Abstract
The aim of this study is the effect of one period core stability exercise with and without kinesio taping on biomechanical effective factors in lower cross syndrome on female. 36 female between 30 to 40 were randomly divided in to 3 groups (control, with taping and without taping). each group consist 12 participant. To measure Pelvic slope, Hip and Knee ROM, Isometric strength of flexors and extensors, Abdominal muscle endurance, Flexibility of spine extensors, Endurance of core muscles, respectively was used Inclinometer, Goniometer, Dynamometer, Body flection test, Body straightening test and Planck test to the side. To evaluate research hypotheses, if there is a significant difference between them we was used analysis of covariance test and multiple comparison in averages with post hoc bonferroni test. The result of the survey indicate that difference between taping and control groups were significant in pelvic slope, hamstring and rectus femoris flexibility, knee and hip flexors muscle strength )p≥0/05(. Difference between without taping and control groups were significant in pelvic slope, rectus femoris and spine extensors flexibility (p≥0/05(. Difference between with and with¬out taping groups were significant in hamstring and iliopsoas flexibility, knee flexors, hip flexors, extensors, adductors strength, core muscles endurance )p≥0/05(. The results show that training with taping has an effective role on reducing lower cross syndrome. So it is suggested that taping can be used as an non-aggressive and low-cost method at the same time with exercise.

Abstract
The researchers conducted the present study with the aim of investigating the pain and muscle disorders of patients with covid-19 with people who have experienced it. The research was applied and comparative. Samples were calculated using G-power of 303 people, and sports teachers were excluded from the research. The Nordic questionnaire was provided to Ardabil education and training employees after the investigation, the number of people with one year of identification and the number of 113 people with the age range of 30 to 45 years reported no reduction. Then, musculoskeletal disorders of 9 body areas in both groups were evaluated using descriptive statistics and chi-square test at a significance level of 0.01. The muscle pain of the affected group was significantly (P<0.01) higher than that of the healthy group, and also based on the chi-square test, the amount of back and neck pain was 52% and 45%, respectively, in affected people compared to other organs. It was more meaningful. (P<0.01) noticed that there was no significant difference between the pain and discomfort of different organs in the non-observed group. Corona patients may experience pain, and the cause of it in the Nordic questionnaire, in addition to physical abnormalities and excessive muscle disease, can be from Corona disease; Therefore, the Nordic questionnaire should be used.

Abstract
Upper-crossed syndrome is one of the most common disorders of the upper body, which is associated with 45-65% of shoulder pain. This study has been conducted to investigate the effect of corrective exercises focused on chain reactions, on scapular position, proprioception and shoulder functional stability of female students with UCS. 30 female students between 14 and 18 years of age in Urmia city who had the mentioned disorder were selected using the purposive sampling method and were randomly divided into two experimental groups (15 people) and control (15 people). A tape measure was used to evaluate the distance between the median of the sternum to the coracoid ridge and the posterior-lateral distance of the acromion to the thoracic vertebra (scapular position), the Layton flexometer to measure proprioception, the Y Balance Test to evaluate the function of the upper limb, and the goniometer, tape measure and flexible ruler, respectively were used to measure head and shoulder forward angle and kyphosis. Independent and dependent t-tests were used to compare inter-group and intra-group means, respectively. The present study showed that the effect of corrective exercises on scapular position, proprioception and shoulder functional stability of female students with UCS was significant.

Abstract
The aim of this research was effect of eight weeks of neuromuscular training (NMT) with and without cognitive-dual tasks (DTs) on proprioception and balance of athletes with ACL deficiency (ACL-D). 39 soccer players with ACL-D were selected purposefully and randomly divided into three groups of 13 (control group, neuromuscular training group and neuromuscular training with dual tasks group). Two training groups performed the exercises for eight weeks and three sessions per week. cognitive-motor dual tasks were performed in one of the groups along with neuromuscular exercises in the form of counting down numbers, memorizing numbers, calculating unexpected equations, specialized football skill movements. The results of the current study indicated that there was no significant difference in knee joint proprioception in the open and closed kinetic chain after applying the intervention between the three groups, but there was a significant difference in lower extremity performance of the athletes based on the Y balance test in the anterior and posterior-lateral direction between the three groups (p<0.05). It seems that providing neuromuscular exercises along with cognitive-dual tasks can probably be considered as a useful approach to improve lower extremity performance based on the Y balance test in athletes with anterior cruciate ligament deficiency.

Abstract
Nowadays, the use of traditional herbal remedies for the prevention and treatment of diseases along with exercise has become very popular. The aim of this study was to investigate acute effect of hydro alcoholic extract of melissa officinalis on metabolic rate, substrate oxidation and salivary cortisol during and after high-intensity interval exercise (HIIE) in inactive women. Ten inactive women were selected based on criteria (BMI 22.28±0.60 kg/m2). Individuals participated in two separate sessions. In the first session, extract of melissa officinalis (500 mg) were intake one hour before HIIE. In the second session, the placebo (500 mg of starch) was intake. The HIIE program consisted of 11 alternates (1-minute with 90% vVO2max followed by 2-minute rest intervals with 60% vVO2max). Pre, during and after HIIE, respiratory gases was measured using the respiratory gas analyzer and was used to calculate metabolic rate (Energy Expenditure, VO2) and substrate oxidation (Fat oxidation, Respiratory Exchange Ratio (RER)). Heart rate monitored by polar sensor. Salivary cortisol after collection was measured by chemiluminescence method. Based on results, there was no significant difference in VO2 (P =0.51), Fat Oxidation (P= 0.9), RER (P= 0.76), Heart rate (P= 0.42) and energy expenditure (P=0.6) between melissa officinalis and placebo intake. Also, there was no significant difference in salivary cortisol (P= 0.15). Generally, hydro alcoholic extract of melissa officinalis supplement intake along HIIE has no effect on metabolic rate, substrate oxidation and cortisol level in inactive women.

Abstract
Performing a mental exertion before and during an exercise increase fatigue indices. One of the important factors in inducing fatigue indices is the type of mental effort engaged. So, the purpose of the present study is comparing the effects of performing types of mental exertion during cycling exercise on fatigue indicators. Methods: 10 cyclist men (with average age 34.5 ± 4.5 kg, height 177 ± 4.5cm, peak power output 236 ± 36 W) invited for 5 different sessions. In the first session, anthropometric characteristics and of cycling peak power output have determined. In the next four sessions, cycling for 45-min at 65% PPO on the cycle ergometer with (Stroop, AX-CPT and PVT) or without (watching a movie) mental exertion. Rate of perceived exertion and heart rate were recorded while cycling every 10 min and cortisol concentration was measured before and 30 min after exercise finished. Two-way repeated-measures ANOVAs were used to analyzing data. Results: Performing 45 minutes of Stroop mental exertion during cycling exercise increased effort perception, mental demand in the NASA questionnaire, and cortisol concentration compared to cycling exercise alone (P˂0/05) but there is no differences between AX-CPT and PVT to cycling exercise alone . Conclusion: The results of present study showed that performing different mental effort simultaneously with the cycling exercise depending on the amount of challenge and their duration may affect some of the fatigue indices.

Abstract
Fatigue is one of the most common symptoms among individuals with multiple sclerosis (MS). The imbalance of inflammatory cytokines in the brain causes mental fatigue. It is believed that aerobic exercise may moderate the level of inflammation of cytokines and thus reduce mental fatigue. This study was conducted to investigate the effect of swimming aerobic training on pro-inflammatory factors (interleukin 6) and anti-inflammatory factors (interleukin 10) to evaluate mental fatigue in the brains of female mice after EAE induction. In this research, 21 mice (8 weeks old, 18 to 20 grams) were divided into three groups: healthy control, EAE control, and EAE swimming aerobic exercise. The animals in the training group performed moderate-intensity swimming exercises for 4 weeks, with 5 sessions per week, each session lasting 30 minutes. The western blot method was used to analyze the research variables. The results showed no significant difference in the amount of IL-6 between the EAE group and the swimming training group, but the amount of IL-10 in the swimming training group showed a significant increase compared to the EAE group. The ratio of IL-10/IL-6 values between the swimming training group and the EAE group was also not significant. It seems that moderate-intensity swimming aerobic exercises, without changing the pro-inflammatory factor, along with increasing the anti-inflammatory factor IL-10, can lead to an improvement in the balance of the inflammatory index and a reduction in fatigue in the EAE group and the swimming exercise group.
