The aim of the current study was investigate the effect of single session of aerobic interval exercise on serum Spexin levels. Methods: Eleven active young men (aged 24±3.63 years, BMI 22.98±2 kg/m2) volunteered for this study. Acute exercise protocol comprising 2 series of 6×10 s sprinting cycling with maximal effort and 10 min active rest (cycling with intensity 65%–75% HRmax). Blood samples were obtained at fasting state, pre-exercise (30 min after breakfast ~365 kcal), immediately after, and 15, 30, and 45 min after exercise. The repeated measures of ANOVA and Bonferroni post-hoc test used to evaluate changes of parameters in the different times. The relationship between variables was assessed using the Pearson correlation coefficient. Results: Despite the changing levels of some metabolites such as glucose, insulin, lactate, TG and LDL-C in this study, spexin levels did not change significantly in any time courses of this study (p>0.05). At fasting state and post-exercise, spexin levels not correlated with other metabolites (p>0.05) but in 30 minutes after breakfast (pre-exercise) negatively correlated with TG (r= -0.645, p=0.032) and during the recovery period, positively correlated with HDL-C (r= +0.357, p=0.041) and negatively correlated with insulin (r= -0.672, p=0.023). Conclusion: It seems that acute exercise-induced negative energy balance in this study may not be sufficient to induce changes in Spexin serum levels.Abstract<br />Aim: Spexin is a novel peptide which plays a role in the regulation of feeding behavior, body weight, energy metabolism, and long-chain fatty acid uptake into adipocytes.

Although swimming performance improvement in 25<br />m front crawl due to strength training was noticeable but these current results do not clarify that these training<br />programs can enhance swimming performance and propulsive force.https://joeppa.sbu.ac.ir/article_98894_98e28f75b7ddc8e02b69cbe49f8d3b24.pdfShahid Beheshti UniversityJournal of Sport and Exercise Physiology2676-371010220171122The effects of eight weeks resistance training and low calorie diet on body composition and relaxin of postmenopausal womenThe effects of eight weeks resistance training and low calorie diet on body composition and relaxin of postmenopausal women991069890010.48308/joeppa.2017.98900FAMohammad HosseinRezvaniJournal Article20160612Aim: The aim of this study is to evaluate the effects of resistance training and low calorie diet on body composition relaxin serum level of postmenopausal women.<br />Methods:In this research 20 post-menopausal women were purposefully selected and randomly divided into two groups (experimental group, n = 11 and control group = 9), the experimental group training for 8 weeks and every week 2 days with the intensity of 20-30% 1RM1, the control group continued their activities during a period of 2 month.<br />Body composition's factors by Inbody device and relaxin serum level with China's kit was measured in the fasting state, in two stages, one week before the start of the training program and 48 hours after the last training session in the eighth weeks was carried out.<br />The covariance and Pearson correlation test analysis were used for data analysis, level of significance was considered by SPSS 18 )p≤0/05.(<br />Results:The results showed that eight weeks of resistance training and low-calorie diet significantly reduced total cholesterol levels, triglycerides, LDL, relaxin and an increase in HDL values before the intervention.<br />Also body weight, fat mass, fat percent, lean body mass and BMI2 of the experimental group was significantly decreased, while the decrease of related indicators of abdominal obesity (waist size, hip and WHR) statistically is not significant, and also there were no significant relationship between relaxin serum levels and the components of body composition, and the relationship between relaxin serum levels and blood lipids in cholesterol serum level and LDL was significant.<br />Conclusion: Therefore decreased of relaxin serum levels induced by caloric restriction combined with resistance training can be effective in reducing the symptoms of menopause and affect them.Aim: The aim of this study is to evaluate the effects of resistance training and low calorie diet on body composition relaxin serum level of postmenopausal women.<br />Methods:In this research 20 post-menopausal women were purposefully selected and randomly divided into two groups (experimental group, n = 11 and control group = 9), the experimental group training for 8 weeks and every week 2 days with the intensity of 20-30% 1RM1, the control group continued their activities during a period of 2 month.<br />Body composition's factors by Inbody device and relaxin serum level with China's kit was measured in the fasting state, in two stages, one week before the start of the training program and 48 hours after the last training session in the eighth weeks was carried out.<br />The covariance and Pearson correlation test analysis were used for data analysis, level of significance was considered by SPSS 18 )p≤0/05.(<br />Results:The results showed that eight weeks of resistance training and low-calorie diet significantly reduced total cholesterol levels, triglycerides, LDL, relaxin and an increase in HDL values before the intervention.<br />Also body weight, fat mass, fat percent, lean body mass and BMI2 of the experimental group was significantly decreased, while the decrease of related indicators of abdominal obesity (waist size, hip and WHR) statistically is not significant, and also there were no significant relationship between relaxin serum levels and the components of body composition, and the relationship between relaxin serum levels and blood lipids in cholesterol serum level and LDL was significant.<br />Conclusion: Therefore decreased of relaxin serum levels induced by caloric restriction combined with resistance training can be effective in reducing the symptoms of menopause and affect them.https://joeppa.sbu.ac.ir/article_98900_cf5efca1391d09dee4b93cf5f788a7ab.pdf
