The purpose of this study was to determine the effect of aerobic exercise on obese women. The research design used was a pretest-posttest two treatment design. The subjects involved in this study were 22 women divided into 2 groups, including the aerobic exercise group and the zumba group. This study was conducted 3 times a week for 12 weeks with 65-85% intensity of the maximum pulse rate. Menstrual cycle data were obtained using the interview technique and menstrual questionnaire. The results of this study indicated that aerobic exercise and zumba did not affect the menstrual cycle. Although the study data showed no increase or decrease in menstrual cycles after endurance training, overall subjects experienced positive psychological improvements and decreased menstrual pain.This study concludes that aerobic exercise is good to do because it does not affect the menstrual cycle.

Abstract Objectives The number of studies examining the circulating level change of betatrophin and cartonectin in metabolic syndrome applying different loads of exercise is limited. The purpose of the present study was to investigate how different loads of exercises regulate the betatrophin and cartonectin levels in metabolic syndrome induced rats. Methods A total of 24 Wistar-Albino male rats were used in the study. Rats were divided into four groups as follows; G1: control group (fed with standard diet and tap water), G2: metabolic syndrome group (without exercise application), G3: metabolic syndrome + aerobic exercise group (aerobic exercise applied), G4: metabolic syndrome + anaerobic exercise group (anaerobic exercise applied). Betatrophin and Cartonectin levels were determined by ELISA method in serum samples. Results There was a statistically significant difference in betatrophin levels between the groups and this differentiation was caused by G2 (p <0.05). Cartonectin levels were not significantly different between groups (p> 0.05). Conclusions It can be concluded that anaerobic exercises have more positive effects on glucose balance in metabolic syndrome than aerobic exercises, and by regulating betatrophin levels, anaerobic exercises indicate this effect.

ObjectiveThe menstrual cycle represents a continuous state of change in terms of female sex steroid environment. Progesterone is linked to increased fat storage while estrogen exerts anti-lipogenic effects. This study investigated variations in the potent lipogenic factor acylation-stimulating protein (ASP), and examined its association with hormonal and lipid profile alterations across the menstrual cycle.Methods and designNineteen non-obese women with regular menstrual cycles were investigated in a longitudinal study during the follicular, ovulatory, and mid-luteal phases (ML) of the cycle. Fasting ASP, LH, FSH, progesterone, estradiol, insulin, lipid profile, and apoproteins were evaluated during different phases of the cycle.ResultsASP levels changed significantly throughout the menstrual cycle (K-related Friedman test: P=0.013). Interestingly, these changes coincide with variations in progesterone levels across the cycle as no significant change in the ASP levels was seen across the follicular phases of the cycle, followed by a significant increase in the ovulatory phase, which continued to elevate toward the ML. The ASP levels correlated positively with the progesterone levels normally elevated in the ML. No significant correlation was seen between ASP and estrogen or any other measured female hormone. Multiple regression analysis including all measured parameters and body mass index showed that progesterone was the only significant predictor of the ASP levels.ConclusionOur findings suggest that during the menstrual cycle of normal women, the ASP levels coincidentally fluctuate with the progesterone levels, possibly reflecting cooperation between them in fat storage enhancement.

Background: Limited energy intake with physical activity is effective to reduce health problems associated with obesity. It has been shown that PYY3-36 level increased after intense exercise. This study investigated effect of exercise therapy on appetite suppression and weight loss among obese and/or overweight women. Methods: There was a quasi-experimental with a pretest-posttest design, two groups (control-exercise) study. Study population was overweight or obese women with 20-34 years old and body mass index 27-34 kg/m2. 13 women were randomly assigned in 2 groups (exercise group with 8 weeks of aerobic exercise training (n=7) and control group (n=6)). Weight, waist circumference, hip circumference, lipid profile, cortisol and PYY3-36 were measured at baseline and end of the study. Results: In baseline of study, there was no significant difference across the groups in factors mean (P>0.05).In control group, after 8 weeks, there was no significant difference in variables.(P>0.05) However, In exercise group significant decrease was observed in BMI, WHR, PYY3-36, TG, CHOLESTROL(TC) and LDL, compared to control group (P<0.05). Conclusion: Aerobic exercise within the 80% of heart rate reserve is beneficial in lipid profile, appetite management and modified anthropometric factors. These studies demonstrate that a cortisol change is not along with PYY3-36 changes. We suggest the longer exercise training for this purpose.

Introduction: Obesity is a major risk factor for inflammation and cardiovascular diseases. We tried to assess whether 12 weeks of aerobic exercises affect serum resistin level and lipid profile in overweight females or not. Methods: For this purpose, 32 non-trained adult females with the mean age of 38 ± 7 years old and body mass index (BMI) of 32 ± 3 kg/m2 were randomly assigned to aerobic exercise (n=16) and control (n=16) groups. Twelve weeks of aerobic exercise program including 3 sessions weekly at 60-75% of maximum heart rate was considered. Fasting serum resistin level, lipid profile (total cholesterol [TC], low-density lipoprotein [LDL] and high-density lipoprotein [HDL] cholesterol, and triglyceride [TG]), and anthropometric indexes were measured and compared between the two groups before and after training. Results: Serum resistin, lipid profile markers, and anthropometrical indexes were not significantly different at baseline between the two groups (P>0.05). TG, TC, LDL, and serum resistin did not change significantly after the intervention in the exercise group (P>0.05). However, a significant increase in HDL (exercise: 46.3 ± 9.6 vs. 51.4 ± 8.5, P=0.011; control: 45.8 ± 7.9 vs. 46.8 ± 6.9 P=0.326) and a significant decrease in LDL/HDL ratio (exercise: 2.94 ± 0.12 vs. 2.47 ± 0.19, P=0.019; control: 3.14 ± 0.23 vs. 3.18 ± 0.63, P=0.265) were observed after the intervention. Other variables in the control group remained unchanged. Conclusion: Aerobic exercises had no impacts on the inflammatory profile but could improve lipid profile with an emphasis on HDL in adult obese women.

Immunization of female mammals with native zona pellucida (ZP) proteins is known to cause infertility. Since each human ZP protein is now available as a purified recombinant protein, is it possible to compare the immunocontraceptive potential of each ZP protein. A breeding study was conducted in cynomolgus monkeys (Macaca fasicularis) after immunization with recombinant human ZP (rhZP) proteins (ZPA, ZPB, ZPC) separately and in combinations. This study demonstrated that immunization with recombinant human ZPB (rhZPB) protein caused cynomolgus monkeys to become infertile for 9-35 months. A second study was conducted in baboons (Papio cynocephalus), which yielded a similar result. The baboons immunized with rhZPB became infertile for 9 to > 20 months. During the time of maximum antibody titre, some animals experienced disruption of the menstrual cycle, but eventually all of the animals resumed normal menstrual cycles. Control animals and animals immunized with other rhZP proteins all became pregnant before any of the rhZPB-treated animals. This is the first study in which a recombinant ZP protein has consistently induced infertility in a primate without permanent disruption of the normal menstrual cycle.

Low levels of the neurotransmitter serotonin have been associated with the onset of depression. While traditional treatments include antidepressants, physical exercise has emerged as an alternative for patients with depressive disorders. Yet there remains the fundamental question of how exercise is sensed by the brain. The existence of a muscle–brain endocrine loop has been proposed: according to this scenario, exercise modulates metabolization of tryptophan into kynurenine within skeletal muscle, which in turn affects the brain, enhancing resistance to depression. But the breakdown of tryptophan into kynurenine during exercise may also alter serotonin synthesis and help limit depression. In this study, we investigated whether peripheral serotonin might play a role in muscle–brain communication permitting adaptation for endurance training. We first quantified tryptophan metabolites in the blood of 4 trained athletes before and after a long-distance trail race and correlated changes in tryptophan metabolism with physical performance. In parallel, to assess exercise capacity and endurance in trained control and peripheral serotonin–deficient mice, we used a treadmill incremental test. Peripheral serotonin–deficient mice exhibited a significant drop in physical performance despite endurance training. Brain levels of tryptophan metabolites were similar in wild-type and peripheral serotonin–deficient animals, and no products of muscle-induced tryptophan metabolism were found in the plasma or brains of peripheral serotonin–deficient mice. But mass spectrometric analyses revealed a significant decrease in levels of 5-hydroxyindoleacetic acid (5-HIAA), the main serotonin metabolite, in both the soleus and plantaris muscles, demonstrating that metabolization of tryptophan into serotonin in muscles is essential for adaptation to endurance training. In light of these findings, the breakdown of tryptophan into peripheral but not brain serotonin appears to be the rate-limiting step for muscle adaptation to endurance training. The data suggest that there is a peripheral mechanism responsible for the positive effects of exercise, and that muscles are secretory organs with autocrine-paracrine roles in which serotonin has a local effect.

Cardiorespiratory fitness (CRF) is assumed to exert beneficial effects on brain structure and executive control (EC) performance. However, empirical evidence of exercise-induced cognitive enhancement is not conclusive, and the role of CRF in younger adults is not fully understood. Here, we conducted a study in which healthy young adults took part in a moderate aerobic exercise intervention program for 9 weeks (exercise group; n = 48), or control condition of non-aerobic exercise intervention (waitlist control group; n = 72). Before and after the intervention period maximal oxygen uptake (VO2max) as an indicator of CRF, the Flanker task as a measure of EC performance and grey matter volume (GMV), as well as cortical thickness via structural magnetic resonance imaging (MRI), were assessed. Compared to the control group, the CRF (heart rate, p < 0.001; VO2max, p < 0.001) and EC performance (congruent and incongruent reaction time, p = 0.011, p < 0.001) of the exercise group were significantly improved after the 9-week aerobic exercise intervention. Furthermore, GMV changes in the left medial frontal gyrus increased in the exercise group, whereas they were significantly reduced in the control group. Likewise, analysis of cortical morphology revealed that the left lateral occipital cortex (LOC.L) and the left precuneus (PCUN.L) thickness were considerably increased in the exercise group, which was not observed in the control group. The exploration analysis confirmed that CRF improvements are linked to EC improvement and frontal grey matter changes. In summary, our results support the idea that regular endurance exercises are an important determinant for brain health and cognitive performance even in a cohort of younger adults.

The Impact

Abstract Introduction Obesity is associated with hyperestrogenism along with other hormonal abnormalities affecting the menstrual cycle. The most effective and decisive method of obesity treatment is bariatric surgery. The aim of this study was to analyze the impact of bariatric surgery on menstrual cycle, the incidence of menstrual abnormalities, hyperandrogenism manifestation, and contraception use. Materials and Methods It was a cross-sectional study of 515 pre-menopausal women who had undergone bariatric surgery between 1999 and 2017 in a bariatric center. Data was collected via anonymous questionnaire, and the questions covered a 1-year period before the surgery and the last year before questionnaire completion. Results Before the surgery, 38.6% of the patients reported irregular menstruations in comparison with 25.0% after bariatric surgery (RR = 0.65; 95%CI 0.53–0.79). The mean number of menstruations per year did not differ before and after surgery (10.2 ± 3.9 vs 10.4 ± 3.3; p < .45). There were no statistically significant differences in terms of prolonged menstruations, acne, and hirsutism prevalence. A total of 14.4% of patients before surgery reported estrogen-based contraception use in comparison with 15.0% after the surgery (p < .95). There were no significant differences in the frequency of OC use (11.0% before surgery vs 13.6% 12 months after the surgery vs 11.5% at the moment of survey administration; p < 0.46). Conclusion Bariatric surgery improves the regularity of the menstrual cycle in obese women in reproductive age. The lack of any changes in the combined hormonal contraception (CHC) use, especially OC, before and after bariatric surgery may be a result of a possibly low level of contraception counseling.
