The paper presents results of neuromuscular system indices in male and female subjects aged between 20 and 28 who have been living in the North over 15 years and have different experience of applying cold procedures. Mean age of subjects is 22.8 years. Hand tremor parameters were recorded before and after local chilling procedure, on this basis body reaction in all experimental groups was compared. The control group is composed of participants who do not receive the experimental treatment. Group 1 composes of subjects who take chilling procedures less than 1 year. Group 2 composes of subjects who take chilling procedures more than 2 years. The effect of local chilling of changing neuromuscular system indices (tremorograms) is compared in 3 experimental groups in different seasons. During the experiment the statistical processing of obtained data is carried out, quasi-attractors squares are calculated for all experimental groups, phase portraits of tremor dynamics are created. Thus, order parameters in description of neuromuscular system under local chilling are identified.

Currently, Russian skaters are delivering incredible performances worldwide. In this regard, diverse social groups show increasing interest in this sport. Thus, professionals pay much attention to the coaching for win-win outcomes. It is especially important for single female skaters at the competitions where few hundredths of a point determine results of several participants from Russia, and at the same time dozens of points separate them and skaters from other countries on the podium. The aim of the research is to test the techniques of teaching multi-rotation jumps to female skaters aged 10-11. These techniques are part of training methodology, and they consider harmony, interconnection and versatility of sport training in general. These techniques include special exercises with the use of “Rotator” simulator. Materials and methods of the research. In our research, we used the review and analysis of scientific and methodological literature, pedagogical observations, pedagogical testing; pedagogical experiment, mathematical and statistical processing of the results. The experiment covered two groups of female athletes born in 2007-2008, with 8 people in each group. All the participants came from the «Zvezda» Center of Physical Culture and Sports of the North-Western administrative district of Moscow. Research results and discussion. Participants of the experimental group were performing the developed sets of exercises on general physical training, special physical training (including “Rotator” vestibular simulator) and training on skating rink during six months. The research revealed a significant increase in the technical and physical fitness of the participants of this subgroup. Conclusion. The developed set of “Rotator” simulator exercises, as well as complexes of auxiliary and special training exercises with increasing coordination complexity are effective in teaching multi-rotation jumps to female skaters aged 10-11 compared with the standard exercises performed in the control group.

Abstract Background In this research the biomechanical properties of a bone model was examined. Porcine ribs are used as experimental model. The objective of this research was to investigate and compare the biomechanical properties of the bone model before and after implant placement. Methods The bone samples were divided in three groups, Group 1 where ALL-ON-FOUR protocol was used during pre-drilling and placing the implants, Group 2 where ALL-ON-FOUR protocol was used during pre-drilling, and implants were not placed, and Group 3 consisting of intact bones served as a control group. Static and dynamic loading was applied for examining the model samples. Kruskal–Wallis statistical test and as a post-hoc test Mann–Whitney U test was performed to analyze experimental results. Results According to the results of the static loading, there was no significant difference between the implanted and original ribs, however, the toughness values of the bones decreased largely on account of predrilling the bones. The analysis of dynamic fatigue measurements by Kruskal–Wallis test showed significant differences between the intact and predrilled bones. Conclusion The pre-drilled bone was much weaker in both static and dynamic tests than the natural or implanted specimens. According to the results of the dynamic tests and after a certain loading cycle the implanted samples behaved the same way as the control samples, which suggests that implantation have stabilized the skeletal bone structure.

ABSTRACT Objective: This study aimed to evaluate the antimicrobial efficiency of PDT and the effect of different irradiation durations on the antimicrobial efficiency of PDT. Materials and Methods: Sixty freshly extracted human teeth with a single root were decoronated and distributed into five groups. The control group received no treatment. Group 1 was treated with a 5% sodium hypochlorite (NaOCl) solution. Groups 2, 3, and 4 were treated with methylene-blue photosensitizer and 660-nm diode laser irradiation for 1, 2, and 4 min, respectively. The root canals were instrumented and irrigated with NaOCl, ethylenediamine-tetraacetic acid, and a saline solution, followed by autoclaving. All the roots were inoculated with an Enterococcus faecalis suspension and brain heart infusion broth and stored for 21 days to allow biofilm formation. Microbiological data on microorganism load were collected before and after the disinfection procedures and analyzed with the Wilcoxon ranged test, the Kruskal-Wallis test, and the Dunn′s test. Results: The microorganism load in the control group increased. The lowest reduction in the microorganism load was observed in the 1-min irradiation group (Group 2 = 99.8%), which was very close to the results of the other experimental groups (99.9%). There were no significant differences among the groups. Conclusions: PDT is as effective as conventional 5% NaOCl irrigation with regard to antimicrobial efficiency against Enterococcus faecalis.

Abstract Purpose To evaluate whether the occurrence of chiasmal herniation coincides with visual field (VF) deterioration and to compare the course of VF defects in patients with and without radiological chiasmal herniation following treatment of pituitary adenoma. Methods This retrospective cohort study included 48 pituitary macroadenoma patients with chiasm compression, divided into three groups: Group 1 (N = 12), downward displaced optic chiasm and deteriorated VFs; Group 2 (N = 16), downward displaced optic chiasm; Group 3 (N = 20), control-group matched for tumour size and follow-up VFs, in mean deviation (dB). VFs were compared over time and a severity index, Chiasm Herniation Scale (CHS), for herniation based on radiological parameters was designed. Results After treatment, all groups showed improvement of VFs (Gr1: 2.97 dB p = 0.097, Gr2: 4.52 dB p = 0.001 and Gr3: 5.16 dB p = 0.000), followed by long-term gradual deterioration. The course of VFs between patients with and without herniation was not significantly different (p = 0.143), neither was there a difference in the course before and after herniation (p = 0.297). The median time till onset of herniation was 40 months (IQR 6 month-10 years) and did not significantly differ (p = 0.172) between the groups. There was no relation between VFs and the degree of herniation (p = 0.729). Conclusion Herniation does not appear to have clinical relevance with respect to VF outcome. The newly designed CHS is the first scoring system to quantify the severity of herniation and, in the absence of alternatives, may be useful to describe MRI findings to serve future added value in larger sized outcome studies.

Selection: 100 married pregnant women aged from 28 till 42 years (the first pregnancy of the first trimester, complications in the anamnesis isn't present) representing two groups on 50 people: 1) after artificial insemination (empirical group); 2) in a situation natural pregnancy (control group). The leading motives of pregnancy, types of the attitude towards themselves, pregnancies, to the child, people around, the prevailing installations in the sphere of the family relations, features of representation of future mothers about themselves and "the ideal parent" are defined by testing. Distinctions in all respects with women from control group are found. It is established that in vitro fertilisation the high level of readiness for motherhood according to its motivational characteristics is observed. Prevalence of constructive motives of pregnancy against concern in the health and aspirations to meet social expectations is revealed. The leading types of a gestational dominant are optimum and euphoric, the hypertrophied positive emotional background of pregnancy is observed. In the future of a bike probability the dependent relations with the child, preference of the sponsoring or authoritative style of family education. Revaluation of own parental qualities when comparing with image of ideal mother is observed. Results allow to carry women to the group of risk demanding psychological maintenance before and after the childbirth.

Background: Footwork training is important in coaching basic movements in badminton. This research aims to learn about the influence of footwork training on improving leg muscles strength. Methods: The study used a randomized pretest-posttest control group design. The participants consisted of 42 male badminton players of Universitas Pendidikan Ganesha, Bali, Indonesia, who split into two groups of footwork training (ten repetitions two sets (group 1) and five repetitions with four sets (group 2)). The coach gave the footwork exercise three times per week for 6 weeks to each group and measured the leg muscle strength using the dynamometer test. Results: The result of the within-group paired T-test before and after the training shows group 1 and group 2 (p<0.05). For group 1, the mean of leg muscle strength was 114.19±33.13 kg before the training and 183.19±33.56 kg after the training, with an increase of 60% (69 kg). On the other hand, for group 2, the mean score of leg muscle strength before the training was 113.05±31.30 kg and after the training was 141.10±34.91, with an increase of 25% (28 kg). The leg muscle strength difference between the groups before and after the training was tested using the independent T-test with a significant α=0.05. Comparing the differences of leg muscle strength for both the groups before the training was p= 0.90, and after the training was p=0.00.

The objective of the work: to study the changes of the functional activity of the endothelium and the plasma-coagulation link of hemostasis in women with chronic inflammatory processes of the internal genital organs (CIPIGO) with and without varicose veins of the small pelvis (VVSP).Materials and methods: 68 women with chronic inflammatory processes of the internal genital organs against the background of varicose veins of the small pelvis (group 1); 52 women with chronic inflammatory processes of the pelvic organs without varicose veins of the small pelvis (group 2); 30 practically healthy women (control group) were examined before and after the treatment. The age of women was between 18 and 45 years old. All the patients of the study groups received the treatment offered by us, which included a diosmine-containing phlebotropic preparation normoven, 500 mg twice a day in continuous mode and a donor of nitric oxide tivortin aspartatum, 5 ml 3 times per os for 14 days each month during six months.Determination of concentration of endothelin-1, prostacyclin was performed by immunoassay using a set of reagents from the firm “Biomediсa” (Austria); the determination of D-dimers in blood plasma was performed by latex-test of the firm “Organon-Tekhnika”.Results of workIn women with CIPIGO with and without VVSP, the increased production of endothelin-1, which has a pro-aggregate and pro-inflammatory effect, was determined. At the same time, the decrease of the synthesis of prostacyclin, which has anti-aggregant properties, was noted. In evaluating the indicators of coagulograms in patients of the studied groups, the propensity for hypercoagulation was revealed, as evidenced by an increase in the level of fibrinogen and a rise of index of the phospholipid-dependent coagulation tests. The decrease of the percentage of fibrinolytic blood activity and the increase in plasma concentration of the molecular marker of thrombophilia D-dimer can be considered as activation of intravascular coagulopathy and the presence of endothelial dysfunction.Conclusions: 1. Our studies found endothelial dysfunction and violations of the plasma-coagulation linkage of hemostasis in both studied groups. 2. After the performed treatment, the improvement of the functional activity of the endothelium and normalization of the main parameters of the plasma-coagulation linkage of hemostasis were observed.

The purpose of study was to find out the influences of two combinations of neuromuscular drills and asana practices on agility of basketball players.  To achieve the purpose of the study, thirty basket ball players with the age of 10 to 13 years from Navabisha Montessori School, Velachery, Chennai, Tamilnadu were selected as subject at random. The study was formulated as pre and post test random group design. The selected subject was divided into three equal groups. The group-1 (n=10, NMD-AP) underwent neuromuscular drills combined with asana practices. The group-2 (n=10, AP-NMD) underwent asana practices combined with neuromuscular drills and group 3 served as control group (n=10, CG). In this study, two training programme were adopted as independent variables and the agility was selected as dependent variable. It was tested by T test; scores recorded in seconds. The agility tested before and after the training period. The collected pre and post data was critically analyzed with apt statistical tool of analysis of co-variance (ANCOVA). The Scheffe’s post hoc test was used to find out pair-wise comparisons between groups. The result clearly proved that there was a significant improvement on agility in experimental groups than the control group.

Abstract The study aim was to compare the effects of a 7-week plyometric, strength and change of direction (COD) training program on basketball-specific performance measures in high-school players. Forty male players were randomly assigned to one of the four groups: plyometric (PG, n = 10), strength (SG, n = 10), COD (CODG, n = 10), and control group training (CG, n = 10). Two training sessions were performed at weekly intervals before basketball training. Performance of the counter movement jump (CMJ), Abalakov jump (ABKJ), 10 m zig-zag sprint, 20 m in line sprint (measurements at 10 and 20 m), and sit and reach flexibility test (SRFT) was assessed before and after the intervention. A 4 (group) × 2 (time) repeated measures analysis of variances (ANOVA) was conducted for each variable. Bonferroni post-hoc tests were used when the interaction was significant. Significant (all p < 0.05) time x group interaction was noted for SRFT, CMJ, ABK, sprint, and zig-zag 10 m, in favor of the experimental groups compared to the control group. However, improvements in physical fitness were similar between the three experimental groups. In conclusion, 7 weeks of specific plyometric, strength and COD training produced similar medium to large improvements in physical fitness of high-school basketball players.
