The aim of the master's thesis was to determine the effect of kinesiotaping on the strength of the upper body, specifically to establish whether there is a statistically significant difference in the explosive strength of the upper body with the application of kinesiotape. The participants were students of the Faculty of Kinesiology in Osijek, aged 19 to 31, from the first to the fifth year of study. The research was conducted at the Faculty of Kinesiology in Osijek. The explosive strength of the upper body was measured using the test of backward overhead medicine ball throw. The kinesiology tape was applied to the lower back, paravertebrally (along the spine), mostly on the lower part of the multifidus muscle. The tape was applied in the shape of the letter "I". The Spearman correlation coefficient was used as an indicator of the relationship between morphological characteristics and upper extremity strength indicators. A paired T-test, or the Wilcoxon test for dependent variables, was used to test the statistical significance of the difference in results between measurements with kinesiotaping and measurements without kinesiotaping. It was found that there is a statistically significant difference between the results of measurements with kinesiotaping and measurements without kinesiotaping, indicating that kinesiotaping affects the explosive strength of the upper body, specifically the results of the medicine ball throwing test.
