Volleyball and Talent Identification

The purpose of this study was to analyse netball and volleyball players for differences in physical performance parameters among female university players. Materials and Methods: Twenty-eight female participants (14 netball + 14 volleyball players) participated in this study voluntarily. Any player with lower extremity musculoskeletal injury or a record since the last three months was excluded from the study. The average age of players was 19.54±0.69 years, body weight 52.99±10.51 kg., height 156.71±5.34 cm., and body mass index 21.57±4.09. Anthropometrical characteristics were measured with the help of a bioelectrical impedance analyser, while physical performance parameters (Muscular endurance, lower extremity power, dynamic stability, agility, speed) were determined by the numerous functional tests. Results: No statistically significant differences were found in physical performance parameters except agility (p=.041) and speed (p=.015) variables between netball and volleyball university female students. A significant positive relationship was also found in some of the physical performance parameters irrespective of the sports. Conclusion: The study's findings show that physical performance parameters do not differ significantly in female netball and volleyball players. Team coaches and physiologists must consider functional test outcomes while preparing players for competition. The individual training program should also be established on test outcomes, which is more likely to improve performance.

The purpose of this study was to investigate body composition, some anthropometric characteristics and somatometric components of under elite female volleyball players in relation to their playing positions. This study was performed on 101 volunteer athletes. Somatotype characteristics of athletes were evaluated by Heath-Carter Formula, body fat percentage was calculated by Sloan and Weir Formula. Significant statistical differences were found between playing position and endomorphy scores. Body fat percentage values of setters different from centers’ (p<0,05). In conclusion, it was found that some physical and somatometric components were different among athletes of different playing position. It is thought that physical and antropometric examination before sports participation or direction to playing position are beneficial for related persons to take optimum performance from athletes.

Purpose: The first purpose of the study was to find out correlation between Independent Variables (selected Anthropometric
Parameters) and Dependent Variable (Volleyball Playing Ability). The second purpose of the research was to study the joint contribution
of Independent Variables in estimating Dependent Variable and the third purpose was to establish regression equation for predicting
Dependent Variable on the basis of Independent Variables. Selected Variables were Height, Weight, Arm Length, Upper Arm
Circumference, Leg Length, Thigh Circumference (Independent Variables). Methodology: Total of 48 male Inter-university level
Volleyball players were selected from different colleges of R.M.L.A.U Faizabad during inter collegiate tournament. Age of the subjects
was ranging between 18 to 25 years. Selected Variables were Height, Weight, Arm Length, Upper Arm Circumference, Leg Length,
Thigh Circumference (Independent Variables). Volleyball Performance was considered as Dependant Variable. The selected physical
fitness variables were measured by different tests and performance was measured through subjective rating with the help of three
experts of volleyball game, at the time of match. To find out correlation between Independent Variables (Height, Weight, Arm Length,
Upper Arm Circumference, Leg Length and Thigh Circumference) and Dependent Variable (Volleyball Performance), Product Moment
Method of correlation was used. To study the joint contribution of Independent Variables in estimating Dependent Variable, Multiple
correlation method was used. Regression equation was established for predicting Dependent Variable on the basis of Independent
Variables. Findings: There exists a significant relationship between Volleyball Performance and Weight (r = -.268, p < .05), Height (r =
.638, p <.05), Arm length (r = .492, p < .05) and Thigh Circumference (r = .262, p < .05). There exists an insignificant relationship
between Volleyball Performance and Upper Arm Circumference (r = .107, p > .05) and Leg Length (r = .182, p > .05). Regression
equation (Volleyball Performance = 28.032 - 0.104(Weight) + 0.227 (Height) + 0.057(Arm Length) + 0.064(Thigh Circumference) was
found fructiferous in estimating Volleyball Performance on the basis of selected Anthropometric Variables (Height, Weight, Leg
Length, Thigh Circumference).

Smilios, I., T. Pilianidis, K. Sotiropoulos, M. Anto-nakis, and S.P. Tokmakidis. Short-term effects of selected exercise and load in contrast training on vertical jump performance. J. Strength Cond. Res. 19(1):135–139. 2005.—The present study examined the short-term effects of loaded half squats (HSs) and loaded jump squats (JSs) with low and moderate loads on the squat jump (SJ) and the countermovement jump (CMJ) performance using a contrast training approach. Ten men (mean SD age, 23 1.8 years) performed the HS and JS exercises twice with loads of 30% of 1 repetition maximum (1RM) (HS30% and JS30%, respectively) and 60% of 1RM (HS60% and JS60%, respectively). On each occasion, 3 sets of 5 repetitions with 3 minutes of rest were performed as fast as possible. Vertical jump performance was measured before exercise, 1 minute after each set, and at the fifth and 10th minutes of recovery. The CMJ increased significantly after the first and second set (3.9%; p 0.05) compared with preexercise values following the JS30% protocol and 3.3% after the second and third sets of the JS60% protocol. Following the HS60% protocol, CMJ increased after the first and the second sets (3.6%; p 0.05) compared with preex-ercise values, whereas SQ increased only after the first set (4.9%; p 0.05) in this condition. These data show that contrast loading with the use of low and moderate loads can cause a short-term increase in CMJ performance. The applied loads do not seem to present different short-term effects after loaded JSs. When the classic form of dynamic HS exercise is performed, however, at least a moderate load (60% of 1RM) needs to be applied.

The objective of this study is to approach the decision-making process in volley ball through the perceptual learning by simulation. 148 pupils took part voluntarily to this experience. The pupils were divided into two groups. An Experimental Group (EG) which was to follow a program of learning of the technics of the Volley Ball on computer (Images in 3D) before they begin the learning and a Control Group (CG) who performed the classical learning through technical exercises. Tests have been realized after a period of learning on different technics of volleyball. The results showed that the group experimental had significantly improved these results during the decision-making. This study shows the need to use the new technology (simulation) to optimize the mental skills in teaching volleyball.

The purpose of this study is to set forth the changes made in the purposes of rule changes. The document analysis method, one of the qualitative analysis methods based on the collection of data by examining the existing records and documents, has been used in this study. It has been noted upon examining the findings attained as a result of the analysis that the major rule changes made could be mainly grouped under six headings. These may be listed as, " improvement of the playing court and physical conditions " , " protection of player health " , " increasing game continuity by reducing interruptions " , " enhancing spectator pleasure by increasing rally durations " , " increasing TV broadcasts " and " standardization between volleyball and beach volleyball ". In spite of the positive developments, there are players, trainers, spectators and sports commentators who believe that certain changes such as " partial freedom in the net contact and crossing over to opponent's court " however, might increase player injuries although they increase game continuity.

O voleibol é uma modalidade esportiva com 120 anos de existência. Foi criado por William George Morgan (1895) na cidade de Holyoke - Massachusetts (USA). Com o passar do tempo o voleibol sofreu várias modificações que o levaram de esporte menos fatigante, praticado apenas por homens de meia idade, a esporte do século XXI, mania nacional, segundo esporte mais praticado no Brasil, fenômeno de público, mídia e exemplo de sucesso. A formação de reservas esportivas tornou-se uma exigência do desporto de alto rendimento como forma de reabastecer a composição das equipes nacionais. Sendo assim, é necessária a preocupação com os procedimentos metodológicos utilizados na preparação dos jovens, através do controle dos índices obtidos em avaliações das características genéticas, maturacionais, morfológicas, funcionais, motoras e da capacidade técnico-tática dos atletas das categorias de base - índices intermediários. Com a comparação destes índices é possível determinar a predisposição ao sucesso ou ao fracasso na modalidade. Vale lembrar a necessidade de utilização de referenciais que permitam a comparação desses atletas com seus pares, bem como em relação a si mesmo.

The aim of the study was to identify motor structures in elite female volleyball players aged 14-17, and to assess the effect of these motor structures on their technical and situation efficiency. For this purpose, a battery of 12 motor tests as predictor variables, and a set of six technical elements and evaluation of performance quality as criterion variables were applied in a sample of 147 female volleyballers aged 14-15 and a sample of 50 female volleyballers aged [16][17] 14-15 and 16-17, whereby the mechanism of strength regulation had greater effect on the game performance than the mechanism of speed regulation. Regression correlation analysis also revealed the set of 6 techniques evaluated to be a good predictor of situation efficiency in both groups of female volleyballers aged 14-15 and 16-17. The block and spike techniques were found to be the best predictors of game performance quality in the former, and the techniques of spike and block in the latter. Based on the results obtained, a possible model of selection for supreme score achievement in female volleyball is described.
