Combined individual scrummaging kinetics and muscular power predict competitive team scrum success

Scrummaging is a major component of Rugby Union gameplay. Successful scrummaging is dependent on the coordination of the forward players and the strength of the eight individuals. The study aim was to determine whether individual scrummaging kinetics and other candidate factors associated with scrummaging performance discriminate team scrum performances. Sixteen club-level forwards (stature: 1.80?±?0.1?m; mass: 99.0?±?18.2?kg) were initially divided into two scrummaging packs. A total of 10 various scrum permutations were tested, where players were randomly swapped between the two packs. Winning scrums were determined by two observers on opposite sides of the scrum. Fatigue (100?mm visual analogue scale (VAS)) and scrummaging effort (6–20 rating of perceived exertion (RPE)) were assessed following each scrum contest. Individual scrummaging kinetics were acquired through an instrumented scrum ergometer and muscular power indicated through vertical jump heights. Student’s t-tests were used to differentiate between winning and losing scrum packs. VAS and RPE were assessed using repeated measures ANOVAs. Winning scrum packs had significantly larger combined force magnitudes (p?<?.002), regardless of the player contribution calculations. Additionally, winning packs had less individual movement (p?=?.033) and higher combined vertical jump heights (p?<?.001) but were not significantly heavier (p?=?.759) than losing scrum packs. While perceived VAS and RPE values progressively increased (p?<?.001), no differences in the individual scrum magnitudes were observed between the 1st and 10th scrum (p?=?.418). The results indicated that the combination of individual forces, variation in movement and factors related to scrummaging performance, such as vertical jump height, were associated with team scrummaging success.     

White Fatigue: Naming the Challenge in Moving from an Individual to a Systemic Understanding of Racism

This article introduces the notion White fatigue. White fatigue occurs for White students who have grown tired of learning and discussing race and racism, despite an understanding of the moral imperative of anti-racist and anti-oppressive practices. The article differentiates White fatigue from ideas like White resistance, White guilt, or White fragility, arguing that each of these phenomenon occur at different stages of White Racial Identity Development. Distinction is also drawn among White fatigue and other forms of racially based fatigue, specifically racial battle fatigue and White people fatigue syndrome. Further drawing on the notion of stereotype threat, the article considers the challenges for White students learning about race and racism while simultaneously resisting being labeled a racist. This struggle is elemental to the manifestation of White fatigue. Ultimately, the author argues that educators must be more accurate in how they define the range of responses from White students, consistently humanize all students in the process of understanding race and racism, and encourage further research for understanding a condition that is happening to a growing number of students.     

Factor structure evidence for developmental levels of perceptual processing on the developmental test of visual-motor integration

Beery's Developmental Test of Visual-Motor Integration was individually administered to 193 school-age children. Test protocols were factor analyzed by a principal component solution. Four factors were obtained, indicating that the test does not measure a unitary dimension of perceptual-motor development, but rather four distinct levels or stages for the age range of children investigated. The structural features of the designs that make up the test were used to define the factors. It is argued that a more useful interpretation of performance on this test would be one that designates visualmotor processing in terms of levels, not age equivalents.
