Background. This research assumes the possible increase of athletic performance in any sport, by applying mental training techniques, particularly sensory submodalities in neurolinguistic programming. Aims. We studied the relationships between sensory submodalities in neurolinguistic programming. We wanted to check the degree of significance of the mean difference in the studied parameters and whether the resulting significance threshold fell within the objective parameters. Methods. We applied the Bandler & Thomson (2012) and Jacobson (2011) tests. These were applied to students of the Faculty of Physical Education and Sport, Babes-Bolyai University Cluj-Napoca. They completed the tests, with words describing feelings, perceptions and representations accompanying the description of motor acts. Motor acts are specific motor skills in every sport used in mental training. The words chosen by students who completed the questionnaires were able to provide information regarding the precision and accuracy of movement representations in mental training of FEFS students. There were two testing moments: T1 and T2, after 30 days. Results. We evaluated the results recorded in the three major categories of visual, auditory, and kinesthetic sensations in students of the experimental group for the Bandler & Thomson and Jacobson tests at the two time points. The statistical analysis of Bandler & Garner and Jacobson for paired samples (T1 and T2 moments) demonstrated no statistically significant differences (p>0.05), but there were many good and very good correlations in both tests between the values of the studied items. This is explained by the very small difference in time between the two test moments. In realizing ideomotor representations, all sensory submodalities are particularly important and underlie mental training. Conclusions. In the Bandler & Thomson, the statistical analysis of the correlation between the values of the studied items showed a very good positive correlation between SA - SK (auditory and kinesthetic sensations) and a good positive correlation between SV-SA (visual and auditory sensations) and SV - SK (visual and kinesthetic sensations). Regarding the Jacobson test, the statistical analysis of the correlation between the values of the studied items showed a very good positive correlation between SV - SA (visual and auditory sensations), SV - SK (visual and kinesthetic sensations), SV - SOG (visual and olfactory, gustatory sensations), SA - SK (auditory and kinesthetic sensations) and SK - SOG (kinesthetic and olfactory, gustatory sensations). A good positive correlation was obtained between SA - SOG. (auditory and olfactory, gustatory sensations). [ABSTRACT FROM AUTHOR]
