Evidence of the role of ANGPTL3, a liver-secreted glycoprotein, in serum lipid turnover, led us to hypothesize that this protein may be involved in modification of the lipid profile induced by exercise-training. Given the lack of data regarding this issue, the main goal of the present study was to investigate the effects of regular participation in a recreational physical activity program on serum ANGPTL3 and selected lipid profile measures in young, apparently healthy female and male adults. We compared serum ANGPTL3, lipid profile measures, common lipid ratios, the Atherogenic Index of Plasma (AIP) and glucose in fasting blood samples derived from 22 active physical education students including active females (AF, N=6) and males (AM, N=16) with samples from 28 relatively sedentary agematched peers, including female (SF, N=9) and male (SM, N=19) individuals not involved in any regular physical conditioning program. Despite high inter-individual variability of serum ANGPTL3, there was a general tendency toward higher serum ANGPTL3 and HDL-C in women compared to men, but without significant differences related to their physical activity status. Based on both routine lipid profile measures and lipid ratios, all participants had normal lipid profiles, normal glycemia, as well as favorable anthropometric indices not suggesting increased cardiometabolic risk. However, lower levels of the TG/HDL-C ratio and AIP in physically active compared to relatively sedentary participants, reflecting the predominance of large, buoyant LDL particles, strongly support the view of beneficial healthpromoting effects of regular participation in recreational sport activities.
Introduction. There are currently no studies published on the relationship between participation in international sports events and physical activity of the fans. This inspired the authors to examine this subject. The aim of the study was to estimate the level of physical activity of Polish national teams' supporters of selected sports disciplines. Material and methods. The study was conducted on randomly selected group of fans during the Polish national level football, basketball and volleyball games. The study used the diagnostic survey method with a questionnaire of the authors' own design. In this report there were questions concerning physical activity modelled on the International Physical Activity Questionnaire. Results. Physical activity is usually practised by fans of basketball and football who are 19-35 years old. Fans who are not physically active are mainly the fans of volleyball and football who are 36-55 years old. A significant correlation was noted between fans' sex and the willingness to practice sport (p=0.016). 58% of women and 72% of men declared that they practice some recreational physical activities. The most active were the basketball fans; the least active were the volleyball fans. The greatest diversity in terms of physical activity depending on participants' sex was revealed among the fans at international football games. Additionally, a significant correlation was noted between fans' age and their willingness to practice sports in their free time (p<0.001). Conclusions. The majority of fans at international sports events are physically active. In the research groups analysed the weekly volume of physical activity varied significantly. The basketball fans spent the greatest amount of time on physical activity and the volleyball fans the lowest. The average frequency of physical activity was the same in all groups.
