| 2 | British Soccer Academy Personnel Perceive Psychological and Technical/Tactical Attributes as the Most Important Contributors to Development显示文摘Purpose Understanding the desired attributes for talented soccer players may give insight into the process of(de)selection and player development.This study aimed to explore soccer academy personnel’s perceptions of attributes associated with talent and development.Methods Thirty English and Scottish academy personnel(managers,coaches,recruitment,sports scientists)provided per-ceptions into what attributes contribute to‘talent’,via an online survey.Utilising an E-Delphi method,seven experts refined these inputs over several rounds until a consensus was reached,resulting in 82 agreed terminology.This terminology was resubmitted via a second online survey,where 45 academy personnel rated each using a Likert scale.Results A ranking of attributes by importance was produced,finding Psychological and Technical/Tactical attributes con-sidered of greatest importance.Differences were observed,whereby recruitment personnel consistently over-emphasised the importance of several attributes compared to other personnel(P=0.02-0.04).When analyzed within each age phase,11 variations in the perceived importance of attributes were demonstrated in the youth phase(11-16 years,P=0.01)compared with 5 in the professional phases(17-23 years,P=0.01-0.05)Conclusion The present study demonstrates that‘talent’requires multifaceted developments,with academy personnel per-ceiving psychological attributes the most important contributor to development. | Rich J.Kite Mark R.Noon Rhys Morris Peter Mundy Neil D.Clarke | 2022 | Journal of Science in Sport and Exercise2022，4，1： | 0 |
| 3 | Does Resisted Sled Towing Improve the Physical Qualities of Elite Youth Soccer Players of Differing Maturity Status?显示文摘Purpose Sled towing has been shown to be an effective method to enhance the physical qualities in youth athletes.The aim of this study was to evaluate the impact of a 6-week sled towing intervention on muscular strength,speed and power in elite youth soccer players of differing maturity status.Method Seventy-three male elite youth soccer players aged 12-18 years(Pre-Peak Height Velocity[PHV]n = 25;Circa-PHV n = 24;Post-PHV n = 24)from one professional soccer academy participated in this study.Sprint assessments(10 m and 30 m),countermovement jump and isometric mid-thigh pull were undertaken before(T1)and after(T2)a 6-week intervention.The training intervention consisted of 6 weeks(2xper week,10 sprints over 20 m distance)of resisted sled towing(linear progression 10%-30%of body mass)during the competitive season.Bayesian regression models analysed differences between T1 and T2 within each maturity group.Results There were minimal changes in strength,speed and power(P=0.35-0.80)for each maturity group across the 6-week intervention.Where there were changes with greater certainty,they are unlikely to represent real effect due to higher regres-sion to the mean(RTM).Conclusion It appears that a 6-week sled towing training programme with loadings of 10%-30%body mass only maintains physical qualities in elite youth soccer players pre-,circa-,and post-PHV.Further research is required to determine the effectiveness of this training method in long-term athletic development programmes. | Rhys Morris Tony Myers Stacey Emmonds Dave Singleton Kevin Till | 2021 | Journal of Science in Sport and Exercise2021，3，1： | 0 |
