ABSTRACT Introduction Work activities have been occupying an increasing amount of time in the daily lives of the population, making individuals less physically active. A job market strategy is to invest in physical exercise programs in the actual workplace to improve the physical and cognitive aspects of these employees. Objective To verify the effects of a workplace physical exercise program on the simple and choice reaction times of public university employees. Methods Twenty-six physically inactive male and female subjects with a mean age of 29.62 ± 6.47 years underwent a program consisting of thirty-six sessions with physical exercises in the workplace, held three times a week over twelve weeks. Simple reaction time (SRT) and choice reaction time (CRT) were assessed before and after the intervention, using the Vienna Test System®, and the results were presented in: I) reaction time, II) movement time; and (III) response time. Descriptive and inferential statistical analyses were conducted using the statistical program SPSS® (version 21.0 for Windows), with a significance level of 5%. Results When observing the SRT and CRT variables before and after the experiment, we noticed an improvement in reaction time, movement time and response time in the experimental group but not in the control group. Conclusion The workplace physical exercise program was able to reduce the SRT and CRT of the experimental group. Level of evidence I; randomized clinical trial.

An intensive physical exercise program could lead to a decrease in immune system function. Effects of long-term supplementation of bovine colostrum on the response of immune function on physical exercise test in athletes were examined. Twenty-seven elite female basketball players (age 16–19) were randomly assigned to either an experimental group or a control group. Eventually, n = 11 athletes completed intervention in the experimental group (3.2 g bovine colostrum orally twice a day for 24 weeks), while n = 9 athletes in the control group were given a placebo. Before the supplementation, after 3 and 6 months, subjects performed the physical exercise stress test. Before, just after, and 3 h after physical exercise testing, blood was drawn and immune system indicators were examined. Plasma interleukin (IL)-1alpha, IL-2, IL-10, IL-13, tumor necrosis factor (TNF) alpha, creatine kinase (CK MM), immunoglobulin G (IgG), insulin-like growth factor 1 (IGF1), and WBC, lymphocyte (LYM), monocyte (MON), and granulocyte (GRA) were measured. A statistically significant change in IL-10 in response to the exercise program during the supplementation period in both groups was observed (p = 0.01). However, the results of the rest of the comparisons were statistically insignificant (p > 0.05). Contrary to our initial hypothesis, there were no significant effects of bovine supplementation on the dynamics of immune system function indicators.

The aim of this study is to examine the effects of 6-week Zumba exercises on flexibility, leg strength, back strength and muscular endurance parameters in women aged 25-45. The research group consists of a total of (n=20) women, (n=10) in the experimental group and (n=10) in the control group, between the ages of 25-45 living in Istanbul. The participants in the experimental group were given 60 minutes of Zumba exercises 3 days a week for 6 weeks, and sit-reach, 1-minute sit-up and strength test measurements were made to the participants before and after the exercise program. Participants in the control group were not included in any exercise program. As a result of the analysis, it was determined that there was a statistically significant difference between the participants' flexibility, leg strength, back strength and muscular endurance values between the pre-test and post-test within the group (p< 0.05). In addition, there was no significant difference between the pre-test and post-test values between the groups (p< 0.05). In conclusion; It was determined that zumba exercises applied to the experimental group did not have a significant effect on flexibility, muscular endurance and back strength. In the leg strength parameter, the effect of zumba exercises applied to the experimental group on leg strength was found to be significant at a rate of 34%. In the light of these data, it was concluded that zumba exercises performed in sedentary women have a positive effect on lower extremity strength.

Form rotation, figure directionality, and figure-ground discrimination were evaluated before and after 10 days of vestibular or aerobic exercises for 30 boys (7 to 12 yr.) who showed problems in learning, reading, and inattention. Eight subjects had normal vestibulo-ocular reflex (VOR) responses as determined by caloric and rotational testing. They were assigned to a vestibular program (Control Group I). The 22 subjects with abnormal VOR test responses were randomly assigned to either aerobic exercises (Experimental Group II) or a vestibular program (Experimental Group III). Spatial perceptual test scores varied widely, with the majority performing below age-expected norms but no significant differences on vestibular status appeared. Postexercise, only subjects completing the vestibular program made significant gains: Experimental Group III (abnormal VOR) made significant gains in accuracy and normal test responses compared to the other groups, and Control Group I made significantly greater gains in speed of spatial perceptual processing. For boys with problems in learning, reading, inattention, and vestibular function, a vestibular exercise program complementing a traditional or special educational program may enhance the spatial perceptual skills needed for reading.

Background: Physical exercise influences homocysteine (Hcy) concentrations, cognitive function and the metabolic profile. The purpose of this study was to investigate the influence of regular physical exercise on Hcy levels, the metabolic profile and cognitive function in healthy elderly males before and after an endurance exercise program. Methods: Forty-five healthy and sedentary volunteers were randomized into 2 groups: (1) a control group asked not to change their normal everyday activities and not to start any regular physical exercise program and (2) an experimental group trained at a heart rate intensity corresponding to ventilatory threshold 1 (VT-1) for 60 min/day 3 times weekly on alternate days for 6 months using a cycle ergometer. All volunteers underwent cognitive evaluations, blood sample analyses and ergospirometric assessments. Results: A significant improvement in cognitive function was observed in the experimental group compared with the control group (p < 0.05). No significant changes in Hcy levels were observed in the experimental group (p > 0.05), but there was a significant increase in peak oxygen consumption and workload at VT-1 as well as a significant improvement in cholesterol, triglycerides, HDL, glucose, alkaline phosphatase, urea, T3, T4 and prostate-specific antigen compared with the control group (p < 0.05). Conclusion: The data suggest that a physical exercise program does not reduce Hcy levels in healthy elderly males, although it improves the cardiovascular and metabolic profile as well as cognitive function.

Background: Sleep is an important phenomenon to restore the body, both physically and emotionally, providing a state of balance in the person. It has been proven that adequate sleep at night is one of the main needs of older people in order to maintain an active and healthy life; among other factors, regular physical exercise can improve the quality of sleep. The aim of this research is to evaluate the effects of a physical exercise program supplemented with vibration training on sleep quality and the use of sleep drugs in women over 65 years of age. Methods: Fifty-two independent, physically active adult women were randomised into two groups: a physical exercise program (n = 26, control group) and the same physical exercise program supplemented with vibration training (n = 26, experimental group). The control group performed two weekly sessions of exercise, and the experimental group added another two sessions of vibration training to these two sessions for 12 weeks. Sleep quality was assessed using the Pittsburgh index. Statistical significance was established as p < 0.05. Results: After the intervention, there were significant changes to the quality of sleep (p = 0.001) and hours of sleep (p = 0.002) in the experimental group. The consumption of drugs decreased in this group, although not significantly; however, it did have a moderate effect size (p = 0.058; d = 0.36). The control group, on the other hand, reported significantly worsened sleep quality (p = 0.001) and increased drug use (p = 0.008). Conclusion: Three months of vibration training, as a complement to a conventional physical exercise program, improves sleep quality and reduces the consumption of sleeping pills in women over 65 years of age.

The purpose of this study was to investigate the static and dynamic balance and body activities after administering a trunk stability exercise program using a sling for children with spastic cerebral palsy of Gross Motor Function Classification System (GMFCS) levels III–IV. This study was conducted based on a quasi-experimental study design. Six of the study participants were assigned to the control group and six were assigned to the experimental group using simple random sampling. Both groups underwent a double-blind clinical trial study in which exercise therapy was performed for 40 min twice a week for 8 weeks. The experimental group underwent the sling exercise program and the control group underwent neuro-developmental treatment. The results showed that static and dynamic balance were significantly different before and after intervention in both the experimental and control groups (P<0.05), and there was also a statistically significant difference between the two groups (P<0.05). Gross motor function and activities of daily life showed significant improvement before and after intervention in the experimental group (P<0.05), but there was no statistically significant difference in the control group (P<0.05). There was a statistically significant difference between the two groups (P<0.05). Therefore, the sling exercise program can be used as an effective treatment for improving balance and physical activity in children with cerebral palsy of GMFCS levels III–IV who have difficulty walking. In addition, such exercise will have a positive impact on the independence of such children and help them to participate in social activities.

Objective: This research aimed to study the effects of a physical exercise program on physical mobility in cranial surgery patients.Materials and Methods: The researcher used a quasi-experimental method of surveying 58 patients who had cranial surgery at Siriraj Hospital. The research group was divided into two groups: an experimental group (28 patients) participating in a physical exercise program of patients after cranial surgery, and a control group (30 patients) receiving routine nursing care only. The evaluation of the patients’ physical mobility was performed three days after the surgery.Results: Most patients in the research group had an intracranial tumor (86.2%). One day after the surgery, the experimental group had minor pain at the wound site while the control group had moderate pain. Both groups felt discomfort (64.2%) or had muscle stiffness in the neck and shoulder areas (63.3%). Three days after the surgery, at the end of the program, the body movement function of both groups was reduced compared with the preoperative data. However, the experimental group showed better body movement function scores than the control one as the scores of the former were reduced less than those of the latter at p < 0.05.Conclusion: Nurses who provide health care services to patients after cranial surgery should apply the physical exercise program to promote the recovery of the patients’ physical mobility.

Abstract Study aim: The symmetrisation of movements can be a way to develop individual coordinative skills, and to prevent the occur-rence of injuries. For this reason, in this study an attempt was made to evaluate and compare simple reaction time and movement time for épée fencers of different sports classes, and to determine the impact that three years of symmetrisation training and unilateral training have on the speed of reaction components and on dynamical asymmetry. Material and methods: The study was conducted on 60 women épée fencers of different sports classes, and it was repeated in two groups after three years of unilateral and symmetrisation training. Simple reaction time and movement time for the dominant and the non-dominant hand were analysed using Vienna Test System. Results: Women épée fencers of high sports class were characterised by a significantly faster reaction time than their less experienced colleagues. In tests conducted after three years of symmetrisation training, athletes from the experimental group achieved also much better results in reaction time (RT) than those from the control group training with the unilateral method. Conclusions: Long-time unilateral training of master class women épée fencers led to dynamical asymmetry, which in the future could cause injuries and have a negative impact on the development of selected motor skills. Symmetrical training conducted in the experimental group had a positive impact on reaction time indicators as well as on movement time indicators, and it prevented the occurrence of dynamical asymmetry in the tested competitors. Thus, it can be inferred that symmetrical exercises will have a positive impact on training effectiveness and on versatility of athletes.

A systematic decrease in heart rate when anticipating an important stimulus or when preparing to react is called anticipatory bradycardia. Numerous studies have shown that the initiation of motor activity prompts the termination of anticipatory bradycardia in reaction time tasks. However, in experiments with procedures based on more complex reactions, the termination of anticipatory bradycardia is delayed until later cardiac cycles. This unexpected effect may be attributed to perceptual processes that are engaged in the feedback mechanism essential for effectiveness in prolonged and complex motor reactions. The experiment presented in this article was carried out to verify the hypothesis that the initiation of a motor reaction, when processed simultaneously with sustained attentive perception, does not evoke acceleration of heart rate. The experimental task was a simulated shooting at a moving target. The procedure in the experimental group induced participants to attentively observe events before and after the required reaction, whereas in the control group, attentive perception of task events after the reaction was not possible. The expected pattern of heart-rate changes appeared in the experimental group. During the initial block of trials, the initiation of the motor reaction did not evoke immediate termination of anticipatory bradycardia. During later trials in the experimental group and during all trials in the control group, heart-rate changes were completely typical - heart rate increased after the motor reaction began. The results show that attentive perception engaged immediately after the initiation of motor activity can affect the pattern of phasic heart-rate changes observed during typical reaction time tasks. Additionally, the difference between the patterns characteristic of the initial and later trials suggests possible competition between the neuronal influences that modulate heart rate.

The effects of electromyographic (EMG) biofeedback on reaction time (RT) and movement time (MT) were investigated utilizing 42 right-handed, male subjects from a university population. Subjects were randomly divided into three groups, a control group and two experimental groups. Both experimental groups were exposed to their EMG signals from their triceps brachii during the task, one experimental group received written information explaining the purpose of the EMG was to improve performance through biofeedback. Reaction times of the first block of 25 trials were significantly faster than those on the subsequent three blocks of trials for all groups. This provided evidence of learning. No other significant effects for reaction times were observed. Mean movement time for the EMG-only group was significantly slower than the means of either the Control group or EMG-Biofeedback group, with no difference between the latter two. The differences between experimental groups may have been related to alteration of strategy, anxiety, or motivation.
