The Subject

Background:Exercise, especially aerobic exercise thought to have a positive impact on cognitive and brain function which mainly involved in acquisition, processing, storage and executive functions. Executive control processes are important in sport and occupational settings where a person is being asked to make decisions while performing physical work. We have done this study, to determine the effects of acute moderate intensity exercise on cognitive domains and to apply this knowledge in various fields where cognition and executive functions are important. Study and control population each consists of 60 apparently healthy subjects in the age group of 18-30 years.Methods:The material used for study Cosco Upright Exercise Bike and Reaction Time apparatus. Visual Choice Reaction Time, the examiner presented visual stimuli at random to the subject. The subject saw the light displayed on his side and pressed the appropriate corresponding button as quickly as possible and the reading was noted. The same procedure was repeated for auditory choice reaction time for auditory stimuli. After that each subject from study population underwent acute moderate intensity aerobic exercise on for 10 minutes. Starting within 5 minutes after the exercise, subjects were assessed for the same cognitive test as above, for the second time. Control population rested for 10 minutes and then was assessed again for the same cognitive test.Results:There was no significant difference between the pre- values of study population and pre- values of control population. There was no significant difference between the pre- values of control population and post values of control population. Thus, there was no improvement in cognitive functions on account of repetition of tests. There was a significant difference between the post values of study population and post values of control population. There was a significant difference between the pre- values of study population and post values of study population.Conclusions:There was a decrease in reaction time following exercise in the study population, suggests that there was an improvement in the cognitive functions post exercise.

Related Stress

Two tasks (simple and choice reaction time) were examined while varying three types of stressors (shock, threat of shock, and noise) and the stressor task relationship (i.e., task-related stress, task-unrelated stress, and no-stress). Four specific hypotheses were tested and 3 were supported in the simple reaction-time task. There were no significant differences among stressors for either task, although greater differences were reported in the simple than in the choice reaction-time task. A significant difference between the “task-relatedness” of stress levels in the simple task was interpreted as possibly due to a “coping” or “protective adaptive mechanism” in which increases in performance serve to reduce stress. Practical applications were examined.

The Relationship

Three experiments were performed which examined the applicability of the Hick-Hyman law to the design of an auditory interface for a vehicle collision avoidance warning system. All trials used a single broadband noise signal emanating from one of a subset of six loudspeakers equally spaced around the subject in the azimuthal plane. Both the size of the sub-set and the balance of relative probabilities from speaker to speaker were altered to evaluate the relationship between information content and the dependent variable, choice reaction time. Choice reaction time was found to be related to the information content of the sound stimulus in all cases. It was also found to be related to the presence of pairs of speakers which were symmetrically opposed to one another in front of and behind the subject.

Maximum Grip

The present study examined whether varying magnitude of force required to perform an isometric response influences fractionated reaction time in simple and choice conditions and whether reaction time and premotor time to initiate the response are shorter when force is selected freely by the subject than when it is selected by the experimenter. 20 subjects were required to react and produce a designated peak force as quickly and accurately as possible by squeezing a handle after a reaction signal. Four different magnitudes of force were 30, 50, and 70% of the maximum grip strength of the subjects and subject-selected magnitude of force. Reaction time and premotor time did not change across the range of forces examined in both simple and choice reaction-time conditions regardless of whether a desired force was selected by the experimenter or by the subject These findings suggest that programming an isometric response may require a constant amount of time.

Abstract Backgrounds and ObjectivesThe use of anti-inflammatory supplements is important in improving the executive function of obese people. The aim of this research was to investigate the effect of 6 weeks of aerobic exercise with moderate intensity and consumption of nanocurcumin on IL1β, nitric oxide, and depression in women aged 60-65 with metabolic syndrome. Materials and Methods44 women with metabolic syndrome (MetS) were randomly selected and divided into four groups of 10, including MetS exercise+ Curcumin (MECU), MetS exercise (ME), MetS NanoCurcumin (MCU), MetS control (MC Training groups performed an exercise protocol of aerobic exercise for 6 weeks (three sessions per week). Blood samples were obtained before and after the training period for antioxidant indicators and lipid degradation measurement. Also, the Beck anxiety questionnaire was used for evaluating levels of anxiety. T-test and one-way analysis of variance were used for the evaluation of within-group and between-group differences, respectively.ResultsThere was a significant difference in IL1β, nitric oxide (NO), and depression before and after exercise in all three experimental groups (p≤0.05). Also, the results showed a significant difference in the level of NO and depression in the research groups. The highest decrease in these variables was observed in the aerobic training group and training with nanocurcumin consumption group (p≤0.05).ConclusionThese findings indicated that six-week nanocurcumin supplementation with aerobic training is a suitable method for reducing IL1β and NO and depression, preventing metabolic, cardiovascular, and inflammatory diseases in women with metabolic syndrome.Name of the registry: IR.SEMUMS.REC.1396.107Trial registration number: IRCT2017082335857N1

A growing body of work has investigated the effects of acute, or single bouts of, aerobic exercise on cognitive function. However, review of this research has largely focused on changes following exercise, with less focus on cognitive changes during exercise. The purpose of this review is to discuss the critical characteristics of this literature to date, including: (1) what has been done, (2) what has been found, and (3) what is next. Furthermore, previous meta-analytic reviews have demonstrated there is a small positive effect on cognition when measured during exercise, with executive functions showing the largest effects. However, these reviews group executive functions together. Here we explore how inhibition, working memory and cognitive flexibility are individually impacted by factors such as exercise intensity or duration. Searches of electronic databases and reference lists from relevant studies resulted in 73 studies meeting inclusion criteria. Studies were grouped by executive and non-executive cognitive domains, intensity and duration of exercise bouts. Within the executive domain, we found that effects on working memory and cognitive flexibility remain mixed, effects on inhibition are clearer. Moderate intensity exercise improves response time, vigorous intensity impairs accuracy. Moderate to vigorous intensity improves response time across non-executive domains of attention, motor speed and information processing, with no significant effects on accuracy. Memory processes are consistently improved during exercise. Effects of exercise duration on response time and accuracy are nuanced and vary by cognitive domain. Studies typically explore durations of 45 min or less, extended exercise durations remain largely unexplored. We highlight factors to consider when assessing exercise-cognition relationships, as well as current gaps and future directions for work in this field.

Objective cancer-related fatigue(CRF) is the most commonly reported and most distressing symptom in cancer patient.The purpose of this study was to review the effect of exercise intervention on cancer-related fatigue in breast cancer survivors. Methods From 1998 to 2018 in Chinese and English literature of Wanfang Database, Pubmed, SportDiscus and Springer databases, picked out the randomized controlled trials which up to standard. Keywords cancer, exercise, fatigue, etc. were used for systematic search and tracking. 12 experiments were reviewed to analyze the effect differences between exercise intervention and exercise-related fatigue. Results Most interventions use aerobic exercise as the primary form of exercise. Generally, exercise interventions are effective for cancer-related fatigue, but some findings are not. Many studies have shown that moderate intensity aerobic exercise has a significant effect on cancer-related fatigue, with 50-70% heart rate reserve and 3-5 times of exercise per week for at least 30 minutes each time. Exercise methods mainly include walking, yoga, cycling and tai chi. Firstly, Supervised aerobic exercise was statistically more effective than conventional care in improving CRF among breast cancer survivors. It has been shown that group-based, supervised exercise produces positive psychosocial‘side-effects’ due to social interactions, improved self-efficacy, and attention from a trainer. Secondly, Cancer fatigue is divided into acute and chronic fatigue, 18 weeks of exercise intervention can reduce the short-term fatigue, at 36 weeks, baseline levels of fatigue index responses and contrast on the issue of the multivariate statistics. Thirdly, usual-care group were reported that they had been actively engaged in regular exercise before study enrollment. During the exercise intervention, most studies on the control ways are according to the daily life or to take care of, but studies have reported, before intervention, to a high level of 40% in the control group often exercise, exercise also as usual during the intervention, which causes the control to the baseline level is higher, but the intervention group and control group will be difference, no significant difference, lead to the result is invalid. Conclusions First, the exercise intervention of cancer-related fatigue needs to be supervised; second, the exercise intervention is effective for short-term cancer-related fatigue; third, the daily exercise level of the control group will affect the intervention effect.

Aerobic exercise (AE) and transcranial direct current stimulation (tDCS) are priming techniques that have been studied for their potential neuromodulatory effects on corticomotor excitability (CME), however the synergistic effects of AE and tDCS are not explored in stroke. Here we investigated the synergistic effects of AE and tDCS on CME, intracortical and transcallosal inhibition, and motor control for the lower limb in stroke. 26 stroke survivors participated in three sessions - tDCS, AE and AE + tDCS. AE included moderate intensity exercise and tDCS included 1 mA of anodal tDCS to the lower limb motor cortex with or without AE. Outcomes included measures of CME, short interval intracortical inhibition (SICI), ipsilateral silent period (iSP) (an index of transcallosal inhibition) for the tibialis anterior and ankle reaction time. Ipsilesional CME significantly decreased for AE compared to AE + tDCS and tDCS. No differences were noted in SICI, iSP measures or reaction time between all three sessions. Our findings suggest that a combination of exercise and tDCS, and tDCS demonstrate greater excitability of the ipsilesional hemisphere compared to exercise only, however these effects were specific to the descending corticomotor pathways. No additive priming effects of exercise and tDCS over tDCS was observed. Novelty: • An exercise and tDCS paradigm upregulated the descending motor pathways from the ipsilesional lower limb M1 compared to exercise. • Exercise or tDCS administered alone or in combination did not affect intracortical or transcallosal inhibition or reaction time.

Background: Glial fibrillary acidic protein (GFAP) and heat shock protein -27 (HSP27) plasma can be used as the parameters of exercise-induced astrocyte reactivity. The American College of Sports Medicine (ACSM) recommends an exercise of 30 minutes or 10 minutes duration (each performing bout accumulated toward 30 minutes). The aim of this study was to compare GFAP and HSP27 plasma concentrations in young adults undergoing acute moderate-intensity aerobic exercise of different durations (10 minutes vs 30 minutes).Methods: An experimental study with pre-post design was conducted on 22 participants assigned to either 10 minutes or 30 minutes duration of single bout exercise. Blood sampling was performed before and after the exercise. GFAP and HSP27 plasma levels were measured with ELISA methods. Plasma GFAP and HSP27 levels before and after exercise were analyzed using paired t -test, while GFAP and HSP27 levels after exercise between the two groups were processed using unpaired t-test.Results: Plasma GFAP concentration decreased significantly (0,45 ng/mL) after 30 minutes of aerobic exercise (p<0.05). Plasma HSP27 concentration decreased significantly (1,71 ng/mL) after 10 minutes of aerobic exercise (p<0.05). No significant difference in plasma GFAP and HSP27 concentrations between 10 minutes (GFAP=0.49 ng/mL; HSP27=2.09 ng/mL) and 30 minutes duration of exercise (GFAP=0.45 ng/mL; HSP27=1,71 ng/mL).Conclusion: Acute moderate-intensity aerobic exercise with 10- and 30-minutes duration reduces the reactivity of astrocytes indication the increase of the synapse plasticity. The decrease in GFAP concentration occurred after 30 minutes of exercise and the decrease in HSP27 occurred after 10 minutes of exercise. These results showed that the body responds differently to different treatment duration in order to obtain the same effect on the body.

Abstract: Aerobic exercise with mild to moderate intensity will improve health and fitness. Aerobic exercise stimulates an increase in the concentration of IL-8 and will attract neutrophils out of circulation and infiltrate into the damaged tissue for physical activity. To determine the effect of mild and moderate aerobic exercise on levels of interleukin 8 and the number of neutrophils in adolescents, semi-experimental research laboratory with the entire population of male students of SMAN I Banjarbaru. Determination of the sample with inclusion and exclusion criteria obtained 31 samples (9 mild aerobic exercise, moderate aerobic exercise 12 and 10 as a control). The implementation of data collection (blood plasma) immediately after the sample is finished doing aerobic exercise. Blood plasma samples were analyzed by flowcytometri to see the number of neutrophils and elisa to see the levels of Interleukin 8 (IL-8). The results showed that mean plasma levels of IL-8 in mild aerobic group (605.69 ± 123.28) and moderate (718.75 ± 132.55) is lower than the control group (720.80 ± 213.11). Kruskal Wallis statistic test in the three groups no significant difference with p = 0.320. The average number of neutrophils mild aerobic exercise group (52.42 ± 8.29) and moderate (63.60 ± 8.73) was higher than the control group (50.11 ± 5.55), which means that there is an increase in the number of neutrophils after aerobic exercise , with one-way ANOVA statistical test showed different significant with p = 0.001. LSD test found significant differences between mild and moderate aerobic group with p = 0.003, 95% CI. There is no difference between the control group mild aerobic with p = 0.519. There are differences between the groups of moderate aerobic and control with p = 0.000. It can be concluded that mild and moderate aerobic exercise did not affect the increased plasma levels of interleukin-8 in adolescents. Mild aerobic exercise had no effect on the increase in the number of neutrophils in adolescents. Moderate aerobic exercise influence on the increase in the number of neutrophils in adolescents.Keywords :  Aerobic exercise, Interleukin 8, Neutrophyl Abstrak: Latihan aerobik dengan intensitas ringan sampai sedang akan meningkatkan kesehatan dan kebugaran tubuh.
