Introduction: The physical health of children and adolescents is directly related to school physical training quality. The improvement of adult sports effectiveness results from a concise protocol with standardized exercises. Rope skipping exercise lacks kinematic studies applied to children and adolescents. Objective: Provide a theoretical reference for jump rope exercise training for children and adolescents. Methods: Eight children aged six to eight years old were recruited to jump at a frequency of 80 and 120 jumps per minute controlled by a metronome. The technique was divided into three stages: impulse, suspension, and landing. Control in the knee joint exoskeleton balance was investigated by computerized baropodometry with differentiation of rotational angular velocity by rotational angular acceleration via Butterworth filter. After noise cleaning and multiplication, an adjustable amplification factor returned to the inlet with inertial compensation torque. Results: Initially, the impulsing force is about three times the individual’s gravity. This value and the center of mass acceleration decrease in time. The initial force is proportional to the velocity of its decrease during the impulse, and the opposite occurs with the landing force. Higher intensity is observed when raising the frequency. Conclusion: The fluctuation in the force curve in the landing phase after 20 jumps indicates low muscle strength in lower limbs to maintain activity. A speed of 80 jumps per minute controlled by music in a playful environment is recommended for children. Evidence Level II; Therapeutic Studies – Investigating the results.

“…It is possible for all this to happen with digitally literate individuals. Digital literacy is a continuous learning through technology in today's information age and it is one of the competencies that individuals who are in a state of discovery should have in order to make their learning more effective (Alexandru et al, 2021).…”

The purpose of this study is to investigate the determination of the formation of singing skills of future music teachers through digital resources. The quantitative research method was used in the study, and the research was conducted in the fall semester of 2021–2022. 376 volunteer music teachers who continue their studies in Kazakhstan participated in the study. In the study, 4 weeks of online training was provided to music teachers. In the study, the ‘digital music platform’ measurement tool developed by the researchers and compiled by experts in the field was used. The measurement tool was delivered and collected by the online method of music teachers. The analysis of the data was carried out using the SPSS programme; frequency analysis was carried out using the t-test; and the results obtained were added to the study accompanied by tables. According to the survey results, in live lessons, music teachers use the songs with the formation and this takes place where digital content is also very low. In the event of very frequent use, it was seen that by projecting courses in distance education systems the music rates are quite high.
