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.

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.
