This study investigated the associations between fundamental athletic movement and physical fitness in junior Australian football (AF). Forty-four under 18 players performed a fundamental athletic movement assessment consisting of an overhead squat, double lunge, single leg Romanian deadlift and a push up. Movements were scored on three assessment criterions using a three-point scale. Additionally, participants performed five physical fitness tests commonly used for talent identification in AF. A Spearman’s nonparametric correlation matrix was built, with correlation coefficients being visualised using a circularly rendered correlogram. Score on the overhead squat was moderately positively associated with dynamic vertical jump height on left (r_s = 0.40; P ≤ 0.05) and right (r_s = 0.30; P ≤ 0.05) leg take-off, stationary vertical jump (r_s = 0.32; P ≤ 0.05) and negatively associated with 20-m sprint time (r_s = ?0.35; P ≤ 0.05). Score on the double lunge (left/right side) was moderately positively associated with the same physical fitness tests as well as score on the multistage fitness test. Results suggest that improvements in physical fitness qualities may occur through concurrent increases in fundamental athletic movement skill, namely the overhead squat and double lunge movements. These findings may assist with the identification and development of talent.  相似文献

Abstract

Differences in physiological, physical, and technical demands of small-sided basketball games related to the number of players, court size, and work-to-rest ratios are not well characterised. A controlled trial was conducted to compare the influence of number of players (2v2/4v4), court size (half/full court) and work-to-rest ratios (4x2.5 min/2x5 min) on the demands of small-sided games. Sixteen elite male and female junior players (aged 15–19 years) completed eight variations of a small-sided game in randomised order over a six-week period. Heart rate responses and rating of perceived exertion (RPE) were measured to assess the physiological load. Movement patterns and technical elements were assessed by video analysis. There were ～60% more technical elements in 2v2 and ～20% more in half court games. Heart rate (86 ± 4% & 83 ± 5% of maximum; mean ± SD) and RPE (8 ± 2 & 6 ± 2; scale 1–10) were moderately higher in 2v2 than 4v4 small-sided games, respectively. The 2v2 format elicited substantially more sprints (36 ±12%; mean ±90% confidence limits) and high intensity shuffling (75 ±17%) than 4v4. Full court games required substantially more jogging (9 ±6%) compared to half court games. Fewer players in small-sided basketball games substantially increases the technical, physiological and physical demands.  相似文献   

Gold Medal Volleyball: The Training Program and Physiological Profile of the 1984 Olympic Champions     

Carl M. McGown  Robert K. Conlee  Anthony A. Sucec  Michael J. Buono    William Phillips 《Research quarterly for exercise and sport》2013,84(2):196-200

Abstract

This study focused on the differences between experienced and inexperienced physical education teachers' approaches to planning, low inference indicators of teaching behavior during instruction, and global variables from the Beginning Teacher Evaluation Study. It was found experienced teachers asked many more questions before they began planning than did inexperienced teachers. Experienced teachers' plans reflected a concern about contingencies that might arise during instruction, whereas inexperienced teachers' plans did not. Interaction analysis and codings of student engagement showed marked differences between experienced and inexperienced teachers. Judging the qualities of experienced and inexperienced teachers also showed important differences. These sources of data are interrelated and give a vivid picture of how experienced and inexperienced teachers differ in accomplishment of instruction. The findings are discussed in terms of what they may mean for teacher development programs.  相似文献

A Comparison of Knowledge Obsolescence of Graduating Seniors and Practitioners in the Field of Physical Education     

E. James Kelley  Carl A. Lindsay 《Research quarterly for exercise and sport》2013,84(4):636-644

Abstract

The issue of defining and measuring professional obsolescence among physical educators is examined through a comparison of the current knowledge base of graduating physical education seniors and physical education practitioners in Pennsylvania. In a previous study, the “Inventory of Recent Knowledge in Physical Education,” a 260-item sample of current knowledge as defined by content experts was developed by the authors and administered by mail to the population of 2,737 male professional members of the public school districts' departments of physical education in Pennsylvania. In the present study, results from the first study were compared with those from an administration of the same instrument to 462 female and male physical education majors graduating from nine Pennsylvania higher education institutions. Both studies employed multiple-matrix procedures for item-person sampling and data analysis. An analysis of the results for both groups showed essentially similar performance profiles on the Inventory. Average scores of the two groups tended to be low and neither met preestablished minimum standards for defining up-to-date or nonobsolete performance. These results point to a clear conflict between what experts think up-to-date persons in the field of physical education should know and the knowledge performance of practitioners and students.  相似文献   

Grip and Forearm Position Effects on Tests of Static and Dynamic Upper Body Endurance     

Carl Gabbard  Patrick Patterson  Jerry Elledge 《Research quarterly for exercise and sport》2013,84(2):174-179

Abstract

The effects of grip and forearm position on two tests of upper body muscular endurance were investigated in 109 male subjects 18–21 years of age. Subjects were systematically presented 12 tasks: six pull-up and six straight-arm hang grip and forearm variations. Each of the six tasks for both endurance tests represented a different combination of grip (thumb over bar and thumb under bar) and forearm position (pronated, supinated and semi-pronated). Task results were analyzed utilizing 2 × 3 (grip × forearm) ANOVA with repeated measures on the two factors. Analysis of pull-up data revealed that the semi-pronated and supinated forearm positions were not statistically different from each other, but superior to the pronated condition. Results of straight-arm hang performance revealed a significant difference between grips at the semi-pronated position, with the “thumb under bar” being superior. Results for forearm positions at grips indicated a significant difference for the “thumb under bar,” with the pronated and semi-pronated positions being superior to the supinated position. For forearm positions at “thumb over bar,” the pronated condition was significantly different from the semi-pronated and supinated positions. Thumb position trends and kinesiological mechanical analysis did foster general recommendations for use of the “thumb over bar” for pull-ups and the “thumb under bar” position for the straight-arm hang.  相似文献   

Addressing the Sex Abuse Crisis in Communities of Faith and Learning     

Carl Procario-Foley 《Religious education (Chicago, Ill.)》2020,115(3):335-342

Abstract

This paper argues that educational communities of faith and learning (e.g. Catholic colleges and universities) are especially primed to face into the pain and reality of the sex abuse crisis in honest and constructive ways. Citing the need for strategic collaboration between mental health professionals and religious educators, it calls for pedagogies which: are trauma-informed and utilize the insights of neuroscience; promote open dialogue in the face of organizational silence; foster safe and courageous spaces; attend to the dangerous memory and deep impacts which accompany survivors of the sex abuse. It argues that failure to address the sex abuse crisis with open and interdisciplinary discourse fosters a null curriculum that will only serve to have corrosive implications.  相似文献
