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.

Previous research has indicated that spectators can influence the outcomes of athletic competitions. In Study 1, spectators' perceptions of their ability to influence the contests were examined. Results indicated that high levels of identification with sports teams were related to greater perceptions of influence. It was further predicted that high-identification fans would exhibit the most intense affective reactions to competition outcome. In Study 2 this proposition was tested and supported. High-identification fans reported an increase in pre- to postgame positive emotions following a win and an increase in negative emotions following a loss. Emotional changes were minimal for fans low in team identification. Finally, a third study was used to examine possible changes in team identification as a result of competition outcome for historically successful and marginally successful teams. The results indicated that although past team success was an important predictor of identification level, levels were not affected by game outcome.

Knowledge of how stiffness, damping, and the equilibrium position of specific limbs change during voluntary motion is important for understanding basic strategies of neuromotor control. Presented here is an algorithm for identifying time-dependent changes in joint stiffness, damping, and equilibrium position of the human forearm. The procedure requires data from only a single trial. The method relies neither on an analysis of the resonant frequency of the arm nor on the presence of an external bias force. Its validity was tested with a simulated forward model of the human forearm. Using the parameter estimations as forward model input, the angular kinematics (model output) were reconstructed and compared to the empirically measured data. Identification of mechanical impedance is based on a least-squares solution of the model equation. As a regularization technique and to improve the temporal resolution of the identification process, a moving temporal window with a variable width was imposed. The method's performance was tested by (a) identifying a priori known hypothetical time-series of stiffness, damping, and equilibrium position, and (b) determining impedance parameters from recorded single-joint forearm movements during a hold and a goal-directed movement task. The method reliably reconstructed the original angular kinematics of the artificial and human data with an average positional error of less than 0.05 rad for movement amplitudes of up to 0.9 rad, and did not yield hypermetric trajectories like previous procedures not accounting for damping.

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.

study, we further identify apnea occurrence at each second, using the same criteria defined by AASM. Note that this per-second identification contains richer information, and can be converted to ten-second apnea events, but not vice versa. For convenience, we still use the term “apnea event” to refer to
