The SARS-CoV-2 virus pandemic has forced far-reaching changes in higher education. Isolation from peers and distance learning have significantly limited interpersonal contacts, which might have affected the mental well-being of students. Therefore, the aim of the study was to investigate the prevalence of depressive symptoms and the level of perceived stress during e-learning among Slovak students and to identify the variables that have the most significant impact on mental health among students. The study included 3051 participants, 1773 women (58%) and 1278 (42%) with a mean age of 22.37 years. The Perceived Stress Scale (PSS-10) and Beck Depression Inventory (BDI-II) were used to measure the severity of stress and depression level. In addition, an author’s survey was used assessing the areas of social life, education skills, economic field, nutrition habits, and drugs. Almost all study participants were characterized by increased stress level and 47% of them were depressed. Moreover, isolation affected women more, especially in terms of social life and economics. It seems necessary to implement appropriate support programs for students, which could have the potential to improve their psychological condition.

The representation of temperature measurement methods is worldwide, as is the number of industries that use them. Their utilization allows one to assess the object’s temperature relatively accurately and further according to the defined dependencies to evaluate its condition. In the medical sector, non-invasive temperature measurement methods are increasingly gaining ground. In our work, we focus on the design of a system for measuring skin temperature using digital DS18B20 thermometers. The technical design consists of the mechanical design of the sensor housing based on the requirements of healthcare professionals, the design of a 1-wire bus active pull-up driver with improved features, and the user software, allowing for the future implementation in various, not necessarily medical environments. The main contribution lies in optimizing the hardware design concerning the components’ parameters and surge protection. In the medical field, the aim was to compare changes in skin temperature in the shoulder region depending on the type of muscle contraction during static and dynamic components of movement and to record the thermal work of the muscle during activity in real-time. We experimented by applying temperature sensors to the deltoid muscle of the dominant limb in a temperature environment of 25.76 °C. In the experimental measurements, we demonstrated that during the three selected muscle work movements, there was a temperature change in the respective regions of the deltoid muscle for each of the three, which the temperature sensors could capture. Our results were statistically significant when comparing the baseline values, and the highest temperature reached. The level of significance $\alpha \leqslant 0.05$ and a low percentage of errors were valid.

Background and Study Aim. COVID-19 coronavirus pandemic has affected several areas of human and public life. The implementation of the restrictions affects free movement, leading to limited physical activity (PA) level. The main aim of the study was to determine the level of PA of university students in Slovakia during COVID–19 pandemics. Material and Methods. The sample consisted of 3128 university students. Data was obtained from students from three universities with different specializations. A questionnaire about lifestyle with questions about physical activity was used. The questionnaire was distributed using online communication systems of universities. The online questionnaire was answered by 3128 students. Results. Analyzed data were obtained from 3128 students. The results indicate that 38% of all students exercise 3-4 times per week, while 41% exercise 1-2 times per week, and 21% do not exercise at all, or exercise 1-2 times per month. Found weak positive correlation (r=0,337) was between the exercise frequency and perception of well-being, and a very weak positive correlation (r=0,187) between the exercise frequency and stress intensity. A moderate positive correlation was found between the perception of health and life energy (r=0,579). A moderate positive correlation was observed between the perception of health and physical strength (r=0,579). Conclusions. COVID-19 restrictions have been associated with the reduction of physical activity of the students. To avoid the negative effects of a sedentary lifestyle, it is necessary to promote activity among university students.

In the pilot experimental study eight men with an average age of 33.5 ± 3.64 years were tested. The probands were tested on the Biodex Balance System before and after the exercise of the abdominal muscles. Exercise was carried out to the subjectively perceived maximum. The file was deliberately composed of mentally and physically trained individuals. Evaluated was the stability index, the smaller the nominal value, the better the stability. After the workout stability parameters were significantly worse than before the exercise (p = 0.025). The fatigue of the abdominal muscles thus negatively affects the stability of the stand.

Background Combat sports are becoming increasingly popular worldwide. The link between core muscle function and combat performance has been recognized for some time, and the trend of sports physiotherapy has further emphasized core muscle strengthening for optimal performance. Aims The...
