Calculation-graphical assessment of student's ability to differentiate the sensations of running load intensity

Problem and purpose. The problem of running exercises usage in independent physical culture trainings as one of the most important means of physical development is analyzed and formulated in the article. In our years-long practical work we often stressed that doing long-distance worming-up exercises students could not control running intensity in accordance with the necessary level of affecting the cardio-vascular system relying on the heart-beat frequency data (HR). Overrating their abilities at the beginning of the distance students developed too high speed, grew tired very soon and frequently switched over to walking. In this case, as a rule, the HR was fixed at 180 beats per minute. The purpose of the article is to work out the technology of assessing the ability of a student to differentiate his/her sensations of the physical load intensity in running proportionately to the heart rate. The methodology of the research is grounded on (1) the theory and methods of university students physical culture education [Balsevich, 2002, Balsevich, 2009; Vilensky, 2001; Platonov, 1990]; (2) information about the development of professionally applied physical training for students [Yevseyev, 1999; Ilyinich, 1991; Fedyakin, 2010; Viktorov, 2018; Sidorov 2005]; (3) scientific - methodological literature on the problems of physical education published abroad [Konkabayeva, 2016; Mena, 2017; Marongiu 2015; Galle, 2015; Akhmadyan, 2015]. The results of the experiments showed the following: at the end of the running characteristics test, the HR of the students was 181±12 beats/min, which to a great degree corresponds to the physical load of well-trained sportsmen. The data obtained demonstrated that the underdeveloped skill of differentiating the sensations of physical load intensity can lead to performing long-distance running exercises in anaerobic mode and not in the required aerobic mode. This fact does not allow to solve properly the problem of raising the physical fitness level in students developing their aerobic possibilities. And the potential for students' independent monitoring their physical load when running also looks quite problematic [Astrakhantsev1, Duruda2, Kondratyeva3, Kulikiv4, Lagutkina5]. Conclusion. The issues of correlation between the planned and fulfilled physical exercises could be solved with greater success if the person involved in physical training would have the necessary “instrument” to measure objectively the ability to differentiate the sensations of running intensity relying on the HR in his/her independent physical culture exercises.
