Skeletal maturation, fundamental Motor skills, and Motor Performance in preschool children.
Scandinavian journal of medicine & science in sports, 2018Co-Authors: Duarte L. Freitas, António M. Antunes, José Maia, Élvio R. Gouveia, Martine Thomis, Johan Lefevre, Berthold Lausen, Robert M. MalinaAbstract:Relationships among skeletal age (SA), body size and fundamental Motor skills (FMS) and Motor Performance were considered in 155 boys and 159 girls 3-6 years of age. Stature and body mass were measured. SA of the hand-wrist was assessed with the Tanner-Whitehouse II 20 bone method. The Test of Gross Motor Development, 2nd edition (TGMD-2), and the Preschool Test Battery were used, respectively, to assess FMS and Motor Performance. Based on hierarchical regression analyses, the standardized residuals of SA on chronological age (SAsr) explained a maximum of 6.1% of the variance in FMS and Motor Performance in boys (ΔR2 3 , range 0.0%-6.1%) and a maximum of 20.4% of the variance in girls (ΔR2 3 , range 0.0%-20.4%) over that explained by body size and interactions of SAsr with body size (step 3). The interactions of the SAsr and stature and body mass (step 2) explained a maximum of 28.3% of the variance in boys (ΔR2 2 , range 0.5%-28.3%) and 16.7% of the variance in girls (ΔR2 2 , range 0.7%-16.7%) over that explained by body size alone. With the exception of balance, relationships among SAsr and FMS or Motor Performance differed between boys and girls. Overall, SA per se or interacting with body size had a relatively small influence in FMS and Motor Performance in children 3-6 years of age.

Motor Performance, body fatness and environmental factors in preschool children
Journal of sports sciences, 2018Co-Authors: António M. Antunes, Duarte L. Freitas, José Maia, Donald Hedeker, Élvio R. Gouveia, Martine Thomis, Johan Lefevre, Lisa M. BarnettAbstract:ABSTRACTThe first aim of this study was to investigate the relationship between Motor Performance and body fatness among 3- to 5-year-old children. The second aim was to assess whether this relationship works similarly for boys and girls. We also investigated whether socioeconomic status (SES) and geographical area when children are aged 3 years old predicts the Motor Performance of 4 and 5-yr-old children. Motor Performance was assessed through the Preschool Test Battery, while body fatness was estimated through body mass index (BMI). SES and geographical area were assessed via parent proxy-report questionnaires. BMI was negatively associated with standing long jump. The association of BMI and Motor Performance was not statistically different for boys and girls. Children from low SES performed better than high SES peers in tennis ball throw for distance. Rural children were better performers than urban peers in standing long jump. Rural area at baseline was also predictor of standing long jump and tennis...

Tufts Assessment of Motor Performance: An empirical approach to identifying Motor Performance categories
Archives of physical medicine and rehabilitation, 1991Co-Authors: Stephen M. Haley, Larry H. Ludlow, Bruce M. Gans, Ruth M. Faas, Constance A. InacioAbstract:Abstract The Tufts Assessment of Motor Performance (TAMP) is a criterion-referenced test that measures Motor Performance capabilities of basic self-care skills, mobility and physical aspects of communication. Discrete Motor Performance tasks were identified within each of the 32 items. The purpose of this paper is to report the results of an empirical method of determining the factor structure underlying the Motor Performance tasks of the TAMP. Initially, Motor Performance tasks were categorized into a priori groupings based on previous literature and clinical judgment. The TAMP was administered to 206 children and adults (age range 6 to 86 years) with physical disabilities. Diagnoses included a variety of musculoskeletal and neurologic disorders. A principal-factor analysis was used to organize and cluster the item tasks into appropriate common factors. Seven factors were identified that accounted for 70.6% of the total variance for the assistance dimension; similar results were obtained for other measurement dimensions of the TAMP. The defined factor structure has patterns of similarity to the Motor Performance variables as defined by clinical judgment; however, the tasks were organized into factors that were more functionally oriented than expected. The results provide a framework for which the Motor Performance tasks of the TAMP might be organized into scales that identify essential Performance constructs for rehabilitation. The results permit examination of the nature and clinical importance of these common Motor Performance factors for clinical evaluation and the description of functional disability.

Quiet Eye and Motor Performance: The Longer the Better?
Journal of sport & exercise psychology, 2018Co-Authors: André Klostermann, Ralf Kredel, Ernst-joachim HossnerAbstract:The quiet-eye (QE) phenomenon has been found to predict subsequent Motor Performance. However, it remains unclear whether this effect also holds for considerably extended QE durations. Therefore, i...

The “quiet eye” and Motor Performance: Task demands matter!
Journal of experimental psychology. Human perception and performance, 2013Co-Authors: André Klostermann, Ralf Kredel, Ernst-joachim HossnerAbstract:Evidence suggests that superior Motor Performance coincides with a longer duration of the last fixation before movement initiation, an observation called “quiet eye” (QE). Although the empirical findings over the last two decades underline the robustness of the phenomenon, little is known about its functional role in Motor Performance. Therefore, a novel paradigm is introduced, testing QE duration as an independent variable by experimentally manipulating the onset of the last fixation before movement unfolding. Furthermore, this paradigm is employed to investigate the functional mechanisms behind the QE phenomenon by manipulating the predictability of the target position and thereby the amount of information to be processed over the QE period. The results further support the assumption that QE affects Motor Performance, with experimentally prolonged QE durations increasing accuracy in a throwing task. However, it is only under a high information-processing load that a longer QE duration is beneficial for throwing Performance. Therefore, the optimization of information processing, particularly in Motor execution, turns out to be a promising candidate for explaining QE benefits on a functional level.
