Dynamic Postural Stability

The production of manifold and rapidly varying movements in team sports requires maintaining an erect posture. This paper aimed to study dynamic postural stability in athletes engaged in team sports. Among the participants were high-level basketball players (n = 15), rugby players (n = 15) and football players (n = 12), as well as 30 young people not professionally involved in sports, all aged 18–21 years. Postural stability was evaluated using stability analyser Stabilan-01 (OKB Ritm, Taganrog). We utilized the Evolventa test, which simulates the real situation of tracking movements in the games, allowing us to quickly assess not only the quality of the athlete’s tracking movement, but also the reserves of maintaining the stability of erect posture. Classical and vector stabilographic characteristics of upright posture stability were analysed. To assess the quality of tracking, special game indicators were used. Athletes demonstrated a significant superiority in the accuracy of performing motor tasks and at the same time in maintaining postural stability over young men not playing sports (p ≤ 0.05). Noteworthy, basketball players had the highest tracking accuracy in the frontal and, especially, in the sagittal plane (p ≤ 0.05). Moreover, basketball players kept their balance much better, surpassing rugby players and, above all, football players in most indicators in both planes (p ≤ 0.05). Thus, the effectiveness, accuracy and speed of completing tasks, as well as fewer errors in high-level athletes were combined with an automated ability, due to the stereotype formed over many years of training, to confidently maintain an upright position even in the most difficult game situations. However, when analysing postural stability, one must take into account the specifics of the sports under study, where a wide variety of ball-handling techniques is combined with competitive activity of the hands or feet.

Research background and hypothesis. Replete schedule of competitions and intense training are features of contemporary team sports. Athletes, especially the most involved ones, may not have enough time to recover. As a consequence, aggregated fatigue can manifest in some undesirable form and affect athlete’s performance and health.Research aim. The aim of this study was to evaluate the changes in heart rate recovery (HRR) and investigate possible relations with sport-specifi c measures of effi cacy in professional basketball players during competition season.Research methods. Eight male high-level basketball players (mean ± SD, body mass, 97.3 ± 11.33 kg; height 2.02 ± 0.067 m, and age 23 ± 3.12 years) were investigated. The same basketball specifi c exercise was replicated several times from September till April during the practice sessions in order to assess the personal trends of HRR. Heart rate monitoring was performed using POLAR TEAM SYSTEM. Investigated athletes were ranked retrospectively according to the total amount of minutes played and the coeffi cients of effi cacy. Research results. There were signifi cant differences in the trends of HRR between the investigated players. The most effective players showed decreasing trends of HRR in all cases of ranking.Discussion and conclusions. Research fi ndings have shown that the quality of heart rate recovery differs between basketball players of the same team and could be associated with sport-specifi c effi cacy and competition playing time.Keywords: adaptation, autonomic control, monitoring training.

Postural Analysis

Background:The adolescent players federated to basketball have a high-level of endurance demand, often overloading the biological tissues and causing biomechanical compensations. Due to the immaturity of their musculoskeletal structures those consequences may influence the growing process and lead to the development of various postural patterns. We aimed to evaluate the postural alignment of the trunk in players.Methods:Participants, 74 healthy adolescents: 36 basketball players (BG) and 38 adolescents in control group (CG). First, adolescents were marked with spheres over specific anatomical landmarks. Postural photographs were taken in the sagittal and frontal planes, and analyzed using the free internet Postural Analysis Software to obtain quantitative measures of the head, shoulders, and trunk.Results:ANCOVA has revealed significant group effects: players demonstrated greater lateral spinal inclination (P < .008). In the right sagittal plane, the BG had lower angular values of forward head position (P < .02), pelvic ante version (P < .02), vertical alignment of the trunk (P < .02), and thoracic kyphosis (P < .005). The covariate analysis has indicated that age influences the alignments of both the shoulders and the left scapula; and height influences the scapular alignment.Conclusions:This study has demonstrated that basketball training within federations influences the musculoskeletal system of adolescents and reflects a process of postural adaptations.

Research Analysis

The essence of effective training in a sports game is the use of means and forms of teaching in the organisation of a game, which most faithfully reflect the environment of the player's actual activity in natural conditions. Thus, there is a need to accurately identify the conditions of competition in a sports game. One of the types of such activities is observation, which being an elementary method of cognition, based on deliberate, targeted and intended as well as systematic perception of the studied subject, process or phenomenon. Research objective and questions The aim of the work is to assess the level of absolutely dependent cooperation (synergy) during a team sports game in changing game situations, in achieving the highest offensive objective, i.e. scoring a goal. - Is the effectiveness of achieving the highest objective of the game in offensive actions (i.e. scoring a goal) dependent on the level of player synergy? - Is the size of the conflict in the sports objective of the game dependent on creative player involvement? Material and test method - In the work, detailed observation was carried out with regard to players' actions in achieving the highest objective of the game, i.e. scoring a goal. The observation concerned analysis of 134 goals scored in 61 UEFA Champions League and European League football matches in 2009-2020. - In this study, the method of observation was used, with the possibility of repeatedly observing events being the subject of research. - In the research analysis, the use of film material of recorded games on a DVD was taken into account, where the observed effects were applied to an observation sheet. - The situations in which goals were scored and the research material comprised teams that competed in a given match. - The observation of scoring goals took the type of situation and level of interaction between players into account. Results Analysis of the obtained results can be inferred: 1. In achieving the highest objective of offensive actions, a high level of synergy prevails, requiring anticipation of events. 2. The high level of synergistic activities increases with the difficulty of situational tasks. 3. Due to the multi-faceted nature of team games, the player's training process should also affect his/her mental sphere.

The purpose of this study was to determine the accuracy of smartphone’s gyroscope for dynamic postural stability among young healthy adults. The research included convenience sample of 85 healthy adults—37 women (mean age 22.1±1.6, body height 167.2±7.0) and 48 men (mean age 22.4±1.7, body height 176.1±13.8). In order to assess the accuracy of stabilometric measurement recorded by mobile phone, the raw data obtained at the same time by Sigma Balance Platform and Smartphone (SP) were correlated. Two thirty-second trials with one-minute interval break were performed (first in the frontal plane and second in the sagittal plane). A total of 170 measurements of postural stability were recorded (85 in frontal and 85 in the sagittal plane). The following parameters were included: the path of the stabilogram (in the case of SP, angular path) and the variation of the swing (standard deviation of the horizontal deflection of the platform). The results have shown strong and significant relationship between body sway variability measured by Sigma platform and smartphone in frontal (r=0.997) and sagittal (r=0.990) plane. For the geometric center of the platform and angular path distances, the correlation coefficient was also statistically significant and high, considering both lateral (r=0.999) and anterior-posterior sway (r=0.981). Our research shows that smartphones with gyroscope have potential for accurate assessment of postural balance, as an alternative for expensive and specialized equipment.

Background/Aim. In modern training technology, assessment of aerobic bioenergetic potential in athletes is commonly performed by standard laboratory procedures to determine basic or specific functional abilities for specific sport activity or discipline. The aim of study was to assess the aerobic bioenergetic potential of athletes participating in basketball, football and handball. Methods. The study included 87 athletes (29 basketball players, 29 football players, and 29 handball players) aged 21-24. Evaluation of the aerobic bioenergetic potential of athletes participating in basketball, football and handball was performed followed by both univariate (ANOVA) and multivariate (MANOVA) statistical methods to determine differences among the athletes in relative (VO2 mL/kg/min) and absolute oxygen consumption (VO2 L/min). Results. Statistically significant differences between absolute and relative oxygen consumption were found in basketball players (Mb), football players (Mf), and handball players (Mh) (MANOVA, p = 0.00). ANOVA also revealed significant differences in relative oxygen consumption (VO2 mL/kg/min) (p = 0.00). The football players (55.32 mL/kg/min) had the highest relative oxygen consumption, followed by the handball players (51.84 mL/kg/min) and basketball players (47.00 mL/kg/min). The highest absolute oxygen consumption was recorded in the basketball players (4.47 L/min), followed by the handball players (4.40 L/min) and footballers (4.16 L/min). Conclusion. Statistically significant differences in the aerobic bioenergetic potential, expressed by the relative oxygen consumption were found among atletes participating in different team sports. It can be assumed that the player from the sports in which it is necessary to cross greater distance in total during the match have a greater need for aerobic capacity.

It can also, according to the individual needs of different players, promote their physical and mental health development and improve the enthusiasm of basketball training, so as to improve the level of basketball technology. Immersive feeling and interest of human-computer interaction are the essential characteristics of virtual reality. The real conception of space-time environment, that is, the process of enlightening thinking and obtaining basketball technology simulation information, is the ultimate goal of virtual reality. In this experiment, five high-level basketball players in our city were selected and numbered from no. 1 to no. 5. Before the experiment, it is necessary to make the players warm up fully before the experiment and then test the forward turning technical movements of basketball. The test variables are based on different angles and distances. After that, standardized selection of basketball technical statistical indicators includes shooting hit rate, two-point hit rate, three-point hit rate, and free throw hit rate. According to the results of the experiment, it took the most time for the curve technique to lower the buffer stage, and it took up 29% of the total time of the entire precursor shot and turned back and the aerial shot stage is 23% and 22%, respectively. There is 20% time in the takeoff phase and 6% time in the brake phase. It has a great influence on the results of the game.

ObjectivesTo determine (1) the prevalence of ankle osteoarthritis (OA) among former professional football and rugby players, (2) assess the association between ankle injuries or ankle surgeries with ankle OA, and (3) compare the mental and physical quality of life (QoL) between former professional football and rugby players with and without OA.MethodsWe conducted a questionnaire-based observational study with a cross-sectional design. Former professional football and rugby players were recruited by the Football Players Worldwide and the International Rugby Players. Information concerning ankle OA, sustained ankle injuries and ankle surgeries was gathered (medical record or most recent medical professional). Health-related QoL was assessed using the Patient-Reported Outcomes Measurement Information System (PROMIS) physical and mental health scores.ResultsOverall, 553 former professional football (n=401) and rugby (n=152) players were enrolled in the study (response rate of 56%). Ankle OA prevalence among former professional football and rugby players was 9.2% and 4.6%, respectively. Football players were more likely to suffer from ankle OA following every ankle injury and/or surgery. Football and rugby players with ankle OA had similar PROMIS physical and mental health scores to the norm for the general population.ConclusionFormer professional football and rugby players had higher ankle OA prevalence than the general population (3.4%). Football players are more likely to suffer from ankle OA following every ankle injury and/or surgery. No clinically relevant difference was seen for physical or mental health-related QoL among football and rugby players. Preventive measures for ankle injuries are recommended.
