about skill described by Bernstein (1967, 1996). Given that the product of “skill acquisition” is the same, although the explanation of the processes might differ, it is perhaps not surprising that similarities between the models appear greater than the differences. In continuing to meet the challenge to explain skill acquisition, neural-based models provide a glimpse of the cutting edge where behavior and biological mechanisms underpinning processes of control, coordination, and acquisition of skill might meet.
I’ve always enjoyed Coyle’s books, starting with the Talent Code – actually did an interview with him you can find here – https://www.building-better-athlete.com/blog/interview-with-daniel-coyle
He does a fantastic job of story telling, bring ideas together, and mixing science with culture. Some of his writings may be a little exaggerated with what the actual literature says, but its much less taken out of context as say Malcolm Gladwell.
Some of my favorite tidbits…
- In successful groups the following happens
- Everyone talks
- High expectations, and confidence that people can reach them
- Try to help things develop organically
- Leaders show vulnerability
- Surrounded with motto’s
- Leaders are partners not dictators
- They name priorities
- People feel safe and connected
Personally I find these kinds of books a little cheesy, but it’s a quick, painless read with a few tidbits here and there. Good book to throw into the mixture of more serious reads - with short chapters and some good reminders but too much of Gordon’s self-help message gets old, fast.
2-3 Gordon books a year is plenty
This was a fascinating read into 10 of the greatest psychological experiments over the past 100-years. From BF Skinner to Harry Harlow to Eric Kandel to Stanley Milgram. From topics such as love to obedience to addiction to false memories. With subjects from humans undergoing lobotomy’s, monkeys separated from their mothers and having a surrogate mother, rats being rewarded with food and drugs, sea slugs and memory.
Slater does an incredible job of blending the hard-nosed details of the experiments and outcomes, to laying out a story line of each researcher, their backgrounds into their studies, and personal stories of how these scientists affect her and other psychologists.
Give this one a read!
