'Gravitron' Assisted Pull-Up Machines in Strength Building as Part of Physical Education Class in the Senior Years of Secondary School

摘要

In order to meet the State Educational Standard for Secondary Schools in the Russian Federation, a comprehensive test investigating physical fitness in senior students was conducted. The sample consisted of male youth attending Astrakhan secondary schools. This test showcased that physical fitness in said students was underdeveloped. By using the weight machines, "Gravitron" assisted pull-up machine to be exact, the students were able to significantly improve their fitness and strength building capacities in order to prepare for the GTO pull-up tests on a horizontal bar. The research materials for the study were physical fitness test scores obtained from the secondary school students in Astrakhan (Russia) along with medical commission reports. In order to assess physical fitness in said sample, the students were asked to perform pull-ups on a horizontal bar. The calculations were computed using Statistica 10 analytics software package (USA) and its applications. The correlation analysis was performed applying the Pearson correlation coefficient. The PE curriculum for the experimental group introduced obligatory pull-ups on a horizontal bar. As a result, the strength building capacity of said students increased significantly over 6 months doing this exercise. The results of this study prove the effectiveness of using the "Gravitron" assisted pull-up machine (Russia) in PE classes in senior school which facilitates higher physical fitness scores when performing pull-ups on a horizontal bar.
