Didelio intensyvumo intervalinės treniruotės (DIIT) širdies ir kraujagyslių ligų prevencijai

Purpose: Define the state of art about the process of forming the knowledge about high-intensity interval training (HIIT) for health promotion in the cohort of students of Lithuanian Sports University. Methods: The two research studies were carried out. The first research – HIIT impact on the cardiovascular system and the second – acquiring the competencies for counseling of HIIT in the cohort of students of Lithuanian Sports University. In the first research, the 10 healthy adult males performed the HIIT session with the load being 1 W per 1 kg of the body mass, according to the Wingate test protocol. The second research-targeted students of Lithuanian Sports University who engaged in study programs related to health promotion with the purpose to reveal the peculiarities of their study process obtaining the competencies in advising on what is important in the applications of HIIT. Results: For the first research, results showed that the body responds to intensive exercise bout by mobilization cardiovascular abilities to meet the demands of muscular efforts. ST-segment depression significantly increased immediately after training sessions. Such exercises significantly affected the CVS. The second research revealed that the majority of participants, i.e., 81%, have heard about HIIT, some of them at school – 38%. Sports science has been listed as the course where HIIT is most studied (50%). In addition, 31% of last year's students indicated that they had enough skills for HIIT application compared to level 1, where none of the participants reported having them. Also, 60% of the first-year students felt they had no skills compared to 31% of the final year students. Cardio- HIIT is practiced by 38% of participants, and the average time is 20 to 30 minutes. The mentioned benefits of the HIIT were: endurance (26%), short time (23%), and loss of weight (8%). HIIT was recommended by the majority of last year's students (65%) compared to 1st-year students (35%). Conclusions: HIIT significantly affected the cardiovascular system during exercising, and this exercising technique involves some risks. HIIT has to be recommended only for individuals who have exercising experience or have undergone a medical examination and have a doctor's permission for such training. So obtaining the competencies in advising on what is important in the applications of HIIT is actual in the study process of health professionals. The first-year students have some knowledge about the HIIT method, but they hope to improve such competence in the study process. Last year students note that their competencies still need to be improved by ourselves
