Several studies on exercise and its effect on cognitive function in human and animal populations have documented the beneficial impact of regular physical activity on maintenance of good cognitive abilities and satisfactory health-related quality of life well into older age. The aim of the study was to evaluate the effects of long-term regular running on metabolic profile and cognitive function in middle-aged men.A total of 24 regularly exercising, middle-age men (Group A), all being members of the Runners Club, and 22 age-matched sedentary subjects (Group B), as the control group, were enrolled in this study. The control group included 8 non-overweight (BMI=23.5±5.2) individuals (Group C) and 14 overweight/obese (BMI=30.7±1.6) subjects (Group D). Serum lipid profile, glucose and homocysteine concentrations were assessed by routine laboratory methods. Subjects' cognitive function was evaluated based on Trail Making Test (TMT) and Digit Symbol Test (DST) scores.In a majority of runners (Group A), the BMI and the parameters of lipid profile (TC, HDL, LDL, TG, glycerol) were close to those recorded in non-overweight controls (Group C) and, in both groups, results were ideally within the reference ranges for healthy male subjects. However, as compared to the whole control group (Group B), which may be considered as an average population sample of sedentary middle-age men, significant differences were observed in BMI and concentrations of TC and LDL, as well as in the pro-atherogenic biomarkers (TC/HDL, LDL/HDL), which were lower in runners. A similar tendency was found in concentrations of TG (independent cardiovascular risk factor), glycerol and TG/HDL ratio (surrogate measure of insulin resistance), however the differences did not reach the level of significance. The level of homocysteine (pro-atherogenic biomarker) was comparable in all groups, and in most cases, within the reference range for male adults. Results of cognitive function tests did not reveal any significant between-group differences. The TMT score was found to be correlated positively (r=0.492, p<0.05), whereas DST score was correlated negatively (r=-0.549, p<0.005), with age. The DST performance, as evaluated in the group of runners (Group A), appeared to be strongly dependent (r=0.809, p<0.005) on the educational level of the subject.These data provided evidence of beneficial effects of a long-term regular endurance running exercise on lipid profile and cardiovascular health in middle-aged men. However, we failed to confirm the findings of a favorable impact of regular physical activity on improvement in cognitive abilities.

Purpose. The aim of the present investigations was to determine the effects of aqua aerobics on body weight and composition, lipid profile, and selected blood count parameters in middle-aged sedentary females. Methods. Twenty-one women were randomly assigned to an experimental group (age 56.20 ± 2.57 years, height 162.80 ± 4.76 cm, weight 74.03 ± 3.84 kg) that participated in aqua aerobics classes three times a week for three months and a control group (mean age 56.44 ± 3.28 years, height 165.00 ± 3.91 cm, weight 70.01 ± 11.36 kg) not involved in any kind of targeted exercise. The aqua aerobics classes were tailored to suit the age and abilities of the participants, with workout intensity controlled and maintained at approximately 128-137 bpm. Results. Significant differences between the experimental and control groups were found for body weight, total body water, fat-free mass, and skeletal muscle mass. A significant increase in post-intervention hemoglobin and erythrocyte counts was observed in the experimental group. Conclusions. Future studies should determine the intensity of physical activity with the most beneficial effect on blood variables in middle-aged and older individuals.

Whole-body vibration (WBV) exercise is an alternative, popular and easy exercise that can be followed by general public. Therefore, the aim of the present study was to investigate the influence of acute and chronic WBV exercise on health-related parameters. Twenty-eight women were allocated into a control group (n=11, mean ±SEM: age, 43.5 ±1.5 yr; body mass, 66.1 ±3.1 kg; height, 160.6 ±1.5 cm) and a vibration group (n=17, mean ±SEM: age, 44.0 ±1.0 yr; body mass, 67.1 ±2.2 kg; height, 162.5 ±1.5 cm). After baseline assessments, participants of the experimental group performed WBV training 3 times/week for 8 weeks. Before and after the chronic WBV exercise, the participants of the vibration group performed one session of acute WBV exercise. Blood chemistry measurements (hematology, creatine kinase, lactate dehydrogenase, aspartate aminotransferase, alanine aminotransferase, C-reactive protein, glucose, insulin, triacylglycerols, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, apolipoprotein A1, apolipoprotein B and lipoprotein, thiobarbituric-acid reactive substances, protein carbonyls, total antioxidant capacity, uric acid, albumin and bilirubin) were assessed pre-exercise and post-exercise at the first and eighth week of WBV exercise in both control and vibration groups. The results failed to support any effect of both acute and chronic WBV exercise on biochemical health-related parameters. However, it seems that WBV exercise is a safe way of training without a negative impact on muscle and liver functionality.

Background: The purpose of the study was to find out the effect of training on selected morphological, physiological and biochemical variables in soccer players under 19 years of age.Material/Methods: A total of 30 Indian male soccer players under 19 years of age (age: 16.00-18.99 yr) volunteered for this study. The training sessions were divided into 2 phases (i) Preparatory Phase (PP, 8 weeks) and (ii) Competitive Phase (CP, 4 weeks). The training programme consisted of aerobic, anaerobic and skill development, and was completed 4 hrs/day; 5 days/week. Selected morphological, physiological and biochemical variables were measured at zero level (baseline data, BD) and at the end of PP and CP.Results: A significant increase (P<0.05) in lean body mass, VO2max, anaerobic power, grip and back strength, urea and uric acid levels; and a decrease (P<0.05) in percentage of body fat, haemoglobin, total cholesterol, and LDL-C levels have been noted in PP and CP when compared to BD. However, no significant change was noted in stature, body mass, maximal heart rate, triglyceride and HDL-C levels of the players after the training.Conclusions: This study would provide useful information for training and selection of soccer players of under-19-year-old groups.

The world’s population is aging. Aquatic exercises can improve the physical function in humans and raise the quality of their lives in middle and older age. The study aimed to determine the effect of aqua aerobics on the selected somatic, physiological and aerobic capacity parameters in postmenopausal women. 11 purposively selected women that were confirmed overweight or obese by 20% and had Body Mass Index of 30±5 (the first stage of obesity) took part in aqua aerobics classes three times a week for 14 weeks. Their mean age was 56.18±3.19 years and mean height was 166.5±7.41 cm. The value of LBM and muscle mass (p=0.04 in both cases) were statistically significantly higher at study end compared with their baseline values, likewise haemoglobin concentration (p=0.001), haematocrit (p=0.03) and blood cell count (p=0.01), whereas BMI (p=0.02) and percentage body fat (p=0.04) were significantly lower. The lactate analysis revealed significant changes in LAmax (p=0.04), LAres9' (p=0.02), DeltaLAmax-LAsp (p=0.02) and DeltaLAres9’-LAres3’ (p=0,0004). After 14 weeks of aqua aerobic workout, significant changes were noted in the selected somatic, morphological and aerobic capacity parameters in postmenopausal women, but the differences between the lipid profiles were insignificant.
