Study aim: The purpose was to assess dietary intake of energy and selected nutrients and plasma lipid profile in young women and men with different levels of physical activity. Material and methods: The research included a total of 116 female and male students at the University of Physical Education who differed in their levels of physical activity. Analysis of the diets was based on 24-hour dietary interviews collected over 4 days prior to blood collection. Concentrations of total cholesterol (TC), HDL cholesterol (HDL-C), and triacylglycerol (TG) were measured in venous blood. In addition, the concentration of LDL cholesterol (LDL-C) and the ratios of TC / HDL-C and LDL-C/HDL-C were calculated. Results: Women, regardless of their physical activity levels, were characterized by a significantly higher concentration of total cholesterol in plasma (4.8 and 4.5 mmol/L, respectively - in training participants; 4.7 and 4.3 mmol/L, respectively - in non-training participants), although their dietary intake of cholesterol was significantly lower in comparison with the corresponding groups of men (282.0 and 484.7 mg, respectively - in training participants; 252.6 and 400.2 mg, respectively - in non-training participants). A trend toward a worse lipid profile of training women and men compared with the corresponding groups of non-training participants was also observed. Conclusions: Increased physical activity in the groups of training women and men was not a sufficient stimulus to induce positive changes in their lipid profiles. Nor can it be excluded that the observed differences were the result of diet, as dietary intake of cholesterol in the groups of training women and men was higher compared with the corresponding groups of non-training participants.

Study aim: To evaluate the relationships between circulating adiponectin and FFA, and other biochemical variables (glycerol, glucose and insulin) in young, healthy non-obese men and women.Material and methods: A group of 53 male and 54 female students participated in the study. The following compounds were determined in plasma: free fatty acids (FFA), glucose and glycerol (colorimetrically), and insulin and adiponectin (by immunoassay). Insulin resistance index (HOMA-IR) was calculated from fasting insulin and glucose concentrations.Results: Mean plasma glucose was slightly lower (p<0.01), and plasma insulin and HOMA-IR markedly higher (p<0.01 - 0.001) in female than in male subjects. Percent body fat was positively correlated with plasma FFA in both groups (p<0.01), but with plasma glycerol (p<0.001) in female students only. Plasma adiponectin was negatively correlated with percent body fat (p<0.02), plasma glycerol (p<0.001) and FFA (p<0.05) in female subjects only.Conclusions: Gender-related differences in body fat may affect the relationship between adiponectin and indices of lipid metabolism.

Study aim: To assess the effects of gender, age and engagement in physical activities of elderly subjects on their plasma lipid profiles.Material and methods: Four groups of subjects, n = 11 each, participated in the study: young men (YM) and women (YW), aged 25 - 32 years, and sedentary, elderly men (EM) and women (EW), aged 58 - 66 years; additionally, a group of 7 women (AW), aged 60 - 65 years, who trained twice weekly (45-min sessions) for 8 months, was studied. The following concentrations of lipids in plasma were recorded: triacylglycerols (TG), total cholesterol (TC) and its fractions: HDLC and LDLC (computed), as well as the TC/HDLC ratio.Results: Lipid profiles were, generally, less favourable in elderly than in younger subjects, high HDLC values noted in active, elderly women being an exception. In elderly subjects, men's profiles were closer to those of younger subjects than in elderly women and differed significantly (p<0.001) lower for TC and LDLC compared with EW group. Triacylglycerols were within normal limits in all groups except EW; LDLC values were mostly abnormally high, the percentages of subjects having normal values ranging from 0 (YM and EW) to 27% (YW).Conclusions: The age-dependent worsening of lipid profiles increased the risk of cardiovascular diseases in sedentary elderly subjects. On the other hand, the beneficial effects of motor activities on lipid profile observed in elderly women evidence the indispensability recommending of physical exercises to the elderly.

Study aim: To assess possible effects of gender and of the level of motor activity on the deficiencies of selected vitamins and minerals in young subjects.Material and methods: Four groups of physical education (PE) students (n = 15 each) were studied: sedentary men (SM) and women (SF), and physically active men (AM) and women (AF) engaged in endurance sports, all aged 18 - 24 years, were studied. Somatic measurements included body height and mass, and body fat content (by Durnin's method, from 4 skinfolds), the biochemical ones included concentrations of retinol, α-tocopherol, copper, zinc and iron in plasma.Results: Men had significantly higher retinol (p<0.05) and iron (p<0.01) levels than women. The AM and SF groups had significantly (p<0.05 - 0.01) higher plasma levels of copper and zinc than Group SM. Group AF had lower zinc levels than Groups AM and SF, that latter group having lower α-tocopherol compared with Group SM.Conclusions: Inasmuch the observed differences could be due to the respective intakes, the effect of motor activity and the associated increased elimination of minerals could not be ruled out.
