However, research has been focused mostly on club team players, 2 , 5 – 9 and the information that describes national team players and their recruitment/selection process seems to be scarce. At the national team level, the pioneer work of Erčulj et al 10 examined the physical parameters

This study focuses on identification of children with motor coordination problems and investigates whether the incidence of children with such problems in a normal school setting in Norway is comparable to that found in other countries using the same tests and criteria. The study also examines whether there would be any agreement between two motor tests, the Test of Motor Proficiency (TMP) and the Test of Motor Impairment (TOMI), and teachers’ judgment in identifying clumsiness among 360 children 10 years of age. The results showed that while the three different assessment methods identified about the same number of children with such problems (5-5.6%), each measure identified a somewhat different set of children. The lack of agreement demonstrates the difficulty in assessing subtle motor coordination problems or clumsiness.

The theory of deliberate practice postulates that experts are always made, not born. This theory translated to the youth-sport domain means that if athletes want to be high-level performers, they need to deliberately engage in practice during the specialization years, spending time wisely and always focusing on tasks that challenge current performance. Sport organizations in several countries around the world created specialized training centers where selected young talents practice under the supervision of experienced coaches in order to become professional athletes and integrate onto youth national teams. Early specialization and accurate observation by expert coaches or scouts remain the only tools to find a potential excellent athlete among a great number of participants. In the current study, the authors present 2 of the problems raised by talent search and the risks of such a search. Growth and maturation are important concepts to better understand the identification, selection, and development processes of young athletes. However, the literature suggests that sport-promoting strategies are being maintained despite the increased demands in the anthropometric characteristics of professional players and demands of actual professional soccer competitions. On the other hand, identifying biological variables that can predict performance is almost impossible.

This study investigated whether the TOMI (Stott, Moyes, & Henderson, 1984), a motor skills test recommended for the identification of children who are physically awkward (Sugden, 1985; Wall, Reid, & Paton, 1990), contains biased items. Findings of a study by Causgrove and Watkinson (1993) indicated that an unexpectedly high proportion of girls from Grades 3 to 6 were identified as physically awkward, and the authors suggested that the TOMI may be biased in favor of boys. In the present study, this suggestion was investigated through comparison of performances of TOMI subtest items by boys and girls from Grades 1 to 6. Chi-square analyses on each of the eight test items revealed significant performance differences between boys and girls on the two ball skills tasks of catching and throwing (p < .0001) at Age Bands 3 and 4; a significantly greater proportion of boys than girls age 9 to 12 years passed the catching and throwing tasks. A significant performance difference was also found on the tracing task at Age Band 1, with more girls passing tracing than boys. Implications for future research requiring the identification of children who are physically awkward are discussed.

This investigation is concerned with the identification and assessment of Singaporean primary school children who have developmental coordination disorder (American Psychiatric Association, 1987). The present study forms part of a larger project concerned with the suitability of currently available assessment techniques and intervention programs for use in Singapore. In this paper the usefulness of the Movement ABC Checklist and Test as an assessment instrument is explored. The data on a sample of 212 7- and 8-year-olds compared favorably with data from the standardized sample in the United Kingdom. Age and gender differences were similar, and the effects of increasing task difficulty within the checklist were generally confirmed. The checklist identified 15.6% of children as having movement problems or being at risk, which was close to the value obtained in the U.K. The Movement ABC Test provided evidence of the validity of this figure as it successfully differentiated the selected children from age-matched controls who scored well on the checklist. Although some of the items in both instruments need modification, the results suggest that the Movement ABC package is a workable research tool in the Singaporean context.

Objective measures of recovery from football match play could be useful for assessing athletes’ readiness to train, if sensitive to preceding match load.
To identify the sensitivity of countermovement-jump (CMJ) performance and concentration of salivary testosterone and cortisol relative to elite football match load.
CMJ performance and salivary hormones were measured in 18 elite football players before (27, 1 h) and after (0.5, 18, 42, 66, 90 h) 3 consecutive matches. Match load was determined via accelerometer-derived PlayerLoad and divided into tertiles. Sensitivity of CMJ performance and hormone concentrations to match load was quantified with t statistics and magnitude-based inferences (change in mean as % ± 90% confidence interval) derived with a linear mixed model.
Jump height was reduced in medium and high load at 0.5 h (10% ± 7% and 16% ± 8%) and 18 h (7% ± 4% and 9% ± 5%) postmatch. There was a 12% ± 7% reduction in ratio of flight time to contraction time (FT:CT) in high load at 0.5 h post, with reductions in medium and high load at 18 h. Reductions in FT:CT persisted at later postmatch time points than changes in jump height. Increased cortisol (range 55–165%) and testosterone (range 17–20%) were observed in all match loads at 0.5 h post, with individual variability thereafter.
Measures of CMJ performance and hormonal concentrations were sensitive to levels of A League football match load. Although jump height was reduced immediately postmatch, FT:CT provided a more sensitive measure of recovery. Football match play induces an acute hormonal response with substantial individual variability thereafter.

In an attempt to improve sporting success at both club and national standards, governing bodies such as the Rugby Football League (England) have resourced talent identification and development (TID) programs to aid selection and training processes for young “talented” players. 1 Clubs are also
