[ effect of pour-weeks aerobic exercise with moderate intensity on Hs-CRP, IL-10, and BDNF in women with syndrome metabolic with the age of 50-65 years old]

Background: the aim of this research was to investigate the effect of four weeks aerobic exercise with moderate intensity on hs-CRP, L10, and BDNF in women with syndrome metabolic with the age of 50-65 years old

Methods: 24 women with metabolic syndrome [MetS] took part voluntarily and divided in two-group MetS exercise [ME], MetS control [MC]. ME group participated in an aerobic exercise training [AT] program [4 weeks], three session per week, each session contained three performing parts and two rest part. Also, blood samples were conducted before and after training for evaluating levels of hs-CRP, IL-10, BDNF. Data were analyzed using Pried-sample T-Test, and Independent samples T-Test

Results: IL-10, BDNF after four-weeks aerobic exercise significantly increased [P<0.05] also hs-CRP levels had no significantly differences. Hs-CRP, IL-10, BDNF after three months in control group did not significantly changed [P>0.05]

Conclusion: these findings indicate four-weeks aerobic exercises induce to increase IL-10 level and did not change hs-CRP level. And BDNF's may increase relative to nil0 level

[Effect of music on athlete metabolic responses during incremental exercise]

The purpose of this study was to evaluate the effects of music on metabolic responses during incremental exercise in male athletes. In this quasi- experimental study with cross- over design, Ten male athletes [age: 19.76 +/- 0.97 years, height: 176 +/- 6.72 cm, Weight: 68.5 +/- 7 5.95 kg] were voluntarily selected and performed Bruce protocol with fast rhythm music condition until exhaustion, with 72 hours interwal between two days of test. Metabolic factors had assessed in 3, 6, 9 and 12 minutes. Data were analyzed by paired t-test with significant level of <0.05. Listening to fast rhythm music during incremental exercise caused significant increase in respiratory rate exchange, Vco[2], ventilation and breathe rate per minute and significant decrease in perception of exertion rate [P<0.05] and no significant changes in Vo[2], anaerobic threshold and time to exhaustion. The study revealed that listening to fast rhythm music decreases perception of exertion, and also, metabolic system tends to be more involved in anaerobic metabolism during incremental exercise

[Changes of plasma leptin and adiponectin levels in response to combined endurance and resistance training in sedentary postmenopausal women]

Leptin and adiponectin, both as adipose tissue-derived adipocytokines, play a substantial role in the pathogenesis and complications of obesity. This study was performed to examine the effects of combined endurance and resistance training on plasma leptin and adiponectin levels and insulin resistance index [HOMA-IR] in sedentary postmenopausal women. 16 sedentary postmenopausal obese women in two experimental and control groups participated in 10 weeks of concurrent training including resistive [40-60% of 1 repetition maximum] and swimming endurance training [50-60% of maximal heart rate], three days per week. Plasma leptin and adiponectin levels, HOMA-IR and anthropometric indices were measured before and 48 hours after the last training session. Concurrent training did not significantly change plasma leptin level, but caused a significant increased in adiponectin concentration [P=0.001]. Hence, HOMA-IR and all of anthropometric indices improved following 10 weeks of combined training [P<0.05]. Pearson correlation showed a significant correlation between the primary level of adiponectin and primary value of waist circumference [P=0.014], but no significant relationship was found between early level of leptin and anthropometric indices and HOMA-IR [P>0.05]. There were not significant correlation between leptin and adiponectin concentrations and changes of anthropometric indices and HOMA-IR [P>0.05]. Combined endurance and resistance training improves adiponectin concentrations, insulin resistance and anthropometric indices. However, these changes may not be in the line with leptin level changes
