Neurofeedback training in the subject under study increased the amplitude of the monitoring component of ERPs generated in the anterior cingulate cortex, accompanied by an increase in beta activity over the medial prefrontal cortex. Taking these changes together, it can be concluded that that even a few sessions of neurofeedback in a high performance brain can significantly activate the prefrontal cortical areas associated with increasing confidence in sport performance.

Material/MethodsThis study utilised the Chi-square test of the independence measurement model and student's T test. It also analysed 7 scenarios. A final survey-list consisted of the 38 items of competences and it was completed by 243 young people who took part in this study; the sample included 151 (67.7%) athletes training individual disciplines and 72 (32.3%) team disciplines. ResultsThe statistically significant results between the groups are in terms of competence (scenarios 3 and 6). There were no statistically significant differences between the groups in terms of life experience. ConclusionsResults in both parts of the study confirmed the three hypotheses. It turned out that the type of sport does not affect the course of the dual career in professional athletes.

BackgroundThe aim of the research was an evaluation of 2 training programs covering the same standard physical activity in the initial stage (warm-up) and the main (motor exercises) as well as a separate end part in Program A of stretching and in Programme B of vibration training designed to improve the level of body balance.Material/MethodsWe tested 40 randomly chosen students of the Academy of Physical Education and Sport in Gdansk, subsequently divided into two 20-person groups: C (average age 21.3±1.2), and E (average age 21.8±1.1). The training of body balance was conducted for 8 weeks: we used in Group C Program A and in group E Program B. The evaluation of body balance was done 3 times: at the beginning, at midway point, and at the end of the experiment. The stabilographic tests with posture-graphical method and the task of 1-leg balance standing with eyes closed was used.ResultsIt was found that in the first examination both groups did not significantly differ in terms of the tested parameters of balance. During the training process we obtained increased time of maintaining balance on 1 leg. This difference was significant between tests 1 and 2 both for Group C (p=0.0002) and for E (p=0.0034), while between the tests 2 and 3 in Group E (p=0.0213) only.ConclusionsThe training Program B is more effective to maintain balance on 1 leg when compared to Program A.
