Two scores were derived from LSPT: 1) execution time: time complete 16 passes (speed) 2) skill performance including bonus penalty for accuracy. consisted 2 parts, first which incorporated a quasi-longitudinal design with 270 aged 10-18 years performing LSPT (661 measurement occasions); multilevel modelling...
Talent development programmes for professional soccer clubs aim to guide players towards level performance. We identify whether the intermittent endurance capacity of these may have changed over time. Since 2000/2001 competition season, in talent two was measured annually. A total 492 participated, divided across seven age categories (under 13 (U13), U14, U15, U16, U17, U18, U19) and resulting 953 measurements. Analyses variance showed an improvement from season 2009/2010 around 50% all...
To analyze how physical fitness (PF) improves in elite junior tennis players related to age, maturity, and performance level.Elite (n = 113 boys, n 83 girls) divided by level were monitored longitudinally from U14 U16. Maturity, upper lower-body power, speed, agility measured during subsequent competitive seasons. Improvement was analyzed per sex using multilevel analysis.PF components for boys girls improved over age (U14-U16) (ES .53-.97). In the more mature outscored less power U14-U16....
Fast reaction and good inhibitory control are associated with elite sports performance. To evaluate the reproducibility validity of a newly developed Badminton Reaction Inhibition Test (BRIT), fifteen (25 ± 4 years) nine non-elite (24 Dutch male badminton players participated in study. The BRIT measured four components: domain-general time, badminton-specific control. Five participants were retested within three weeks on components. Reproducibility was acceptable for time (ICC = 0.626, CV...
We conducted semistructured interviews with telemedicine program administrators as part of a national survey physicians and managers regarding attitudes toward, knowledge of, telemedicine. Telemedicine were interviewed factors affecting physician adoption interactive video (IAV) The seven networks which these affiliated represented "traditional" programs, primarily providing specialty teleconsultation via IAV. These programs located in different geographic regions, included both consulting...
Abstract This study examined the test-retest reliability, validity and feasibility of newly developed Dutch Technical-Tactical Tennis Test (D4T). new test is relevant for talent identification development in tennis. Thirty-two youth male tennis players (age 13.4 ± 0.5) were classified as elite (n = 15) or sub-elite 17) according to their position on national ranking list under 15 years (cut-off rank 50) Netherlands. Games, rallies different tactical situations (i.e. offensive, neutral...
This study investigated the influence of chronological (CA) and skeletal ages (SA), anthropometry, aerobic endurance lower limb explosive strength on developmental changes in repeated-sprint ability (RSA) soccer players aged 11–17 years. Participants were annually followed over 5 years, resulting 366 measurements. Multilevel regression modelling analysed longitudinal data aligned by CA SA (Model 1 2, respectively). After diagnosing for multicollinearity, it was possible to predict RSA with...
Sprint performance over short distances is a central component in young tennis players' development. This study aimed to examine the longitudinal development of sprint female players, and investigate differences between levels. Also potentially explanatory variables were investigated. Female players aged 10–15 (N = 167) participated a, mixed-longitudinal (n 48 elite; n 119 sub-elite). Players measured annually on 5 m as well for possible explaining (age, height, body mass, maturity status,...
The aim of this study is to examine whether technical characteristics predict current and future tennis performance youth players. Twenty-nine male players (age 13.40 ± .51) were assessed on anthropometrical (height, weight, maturity status) (ball speed, accuracy percentage errors) using an on-court test when they under-14 (U14). Game situations simulated, which either fixed or variable. variable game required consider the direction ball, as opposed where needed play every ball same side....
While tactical performance in soccer is associated with the players' and teams' collective actions context of game stimuli, how relates to executive functions (EFs) physical abilities should be examined. In this study, we examined these relationships among 81 Under-15 male players who underwent evaluation (FUT-SAT), EF tests (i.e.,(Stop-Signal Test Design Fluency Test)), (i.e.,(Maturity Offset, Yoyo Endurance II, Sargent Jump Test, Sprint Test)).
