Sport selection in under-17 male roller hockey

Abstract

Characteristics of 32 international and 41 local under-17 (U-17) (14.5–16.5 years) roller hockey players were considered in the context of discrimination by competitive level using training history, anthropometry, skeletal maturation, and several laboratory and field performance tests. More international (42%) than local (22%) players were advanced in maturity status. International players had slightly less hockey experience (years), but had more practice sessions and match time (minutes) during the season. Local players were shorter and attained better performance in the 25-m dash, while international players performed better in sit-ups, ball throw and 20-m shuttle run. The fatigue index derived from the Wingate anaerobic test was higher among local players, while peak torques of knee extension and flexion were greater in international players. Stepwise discriminant function correctly classified 85% of players by competitive level based on grip strength, ratio of eccentric and concentric knee extension, number of training sessions, playing time and fatigue index. The results suggested an interaction among strength, anaerobic fitness and training plus game time as factors in discriminating international from local level players and by inference in the selection and development of youth roller hockey players.     

FACILITATORS OF AND BARRIERS TO MODEL SCHOOL PSYCHOLOGICAL SERVICES

This study examined facilitators of and barriers to comprehensive and integrated services. A national sample of 267 full‐time practicing school psychologists who were Regular Members or Early Career Members of the National Association of School Psychologists participated. We administered a survey to participants that measured the extent to which they engaged in comprehensive and integrated services and the top facilitators of and barriers to those services using web‐based survey procedures. Results indicated that the majority of facilitators identified (Personal Attributes, Stakeholder Involvement, Resources and Support, School‐Specific Variables, Contextual Variables) predicted greater levels of comprehensive and integrated service delivery. Identified barriers—which often reflected the opposite condition of the facilitators—predicted lower levels of service delivery in some instances; however, they predicted services less often than did facilitators. Implications for research focused on better understanding factors that impact service delivery and on processes for facilitating increased comprehensive and integrated service delivery are discussed. Additionally, implications for practice include the assessment of facilitators and barriers, the use of data to plan for the delivery of comprehensive and integrated services, and advocacy for systems change.
