Aim: the purpose of This study aimed to investigate the impact of 8 weeks of using three exercise regimens on glucose profiles and fat percentage in women with MS.Methods: This experimental study included 40 females diagnosed with MS (mean age: 34.30 ± 3.50). The participants were randomly assigned to four groups (N=10): aerobic training (AT), resistance training (RT), combined aerobic and resistance training (AT+RT), and control. The RT involved a series of movements using weighted vests (5-10% of body weight) for three days per week. The AT sessions were conducted for two days per week, lasting 10-30 minutes (40-60% of maximum heart rate). The AT+RT group performed exercises five days per week (two days of AT and three days of RT). Data analysis employed two-way ANOVA with repeated measures and Bonferroni's post hoc test. Statistical analysis was conducted using SPSS version 26 software, with a significance level of 0.05.Results: The results revealed no significant differences between groups. However, within-group analyses demonstrated a significant decrease in insulin, cortisol, HbA1C, and HOMA-IR levels compared to baseline in the intervention groups.Conclusions: These findings suggest that exercise interventions have the potential to positively influence metabolic parameters in individuals with MS. Further research is needed to explore optimal exercise protocols and long-term effects in this population.Key words: Multiple sclerosis, body composition, sugar profile

Aim: Taurine is an antioxidant supplement. Therefore, the purpose of this study was to investigate the effect of short-term supplementation of two different dosages of taurine supplement on responses of some salivary antioxidant parameters of young men after an exhaustive aerobic activity. Methodology: Eight healthy non-athlete men (mean ± SD age 21.6 ± 1.7 yrs and VO2 max 62.62 ± 62.2 ml / kg / min) were randomly divided into two categories (3 Vs. 6 Gr/d) in two 7-day periods in the complement of taurine as cross-over, randomized and double-blinded. Saliva samples were collected in three occasions: before and after the supplementation period and immediately after exhaustive aerobic exercise. The subjects started the exhausting aerobic activity on ergometer was performed at 60 RMP and 20 watts, with, 20 watts added to the intensity every minute until the subject got exhausted. Results: The results showed that the SOD, after supplementation (in doses of 6 grams more than the dose of 3 g) and after exercise increased significantly compared with the pre-supplementation in both doeses (p < 0.05). The activity level of POX and DPPH increased with supplementation and activity, but there was no significant difference between the two doses. Conclusion: According to the research findings, it can be concluded that the short-term consumption of taurine supplementation by increasing antioxidant capacity will reduce the negative effects of free radicals as a result of intense aerobic exercise activities.

Abstract
The purpose of this study was to investigate the effect of aerobic exercise with and without BFR on mitochondrial dynamic and mitophagy proteins of human skeletal muscle. In a cross-sectional study, five young men (age: 33.4 ± 2.30 year, weight: 79.64 ± 10.49 kg, BMI: 26.24 ± 2.27kg/cm2) ...

The purpose of this study was to investigate the effect of aerobic exercise with and without BFR on mitochondrial dynamic and mitophagy proteins of human skeletal muscle. In a cross-sectional study, five young men (age: 33.4 ± 2.30 year, weight: 79.64 ± 10.49 kg, BMI: 26.24 ± 2.27kg/cm2) performed two aerobic exercise intervention with BFR (EX+BFR) and without BFR (EX) in two separate days. The aerobic exercise included 5 bouts of 2-min activities, interspersed by 1 min active rest which performed with and without BFR. Western Blot method was used to measure the protein levels of MFN2, DRP1, BCL2 and Parkin of skeletal muscle. Data analysis was performed using T test at a significant level of 0.05. The results of the data analyze showed that both EX+BF and EX significantly increased MFN2 and Parkin and also significantly decreased DRP1 compared to the pre-test (p < 0.05). However, EX+BF resulted in a significant increase protein levels of BCL2 compared to the pre-test (p < 0.05). Also, EX+BF has a significant effect on MFN2, BCL2 and Parkin elevation and DRP1 decrease in compared to EX (p < 0.05). Based on the findings of this study, it seems that aerobic exercise with and without BFR is a strong stimulant for the improvement of mitochondrial dynamics and mitophagy of skeletal muscle.

Objective: The aim of the present study was to investigate the effect of 10-week negative energy balance (NEB) methods on adipocyte size and adiponectin levels in different abdominal fat depots as well as glucose and lipid variables and insulin resistance in high-fat-diet obese male wistar rats. Methodology: Study sample were consisted of sixty-four Wistar male rats (average weight; 194.5±12.6g). Blood samples were collected at 1st, 18th and 28th weeks after an overnight fasting. After first sampling, remaining 56 rats were randomly divided into control (n=16) and high-fat-diet (n=40) groups. After 18 weeks High-fat-diet group randomly divided into high-fat-diet (HFD) and negative energy balance consisted of calorie restriction, exercise training and combination (exercise training with calorie restriction) subgroups. Negative energy balance subgroups underwent an aerobic training (running) with intensity of 70 to 75% of VO2max, %25 calorie restriction and interval of both methods for 10 weeks. Adiponectin Levels and adipocyte size in retroperitoneal and mesenteric fat depots, insulin and glucose levels and lipid profile were measured. HOMA-IR was also calculated. Results: The results of this study indicated that in comparison to high-fat-diet, negative energy balance methods despite consumption of high fat diet, decreased adipocyte size in retroperitoneal and mesenteric fat depots (P<0.05) and insulin resistance index improved in line with decrease of serum concentrations of insulin, glucose and triglyceride in obese male rats (P<0.05). However although lipid profile improved, only triglyceride concentration significantly decreased (P<0.05). From negative energy balance subgroups only combination showed significant increase in adiponectin levels of studied depots compared to high-fat-diet (P>0.05). Conclusion: This study indicated that negative energy balance methods can actually decrease adipocyte size of retroperitoneal and mesenteric fat depots even with simultaneous consumption of high-fat-diet which is largely congruent with improvement in lipid and metabolic profile Results also indicate a superiority of aerobic training in improving the lipid profile compare to other NEB methods.
