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

Hypertension similar to dyslipidemia is most important cardiovascular diseases that exercise training can have a preventive and therapeutic effect on them. The effect of combined exercise training as an effective method is one of the new ways to combat hypertension and cardiovascular health. The purpose of this study was to investigate the effect of combined exercises training on cardiovascular inflammatory markers and blood pressure in hypertensive men.In this study that designed with pre-post tests with control group, 9 men (47.33±4.5 years; body mass index 33.18±5.27 kg/m2) as combined training group [COT] and 9 as control group [CON] (48.44±3.20 years; body mass index 30.51±5.35 kg/m2) were randomly selected from volunteers. Combined training (aerobic and resistance) that performed in 16 weeks consisted of 4 sessions per week (2 sessions of aerobic and dynamic resistance training, respectively). Aerobic training with 40-65% maximal oxygen uptake (70-80 minutes) and dynamic resistance training with 55% maximum repetition (70-80 minutes) were performed. Results of ANCOVA test showed that systolic and diastolic blood pressure, galactin-3 and endothelin-1 plasma levels were significantly decreased in the post exercise training group as well as in the control group (p<0.05). In lipid profile, we observed significant decrease in total cholesterol (TChol) in combined exercise training group (p<0.05). It can be concluded that, the results showed that the combination of aerobic and resistance training, in addition to lowering blood pressure and improvement of dyslipidemia in men with hypertension, led to a decrease in biomarkers affecting vascular inflammation and heart failure.

Aim: The purpose of present study was to compare the effect of two volumes six- and eight-week of concurrent training on physical fitness factors, cortisol, and high-sensitivity C-reactive protein (hs-CRP) level changes in adolescent soccer players. Method: Twenty players (age: 15 ± 0.91 years; weight: 61.10 ± 10.07 kg; soccer experience: at least 5 years) randomly divided into 6-week or 8-week group (n=10). The training protocol had two phases including general (three weeks) and specific in three days a week for 90 min. The type and intensity were same for both groups and only the volume was different between them. Aerobic power (1609 m), speed (60 m), muscular endurance (push up and sit up), and fasted venous blood samples (cortisol and hs-CRP) were collected before and after training period at 8-8:45 P.M and 8-8:30 A.M, respectively. Results: The values of VO2max, speed, push up, and sit up were improved compared to pre-training values in both groups. Eight-week volume was more effective regarding the reduction of cortisol (%16.77; P=0.033), but the speed of six-week group was improved (%5.27) with a large effect size (r = -0.11). With respect to other variables, there was no significant difference between the two groups. Conclusion: Gradual increase in intensity of conditioning training within eight weeks compared to the same increase within six weeks lead to more effective reduction in serum cortisol of adolescent soccer players, but in relation to hs-CRP levels and improve in VO2max, speed and muscular endurance, it has no more advantage.

Objective: The aim of this study was to investigate the effect of aerobic-resistance training on visceral adipose tissue, serum omentin-1 and insulin resistance in ovariectomized (OVX) rats. Methodology: Fifty Female Wistar rats (weight, 180±5g) were divided accidental and according body weight into five groups: SHAM (n=20) and OVX (n=30) groups. OVX rats were subdivided into 2 Ovx+sedentary (Sedentary; n=20) groups and one aerobic-resistance training (Ovx+Exe; n=10) group. Two weeks after surgery, one group of OVX rats and one group of SHAM rats were sacrificed and omentin-1, insulin resistance and visceral fat were measured. The other OVX rats were randomly divided into the following subgroups: 1) OVX and sedentary (Sedentary); 2) OVX and Exercise (Ovx+Exe). The exercise consisted of 8 weeks of aerobic-resistance exercise (3 days/week, 20 m/min, 60 min/day, 10% slope, Load; 3% body weight, attached to tail), three days a week. After complete anesthesia, the abdominal cavity was rapidly opened and blood samples were collected. All intraabdominal fat were dissected out and weighed immediately. Omentin-1 was measured by rat omentin ELISA kit. HOMA-IR was used to estimate the insulin resistance. Results: There was no significant differences between weights means all groups. After two weeks of surgery, there was no significant difference between visceral fat, omentin-1 and HOMA-IR in SHAM2 compared to OVX2. After eight weeks, combined aerobic-resistance training in Ovx+Exe significantly decreased visceral fat gain induced via ovariectomy by 21/4% compared to the level observed in Sedentary; whereas, visceral fat significantly increased by 92.5% in OVX2 compared to SHAM2 (p<0.05). Omentin-1 increased in Ovx+Exe compared to Sedentary and SHAM, by56/5% and51/6%, respectively; whereas it was significantly decreased by3/1% in Sedentary compared to SHAM (p<0.05). HOMA-IR induced via ovariectomy significantly decreased by74.7% in Ovx+Exe compared to Sedentary; whereas, it significantly increased by 193.7% in OVX2 compared to SHAM2 (p<0/05). Also, HOMA-IR decreased in Ovx+Exe compared to SHAM2, but it was n ́t significant. Conclusion: 8 week aerobic-resistance training successfully decreased visceral fat and insulin resistance via increasing omentin-1. So, it seems that 8-week aerobic-resistance training with 70-85% Vo2max is suitable for controlling body weight gain, decreasing visceral fat and insulin resistance and increasing omentin-1 in menopause period.

Abstract
Aim: The aim of this study was to determine the effect of reduced muscle glycogen on maximal fat oxidation (MFO) and the exercise intensity at which maximal fat oxidation was occure (Fatmax) in untrained men.
Method: Eight healthy untrained males (age: 22.2±1; body mass index: 21.9±1.5 kg/m2; percent body fat (%): 15.1±1; VO2Peak: 2.82±0.41 L.min-1) participated in two studies carried out on separate days at least one week apart. Each subject in the fasting state (7:00 AM) performed graded exercise test with 3 min stages on a cycle ergometer to exhaustion, on two separate occasions randomly, in a normal glycogen state and under conditions of reduced muscle glycogen content. On one occasion, the day before the graded exercise test, subjects came to the laboratory at 18:00 pm to perform an exhaustive muscle glycogen lowering exercise. Indirect calorimetry was performed to determine oxygen consumption (VO2) and carbon dioxide production (VCO2) at during gradedexercise. Substrate oxidation, MFO and Fatmax was determined during graded exercise test, by use of the stoichiometric equations. The student’s t-test was used to analyze the variables.
Results: MFO in the lowering muscle glycogen (0.54±0.08 g.min-1) was significantly higher than in the normal muscle glycogen status (0.36±0.04 g. min-1) (P

Abstract
Aim: Brain derived neurotrophic factor (BDNF) is an important factor affecting cognitive function which has recently interested a bulk trend of effort in the health context. In spite of a good body of evidence reported concern to positive association between aerobic fitness, cognitive function and serum BDNF, there is no enough information about the effect of aerobic training and also detraining period on memory function and circulatory BDNF in middle aged individuals.
Method: Twenty one middle aged males (age: 58.08±5.99, weight: 75.79±12.13 kg, BMI: 25.78±2.76 kg.m-2) randomized in two groups including aerobic exercise (Ex, n=11) and control (Con, N=10). Ex subjects participated in six weeks of endurance exercise sessions, 3 sessions/week by the intensity of 60-70% of HRR for 25 to 40 min in each min. Midterm and Short term memory tests were conducted and also blood samples were taken in three occasions including pretest, after six weeks of training and after the following six weeks of detraining period. Data were analyzed using independent t test, ANOVA and ANCOVA repeated measures.
Results: Six weeks of aerobic training in Ex group significantly increased basal serum BDNF level, and also short term and midterm memory function (P
