Introduction: Sports initiation is usually started during childhood and adolescence, and the beneficial effects of this practice for physical and motor capacities are already known. Recent research has shown the potential of sports to stimulate and modify cognitive development. Objective: To verify the relationship of sports practice during childhood on cardiorespiratory, motor, attention, cognitive flexibility and cognitive processing speed. Methods: 130 students aged 7 to 10 years participated in the study, of which 68 were athletes and 62 non-athletes, divided into sports group and control group. The researchers carried out three visits for the application of the research instruments, which were carried out in a randomized manner within the school premises, divided into three blocks: 1) attention test for cancellation and test of tracks A and B (applied collectively); 2) jumping tests; 3) anamnesis, body composition and the Körperkoordination für Kinder (KTK) test. Results: Children practicing sports obtained lower values ??in the weight (28 ± 10.08 kg vs 33.9 ± 15.3 kg), waist circumference (57.8 ± 7.7 cm vs 61.7 ± 9.6 cm) and circumference of the hip (69.1 ± 9.5 cm vs 72.8 ± 10.5 cm). In addition, we observed higher values ??in single-hops scores (96.9 ± 17.3 vs 85.6 ± 14.3) and lateral jumps scores (99.1 ± 18.8 vs 91.2 ± 18.0) compared to children who do not play sports. (p < 0.05). The high performance in single-heel jumps, side jumps, motor quotient, B-trails and B-A trails presented as predictors of sports practice (CI > 0.50). Conclusion: The results indicated a positive relationship between children practicing sports in childhood and interesting benefits in the ability of cognitive flexibility, without expressing differences in motor coordination compared to non-practicing children.

The Impact

Background: Parkinson’s disease (PD) is the second most common neurodegenerative disorder. This disease is characterized by motor symptoms, such as bradykinesia, tremor, and rigidity. Although balance impairment is characteristic of advanced stages, it can be present with less intensity since the beginning of the disease. Approximately 60% of PD patients fall once a year and 40% recurrently. On the other hand, cognitive symptoms affect up to 20% of patients with PD in early stages and can even precede the onset of motor symptoms. There are cognitive requirements for balance and can be challenged when attention is diverted or reduced, linking a worse balance and a higher probability of falls with a slower cognitive processing speed and attentional problems. Cognitive rehabilitation of attention and processing speed can lead to an improvement in postural stability in patients with Parkinson’s. Methods: We present a parallel and controlled randomized clinical trial (RCT) to assess the impact on balance of a protocol based on cognitive rehabilitation focused on sustained attention through the NeuronUP platform (Neuronup SI, La Rioja, Spain) in patients with PD. For 4 weeks, patients in the experimental group will receive cognitive therapy three days a week while the control group will not receive any therapy. The protocol has been registered at trials.gov NCT04730466. Conclusions: Cognitive therapy efficacy on balance improvement may open the possibility of new rehabilitation strategies for prevention of falls in PD, reducing morbidity, and saving costs to the health care system.

BackgroundDepression is associated with alterations of emotional and cognitive processing, and executive control in particular. Previous research has shown that depressed patients are impaired in their ability to shift attention from one emotional category to another, but whether this shifting deficit is more evident on emotional relative to non-emotional cognitive control tasks remains unclear.MethodThe performance of patients with major depressive disorder and matched healthy control participants was compared on neutral and emotional variants of a dynamic cognitive control task that requires participants to shift attention and response from one category to another.ResultsRelative to controls, depressed patients were impaired on both tasks, particularly in terms of performance accuracy. In the neutral go/no-go task, the ability of depressed patients to flexibly shift attention and response from one class of neutral stimuli to the other was unimpaired. This contrasted with findings for the emotional go/no-go task, where responding was slower specifically on blocks of trials that required participants to shift attention and response from one emotional category to the other.ConclusionsThe present data indicate that any depression-related difficulties with cognitive flexibility and control may be particularly evident on matched tasks that require processing of relevant emotional, rather than simply neutral, stimuli. The implications of these findings for our developing understanding of cognitive and emotional control processes in depression are discussed.

Introduction: Immunomodulator glutamine and probiotic Lactobacillus at certain doses have beneficial effects by modulation of the immune system and may assist in the integrity of therespiratory system. However, studies about the effects of glutamine or Lactobacillus pool on the prevention and control of asthma in children are still scarce. The aim of study was to evaluate the effect of the use of glutamine and Lactobacillus pool on the attenuation of clinical asthma symptoms in children. Methods: Longitudinal study, 45 children with medical diagnosis of asthma distributed in three groups: control group (C), glutamine group (G), Lactobacillus group (L). Group G was supplemented with L-glutamine powder (0.3 g/kg/day). Group L used a pool of Lactoba- cillus (Lactobacillus casei, paracasei, rhamnosus, acidophilus and Bifidobacterium lactis) (2 g/day). Group C received no glutamine or Lactobacillus pool. Clinical characteristics and symptoms of respiratory diseases were assessed by study-specific anamnesis and ISSAC Questionnaire (to obtain diagnostic scores and asthma symptoms) for 4 months. To test for differences between groups, the ANOVA test with Tukey post-hoc test was used. It was considered significant p <0.05. Results: Initial ISSAC score was (C=8.67±1.77, L=7.80±1.52 and G=8.00 ± 1.46, p=0.31). At the first follow-up, the ISSAC score indicated that group G had improvement in the clinical characteristics of asthma (C=6.47±2.29, L = 5.07±2.28, G = 4.00±1.73, p <0.05), as also occurred in the following months until the last follow-up (C=5.93±2.28, L=5.13±2.13, G=4.00±1.96, p<0.05). After supplementation, group G presented lower mean duration of asthma attack (p=0.01), lower number of asthma attack (p<0.05), lower prevalence of typical asthma symptoms, as cough and wheezing (p<0.05). Conclusion: Glutamine supplementation attenuated the typical asthma symptoms, while the use of Lactobacillus pool did not attenuate the symptoms. Glutamine may be a new strategy for prevention and control of asthma in children.

AbstractBackground:The aim of this study was to determine the serum levels of kisspeptin and ghrelin (GAH), as well as the relationship of these two peptides with each other in premature thelarche (PT) and premature adrenarche (PA) cases and to investigate the possibility of using these peptides as markers in the differentiation of puberty disorders.Methods:A PT group aged 1–8 years (n = 40), a PA group aged 1–9 years (n = 23, female/male = 20/3) and control groups consistent with each of the previous groups in terms of age and gender were created for the study. Kisspeptin and ghrelin levels were measured with ELISA methods from blood samples drawn while fasting in the morning.Results:When the PT group was compared with the controls, the plasma kisspeptin levels of the cases were significantly higher than the control group (165.47 ± 15.45 pmol/L, 96.82 ± 12.33 pmol/L, p = 0.005, respectively). Kisspeptin levels in the PA group did not show a difference with the control group (121.36 ± 17.99 pmol/L, 95.52 ± 11.54 pmol/L, p = 0.249, respectively). No significant difference could be found when GAH levels in the PT and PA groups were compared with controls. No significant correlation was found between kisspeptin and GAH levels in the PT and PA groups.Conclusions:Our results indicate that kisspeptin plays an important role in the PT, but GAH is not associated with puberty disorders.

In hypercatabolic patients, the beneficial effects of glutamine on gut mucosa could be partly due to a stimulation of protein synthesis. The fractional synthesis rate (FSR) of gut mucosal protein was measured in four groups of healthy volunteers treated with glucocorticoids for 2 days. Two groups were studied in the postabsorptive state while receiving glutamine or a nitrogen equivalent (control) and two groups in the fed state with or without glutamine, using a 5-h intravenous infusion of [13C]leucine, [2H5]phenylalanine, and cortisone. After nutrient and tracer infusion, duodenal biopsies were taken. In the postabsorptive state, FSR of gut mucosal protein were 87 and 76%/day in the control group and 130% ( P = 0.058 vs. control) and 104% ( P = 0.17 vs. control)/day in the glutamine group, with leucine and phenylalanine as tracers, respectively. During feeding, FSR did not increase and no significant difference was observed between glutamine and control groups. Overall, FSR of the four groups were two- to threefold higher than those obtained previously in healthy humans, suggesting that glucocorticoids may increase gut mucosal protein synthesis. However, in this situation, a moderate enteral glutamine supply failed to demonstrate a significant effect on gut mucosal protein synthesis in the postabsorptive state and during feeding.

Coach workshops based on seven principles (inspiration, explanation, expectation, support, reward, appreciation, growth and winning) enhance the sport experience of adult athletes. Therefore, we have investigated the effects of such workshops with coaches of child athletes. Study participants were coaches of 57 9- to 12-year old girls (practicing gymnastics) and boys (practicing football). Three coaches of 28 children attended three workshops over 12 weeks, while a control group of 5 coaches of 29 children attended no workshops. Measures of well-being and psychomotor performance were taken on the children before and after the intervention; differences in mean changes between intervention and control groups were adjusted for baseline, standardized, and assessed with a conservative magnitude-based decision method. There were clear substantial effects of the workshop on motivation averaged across several dimensions (girls, large, most likely beneficial), on a decision test (boys, small-moderate, very likely beneficial), on state anxiety self-reflection (girls, moderate, likely harmful), and on reaction time (boys, small, possibly harmful). The beneficial effects of the workshop in this pilot study are encouraging, but the unclear and potentially harmful effects and the roles of presenter- and coach-specific effects need to be investigated further with a representative sample of coaches and more children before the workshop is recommended for implementation.

Abstract Background The coach attitude impacts the whole mind and body system of a child athlete from emotional and motivational aspects to motor skills like motor coordination. It translates into the ability to control and stabilize posture. The vestibular system plays an important role in this regulation. This system, next to the visual system and mechanoreceptors, is responsible for balance and control during posture transition. Moreover, the vestibular system is influenced by emotional factors. Therefore the authors of this study focused on the changes in the balance stability of children practicing sport after the implementation of the psychological workshops for coaches. Methods Fifty-nine children at the age of 9–12 practicing soccer, art gymnastic and sport gymnastic were divided into two groups. The experimental group consisted of 31 participants and 28 in the control group. Experimental group children were under the influence of the 3 coaches who attended three workshops over 12 weeks period. Control group children were coached by 5 coaches who attended no workshops. Postural stability tests were performed on children before and after the workshops. Results The statistically significant changes were observed in selected parameters of children’s balance stability after the experiment. The significant difference between the experimental and control group in Overall Stability Index (OSI) (p < 0.0002), Anterior–Posterior Stability Index (AP) (p < 0.01), Medial–Lateral Stability Index (ML) (p < 0.01) with eyes open were observed after the experiment. The results show a significant deterioration in control group contrary to the experimental group where the improvement trend was observed. Moreover, the difference between the groups was observed in OSI parameter (p < 0.005) with eyes closed after the experiment. Conclusion The results obtained by the authors of the current study may support the thesis that educating coaches allows for better results in postural stability of child’s athletes. Nevertheless, this thesis requires further research, with particular emphasis on the age and gender of young athletes.

In these modern days teenagers are often interested in body-building. These hobbies can be used to generate interest in exercising in general and promote the development of muscle strength in particular. Middle school age is coincident with the end of the organism formation. At this time, the motor individuality of adult is finally formed. The deterioration of motor coordination with the intensive development of speed and speed-strength abilities is characterized for teenagers. There is a complex process of character and interests formation in life. The purpose of the article is – to demonstrate the influence of advanced method aimed at increasing the level of strength abilities for 12-13 year old boys. The research was performed from September 2020 to April 2021, experimentation facility was Gymnasium №107, Zaporizhia. It was attended by 57 boys aged 12-13 who were divided into experimental (n=29) and control (n=28) groups, all boys were classified in the main medical group. The advanced method has a clear applied orientation and is implemented mainly through the using of practical methods and forms, organization of lessons and aimed at implementing the variative principle. It includes: curriculum planning according to material and technical resources, staffing; age-sex characteristics of pupils, interests, provides succession and continuity between lessons; has a developmental character, applied orientation of the educational process and is aimed at forming a harmonious person. Important in organization of physical training lessons is the regular string of exercises focused on developing various strengths forms and their combination with other exercises. The obtained results showed that the indexes of strength training for 12-13 year old boys in the experimental group improve by 12.28%, and in the control group only by 6.42%. The positive influence of the elaborated method has been stated. The efficiency of the given method has been proved by the obtained data.

Studies on pain are generally conducted for two purposes: first, to study patients with pain who have physical changes due to nerve and muscle lesions, and second, to regain the appropriate kinematic post-pain pattern. The present study aimed to investigate the effect of pain on the coordination variability pattern and throw accuracy. Participants included 30 people with a mean age of 18-25 years who volunteered to participate in the study. Individuals were randomly divided into three groups of local pain, remote pain, and control group. Without pain, participants practiced and acquired skills in 10 blocks of 15 trials. In the retention and transition phase, which were associated with pain, in their respective groups, included 1 hour, 24- hour, and 1- week acquisition; they were re-tested twice in a 15-block trial, which was once with and without pain. The results revealed that pain did not affect the throwing accuracy (p = 0.469). Besides, in the phase of decreasing acceleration in throwing, movement variability pattern in the pain-related groups in the shoulder and elbow joints (p = 0.000), elbow and wrist (p = 0.000), were more than the painless groups. Based on the results, it can be said that the increase in variability in pain-related groups is due to the different strategies and patterns that individuals use to avoid pain. Also, despite the pain, the nervous system attempts to increase the variability find the least painful pattern of movement and reduces this variability over time and using a repetitive pattern.
