The lifestyle of children is most affected by the family, which is defined as a basic social community based on the common life of a close circle of blood relatives, usually parents and children, in which biological-reproductive, economic and education functions are combined. The purpose of the research is to confirm the impact of the educational level of parents on the lifestyle of their children before and during the COVID-19 pandemic. The research included 110 students of both genders from SHMT “Mehmet Isai” and SHMAT “Arbëria” in Gjilan divided into two groups of 55 students, according to the educational level of their parents. The lifestyle survey included 8 questions on physical activity, daily cigarette consumption, alcohol, drug use, eating habits and sleep before and during COVID -19 pandemic. To verify the difference between the groups, the Chi-square test (χ² test) was applied. Survey analysis shows that children of parents with higher educational level have more knowledge about the role of physical activity and spend more time on physical activity, consume less cigarettes and alcohol and more regular eating and sleeping habits at the level p<0.00. We can conclude that the educational level of the parents has a significant impact on the motivation of children to engage in physical activity, reducing the consumption of cigarettes and alcohol, for sleep and regular nutrition.

The purpose of this research is to determine the effects of a specialised two-month fitness programme with strength exercises on the body composition and aerobic endurance in recreational women. The research included a group of women aged 18–35 who had not previously been engaged in recreational exercises in fitness centres. The sample included 50 women who exercised at the Fivestar fitness centre in Gjilan, and who underwent the abovementioned programme. The composition of the body was evaluated using a Tanita BC-601 device and the bioelectrical impedance analysis (BIA), which was conducted as a reference method in the research related to the analysis of body composition. For this research, the following variables of body composition and aerobic endurance were applied: body height (BH), body weight (BW), body mass index (BMI), body fat percentage (BFP), muscle mass (TBM), bone mass or density (BMD), calorie expenditure (DCI), body vitality (BMR), body water intake (TBW), visceral fat intake (AVF), and the Rockport fitness test for aerobic endurance (ROFT). For the dependent group, the T-test analysis was applied through statistical methods. The results obtained after statistical processing showed that, in relation to the two-month programme three times a week (24 trainings), physical exercises in the fitness can affect the reduction of subcutaneous adipose tissue, and thus reduce the risk of various cardiovascular diseases. In addition to reducing fat mass with strength exercises in the fitness, there was also an improvement in aerobic endurance. This shows that, besides aerobic exercise, weight training should be applied to increase aerobic capacity.
