本研究の目的は,2006年バレーボール男子世界選手権の撮影ビデオを自作のプログラムにより解析し,世界トップレベルの男子チームが使用している戦術プレーを明らかにして今後の指導資料を得ることであった。サーブレシーブは,全ローテーションを通じて,リベロと後衛レフトと前衛レフトの3選手が横一列の隊形を敷いてレシーブしている。ブラジルは,サーブレシーブ返球がアタックライン上からでもコンビネーション攻撃を仕掛けてくる。コンビネーション攻撃は,セッターが前衛でも後衛でもポジションに関係なく,クイック,パイプ攻撃,両サイドの平行トスの4人攻撃を行う。ブラジルのコンビ攻撃のトス最高値は,従来報告されている値よりもおよそボール2個半(約50cm)低く,攻撃時間がスピードアップしている。アタックレシーブは,クイックとパイプ攻撃に対しては後衛の3選手が扇形に隊形を敷いてレシーブし,サイド攻撃に対してはクロス方向の打球に備えた隊形でレシーブしている。トスが高く上げられた時は,前衛の3選手がブロックに跳ぶ。これらの戦術プレーの分析データと同一競技場面の動画をスクリーン上に表示して選手に観察させることは,相手対応の準備など効果的な指導方法の一つとして役立つと考えられる。The purpose of this study was to clarify the playing system used by the international-class men's volleyball teams that participated in 2006 Men's World Championships held in Hiroshima, and to provide the scouting information with coaching volleyball. Through all rotation, a libero player and backward left player and forward left player stand in a row and receive a serve. Team Brazil challenges combination, even if serve receive ball was on the attack line. Whether a setter is forward player or not, they attack with four players, one plays quick, the other plays pipe attack, others attack parallel sets from both side. The height of sets used Brazilian combination attack is two and a half balls lower than ever known, so their attack speed rose. About attack receive for quick and pipe attacks, three players receive with a fan-shaped formation. For side attacks, they prepare for the ball from cross attacks. With high sets, three forward players block a ball. It's useful for players to observe moving image which is the same as the scene used as a data to analyze their tactics. It's one of the effective way of coaching to prepare for dealing with an opponent.

With the objective of clarifying which performance indices are correlated with the outcome of the game for attacks following serve-reception in international men's volleyball tournaments, this study analyzed the 2015 Volleyball Men's World Cup. The results obtained are as follows. (1) Considering all attacks when in-system, and using each team's percentage of winning the set as the variable, very strong positive correlations were confirmed for the attack efficiency (r =0.948, p <.001) and kill attack percentage (r =0.902, p <.001). (2) Considering quick attacks when in-system, and using each team's percentage of winning the set as the variable, a very strong positive correlation was confirmed for the attack efficiency (r =0.787, p <.01) and kill attack percentage (r =0.711, p <.01), and a relatively strong negative correlation was confirmed for the percentage of losing points from an attack (r =-0.582, p <.05). (3) Considering pipe attacks when in-system, and using each team's percentage of winning the set as the variable, very strong positive correlations were confirmed for the kill attack percentage (r =0.876, p <.001) and attack efficiency (r =0.784, p <.01), and a relatively strong positive correlation was confirmed for the attack attempt percentage (r =0.629, p <.05). (4) Considering front side attacks when out-of-system, and using each team's percentage of winning the set as the variable, a relatively strong negative correlation was confirmed for the blocked attack percentage (r =-0.606, p <.05).From the above, it became clear that in terms of attacks following serve-reception at the 2015 Volleyball Men's World Cup, in-system attacks are correlated with the outcome of the game, especially with correlations found in the potency and accuracy of quick attacks, and the potency and frequency of pipe attacks. In addition, it was confirmed that for out-of-system front side attacks, the points lost due to being blocked by the opponent had a correlation with the outcome of the game.

Little attention has been paid to the distinguishing competitive characteristics of volleyball, despite the importance of this issue. This study treated these characteristics as lthe special characteristics that distinguish volleyball from other sports.z The purpose of this study was to clarify the distinguishing competitive characteristics of volleyball. The definition of volleyball, which describes these characteristics, is as follows: lVolleyball is a sport played by two teams on a playing court divided by a net, within the limit of three hits in the team allowed before sending the ball to the opponent's court, they repeatedly attack by aiming to have the ball contact the ground on the opponent's court, repeatedly defend against the same attacks made by the opposing team, and compete for a point obtained by winning a rally.z This study concluded that the symbolic moving form emblematic of volleyball is the lspike,z a typical scoring skill. The reason was the attack-point by spikes results in the highest number of points achieved in volleyball games.

Many studies have been conducted to explore the factors that determine a performance of the individual player or team in the volleyball, and they have found that some specific motions for the individual player or team have an influence on their performance. However, there is a shortage of empirical analysis on the determinants of match results, it has not been clarified yet. This study applies an econometric method and empirically examines the determinants of match results using a sample of Men's Matches in Kansai University Volleyball Federation from 2014 to 2017. The result shows that the average number of the block is the most important factor to win the match.

The purpose of this study was to analyze the characteristics of the setting technique in combination attacks focusing on the trajectory of the ball was set and the arm of the setting motion. The setting motion of the setters that were playing in world − class competition was analyzed. The general tendency was extracted from the analyzed data, and was explained biomechanically. The trajectories of the balls was set were close. And the characteristics of the setting technique in combination attacks are on the following two points. 1)The arm angle is approximately 137 degree from touching to release the ball. 2)The timing formed the setting posture is approximately 0.233 second before touching the ball(approximately the take − off). It is considered that their two motions are useful not to give blockers the clue of the set direction before releasing the ball. After releasing the ball,the close trajectory of the ball suggests that it is difficult for blockers to judge the position attacked.

This study was designed to develop a device (DSH) to measure the maximum spike height (Hs-max) in volleyball and examine its measurement methods. DSH measures the height of a ball, which is suspended and can be moved between 200 and 380 cm from the ground,when it is hit by a player. We selected thirty male university volleyball spikers, and measured the height of the tip of the middle finger with their arm stretched overhead( Hf) and the maximum vertical jump height( Hmax). Then, we asked them to spike a tossed ball, and measured the height( Hs) and speed of the ball when it was hit, using the 3D direct liner transformation( DLT) method. After having spiked a ball at many different levels, players evaluated the height( SAh) and speed( SAv) of the ball in each spike on a ten-score scale. We defined the height of the ball when [SAh + SAv] is maximum as “Hs-max” There were correlations between the ball height and SAh, and the ball speed measured by DSH and SAv. Since there was also a correlation between [SAh + SAv] and SAh or SAv, Hs-max proved to be valid. We selected twenty female university students, and measured Hs-max twice in two days using DSH. The reliability coefficient for the measurements was as high as 0.913. We divided the players into two groups: Group HS (n=15), players who spiked the ball at a height of 285.5 cm or more; and Group LS( n=15), players who spiked at 285 cm or less. Hs-max was significantly larger( p<0.05) and “Hs-max - Hs” was significantly smaller( p<0.01) in Group HS, compared to Group LS. The players in Group HS not only spiked the ball at higher points,but they were also good at controlling the timing of jump in order to spike at their maximum jump than those in Group LS. We concluded that the newly developed device, DSH, can measure the Hs-max values with excellent reliability and that the the Hs-max would provide valuable information for both players and coaches.

Soft volleyball was developed as new sporting games that anyone can easily enjoy according to the age, sex, physical fitness, and skill level. The purpose of this study was to categorize soft volleyball enthusiasts and capture their characteristics to obtain basic data for future popularization and development. Focusing on the player`s goal sacrificed, we categorized it using factor analysis, cluster analysis and confirmed whether there was a difference by analysis of variance. The results showed that soft volleyball enthusiasts were engaged in competition and life satisfaction as their primary objective. It was also possible to classify the enthusiasts into three types. Type A was primarily sacrificed competitiveness. Type B worked with a variety purpose thinking, such as self-health, leisure, and competitiveness. Type C aimed at self-health and competitiveness, but did not have purpose about leisure. Type B was the most recognizable effect by playing soft volleyball. It became clear that more effects can be enjoyed by performing for various purposes such as self-health, leisure, and competitiveness. It is also effective to approach people who have no experience of volleyball and increase the category of competition.
