Posture Stability

The purpose of the study is to establish changes in the indicators of postural stability of the body of ballroom dancers under the influence of training loads and competitive activity. Materials and methods. With the help of a force plate with biological feedback “Stabilan 01-2” the interaction of athletes with the support was registered, in particular the movement of the common center of pressure of the feet on the support. The standard (with open eyes) and complicated (with closed eyes) Romberg tests were used. The indicators were being recorded for 30 seconds at rest, as well as under the conditions of visual control before and after a typical training session, before and after competitions. The obtained data in two experimental situations were compared with initial data at rest. In total, 25 couples were studied. Couples aged 18-19 years old were studied in the amount of 15 couples, training at the stage of maximum realization of individual capabilities, and 10 couples at the age of 14-15 years old, training at the stage of specialized basic training. All the participants actively train and regularly participate in competitions. Results and discussion. Studies have shown that in the tests, which were carried out, there were obvious differences in posture stability associated with the influence of training and loads used in them. The analysis of the data proved that the test results indicate the regular differences in the indicators of posture stability in accordance with the sports experience of athletes after a training session in comparison with the initial ones (in the so-called state of rest). Athletes aged 18-19 years have a significantly higher quality indicator of balance function than people aged 14-15 years (p <0.01), which in our opinion is explained by dancing experience and adaptive changes that occur in the athlete’s body, because, according to researchers, the higher the specified indicator is, the correspondingly higher the human statokinetic stability is. A separate analysis of female and male representatives indicated less frontal scattering in male athletes aged 18-19 years old compared to girls of this age group (p <0.05). The area of the ellipse when conducting the test with closed eyes also significantly differed in boys from girls, regardless of dancing experience (p <0.05). Comparing the stability indicators of girls in dancing shoes and without them, we stated a regularity of a decrease in the quality of body balance from “more to less”: from maintaining a classical posture with open eyes to the same posture in dancing shoes in a test with closed eyes. The results of the correlation analysis between the indicators of static-dynamic body stability and the sports result of more experienced girl-partners allowed to establish the existence of a connection (r=0.61), which reflects the tendency according to which, with an increase in sports performance, the indicators of the oscillation amplitude of the center of body pressure on the support, its linear velocity of movement, the length of this trajectory both in the sagittal and in the frontal planes, the area of the ellipse decrease, which complements and confirms the data of other authors [6, 10]. Conclusion. Thus, according to the results of the study, it was found that the visual analyzer plays an important role in maintaining balance, which can be seen in the test results of both age groups. Moreover, the greater influence of visual control on the postural stability was stated in girl-partners than in boy-partners. It was also found that the quality of the balance function before and after competitions in older dancers did not change, while in less experienced dancers it decreased by almost 2%, and a comparison of the changes that occurred under the influence of training loads and competitive activity made it possible to establish the presence of adaptation to competitive loads, which manifested in a very significant improvement in the work of systems of vertical posture support in all age groups

Introduction. An osteopathic examination determines the rate, the amplitude and the strength of the main rhythms (cardiac, respiratory and cranial). However, there are relatively few studies in the available literature dedicated to the influence of osteopathic correction (OC) on the characteristics of these rhythms.Goal of research — to study the influence of OC on the rate characteristics of various rhythms of the human body.Materials and methods. 88 adult osteopathic patients aged from 18 to 81 years were examined, among them 30 men and 58 women. All patients received general osteopathic examination. The rate of the cranial rhythm (RCR), respiratory rate (RR) heart rate (HR), the mobility of the nervous processes (MNP) and the connective tissue mobility (CTM) were assessed before and after the OC session.Results. Since age varied greatly in the examined group, a correlation analysis of age-related changes of the assessed rhythms was carried out. Only the CTM correlated with age (r=–0,28; p<0,05) in a statistically significant way. The rank dispersion analysis of Kruskal–Wallis also showed statistically significant difference in this indicator in different age groups (p=0,043). With the increase of years, the CTM decreases gradually. After the OC, the CTM, increased in a statistically significant way (p<0,0001). The RCR varied from 5 to 12 cycles/min in the examined group, which corresponded to the norm. After the OC, the RCR has increased in a statistically significant way (p<0,0001), the MNP has also increased (p<0,0001). The initial heart rate in the subjects varied from 56 to 94 beats/min, and in 15 % it exceeded the norm. After the OC the heart rate corresponded to the norm in all patients. The heart rate and the respiratory rate significantly decreased after the OC (р<0,0001).Conclusion. The described biorhythm changes after the OC session may be indicative of the improvement of the nervous regulation, of the normalization of the autonomic balance, of the improvement of the biomechanical properties of body tissues and of the increase of their mobility. The assessed parameters can be measured quickly without any additional equipment and can be used in order to study the results of the OC.

AbstractTennis is one of the most popular and widely played sports enjoyed by players of different age groups and genders as a profession as well as a mode of recreation. A novel method, PETTLEP imagery combines both conventional and non-conventional style of training of an athlete and improves one’s performance. This study aimed to analyze the tennis service performance of junior tennis players based on PETTLEP imagery training. Forty-four junior male tennis players (Mage=13.22 years, SD=0.42) were selected for the study. The investigator handed over the MIQ-R questionnaire to all the participants in which they scored 16 and above points as per previous research. The participants were equally divided (n=11) into three experimental groups (E1, E2, and E3) and a control group. The service performance outcomes of all the players were compared before and after a training session. The three experimental groups were assigned with service-specific training, service-specific training combined with PETTLEP imagery training, and PETTLEP imagery training alone, respectively, for three days per week for 12 weeks. They were tested on their service accuracy based on the International tennis number (ITN) manual on-court assessment test. The data were assessed for normality and analyzed using non-parametric methods to reveal main effects (each training method alone) as well as to calculate the combined effect of PETTLEP and service-specific training. Certain significant improvements in tennis service were observed with service-specific training alone. Though it marginally outperformed the PETTLEP imagery method, the most improved services were observed with both PETTLEP and service-specific training utilized together. This implies an additive effect when both methods are used together.

The aim of this research paper was to examine the voice quality of sports coaches using the objective (acoustic) method. A total of 28 sports coaches (mean age 28.58, SD=5.08), from the City of Zagreb participated in this research. Recordings of the phonation of the vowel /a/ before and after one training session were obtained and analyzed using the PRAAT Program. Mean, minimal and maximal values of fundamental frequency, shimmer, jitter and harmonics-to-noise ratio were observed. The statistical analyses showed no statistically significant difference in acoustic voice quality of male and female coaches before and after the training session, or between male and female coaches. However, intra-individual differences among participants were observed, which may be significant in terms of their potential to affect the quality of their voices in the future.

Due to the fact that milk has a short shelf life, the issue of its freezing and long-term storage in the frozen state is relevant. A study was conducted on the effect of freezing on the milk quality after its defrosting of cows-mothers and cows-daughters of Red-Motley breed. As a result, it was established how milk quality indicators to change after five months of storage in a frozen state in cows of two age groups. A high correlation was established between quality indicators before and after freezing. The influence of the “freezing” factor on milk quality indicators was recognized statistically significant, the “generation” factor – not significant.

This study aimed to examine the effect of changes in status, employee engagement, and the utilization of information technology on the quality of financial reporting. Analysis of variance (ANOVA) was used to examine changes in the status of Bogor Agricultural University. Moreover we employ a multiple regression analysis to examine the effect of employee engagement and information technology in performance financial of report.  In addition, Ultrecht Work Engagement Scale (UWES) was used to examine the financial human resource mapping. The results of ANOVA test showed that there was no significant difference of the financial management of Bogor Agricultural University before and after the implementation of Public Service Board (BLU). Furthermore, multiple linear regression test results showed that the factors that affect the performance of financial reports are employee engagement and use of information technology. However, it is found that the factor that really affects the performace of financial reports is the use of information technology. Finally, the test results of the mapping showed that employee engagement of human resources staff of Bogor Agricultural University are in medium position indicating that it needs to be maintained and improved.

Adolescent judo athletes who train in tropical climates may be in a persistent state of dehydration because they frequently restrict fluids during daily training sessions to maintain or reduce their body weight and are not given enough opportunities to drink.Purpose:Determine the body hydration status of adolescent judo athletes before, immediately after, and 24 h after (24H) a training session and document sweat Na+ loss and symptoms of dehydration.Methods:Body mass and urine color and specific gravity (USG) were measured before, after, and 24 h after a training session in a high-heat-stress environment (29.5 ± 1.0°C; 77.7 ± 6.1% RH) in 24 adolescent athletes. Sweat sodium loss was also determined. A comparison was made between mid-pubertal (MP) and late pubertal (LP) subjects.Results:The majority of the subjects started training with a significant level of dehydration. During the training session, MP subjects lost 1.3 ± 0.8% of their pretraining body mass whereas LP subjects lost 1.9 ± 0.5% (P < .05). Sweat sodium concentration was 44.5 ± 23.3 mmol/L. Fluid intake from a water fountain was minimal. Subjects reported symptoms of dehydration during the session, which in some cases persisted throughout the night and the next day. The 24H USG was 1.028 ± 0.004 and 1.027 ± 0.005 g/mL for MP and LP, respectively.Conclusions:Adolescent judo athletes arrive to practice with a fluid deficit, do not drink enough during training, and experience symptoms of dehydration, which may compromise the quality of training and general well-being.

Working memory (WM) training with the N-Back task has been argued to improve cognitive capacity and general cognitive abilities (the Capacity Hypothesis of training), although several studies have shown little or no evidence for such improvements beyond tasks that are very similar to the trained task. Laine et al. demonstrated that instructing young adult participants to use a specific visualisation strategy for N-back training resulted in clear, generalised benefits from only 30 min of training (Strategy Mediation Hypothesis of training). Here, we report a systematic replication and extension of the Laine et al. study, by administering 60 younger and 60 older participants a set of WM tasks before and after a 30-min N-back training session. Half the participants were instructed to use a visualisation strategy, the others received no instruction. The pre-post test battery encompassed a criterion task (digit N-back), two untrained tasks N-back tasks (letters and colours), and three structurally different WM tasks. The instructed visualisation strategy significantly boosted at least some measures of N-back performance in participants of both age groups, although the strategy generally appeared more difficult to implement and less beneficial for older adults. However, the strategy did not improve performance on structurally different WM tasks. We also found significant associations between N-back performance and the type and level of detail of self-generated strategies in the uninstructed participants, as well as age group differences in reported strategy types. WM performance appeared to partly reflect the application of strategies, and Strategy Mediation should be considered to understand the mechanisms of WM training. Claims of efficient training should demonstrate useful improvement beyond task-specific strategies.

Pregnancy is a period of both hormonal and non-hormonal overall change in the body. Emotional instability is commonly experienced by women during this period. However, this somewhat complex issue is often not addressed optimally. Pharmacological therapies using CPZ and lithium are often administered, but they have effects for the body. Therefore, there is a need to administer non-pharmacological therapy that has minimum side effects. This research aims to increase the healthy energy within the body using Pranic Healing, which is measured by the Bio-Well GDV camera. This research employed the pretest-posttest method on two groups (treatment and control) using the Randomized Controlled Trial design. Pranic Healing therapy was performed for 30 minutes once a week for 3 weeks, while GDV measurement was performed once a week for 4 weeks. Paired t-test results for Pranic Healing on emotional pressure showed p-value of 0.0001 (<0.05) for posttest2 and p-value of 0.005 (<0.05) for posttest3. Meanwhile, the control group did not indicate any changes in emotional stress both before and after treatment. It is found that Pranic Healing as measured using a bio-well GDV camera is capable of improving health energy within the body by relieving emotional stress experienced in trimester III primigravida.
