SUBJECTIVE EVALUATION OF DIFFERENT LOAD INTENSITY IN JUDO TRAINING

Marino Tavra, Goran Kuvačić, Alen Miletić

The aim of this research was to ascertain the possibility of subjective evaluation of different load intensities in judo training. It was assumed that there was a strong connection between the subjective evaluation of the load intensity and the perceived heart frequency in examinees, with different training load intensities. The sample of examinees in this research consisted of 10 judokas, of average age 21±3.2 years, with training experience of 11±2.8 years. All the examinees are competitors and medal winners at the national level in the following weight classes: -73kg, -81kg, -90kg, -100kg. The sample of variables consisted of 10 measured parameters: the evaluation of subjective load intensity of an examinee (ESLI) in 5 points, and perceived heart frequency (HF) also in 5 points of measuring, or, training phases. A modified Borg RPE subjective load intensity scale CR10, ranging from 0 to 10, was used in the evaluation of subjective intensity variables. To ascertain the actual presence of several levels of load intensity, the univariate variance analysis was used for repeated measuring with Fisher LSD test in post-hoc analysis. The insight into the results showed the four levels of load intensity: low, moderate, high and maximum. The correlation analysis showed significant relationship between the ESLI and HF variables in two measuring points, at low and high intensity. The low relation between the ESLI and HF variables in other measuring points is explained by small number of examinees, relatively low variability of the RPE scale, and the application of only one parameter of objective load evaluation (HF). The research pointed out the importance of subjective evaluation of load intensity, which can be used as a good tool of training process planning and programming.
