In this study we made cross-sectional measurements of physique, body composition, and motor performance in school-age boys, and applied wavelet interpolation to the respective growth and development distance values. We then conducted a trend analysis of the aging distance curve and analyses of the maximum peak velocity (MPV) and local (LPV) shown in age change velocity curve against to age. The subjects were 469 schoolboys aged 7 to 14 years. Physique (height, weight, body mass index: BMI), body fat percentage: %BF, motor performance (20 m run, pro-agility test, vertical jump, standing long jump, side step, rebound jump index) were measured. Wavelet interpolation was applied to the age distance values for physique, %BF, and motor performance, and the following results were obtained. The MPVs of age shown in the growth velocity curves for height and weight were 13.2 and 13.5 years, which were similar to conventional findings. Overlap was shown in the LPVs School of Commerce Senshu University Faculty of Human Health Science, Hachinohe University Business Administration and Computer science, Graduate School of Aichi Institute of Technology Faculty of Sports Science, Waseda University Aichi Institute of Tecnology

These results are new findings. In motor performance development a mixed type was shown based on the nerve type of Scammon and the general growth pattern, but in the appearance of the LPV in the development velocity curves for each motor performance parameter, the 20 m run, proagility test, and side steps were more strongly related to the nervous system. In the vertical jump and standing long jump, the standing long jump depended more greatly on general growth pattern. These are the main findings to be emphasized. Ⅰ. 緒 言 Scammon Fujii et al
