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: This study aims to investigate the impact of two training methods, 3/7 and cluster set (CS), on the strength, body composition, and athletic performance of female basketball players. Methods: Twenty-one basketball players (22.23±3.8y; 165.94±6.78cm; 63.30±9.50kg), who had not engaged in resistance training for the past 6 months, were randomly divided into three groups: 3/7, CS, and a control group. The experimental groups followed an eight-week resistance training program (three sessions/week). Pre- and post-training assessments included measurements of body composition, evaluation of maximum strength, and various athletic performance tests such as Repeated Anaerobic Sprint Test (RAST), Repeated-Sprint Ability (RSA), 10-m sprint, T-test agility, countermovement jumps (CMJ), and squat jump (SJ). To determine the significant difference between the groups, a 3 × 2 mixed model ANOVA was performed. Results: The 3/7 group showed significant improvements in full body strength compared to the pre-test and control group. The CS group exhibited significant improvements in lower body strength. Both experimental groups showed significant improvements in CMJ, T-test time and 10-m sprint time compared to the pre-test and control group. In terms of SJ, the 3/7 group showed a significant improvement compared to the pre-test, CS group, and control group. However, no significant effects were observed on RAST, RSA, and body composition among the different protocols. Conclusions: The 3/7 training protocol, with its shorter training time and lower intensity, proves to be an effective method for enhancing maximum strength, speed, agility, and jumping ability in female basketball players while minimizing the risk of injury.

Aim: Adipose tissue, as a metabolically active tissue, plays an important role in increasing inflammatory indices. So, the aim of this study was to investigate the effect of two-week high intensity interval training (HIIT) with thyme extract supplementation on some inflammatory and anthropometric markers in Tabriz city obese and overweight women. Methods: The current research was a semi-experimental study, and its statistical population consisted of overweight and obese women. To investigate CRP, ESR, TNF-α, quality of life, and body composition, 40 people were selected voluntarily with an average age of 33.07 ± 4.79, weight 76.76 ± 5.63, and body profile 29.02 ± 1.74, and were randomly divided into four homogenous groups (10 people in each group): training, supplement, training+supplement group and placebo. HIIT was performed for two weeks with 80-95% of HRR and Azarbaijani thyme was used as a supplement in two times a day. The data was analyzed using analysis of covariance test in the significance level of 0.05. Findings: The results showed that there is a significant difference in CRP (F=15, P=0.0001), TNF-α (F=25.56, P=0.0001), ESR (F=47.7, P=0.0001) , BMI (F = 20.71, P = 0.01) and WHR (F = 10.16, P = 0.01) between groups.. But there was no significant difference in calf circumference (F = 0.56, P = 0.64). Conclusion: Short-term HIIT alone or in combination with thyme reduces inflammation (CRP, ESR and TNF-α) and improve some anthropometric indicies in obese and overweight women.

Aim: Exercise reduces weight and prevents obesity. The aim was to evaluate the effect of eight weeks of aerobic-yoga training on serum irisin, lipid profile and body composition of obese women.Method: Subjects were 16 obese female volunteers (age: 33.82±3.91 years, weight: 78.2±2.72 kg, BMI: 30.22±1.03 kg/m2) who were randomly divided into two groups of exercise (n = 8) and control (n = 8). The experimental group performed eight weeks of aerobic-yoga training, three sessions per week, 60 minutes per session, and with an intensity of 65-75% of the reserve heart rate. Blood samples were taken 24 hours before and 48 hours after exercise, and serum Irisin, lipid profile and body composition were measured. Independent t-test and ANCOVA were used to evaluate the mean difference before and after eight weeks of aerobic-yoga training. Significance level was considered P <0.05.Results: Serum irisin levels (P<0.0001) and HDL (P=0.003) significantly increased after eight weeks of aerobic-yoga training. Meanwhile, weight (P<0.001), WHR (P<0.001), BMI (P<0.0001), fat percentage (P<0.0001), fat mass (P<0.0001), LDL (P<0.001), VLDL (P<0.0001), TG (P=0.027) and cholesterol (P=0.002) significantly reduced after 8 weeks of aerobic-yoga training compared. LBM (P = 0.579) had no significant difference after eight weeks of aerobic-yoga training.Conclusion: Aerobic-yoga exercise reduces weight and improves irisin, body composition and blood lipid profile in obese women.

Aim: The aim of current study was to evaluate the effect of exercise day-time on maximal fat oxidation (MFO), exercise intensity (FATmax) and time (MFOtime) that elicite MFO and their relation to body composition in normal and overweight women. Metod: Forteen 20-30 years old students were randomly selected and participated in to two normal waight (20<BMI-2) and overweight (BMI>25 kg.m-2) group. The data were analyzed using statical teats of dependent and paire T- test to copmair changes between session results. Resuils: Mean value of MFO at morning was significantly higher in overweight group than that in normal group (p<0.05). Also, no significant differences were observed between groups at evening. There was no significant relationship between body fat percent and MFO at morning, nor at evening; however, there was a significant negative relationship between body fat percent and MFOtime in overweight group at evening (r=-0.92, p<0.05). Conclusion: Generally, it seems that maximal fat oxidation during exercise is higher in the people who have more body fat percentage. However, this is eveident at morning rather than evening and enhancing fat oxidation at evening may need longer time exercise with higher intensity.
