Background: The aim of this study is to determine the relationship between selected components of body composition and the phase angle specified by bioelectrical impedance analysis, depending on the level of physical activity among students. Materials and Methods: The study group consisted of 484 university students from Krosno. The diagnostic survey method (IPAQ-SF), measurements of highs, and analysis of body composition components (BIA) were used. The relationship between variables was determined using the χ² test, the V-Kramer coefficient, and Spearman’s rho coefficient. Results: University students in physical education demonstrated the highest level of physical activity and the lowest incidence of excessive body mass. Among the participants, 28.1% did not engage in any physical activity, or their level was insufficient. The PhA level was correlated with lean body mass and muscle mass. The correlation between higher levels of PA and PhA values was statistically significant, as was the relationship between self-assessment of physical fitness and the level of PA determined by IPAQ-SF. Conclusions: Preventive actions and educational programs, especially about spending leisure time in active ways, should be particularly targeted at students of disciplines with a significant amount of sedentary classes.

Introduction: Unhealthy eating habits combined with low levels of physical activity and cardiorespiratory fitness pose a serious threat to the health of young people. The aim of this research was to determine the relationship between selected components of body composition, the occurrence of eating disorders, and cardiorespiratory fitness (CRF) and physical activity levels among university students. Material and Methods: This study was conducted among 254 students at a university in Poland. It included the measurements of body height, body composition analysis using bioelectrical impedance analysis (BIA), and assessment of cardiorespiratory fitness (CRF). This research also employed the My Eating Habits (MEH) questionnaire and the short version of the International Physical Activity Questionnaire (IPAQ-SF). Results: Based on body fat percentage (BF%), nearly one-fifth (19.69%) of participants were classified as obese. According to the body mass index (BMI), over one-third had excess body weight (overweight 24.02%, obesity 10.24%), while 6.7% were underweight. Eating disorders were significantly more prevalent in women (p = 0.0002). A significant relationship was observed between eating disorders and BMI, muscle mass (MM%), skeletal muscle mass (SMM%), body fat (BF%), and visceral fat (VFATL). Higher BMI, BF%, and VFATL were associated with a greater risk of developing eating disorders. Emotional overeating was significantly less common among individuals with normal body weight compared to those who were underweight or overweight. No statistically significant associations were found between students’ physical activity levels and eating habits. However, cardiorespiratory fitness (CRF) was significantly negatively correlated with the presence of eating disorders. Conclusions: Understanding the relationship between components of body composition, eating disorders, physical activity levels, and cardiorespiratory fitness is crucial for designing effective interventions that promote a healthier lifestyle and psychological well-being among university students.

The prevention of chronic diseases, especially metabolic disorders, is based on modification of behavioural risk factors, in particular eating habits and physical activity. Numerous population studies have demonstrated a relationship between regular physical activity and decreased levels of risk factors for CVD (cardiovascular disease), type 2 diabetes and some cancers. Increasing the level of physical activity as part of the programs implemented for disease prevention or health promotion for selected populations requires a behavioural diagnosis, whereby an essential element is the preferred leisure-time activity in terms of the structure of negative health indicators. Evaluation of physical activity under population studies requires a simple, validated and inexpensive tool to be used in medical practice or health promotion. The Minnesota Leisure Time Physical Activity Questionnaire (MLTPAQ) is a tool currently often used and validated with laboratory methods. Standard MLTPAQ allows for assessment of the level of physical activity undertaken in leisure time. The authors present an algorithm for assessing leisure-time physical activity level based on MLTPAQ. The paper also reviews the practical application of the MLTPAQ questionnaire on healthy and patient populations in Poland and other countries by specialists in public health, health promotion and in medical practice.

Carpathian Euroregion gathers the population of 5 countries, including Poland, Slovakia, Hungary and Romania- the European Union members, as well as Ukraine. Young women are statistically less involved in high-intensity physical activity than young men. The objective of this work was to assess the relation between physical activity of young women aged 18-21 years old and BMI and conditioning factors. The study was conducted between 2010 and 2011 among 2339 women. The Minnesota Leisure Time Physical Activity Questionnarie (MLTPAQ) was applied. It results from the study that 74,2% of young women is considered to have the proper BMI rate (18,5-24,9). As many as 16,2% is considered underweight and almost 10% have higher BMI rate and are overweight. More than one third of respondents did not gain the level of physical activity of 1000 kcal/week, and that is the minimum recommended amount of leisure physical activity time per week. In case of women with low level of physical activity (<1000 kcal), as many as 52% of week activity considered low-intensity activity EEPAlight. The character of changes of the BMI index with reference to the level of physical activity is very similar in the women from towns/cities and the women from villages. An increase of BMI along with the total physical activity was related among all to the increase of free fat mass FFM despite of the level of physical.
