| Popis: | Physical exercise is a planned and repeated exercise aiming to maintain and improve one or more aspects of physical condition. Increased sympathetic-adrenal activity and reduction of insulin concentration are the main stimuli of lipolysis during physical activity.The aim of this study was to investigate acute and chronic effects of intensive aerobic training program on lipid profile and antropometric parameters in young healthy soccer players.Fifteen healthy male (soccer players, average age 21.4±3.6) were included in this study. Soccer players had a minimum of 6 months continuous training that consisted of three training sessions per week. They did not smoke, take drugs or drink alcohol during the examination period. A balanced diet (60% carbohydrates, 25% lipids and 15% proteins) was recommended by a nutritionist as a standard diet during the preparations period. This consisted of three repetitions of 20-min running sessions, with two 3-min breaks in-between. Target load was obtained at 120–140 bpm heart rate. Anthropometric estimation comprized determination of body fat % by impendansometer Omron BF306, body height (BH), body weight (BW), waist circumference (WC), waist/hip ratio (WHR) and determination of body mass index (BMI=BW/BH2). Blood samples were taken prior to and 5-10 min after completion of exercise. Biochemical investigation comprized spectrophotometric determination of total cholesterol (TC), triglicerides (TG), HDL-C and low-density lipoprotein cholesterol (LDL-C). There was a significant reduction of body fat content % after 6 months of intensive physical preparation (p |
