Training Design, Performance Analysis, and Talent Identification—A Systematic Review about the Most Relevant Variables through the Principal Component Analysis in Soccer, Basketball, and Rugby
Since the accelerating development of technology applied to team sports and its subsequent high amount of information available, the need for data mining leads to the use of data reduction techniques such as Principal Component Analysis (PCA). This systematic review aims to identify determinant variables in soccer, basketball and rugby using exploratory factor analysis for, training design, performance analysis and talent identification. Three electronic databases (PubMed, Web of Science, SPORTDiscus) were systematically searched and 34 studies were finally included in the qualitative synthesis. Through PCA, data sets were reduced by 75.07%, and 3.9 ± 2.53 factors were retained that explained 80 ± 0.14% of the total variance. All team sports should be analyzed or trained based on the high level of aerobic capacity combined with adequate levels of power and strength to perform repeated high-intensity actions in a very short time, which differ between team sports. Accelerations and decelerations are mainly significant in soccer, jumps and landings are crucial in basketball, and impacts are primarily identified in rugby. Besides, from these team sports, primary information about different technical/tactical variables was extracted such as (a) soccer: occupied space, ball controls, passes, and shots; (b) basketball: throws, rebounds, and turnovers; or (c) rugby: possession game pace and team formation. Regarding talent identification, both anthropometrics and some physical capacity measures are relevant in soccer and basketball. Although overall, since these variables have been identified in different investigations, further studies should perform PCA on data sets that involve variables from different dimensions (technical, tactical, conditional).
Tackle football and traumatic brain injuries : law, ethics, and public health
A timely look at the ethical, legal, and policy issues surrounding brain injury and collision sports. American tackle football is an industry like any other. And like many industries, it sells a product that is dangerous to those who use it—or, in this case, those who play it. In Tackle Football and Traumatic Brain Injuries, Daniel S. Goldberg explores the connections among traumatic brain injury, collision sports, and the industry's continuing efforts to manufacture doubt. Focusing especially on youths and adolescents—the most vulnerable population that comprises over 99% of tackle football players in the US—Goldberg addresses the ethical and social implications of their participation in tackle football. Goldberg discusses the true scope of the danger and the costs to society and individuals of caring for injured participants. If these risks were to become widespread public knowledge, the profitability and perhaps even the viability of American football would be at risk. As the tackle football industry has consistently worked to mask the health hazards involved in playing football, it has used a particular tool that has proved highly effective in achieving this subterfuge: the manufacture of doubt. Goldberg advocates for using public health laws as a tool for countering these efforts at obfuscation, and he outlines specific policy proposals intended to address the population health and ethical problems presented by tackle football. The book draws on public health ethics, public health law, and the histories of occupational and public health to assess the limits of parental choice to expose their children to risks of injury. Should kids play tackle football at all—and who decides if they should? Goldberg offers practical answers to these critical legal, ethical, and social questions. Chris Nowinski, former Harvard football player and WWE wrestler, provides a timely and insider's perspective on these critical issues in the foreword.

\"Reveals how ball games arose and took shape into seven distinct forms: American football, association football, Australian rules football, Canadian football, Gaelic football, rugby league football, and rugby union football ... [and] traces ball games back to the Mayans in Meso-America and the Han Dynasty in China, through ancient Egypt and Greece, and on through the rise of football in England and Scotland\"--Back cover.
Promoting social behavior with oxytocin in high-functioning autism spectrum disorders
Social adaptation requires specific cognitive and emotional competences. Individuals with high-functioning autism or with Asperger syndrome cannot understand or engage in social situations despite preserved intellectual abilities. Recently, it has been suggested that oxytocin, a hormone known to promote mother-infant bonds, may be implicated in the social deficit of autism. We investigated the behavioral effects of oxytocin in 13 subjects with autism. In a simulated ball game where participants interacted with fictitious partners, we found that after oxytocin inhalation, patients exhibited stronger interactions with the most socially cooperative partner and reported enhanced feelings of trust and preference. Also, during free viewing of pictures of faces, oxytocin selectively increased patients' gazing time on the socially informative region of the face, namely the eyes. Thus, under oxytocin, patients respond more strongly to others and exhibit more appropriate social behavior and affect, suggesting a therapeutic potential of oxytocin through its action on a core dimension of autism.

Interpersonal coordination analysis in bat-and-ball sports under a real game situation: Asymmetric interaction and delayed coupling
This study investigated the interpersonal coordination between the pitcher and the batter in bat-and-ball sports. Although the importance of interpersonal coordination is widely accepted in many sports, no studies have investigated it in bat-and-ball sports because the dominant task constraints surrounding the interaction between pitcher and batter make it difficult to apply conventional analytic techniques. To address the issue, this study proposes a new analytical framework to investigate interpersonal coordination in bat-and-ball sports under a real game situation with two main characteristics: asymmetric interaction and delayed coupling. First, the dynamic time warping technique was used to evaluate the stability of the head movement pattern of the pitcher and batter, and cross-correlation analysis was used to quantify the temporal relationship between them. We found that the head movement pattern of batters was significantly more unstable than that of pitchers, and approximately 60% of the variance of the change in the head movement pattern of batters could be explained by that of the pitchers. Moreover, expert batters followed a pitcher’s movements with a specific time delay of approximately 250 ms. These findings highlight the characteristics of interpersonal coordination in bat-and-ball sports: the pitcher can make a pre-patterned stable motion, whereas the batter needs to follow and adjust their movement to it. Although the effects of prediction ability need to be investigated to understand its detailed mechanism, the contribution of this study is that it revealed the existence of the interpersonal coordination between the pitcher and batter of bat-and-ball sports under a real game situation.
Motor engagement, physical activity intensity, and enjoyment in pre-school children during different game-based formats
This study aimed to compare two small and adjusted game formats (1v1 and 2v2) in basketball and soccer, focusing on preschool children’s motor engagement, physical activity (PA) levels, and self-reported enjoyment across multiple sessions. A within-subjects repeated-measures design was used, involving 26 male preschool children (5.7 ± 0.5 years old). In the basketball and soccer sessions, children played games targeting small goals (soccer) and lowered hoops represented by floor circles (basketball). During gameplay, participants wore accelerometers to measure physical activity levels, and trained observers recorded motor engagement using the Observational System for Recording Physical Activity in Children – Preschool Version (OSRAC-P). After each session, children rated their enjoyment using a validated preschool visual analog scale designed for real-time assessment of young children’s enjoyment of physical activity. Results revealed significant effects of format on light ( p  = 0.012, d = 0.53) and vigorous PA ( p  < 0.001, d = 1.25), with 2v2 promoting more light PA and 1v1 provoking more vigorous PA. Sport type significantly influenced moderate PA ( p  = 0.007, d = 0.58), with soccer showing higher values than basketball. Motor engagement differed by condition; slow-easy movements were most frequent in 2v2 soccer ( r  = 0.56), while fast movements were highest in 1v1 formats ( r  ≥ 0.52). Regarding enjoyment, 2v2 basketball consistently elicited greater scores across all dimensions—attraction ( r  = 0.59), preference ( r  = 0.63), environment ( r  = 0.69), and social engagement ( r  = 0.66)—compared to 1v1 soccer and basketball. In conclusion, the findings suggest that while more individual formats of play may support motor engagement and physical activity levels, games involving teammates and hand-based interaction may be more enjoyable for male preschoolers in short-term settings. Further studies are needed to determine whether these patterns extend to girls and to longer-term interventions.
Battle of the Brazos
During halftime of the October 30, 1926, football game between Baylor University and the Agricultural and Mechanical College of Texas, a massive riot erupted between the two student bodies that resulted in the death of Texas A&M senior cadet Charles Sessums. Though various newspaper articles have chronicled this infamous “cold case” over the last ninety years, none has placed the riot in its proper context, nor has any official determination ever identified the person responsible for Sessums’s death. T. G. Webb has pored over related historic documents, including contemporary newspaper accounts, records in the library archives of both universities, personal correspondence of the victim’s family, and the original report of the Pinkerton detective hired by Texas A&M to investigate the incident. In Battle of the Brazos , Webb examines and explains the riot, its origins, and its aftermath, untangling many enduring myths that grew up around the event over the years to establish the definitive record. He allows readers to witness the heart-breaking arrival of Cadet Sessums’s parents at the Waco train station as they came to receive the body of their deceased son, and he places readers amid the swirl of charges, recriminations, and allegations that clouded the atmosphere at both Texas A&M and Baylor. Most significantly, Webb provides previously unpublished indications of a cover-up designed to shield the killer’s identity from public knowledge. This “historical whodunit” is a must-read for sports fans and historians, devotees of “leather-helmet” football, local history buffs, and Texas football enthusiasts alike.
