The European dilemma: evaluating the implications of UEFA Europa League participation on English Premier League clubs     

Adam Cox  Sarah Gilmore 《Soccer & Society》2017,18(7):817-835

For clubs qualifying for the UEFA Europa League, participation generates a series of tensions. UEFA has provided financial rewards for those clubs, but with qualification comes additional pressures on playing squads which are often less able to deal with the performative demands of an extra competition, as they generally possess fewer financial resources compared with teams gaining Champions League qualification. This paper evaluates these conflicting tensions. The study takes a detailed quantitative analysis of the costs and benefits for four Premier League clubs that have repeatedly participated in the Europa League over eight seasons. It demonstrates a positive financial benefit of participation, but this is only significant if the club progresses to the later competition stages and has a robust playing squad. This research fills a gap in a lack of analysis based on reliable empirical data as to the impact of participation in this competition on clubs.  相似文献   

Redistributing load using wearable resistance during power clean training improves athletic performance     

Caleb R. Marriner  John B. Cronin  Adam Storey 《European Journal of Sport Science》2017,17(9):1101-1109

A popular method to improve athletic performance and lower body power is to train with wearable resistance (WR), for example, weighted vests. However, it is currently unknown what training effect this loading method has on full-body explosive movements such as the power clean. The purpose of this study was to determine what effects WR equivalent to 12% body mass (BM) had on the power clean and countermovement jump (CMJ) performance. Sixteen male subjects (age: 23.2?±?2.7 years; BM: 90.5?±?10.3?kg) were randomly assigned to five weeks of traditional (TR) power clean training or training with 12% BM redistributed from the bar to the body using WR. Variables of interest included pre and post CMJ height, power clean one repetition maximum (1RM), peak ground reaction force, power output (PO), and several bar path kinematic variables across loads at 50%, 70%, and 90% of 1RM. The main findings were that WR training: (1) increased CMJ height (8.7%; ES?=?0.53) and 1RM power clean (4.2%; ES?=?0.2) as compared to the TR group (CMJ height?=??1.4%; 1RM power clean?=?1.8%); (2) increased PO across all 1RM loads (ES?=?0.33–0.62); (3) increased barbell velocity at 90% 1RM (3.5%; ES?=?0.74) as compared to the TR group (?4.3%); and (4) several bar path kinematic variables improved at 70% and 90% 1RM loads. WR power clean training with 12% BM can positively influence power clean ability and CMJ performance, as well as improve technique factors.  相似文献   

Changes in Cardiorespiratory Responses and Kinematics With Hippotherapy in Youth With and Without Cerebral Palsy     

Brandon Rhett Rigby  Adam Robert Gloeckner  Suzanne Sessums  Beth Anne Lanning 《Research quarterly for exercise and sport》2017,88(1):26-35

Purpose: The purpose of this study was to characterize pelvic displacement and cardiorespiratory responses to simulated horseback riding and walking in youth with cerebral palsy and to compare responses to youth without cerebral palsy before and after 8 weeks of hippotherapy. Method: Eight youth with cerebral palsy (M_age = 10 ± 4 years; M_height = 137 ± 24 cm; M_weight = 32 ± 16 kg) and 8 youth without cerebral palsy (M_age = 11 ± 2 years; M_height = 149 ± 14 cm; M_weight = 48 ± 15 kg) underwent a hippotherapy intervention. Participants completed simulated horseback riding at an intensity approximating a fast walk (0.65 Hz) and walked on a treadmill (1 mph, 0% grade) before and after hippotherapy. Pelvic displacement along the anterior-posterior, vertical, and medial-lateral axes, heart rate, oxygen consumption, ventilation, and blood pressure were measured at rest and during steady-state exercise in both exercise modes. Results: Kinematics and cardiorespiratory responses were similar between the 2 groups during simulated horseback riding (p > .05 for all) before the intervention. Significantly greater cardiorespiratory responses were observed in the youth with cerebral palsy compared with the group without cerebral palsy while walking before and after the intervention (p < .05, effect sizes 26% to 237% greater). Eight weeks of hippotherapy did not alter responses, but anecdotal improvements in gait, balance, posture, and range of motion were observed in those with cerebral palsy. Conclusion: These results contribute to our understanding regarding the efficacy of hippotherapy as an intervention to improve functional abilities in those with cerebral palsy.  相似文献   

Hyperactive children's perceptions of teachers' classroom behavior     

Dennis Peter  John Allan  Adam Horvath 《Psychology in the schools》1983,20(2):234-240

The relationship between hyperactive behavior and children's perceptions of teachers' behavior was investigated. Particular attention was paid to two aspects of teacher behavior—acceptance and demand. An extensive literature review supported the position of viewing hyperactive behavior from a situational and an interactional perspective. The literature also indicated that children's behavior is affected by their perceptions of adult behavior. The subjects were 92 boys enrolled in 8 regular elementary school classrooms. Children's perceptions of acceptance and demand in their teacher's behavior were measured by administering a partial form of the Teacher Behavior Questionnaire to classroom groups. Observed levels of hyperactive behavior were measured by having the subjects' teachers complete the Conners Abbreviated Questionnaire for each boy. Using correlational analyses, hyperactive behavior was found to be significantly related to both variables in the directions of less perceived acceptance and greater perceived demand. The combination of these two measures accounted for 16% of the variance between hyperactivity and student perception of teacher behavior. On group comparison measures, hyperactive boys perceived significantly less acceptance and greater demand than did their nonhyperactive peers.  相似文献
