Use of a step-platform in the preparation of female students, going in for sports aerobics, to fulfill elements of static and dynamic strength

Abstract

Aim: to determine the effectiveness of using a step-platform to improve the technique of performing elements with the manifestation of static and dynamic strength of female students engaged in sports aerobics. Material and methods. The study involved 20 female students of Kharkov higher educational institutions, who were engaged in sports aerobics in sports improvement groups. Research methods. The questionnaire was carried out among aerobics coaches in order to reveal their attitude to the use of a step-platform in the process of studying and improving the technique of elements of dynamic and static strength. The pedagogical experiment was carried out in 2 stages and lasted for 6 months from October 2019 to March 2020. At the first stage, the existing level of development of the physical abilities of the subjects was revealed, in particular, flexibility (bending forward from a sitting position), power abilities (flexion, extension of the arms in a lying position, hanging on bent arms, lifting the body in a sitting position in 1 min.), Speed ( run 60 m), agility (shuttle run 4x9 m), endurance (run 1000 m) and techniques for performing basic elements of dynamic and static force, which were taken as control ones. The assessment of each of the control elements was carried out on a 10 point scale. The athlete received the highest score for the impeccable performance of the element, for each gross error she lost 3 points, the average 2, and the small 1 point, loss of balance and fall during the execution of the element did not give the subjects a single point. Results. A significant increase in flexibility, strength and endurance, as well as marks for the technique of performing elements of dynamic and static strength, was revealed. Significant relationships were revealed between the scores for the STRADDLE LATERAL PUSH UP and HINGE PUSH UP technique and the indicators of flexion and extension of the arms in the supine position and weight on bent arms. Significant correlations were also revealed between the scores by STRADDLE SUPPORT 1/1 TURN and LIFTED STATIC WENSON SUPPORT and the indicators of forward bending of the trunk and lifting of the trunk to the sitting position in 1 min. Conclusions. Provided sets of exercises using a step platform. The exercises are aimed at developing physical qualities for performing elements with the manifestation of dynamic and static strength. The exercises are also aimed at learning and improving the technique of these elements in various conditions. Their effectiveness in physical and technical preparation of girl students for the fulfillment of elements with the manifestation of dynamic and static strength in sports aerobics has been experimentally proved.
