مقایسه تاثیر فعالیت هوازی حاد با شدت کم و متوسط بر نیمرخ لیپیدی مردان

Background and objectives: the purpose of this study was to compare two intensities of acute aerobic exercise on lipid profiles in overweight elderly men.subjects and methods: fifteen overweight elderly men (mean ± sd; age 66.2 ± 3.6 years, height 176.3 ± 5.7 cm, weight 90.58 ± 4.7 kg) participated in the study. in the first session, anthropometric measurements, body composition, and maximum oxygen uptake (vo2peak) was measured in all subjects. in the next sessions, subjects completed two acute aerobic exercises on separate days in a crossover design. the two exercise trials performed at intensity of 45% and 65% vo2peak after fasting for at least 10 hours and for 30 minutes per session treadmill. blood samples before and after exercise were collected for measuring total cholesterol, triglyceride, hdl-c and ldl-c.results: the results showed that triglycerides, ldl-c and total cholesterol levels were significantly decreased after moderate intensity of acute aerobic exercise (p < 0.05). also hdl-c levels was significantly increased after moderate intensity of acute aerobic exercise (p < 0.05). no significant changes were observed in triglycerides, hdl-c, ldl-c and total cholesterol levels after low intensity of acute aerobic exercise (p > 0.05).conclusion: according to the present results, we can conclude that acute aerobic exercise at moderate intensity compared with low intensity improves the lipid profile in overweight elderly men.
