Training Contributions at Mini-volleyball Level

Abstract We intend to increase the number and the efficiency of game skills, by temporarily altering the official rules, and imposing certain executions for the beginner level. We assume that: compulsory execution of two certain volleyball skills will reduce the number of errors of the actions in the first part of the volleyball phase, increase the total number of individual and collective executions (tactics) during a match, and increase the number of situations where a dispute advances in late phases. The results confirmed our assumptions and the Romanian Volleyball Federation included our percepts in the official mini-volleyball rules.

Changes in the physical fitness of volleyball players

Objective: Volleyball is one of the most popular team sports in the world. As this is a non-contact sport, it is also regarded as a pleasant and safe form of recreation. However, there are commonly known reports about serious injuries which players who represent the highest level of sport performance suffer from. Attempts have been undertaken to define the scale of changes of health-related physical fitness components of the players participating in the starting season of the extra league of Polish Volleyball League. Method. Using the selected attempts of Eurofit test, health-related fitness features of the 12 players were examined at the beginning and at the end of the starting season in the following scope: flexibility, static arm strength, abdominal strength and endurance. In addition, explosive leg power as the most characteristic part of special volleyball skills was measured as well as the basic values of morphological features. Results. With the exception of flexibility, the test results showed a negative effect of starting season on the level of the physical fitness components examined. Not only did the components relate to performance-related fitness deteriorated, but also the health-related ones did. Thereby, the research results demonstrate negative effects of intensive performance of physical activity which is widely considered as beneficial for health. Conclusions were made about the necessity of selecting the intensity level of exercise which matches one's individual abilities. In case of professional sport, conclusions suggest paying attention to maintaining appropriate configuration of health-related physical components.

Statistical study on bodily communication skills in volleyball to improve teaching methods

Focus of the study is to verify the incidence of performance analysis data of bodily communication in volleyball. The sample was chosen to represent the scores obtained in three technical skills strongly influenced by bodily communication: the second ball goes to the opposite court instead of setting for attacking; the attack as fast as possible in the middle of the net and the off speed hit instead of power spike over the block. The purpose of this study is to measure the amount of the three technical skills points for each set, the total of them, the points awarded to the attack and the total points of each set, and so to read the relations between the different categories of scoring. The method used is the recruitment of the data with the use of video software Data Project by a team of operators made by the team’s official analyst, by the coach and by the single athlete, only for measurements concerning him. The assignment of the data is attributed by the team's official analyst after sharing with the coach and the athlete. The datum recruited must necessarily accepted by the coach, otherwise is not considered. The data recruited were compared with data on total points in the set and with the overall results of the attack, first individually and then together, in order to determine the relationship among points attributable to bodily communication and the final score. The dependency relationship, analyzed through a simple regression model, was statistically significant. The results show as this study can help the coach to train the team for improving the analyzed technical skills in different mode, creating a methodological system training to enhance the performance.

Volleyball players training intensity monitoring through the use of spectral analysis of heart rate variability during a training microcycle

Background: Volleyball players in different specializations are required to meet specific demands in terms of movement behaviour and skills performance. These specific demands need to be individualized according to the training ability level (adaptability to sports training) of particular players, which is mainly dependent on the activity of the autonomic nervous system (ANS). Spectral analysis of heart rate variability (SA HRV) gives us information on cardiac activity regulation, where the activity of ANS participates in a significant way. Longitudinal assessment of SA HRV within a certain part of a training period can help us to observe the dynamics of the ANS activity and adaptability (training ability) changes of an observed player to training. Objective: The goal of the work was to verify the possibility of volleyball players' training load optimalization during a one week training microcycle based on the longitudinal observation of dynamics of SA HRV complex indices. Methods: The SA HRV method was used for the evaluation of autonomic cardiac regulation. The study group consisted of eight volleyball players who took part in 28 training sessions focused on conditioning and volleyball skills development. During the microcycle, there were 7 HRV examinations. Results: The results demonstrated that notable and considerably varied changes in the activity of ANS in players were assessed owing to both training and extra-training stimuli. The results in two players show a high activity of ANS which enables them to increase their training intensity. Four players achieved average values of their ANS activity, which reflects a corresponding training load. In the last two players we found a very low level of their ANS activity and it refers to their reduced adaptability to the training load, which was too high for them. Conclusions: The presented results support the necessity of the individualization of, at least a part of, team training. Such an optimalization and increase of training process efficiency should lead to a sports performance improvement, also in team sports games.

Evaluation of tactical-technical skills development in volleyball teams male infant

The aim of this study was to evaluate the development of technical and tactical skills resulting from the methodological approaches used for the teaching-learning-training process of male infant volleyball players. Thirty athletes and their coaches, responsible for two teams from Santa Catarina (Brazil) experienced in the formation of athletes, participated in the study. The groups analyzed were submitted to pre- and post-tests for the evaluation of technical and tactical skills. The procedures used were the evaluation of technical-tactical actions of the players in the games and systematic observation of typical weeks of technical-tactical training. Descriptive statistics (mean, percentage, frequency and standard deviation) was used applying the Mann-Whitney U test and Wilcoxon test, with the level of significance set at p<0.05. The methodological approaches used by the coaches were similar in terms of notion of refinement and appliance, and differed in terms of notion of progressions. The results indicate that the development of technical-tactical skills of the athletes seems to depend more on the time spent for training of actions than on the concepts and methodologies implemented in the training. The process of teaching-learning-training used by the teams was able to improve the level of technical-tactical skills of the athletes. However, no significant differences in the development of technical-tactical skills of the athletes were observed between the methodological approaches adopted by the coa¬ches during this process. Future studies are necessary to analyze the verbal behavior and specific strategies adopted by the coaches for the development of tactical skills in volleyball.

Gender Bias in the Effect of Dropping Height on Jumping Performance in Volleyball Players

The goal of the present study is to investigate in skilled volleyball players (a) the effect of dropping height on women's and men's performance and (b) the drop jump technique with regard to gender. Nine male and 9 female skilled volleyball players were instructed to jump as high as they could, using a drop jump, from a box of 30 cm or from 2 boxes (60 cm). Kinematic and kinetic data were collected using 6 cameras and a force plate. The human body was summarized by using a 4-segment model (foot, shank, thigh, head-arms-trunk). Males performed higher jumps than females (46.6 +/- 7.5 cm vs. 36 +/- 5.4 cm; p < 0.05). This could be explained by higher mean power (56.9 +/- 26 W/kg vs. 42.4 +/- 19 W/kg; p < 0.05) and shorter eccentric time (-46.3%), both of which allowed a better stretch-shortening cycle. This study shows that women and men have different jump techniques when they drop from a higher position but without increasing the vertical performance. Women increase the values of force and stiffness (respectively +21.4% and +17.9%) without changing the temporal structure of the jump. Men reduce the eccentric time of the jump (41% vs. 31.8%) and keep the force parameters constant. The study findings indicate that it is necessary to find an optimal height for plyometric training for each athlete, allowing enhancement.
