Abstract
Performing a mental exertion during an exercise increase fatigue indices and the amount of fatigue seems to depend on the type of mental exertion. 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 peak power output 236 ± 36 W invited for 5 different sessions. In the first session, anthropometric characteristics and of cycling peak power output (PPO) 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 mental exertion. Rate of perceived exertion (RPE) 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 RPE 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 the present study showed that performing Stroop mental exertion during the cycling exercise than cycling exercise alone increase more 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. The present 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 brain of female mice after EAE induction. In this research, 21 mice (8 weeks old, 18 to 20 grams) were divided into 3 groups: healthy control, EAE control, and EAE swimming aerobic exercise. The animals in the training group performed moderate-intensity swimming exercises for 4 weeks, 5 sessions per week, 30 minutes per session. The western blot method was used to analyze the research variables. One-way analysis of variance and Tukey's post hoc test were used for statistical analysis. The results showed that there was no significant difference in the amount of IL-6 between the EAE group and swimming training, but the amount of IL10 in the swimming training group showed a significant increase compared to the EAE group. However, the ratio of IL 10/IL 6 values between the swimming training group with EAE was also not significant. It seems that moderate-intensity swimming aerobic exercises, without change in the pro-inflammatory factor, along with driving towards anti-inflammatory factors, with an increase in IL10, can lead to an improvement in the balance of the inflammatory index and a reduction in fatigue between the EAE group and swimming exercise.

Abstract
Mental fatigue is usually caused by long-term cognitive activities; in a way that reduces cognitive performance and leads to changes in functional activities. Therefore, the purpose of this study was to investigate the effect of a session of Swedish relaxation massage and meditation in controlling mental fatigue on reactive balance and Lower extremity function of amateur athletes. In this study, 16 female physical education athletes were purposefully selected as a sample based on the study entry criteria, and were subjected to mental fatigue protocol (45 minutes of cognitive activity (Stroop test)), Swedish relaxation massage (30 minutes) and meditation (30 minutes) with a time interval of 48 hours. Reactive balance was evaluated with Y test with automatic lights and, Lower extremity function was evaluated with single hop for distance, triple hop for distance, meter-6 and hop crossover-triple distance tests. Repeated analysis of variance test was used to check intra-group changes.The findings showed that there is a significant difference between the average scores of reactive balance and lower limb performance of the subjects when comparing the post-test of mental fatigue with the post-test of massage and meditation (P<0.05). Also, there is a significant difference between the subjects' scores comparing massage and meditation for reactive balance and body function (P<0.05).In order to prevent sports injuries in athletes, Swedish relaxation massage and meditation can be used as an intervention to speed up the recovery of mental fatigue and improve reactive balance and body function.
