The study objective is to improve the structure and content of the annual training macrocycle for athletes aged from 15 to 16 years old in pankration, taking into account the specifics of their competitive performance.  Materials and methods. Theoretical analysis and generalization were used during work with literary sources on the problems of the research. Survey (questionnaire) was used for studying general approaches to the structure and content of young athletes’ training (aged from 15 to 16 years old) in pankration. There were also analyzed official programs for experienced pankration athletes which are used in Ukraine. Pedagogical experiment was held during September 2018 – July 2019. Its total duration was 10 months and 906 hours. Two identical six-month training macrocycles were performed. The control (21 athletes) and experimental (22 athletes) groups were formed.  Results. It was more effective for the development of technical and tactical actions and special physical fitness of young athletes aged from 15 to 16 years old. It was confirmed by significant intra-group increases in indicators of athletes’ preparedness (p≤0.05-0.01). The total number of significant changes in the experimental group (p≤0.05-0.01) during the first and second stages of the experiment was 12 of 13 indicators, and their values were higher than in the control group. In the control group, significant positive changes (p≤0.05-0.01) were found in 6 indicators during the first stage of the experiment and 8 – during the second one. After the second stage of the experiment athletes of the experimental group performed about half of the technical and tactical actions with a higher level of stability, economy, efficiency in various situations during sparring matches.  Conclusions. An experimental program made it possible to achieve an earlier deployment of adaptation processes to the specific physical activity available in training and competitive activities in pankration.

The reproductive traits of sows are of paramount importance in the production of high-quality pork. The world experience of pig farming shows the need to solve first of all the feed problem. Diets unbalanced in the content of vitamins restrain the manifestation of genetically inherent high prolificacy of sows. The purpose of the research was to study the influence of feeding the vitamin feed additive “LipoCar” on the reproductive traits of sows and the biochemical parameters of blood serum. The results of research on the introduction of vitamin feed additive “LipoCar” into the diet of pregnant sows have been presented in the article. The experiment has been carried out in the production conditions in JSC “Linevsky pedigree farm” on sows of Large White breed. Pregnant sows have received a basic diet, balanced for all the normalized elements of nutrition. Sows of the experimental group in the composition of the basic diet fed the feed additive “LipoCar”. The dosage of the drug “Lipocar” was 2,1 g/head/day. “Lipocar” has been fed for 20 days. The total duration of the experiment was 3 months. When introducing the vitamin feed additive “LipoCar” into the main diet of sows in the second half of pregnancy the increase in the number of piglets in the litter by 1,6-6,8 % and the weight of the litter – by 5,6-56,2 % (P ≤ 0,001) have been revealed in comparison with the control group of animals. There was a higher content of carotene in the blood serum of sows of the experimental group by 50,0 % (P ≤ 0,01), vitamin A - by 48,7 % (P ≤ 0,05), and total protein – by 4,9 % (P ≤ 0,05).

The study objective is to compare the outcomes of surgeries performed via the transciliary supraorbital approach and traditional lateral supraorbital approach in patients with suprasellar meningiomas. Material and methods. The experimental group included 17 patients (8 males and 9 females aged between 38 and 67 years (mean age 48.7 ± 5.9 years)) with meningotheliomatous meningiomas (size between 15 and 46 mm (mean size 24.5 ± 5.7 mm) that underwent surgery via the transciliary supraorbital approach. All surgeries were performed by one surgeon. The control group included 20 patients (10 males and 10 females) that underwent surgery via the lateral supraorbital approach. These surgeries were also performed by one surgeon. The 2 groups were matched for size and location of meningiomas. We compared the extent of surgery, frequency of complications, severity of cosmetic defects, and other parameters between the groups. Preoperative examination, microsurgical removal of the tumor, anesthesia, and postoperative management were the same in both groups. Results. We observed no differences in the extent of surgery, frequency of complaints, complications, and neurological status between participants in the experimental and control groups. There were no deaths in either group. Patients that underwent surgery via the transciliary supraorbital approach had lower blood loss than those who underwent surgery via the lateral supraorbital approach (145 ± 18 mL vs 186 ± 24 mL). The duration of surgery was also lower in the experimental group than in the control group (145 ± 24 min vs 167 ± 32 min). Cosmetic outcomes were evaluated using the Cosmetic Visual Analogue Scale. Participants in the experimental group had higher score (>90) than controls (2 patients reported scores of 70 and 80). Possible negative effects of the transciliary supraorbital approach include the risk of scarring in the eyebrow area, skin numbness in the frontal area, paralysis of the frontalis muscle, and the need for more accurate preoperative markings using neuronavigation. Conclusion. In general, the therapeutic effect of surgeries via the transciliary supraorbital and lateral supraorbital approaches do not differ. However, the use of the transciliary supraorbital approach allowed smaller incisions (in both skin and dura mater) and smaller trepanation holes (and as a result minimal displacement of brain structures during surgery). It also ensured lower blood loss and duration of surgery and improved the cosmetic effect. The decision on the surgical approach should be based on tumor characteristics with the consideration of patient’s opinion.

The aim of this study was to determine the effects of plyometric training on sprint abilities. Young basketball players (N=33, Age=15-16) from OKK "Stari Ras" and OKK "Novi Pazar" from Novi Pazar were divided into two groups: an experimental group (EG, n=16; BH=185.45±8.75cm; BM=76.87±11.51kg) with training experience (TE=4.69 ±1.40 years) and a control group (CG; n=17; BH=184.16±6.93cm; BM=76.87±11.51kg) with training experience (TE=5.53±3.18 years). The EG was made up of the players from basketball team OKK "Stari Ras", who in addition to basketball trainings also took part in plyometric training. The CG was made up of the players from basketball team OKK "Novi Pazar", who at that time only took part in basketball trainings. To assess their sprint abilities, three tests were used: Sprint Speed at 5m (S5m), Sprint Speed at 10m (S10m), Sprint Speed at 20m (S20m). The measurement was done with the help of the photocells "Microgate", a parameter which was monitored and the processed time was read in 1/100s. The experimental program lasted for 10 weeks (2x per week). To determine the effect of plyometric training on the sprint abilities of young basketball players, the analysis of covariance ANCOVA was used. The results showed that the EG group achieved significantly greater progress than the CG group on the tests: S5m and S20m. There was no difference between the EG and CG group on the S10m test. Based on these results we concluded that plyometric training has positive effects on the development of sprint abilities in young basketball players.

  Carlos Alberto A 83 sujetos de nueve modalidades deportivas se aplicó un plan de desarrollo de la potencia por Modelamiento ejecutado por los preparadores físicos (PF) del Team Medellín, del INDER (Instituto Municipal de Deportes de Medellín). La intervención se realizó para todos los deportistas, en el gimnasio ubicado en la Unidad Deportiva Atanasio Girardot (UDAG) de la ciudad de Medellín. Los 83 sujetos se distribuyeron aleatoriamente empleando números aleatorios (62 al grupo experimental (GE) y 21 al grupo control (GC)). De estos 41 fueron masculinos (49.4%), prioritariamente del estrato socio económico dos (56 para el 67.5%), con un promedio edad de 15.9 años (± 3), una masa corporal media de 53.2 kg (± 18.8) y una talla de 144.5 cm (± 53.7). Para la medición de la potencia se empleó un encoder lineal T-Force® (Dynamic measurement system), una cabina Smith, un sistema mecánico de graduación del ángulo de la rodilla en la media sentadilla. Para la medición se capacitaron y estandarizaron tres evaluadores. El procedimiento de medición empleó cargas progresivas hasta obtener la máxima potencia. Se aplicó una planeación de acuerdo a lo estipulado en Modelamiento, concentrando la componente de fuerza-potencia. El plan de entrenamiento para el grupo experimental duró ocho semanas, dos veces por semana, iniciando tres microciclos básicos de potencia (con cargas de baja intensidad, 30%), luego dos microciclos de fuerza-potencia (intensidad media, 40-50%) y terminando con dos microciclos de potencia-velocidad (intensidad media, 50%). Los resultados mostraron un incremento significativo (p<.05) de la potencia máxima (14% con relación al pre test) del grupo experimental, mientras que en el grupo control (que realizó actividades deportivas sin entrenamiento de potencia) no mostró incrementos significativos. Se llegó a la conclusión de que, al aplicar un plan por Modelamiento basado en cargas bajas por carácter del esfuerzo, es decir, realizando siempre menos repeticiones de las posibles, a una alta velocidad se mejora significativamente la potencia de atletas jóvenes.  Abstract. A modelating plan for development was implemented to 83 subjects from nine different sport fields by the physical trainers from Team Medellín, by INDER (Local sports institution of Medellín). The completion was developed with all athletes, in the gymnasium located in the Atanasio Girardot Sport Complex in Medellín. The 83 subjects were distributed ramdonly using shuffle numbers (62 to the experimental group and 21 to the control group). From those 41 were male (49.4%), mainly from number two social standing, according to Colombia establishments (56 meaning 67.5%), with an age average of 15.9 years old (± 3), 53.2kg of body weight and 144.5cm height (± 53.7). The T-Force® (Dynamic measurement system) and the Smith cabin (A adjustable mechanical system for the knee angle) were applied to the power measurement to which three evaluators were trained for. This measuring procedure used progressive charges until the maximum power capacity was obtained. Due to Modelating theories a specific plan was applied, with strength-power component as the focused variant. The training plan for the experimental group lasted eight weeks, twice a week, beginning with three basic power micro cycles (with low intensity charges, 30%), then two strength-power micro cycles (middle intensity, 40-50%) and two power-speed micro cycles (middle intensity, 50%) at last. The results show a maximum power significant growth (p<.05, 14% compared with the pre-test) in the experimental group, since the control group (which did sports without power training) remained standardized. As a conclusion, applying a modelating plan based on low charges in term of effrort, always attaining less repetitions than the possible amount in higher speed, increases significantly the power in young athletes.

Introduction. The number of patients with cystic formations of the pancreas has increased significantly recently. Some of the patients need open or minimally invasive surgery. The implementation of ERAS (Enhanced recovery after surgery) protocols has been proved to be effective in orthopedics, bariatric and colorectal surgery. However, safety and feasibility of implementation of accelerated rehabilitation protocols in patients with cystic formations of the pancreas who underwent resection and resection-drainage interventions have not been sufficiently studied.The aim of the study was to assess the effectiveness and safety of implementation of the developed accelerated rehabilitation protocol in patients with cystic pancreatic formations who have undergone resection and resection-draining interventions.Material and methods. This research is a retrospective-prospective, single-center study. The study included 110 patients with cystic formations of the pancreas of various etiologies. All patients were divided into two groups: the control group consisted of 55 patients, their perioperative management was carried out according to standard protocols, and the experimental group consisted of 55 patients, their perioperative management was carried out according to the accelerated rehabilitation protocol developed in the clinic. All patients included in the study were exposed to surgery: resection and resection-draining interventions in various modifications were performed.Results. Patients in the studied groups were comparable by gender, age, body mass index, ASA score, preoperative albumin level. No statistically significant differences were found in the duration of the operation, intraoperative blood loss, or the frequency of blood transfusions. The overall complication rate was significantly lower in the experimental group compared with the control group (38,2% versus 58,2%, p = 0,03). Postoperative recovery of the gastrointestinal function was also faster in the experimental group. Thus, in the experimental group, the average time to the gas discharge was 2,1 0,8 days; in the control group - 3,1 1,1 days (p = 0,01); the average time to the first stool was 3,2 1,9 and 4,2 1,2 days, respectively (p 0,001). The total duration of the postoperative hospital bed per day was significantly lower in the experimental group compared with the control group (11,8 7,7 vs 16,2 13,2 days, respectively, p = 0,02).Conclusions. The study demonstrated safety and effectiveness of implementation of accelerated rehabilitation protocols in patients with cystic pancreatic formations who have undergone resection and resection-draining interventions. Implementation of the protocols allows reducing the duration of the postoperative hospital bed per day, incidence rate of complications, and also accelerating the gastrointestinal function recovery.

The article presents the results of studying the effect of stocking density on the productivity of pigs while rearing.The research was conducted in PE "Kalynsky Klyuch" p. Kalyna Kamyanets, Podilskyi district, Khmelnytsky region. The scientific and economic experiment was performed by the method of analogous pairs, with a total duration of 73 days. The experiment was performed on young pigs for rearing. Animals were selected into groups based on age, life weight, health status, sex, fatness and growth energy during the preparation period. Four groups of pigs were formed. During the experiment, the animals were weighed, feed intake was taken into account, and their health was monitored. The productivity of young animals was determined according to the monthly individual weighing of animals, which were carried out 1-2 hours before morning feeding, and feed costs - based on group accounting. All data obtained in the experiment were processed biometrically. According to the results of the research, it was found that the most optimal is the density of pigs at the rate of 2.58 heads / m2. Analysis of the dynamics of live weight of experimental animals showed that with the same weight of piglets since the beginning of the rearing period and till the end of it, the weight of the animals differed significantly. The highest average live weight was recorded in the second experimental group, where there are 2.58 heads per 1 m2 of pigsty - 27.4 kg, and the lowest in the fourth experimental group, with a livestock density of 3.42 heads / m2, - 25.4 kg. The animals of the first control group (1.75 heads / m2) have a live weight of 27.3 kg, and the animals of the third experimental group (3.42 heads / m2) - 4.0% less. For farms in the fodder with natural and climatic conditions of the region, ready to use fodder as efficiently as possible and to obtain the maximum productivity of 4-breed hybrid piglets during the rearing period, we suggest using the livestock density at the level of 2.58 heads / m2 of the pigsty. Taking the recommendations into account is the way to achieve successful results in pig farming.

The article presents the results of bulls control slaughter, morphological and varietal composition of the pulp of carcasses, depending on the duration of the production cycle and the level of concentrates in the diet. In the gobies of the control group, the total duration of the production cycle was 18 months (546 days), with a specific gravity of concentrates in the rations of 40 % in the experimental group – 16 months (482 days) – 50 %. The suckling period of calves in the control group was 210 days, in the experimental group – 182 days, rearing – 186 and 165 days, respectively, intensive final fattening – 150 and 135 days. The differences obtained both in the pre-slaughter live weight and in the weight of the paired carcass were 1,9 and 3,4 kg, respectively, without a significant difference between the groups. The superiority of bulls of the experimental group over the control group was established according to the leading studied indicators of the morphological composition of carcasses, except the mass of bones, cartilage, and tendons. Differences in the mass of the pulp in favor of the calves of the experimental group were 5,1 kg, the coefficient of meat content was 0,21 units, the ratio of the edible part to the inedible part in the carcass was 0,26 units. All other things being equal, from the bulls of the experimental group, a higher mass of pulp of the highest grade was obtained by 4,9 kg or 2,2 %, of the first grade – by 6,4 kg or 1,8 %. The yield of secondgrade pulp was higher in the carcasses of gobies of the control group by an average of 6,2 kg or 4 %. Thus, both groups of bulls showed high slaughter weight and slaughter yield, with insignificant intergroup differences. However, due to the shorter duration of the production cycle of growing and fattening, it turned out to be preferable to use beef production technology from bull calves of the experimental group.
