Features of the methodology of the development of cadets’ physical qualities during kettlebell lifting activities

La metodología de los autores sobre el desarrollo de las cualidades físicas de los cadetes durante las actividades de levantamiento de pesas se confirma en el artículo y se verifica su eficiencia. 86 cadetes participaron en la investigación. Se formaron los grupos experimentales (EG, n=29) y control (CG, n=57). La investigación se realizó de acuerdo con las siguientes pruebas: carrera de 100 m, carrera de 3 km, inclinación hacia adelante del cuerpo, mantener el cuerpo en posición horizontal, ejercicio de barra de levantamiento, balanceo de cadera, flexión en barras paralelas, ejercicio de poder complejo. Al final del estudio, la mayoría de las pruebas establecieron un nivel significativamente mejor del desarrollo de las cualidades físicas de los cadetes. The authors’ methodology of the development of the physical qualities of cadets during kettlebell lifting activities is substantiated in the article and its efficiency is checked. 86 cadets participated in the research. The experimental (EG, n=29) and control (CG, n=57) groups were formed. The research was conducted according to the following tests: 100 m race, 3 km race, forward inclination of the body, holding the body in a horizontal position, pull-up bar exercise, hipswing-up, push-up on parallel bars, complex power exercise. At the end of the study, a significantly better level of the physical qualities’ development of cadets engaged in kettlebell lifting activities according to the authors’ methodology was established by the majority of tests

Influence of fitness technologies on the student youth’s physical qualities development

El artículo estudia la influencia de las tecnologías modernas de fitness en el nivel de desarrollo de las cualidades físicas de los estudiantes de ambos sexos. 232 estudiantes (88 hombres y 144 mujeres) participaron en la investigación. Se formaron dos grupos experimentales (GE, 47 hombres y 71 mujeres) y dos grupos de control (GC, 41 hombres y 73 mujeres). Los estudiantes de GC participaron en el sistema tradicional de educación física, y los estudiantes de GE en el sistema metódico experimental, basado en los tipos modernos de tecnologías de acondicionamiento físico. Las pruebas de aptitud física de los estudiantes se llevaron a cabo de acuerdo con ejercicios que caracterizan el desarrollo de cualidades físicas. The article studies the influence of modern fitness technologies on the level of development of the physical qualities of students of both sexes. 232 students (88 men and 144 women) participated in the research. Two experimental groups (GE, 47 men and 71 women) and two control groups (GC, 41 men and 73 women) were formed. GC students participated in the traditional physical education system, and GE students in the experimental methodical system, based on modern types of fitness technologies. The physical fitness tests of the students were carried out in accordance with exercises that characterize the development of physical qualities

Professional Development of Future Physical Culture Teachers during Studying at Higher Educational Institutions

The work was focused on exploring the motives for choosing a teaching profession and the development level of motivation for continuing professional growth in the process of studying at a higher educational institution; the analysis of the levels of readiness of the students of the Faculty of Physical Education for continuing studying; the diagnostics of the dependence of the level of motor readiness of students, who are future physical culture teachers, on the level of their motivation and readiness for continuous professional development. Experimental studies were conducted at the Physical Education Faculty of the Taras Shevchenko National University «Chernihiv College». The study was conducted in 2016-2017 (during the 1st year of study) and in 2019-2020 (during the 4th year of study). The experimental group consisted of 67 students between the ages of 17 and 22. The studies showed the dependence of the level of motor readiness of students on the level of their motivation and readiness for continuous professional development. The indicators of motor activity of the fourth-year students with high levels of motivation and readiness for continuous professional development were increased concerning the amount of the motor activity that is characteristic of the professional activity of a physical culture teacher. The indicators obtained during the study indicate that students, who are aware of the need for professional development master the content of the curriculum better during the period of study and, as future physical culture teachers, better understand the purpose and objectives of education of pupils

Measurement of the cross-section ratio sigma_{psi(2S)}/sigma_{J/psi(1S)} in deep inelastic exclusive ep scattering at HERA

The exclusive deep inelastic electroproduction of $\psi(2S)$ and $J/\psi(1S)$ at an $ep$ centre-of-mass energy of 317 GeV has been studied with the ZEUS detector at HERA in the kinematic range $2 < Q^2 < 80$ GeV$^2$, $30 < W < 210$ GeV and $|t| < 1$ GeV$^2$, where $Q^2$ is the photon virtuality, $W$ is the photon-proton centre-of-mass energy and $t$ is the squared four-momentum transfer at the proton vertex. The data for $2 < Q^2 < 5$ GeV$^2$ were taken in the HERA I running period and correspond to an integrated luminosity of 114 pb$^{-1}$. The data for $5 < Q^2 < 80$ GeV$^2$ are from both HERA I and HERA II periods and correspond to an integrated luminosity of 468 pb$^{-1}$. The decay modes analysed were $\mu^+\mu^-$ and $J/\psi(1S) \,\pi^+\pi^-$ for the $\psi(2S)$ and $\mu^+\mu^-$ for the $J/\psi(1S)$. The cross-section ratio $\sigma_{\psi(2S)}/\sigma_{J/\psi(1S)}$ has been measured as a function of $Q^2, W$ and $t$. The results are compared to predictions of QCD-inspired models of exclusive vector-meson production.Comment: 24 pages, 8 figure

Combined QCD and electroweak analysis of HERA data

A simultaneous fit of parton distribution functions (PDFs) and electroweak parameters to HERA data on deep inelastic scattering is presented. The input data are the neutral current and charged current inclusive cross sections which were previously used in the QCD analysis leading to the HERAPDF2.0 PDFs. In addition, the polarisation of the electron beam was taken into account for the ZEUS data recorded between 2004 and 2007. Results on the vector and axial-vector couplings of the Z boson to u- and d-type quarks, on the value of the electroweak mixing angle and the mass of the W boson are presented. The values obtained for the electroweak parameters are in agreement with Standard Model predictions.Comment: 32 pages, 10 figures, accepted by Phys. Rev. D.
