پاسخ‌های همودینامیک پس از فعالیت‌های ورزشی مقاومتی، هوازی و ترکیبی در مردان سالم تمرین نکرده دارای اضافه‌ وزن

Introduction: After resistance and aerobic training session are decreased mean resting blood pressure. Therefore is expected that concurrent training session had additive effects on hypotension. The aim of this study was to investigate hemodynamic responses after aerobic training session (ATS), strength training session (STS), and concurrent training session (CTS) in untrained, overweight young men. Methods: Twelve healthy men (age: 25 ± 3.3 years, weight: 87.21 ± 2.1 kg, body mass index: 28.02 ± 1.4 kg.m-2) performed STS (3 sets, 10 repetitions at 80% 1RM for 8 exercise, including upper and lower limbs), ATS (50 minutes of running on treadmill exercise at 65% Heart rate reserve), and CTS (2 sets, 10 repetition at 65% 1RM for 6 exercise among those which composed the STS, plus 25 minutes of running on treadmill exercise at 65% Heart rate reserve) with 72 hours interval in counterbalanced crossover design. Blood pressure, heart rate and rate pressure product were measured before, and after the exercise. Results: Systolic blood pressure in ATS was significantly lower than STS during 90 minutes after the exercise (p<0.05), and comparison to CTS the decrease was found significantly only at 15 minute (p<0.05). Although No difference was observed for diastolic blood pressure at between trials and any trial at any time. Heart rate in ATS was significantly lower than STS and CTS (p<0.05). Rate pressure product in STS was significantly upper than ATS and CTS (p<0.05). Conclusion: The results showed that CTS induced hypotension similar to ATS but it had additive effects compare to STS.
