Abstract

The purpose of this study was to build a model for classification of motor and functional fitness in adolescent female students. To achieve this purpose, girls in 7 th (n=31), 8 th (n=26), and 9 th grade (n=28) were recruited with appropriate parental consent. To build the classification model, each adolescent performed and number of motor tests and the Stange, Genchi, Serkin tests of functional state. Canonical discriminant function analyses were conducted to determine the motor and functional fitness contributions. Two significant functions (p<.001) resulted with the first function explaining 86.8% and the second 13.2% of the variance between grade levels. Based on the model, it was possible to classify girls' grade and thus biological age based on the performed tests. Structural coefficients from the first canonical discriminant function pointed to substantial difference between girls in 7 th grade compared to 8 th and 9 th grade at the end of motor coordination's development as well as speed, power, and Stange's test results. Structural coefficients of second canonical discriminant function pointed to substantial difference between girls in 8th and 9 th grade based on static and relative arm muscle strength. For improving and fully developing the pedagogic control of girls' motor and functional fitness, the first discriminant function should be used as it explained most of the grade differences.

Motor abilities: methods of strength and strength endurance development in middle-school-aged boys in a 4-week physical training cycle

“…The study ascertained that the use of the combined method of strength development and the circuit training method in a one-month physical training cycle positively affected the overall development of motor abilities in the 6 th -8 th grade boys. The obtained results of the study characterize the peculiarities of the dynamics of middle schoolers' motor fitness and supplement the data of Ivashchenko et al [17], James et al [18] on the holistic character of motor abilities development in children and adolescents; the data of Blagrove et al [19], Prykhodko [20] on the regularities of motor abilities development in children and adolescents.…”

Movement Coordination: Factor Structure of Development in 5th-7th Grade Girls

“…The works by Ivashchenko, Khudolii, Iermakov, Lochbaum, Cieślicka, Zukow, Nosko, and Yermakova, (2017), Ivashchenko, Khudolii, Yermakova, Pilewska, Muszkieta, and Stankiewicz, Błazej (2015) highlight the need for pedagogical control of the level of motor preparedness of schoolchildren; Ivashchenko, Yermakova, Cieślicka, and Śukowska (2015), argue that the level of coordination abilities development influences the effectiveness of teaching children and adolescents; points out the need for programming the development of coordination abilities.…”

Simulation of the regularities of physical exercises learning process of boys aged 8 years old

“…In previous studies, we observed a high discriminant and predictive ability of the functions received: in assessing the motor preparedness of children and adolescents [33,34]; in the classification of strength loads among schoolchildren of junior grades [35,36]; in the classification of motor readiness, taking into account the level of training [24,37].…”
