Introduction: In this study, the effect of aerobic training supplemented with hydro-alcoholic extract of Vaccinium Arctostaphylos fruit on oxidative stress and the antioxidant defense system of the heart tissue of rats was investigated.Methods: 24 male Wistar rats were randomly divided into four groups: 1-healthy control, 2-supplementation, 3-training, and 4-supplementation and training. Rats in the supplement groups received 250 mg of fruit Vaccinium Arctostaphylos per kg of body weight in the form of oral gavage. Aerobic training protocol included running on a treadmill at a speed of 5-24 m/min for 10-60 minutes for eight weeks, five days a week, with the principle of overload. The levels of SOD, TAC, GPX, and MDA were measured in heart tissue. Results: The results showed that the level of SOD increased significantly in the training+supplement group compared to the control group (p=0.044). The level of TAC in the supplement group was higher than the training and training+supplement groups (p

Aim: The aim of the present study was to investigate the effect of proprioceptive exercises and massage on anaerobic performance and some physical fitness factors of women athletes. Methods: 28 women athletes with an average age of 24.8 ± 2.25 and weight of 60.02 ± 6.26 in four groups; the experimental group (1- massage, 2- proprioception exercises, 3- massage+ proprioception exercises) and the control group were randomly divided. In the pre-test session, all the subjects, with a four-minute warm-up in the form of jogging with an intensity of 30-40% HR, performed tests of anaerobic performance and some physical fitness factors and after a 72-hour washout period, the subjects started their activity for 12 minutes, each in their specialized group and according to the established protocol, and immediately the tests of the pre-test stage were repeated. A dependent t-test and one-way analysis of variance were used to analyze the data. Results: The results showed that the massage + proprioception group had a significant effect on the anaerobic peak power variable by 36.3%. All three groups of massage, proprioception, and massage +proprioception had a significant effect on the variables of average anaerobic power and fatigue index. In the variables of peak anaerobic power (p=0.001), average anaerobic power (p=0.011), fatigue index (p=0.016), and dynamic balance (p=0.015), there is a significant difference between the groups (p>0.05). Conclusion: In anaerobic activities, the use of proprioception exercises along with massage as part of warming up sports activities will most likely improve the performance of athletes.

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.
