Very high results, the achievement of which is possible only with long systematic train-ing with the use of large and sometimes excessive physical activity characterizes modern sports. The preparation process from beginner to master of sports takes an average of 5–10 years. During this time, the athlete must develop and improve special physical and mental qualities, as well as master certain motor skills specific to this sport. Therefore, children's and youth's organisms of athletes are subject to increased loads, especially in classes that develop endurance. But not always physical activity contributes to the strengthening of the body, sometimes excessive loads, especially with the wrong approach, lead to complications from the cardiovascular system, in particular, to changes in heart rate. Therefore, the issue of adapting the functions of the heart of young athletes to muscle loads becomes increasingly important. The purpose of the work was to study the activities of the cardiovascular system of skiers-riders in the preparatory period of the one-year cycle. Currently, various methods of functional diagnosis of the cardiovascular system are used. We considered the results obtained during electrocardiographic examination of skiers-riders. We investigated electrical activity of the heart and presented model characteristics according to the considered indicators.

The overall orientation of the research problem is focused on the physical activity level of the participants from the aspect of different intensities of motor engagement and their impact on morphological characteristics and motor skills with an intention of determining whether there are statistically significant differences between groups. In a sample of 103 students, aged between 18 and 20 years (18.9 ± 0.4), the female students were divided into three subsamples according to the level of physical activity: highly active, active and inactive. The study which was conducted had a transversal character. The data obtained in the survey were analysed using the univariate (ANOVA) and multivariate (MANOVA) statistical methods. The motor skills mere monitored by the use of the Eurofit Test Battery (wide-angle seated forward bend, standing long jump, pull-up endurance, 10 x 5m shuttle run and endurance shuttle run- beep test). The following morphological characteristics were considered: height, weight, body mass index, percentage of muscular mass and fat mass, as well as waist circumference. The obtained results indicate the existence of statistically significant differences between the % body muscle mass´ groups (p < 0.05) and motor skills parameters (sit and reach, p<0.01; standing broad jump, bent arm hang, 10x5m shuttlerun, beep test, p<0.001) of participants according to physical activity level. In conclusion, participants with a high level of physical activities have higher average values than the participants with light level of physical activities when considering the variables for assessing pliability, strength and agility.Resumen. La orientación general del problema de investigación se centra en el nivel de actividad física de las participantes desde el aspecto de diferentes intensidades de compromiso motor y su impacto en las características morfológicas y habilidades motrices con la intención de determinar si existen diferencias estadísticamente significativas entre los grupos. En una muestra de 103 alumnas, con edades comprendidas entre los 18 y 20 años (18,9 ± 0,4), las estudiantes fueron divididas en tres grupos de acuerdo con el nivel de actividad física de cada uno: muy activas, activas e inactivas. El estudio llevado a cabo tuvo un carácter transversal. Los datos obtenidos mediante cuestionarios fueron analizados utilizando un análisis de la varianza (ANOVA) y un análisis multivariante de la varianza (MANOVA). Las habilidades fueron controladas mediante la batería Eurofit y para las características morfológicas, se midió la altura, peso, índice de masa corporal, porcentaje de masa muscular, masa grasa y la circunferencia de la cintura. Los resultados obtenidos indican la existencia de diferencias entre los grupos estudiados respecto al % de masa muscular (p <0.05) y las habilidades motrices (flexibilidad-inclinación hacia adelante, p<0.01; salto de longitud a pie, fuerza resistencia mediante flexión de brazos, 10 x 5 m carrera de ida y vuelta y Beep Test, p<0.001) de los participantes según el nivel de actividad física. En conclusión, las participantes con alto nivel de actividad física tienen mayores valores de habilidad motriz que las participantes que el resto en función de las variables flexibilidad, capacidad aeróbica, fuerza y agilidad.

Regular exercise during school hours is encouraged; however many children and adolescents fail to meet the recommendations during this time. Extracurricular activities may be a more appealing way for youth to achieve guidelines, and it is recommended that they attend two sessions each week. The aim of the study was to assess the influence of participation in a national physical activity program accompanied by nutritional education for trainers on the risk of obesity and body composition in a nationwide sample of boys and girls, after one year of intervention. The #goathletics Study was conducted in a group of 1014 adolescents aged 12–13: 507 individuals for the Athletics for All program (210 boys, 297 girls) and 507 pair-matched individuals not participating in any physical activity program (matching including: gender, age, city of residence). The body mass (kg), Body Mass Index (BMI) (kg/m2), waist circumference (WC) (cm), waist-to-height ratio (WHtR) (-) and body composition (%) (measured using bioelectrical impedance method) were compared in a gender-related sub-groups using t-Student test (for parametric distributions) or Mann-Whitney U test (for nonparametric distributions) and chi2 test (for the share of sub-groups). After one year of intervention, lower body mass percentile, BMI percentile, WC, WHtR and fat mass share, higher muscle mass share, as well as lower frequency of overweight/obesity and abdominal fat distribution were observed both for boys and girls participating in the physical activity intervention compared to the pair-matched controls. The after-school physical activity program accompanied by nutritional education for trainers may be a highly effective method for reducing the risk of obesity both for boys and girls, as regular participation is ensured.

Amsinckia is a serious weed in the wheat growing areas of north-western Victoria. It is successful in the inter-crop pastures, based upon barrel medic, because it grows faster than barrel medic in the cooler months of May to August. In addition, the rapid growth in height associated with the change from rosette to elongating phases ensures a height advantage over the pasture species when the flush of pasture growth does commence. Seed production by each Amsinckia plant is very high, and for this reason any competitive restriction obtained in one year is not necessarily reflected in the establishment phase of the next. Subterranean clover c.v. Clare is more competitive than barrel medic and was able to eliminate Amsinckia from the sward in two years. However it has only limited application in the pastures of north-western Victoria. A mowing treatment was carried out at the commencement of Amsinckia flowering, for this coincides with the beginning of rapid pasture growth. Regrowth produced a reversal of height relationships within the pasture and enabled barrel medic to shade Amsinckia BJ this treatment growth and seed production of Amsinckia were reduced by 99 per cent within the one season.

Abstract Background. The purpose of the study was to realize the priorities in physical, technical and tactical training for junior football players. Moreover, preparing of the content was intended to optimize the use the most efficient methods and means for increasing the efficiency of speed and skill during the training and games. Objectives. Data were collected from 18 junior football players, with ages ranging from 14-15 years, members of the ACS Unirea (C) Tritenii de Jos team. The subjects were tested three times during the whole training stage, pre, middle and post-training examinations being performed. The three examinations consisted of 5 tests each: 50-meter sprint, standing long jump, 2000 meter running, maintaining the ball in the air and leading the ball through markers. Methods. Specific methods for developing the speed used in the study are based on repetitions (specific efforts at maximum or submaximal speed, under usual, relieved, severe conditions), on various efforts and intervals. Skill development methods took into account the complexity of coordinating action movements and the spatial, temporal, and motion force precision. For developing motor skills, the authors used the interval and circuit training. Results. All the participants attained higher levels of performance, both at the second and third examination, on each of the 5 tests. Data collected were analyzed using the One –Way ANOVA statistical procedure, which compares the results obtained by one single group of subjects. This procedure revealed, at a significant level of confidence, that the mean of the performance enhancement reached 50 percents along the one-year training stage. Conclusions. The research has shown that, by giving a more significant share of the best methods and means for developing the speed and skill in the physical training of junior footballers, the increase in the performance of these motor skills is significant.

The condition of the cardiovascular system is one of the important criteria for assessing the impact of sports training on the human body. According to the indicators characterizing the state of the cardiovascular system, it is possible to trace the changes associated with fluctuations in the level of training, as well as to identify signs of overload as early as possible. The study of adaptive reactions of the cardiovascular system in athletes under physical activity is an important indicator for sports practice. The purpose of the study was to investigate the quantitative criteria for assessing the state of the cardiovascular system and approaches to correct the functional state of qualified athletes specializing in table tennis. Materials and methods. Studies of heart rate variability, quantitative and qualitative indicators that sufficiently reflect the autonomic functions of the body were used in order to assess the state of autonomic regulation in highly qualified athletes. Systematic physical activity causes a significant restructuring of the cardiovascular system and leads to morphofunctional changes in the mechanisms of the heart. Depending on the autonomic regulation of heart rhythm, there are different ways of myocardial adaptation processes. The balance of sympathetic and parasympathetic links of autonomic rhythm regulation is reflected in the activation of the left ventricle. Results and discussion. Adaptive changes of the cardiovascular system to competitive and training loads in the competitive period in qualified athletes are characterized by a significant decrease in heart rate (from 84.75±1.74 beats / min to 74.8±0.38 beats / min). In addition, a significantly faster process of restoring heart rate was established after exercise in the group of qualified athletes, compared with athletes of the category 1 at 4 (p >0.05) and 5 (p >0.05) minutes, respectively. According to the indicators of autonomic regulation of heart rhythm, activation of the parasympathetic link prevails in athletes of the category 1 in comparison with qualified athletes activation (according to high-frequency component, p <0.05). Significantly higher rates of individual parts of the body compared to low-skilled athletes were found out: the hormonal system (the indicator responsible for the hormonal part of the body – very low-frequency component) and the nervous system (indicators of the sympathetic nervous system – low frequency component). There are significantly higher values of the magnitude of the heart rate spectrum and high-frequency component at p <0.05, which indicates a higher power of all units of the parasympathetic regulation in the category 1 in relation to masters of sports and candidates masters of sports. Conclusion. Systematic physical activity causes a significant restructuring of the cardiovascular system and leads to morphofunctional changes in the mechanisms of the heart. Depending on the autonomic regulation of heart rhythm, there are different ways of myocardial adaptation processes. The balance of sympathetic and parasympathetic links of autonomic rhythm regulation is reflected in the activation of the left ventricle. The analysis showed that the spectral characteristics of heart rate variability significantly differ between groups of athletes with different dominance that are observed only in terms of high-frequency component, which in turn led to a change in the sympathetic-vagal balance

Background Few studies perform follow ups on patent ductus arteriosus (PDA) patients who undergo transcatheter closure. In addition to side effects from the procedure, it is important to evaluate changes in left ventricular function (LVF) parameters and nutritional status. Objective To compare LVF and nutritional status before and during the one-year period post-transcatheter PDA closure, and evaluate potential associated factors in post-closure PDA transcatheter patients. Methods This retrospective cohort study was done in a single center in patients diagnosed with PDA who had undergone transcatheter closure. Data were obtained from subjects’ medical records. The relationship between the post-closure PDA time span and LVF parameters [ejection fraction (EF) and fractional shortening (FS)] was analyzed by Friedman and repeated ANOVA tests; the post-closure PDA time period and nutritional status was analyzed by Friedman test. The time periods analyzed were 1, 3, 6, and 12 months post-closure. Factors potentially associated with LVF 12 months post-closure were analyzed by linear regression. Results A total of 30 patients who had undergone transcatheter PDA closure were included. The body weight mean of at the time of transcatheter PDA closure was 13.1 kg. We found a significant relationship between time period after PDA closure and nutritional status, before and 1, 3, 6, and at 12 months post-closure. In a comparison of pre-closure to 12 months post-closure, subjects’ mean EF (66.6 vs. 70.9%, respectively; P<0.001) and FS (34.4 vs. 37.8%, respectively; P<0.001) were significantly higher. In addition, significantly more patients had normal nutritional status 12 months post-closure than before closure. Age was not related to LVF parameters (EF: r=0.212; P=0.260; FS: r=0.137; P=0.471). Conclusion Both LVF and nutritional status significantly improve gradually over the 12 months post-closure compared to pre-closure. PDA size is not significantly associated with improved LVF parameters and nutritional status.
