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.

本研究の目的は,バレーボールゲームにおけるサーブ距離とサーブレシーブ成績との関係を検討することにより,フローターサーブの技術指導に関する資料を得ることであった。大学女子バレーボールの試合71セットをビデオ撮影し,再生画像をパソコンに取り込んで分析した。サーブの位置データは2次元DLT法により算出し,サーブ効果は,相手サーブレシーブ成績をサービスエース,チャンスボール,二段攻撃,コンビ攻撃の4段階評価して求めた。サーブ効果有のサーブ回数が多かった打球距離は,17mと21m付近の二ヶ所あった。サーブの打球距離が長くなれば,ボールが臨界速度に達して空中で急激な変化を生じ,サーブレシーブが難しくなる。またジャンプフローターのような,打球方向が水平に近く,助走踏切中に生じた水平方向の運動量を利用した打球速度が速いサーブを用いれば,打球距離が短くてもボールは空中で変化を生じ,サーブ効果があげられると考えられた。

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.

The purpose of this study was to investigate the read blocking techniques against quick attacks with combination attacks in volleyball. 28 occurrences of blocking motions in 4 games (Poland vs Iran, Poland vs Japan, Cuba vs Argentina, Cuba vs Serbia) from the 2011 Men’s World Cup Volleyball were analyzed by the Direct Linear Transformation Method.     The findings were as follows: (1) The number of occurrences of double blocking (Middle blocker with side blocker) was 11 (Right-side blocker 5 times, Left-side blocker 6 times). Most blocks were single blocks by the middle blocker.     The average of the highest finger-tip heights for blocking motions were right-side 2.80m, middle block 2.97m, and leftside 2.84m. (2) In 11 occurrences of when a middle blocker touched the ball, the average of the finger-tip height for the right fingertip was 2.91m (range: 2.76 to 3.04m), and the left finger-tip height was 2.85m (range: 2.70 to 2.99m). In 8 occurrences, the middle blocker took off -0.016 to -0.134 seconds before the quick spiker hit the ball. (3) When the quick spiker took off, the distance from the net to the middle blocker’s position averaged 0.90m (range: 0.38 to 1.91m). On the other hand, when the quick spiker hit the ball, the distance from the net to the middle blocker’s position averaged 0.66m (range: 0.31 to 1.34m). There was a significant difference between the distance at the time the quick spiker took off and the distance at the time the quick spiker hit the ball (p<0.01). Middle blockers took off 0.150 seconds later when their stance was usually wider than 0.6m.

The purpose of this study was to establish the automated 16mm motion analysis system for three dimensional cinematography(DLT method).Nac motion analyser equipped with graf-pen degitizer,and NEC personalcomputer were used for the 16mm film analysis,where the coordinates were automatically transferred into the computer.The position data calculated by DLT method were very accurate.The mean deviations of computed coordinates from the actualcoordinates were 0.011m in the vertical direction(Z),0.019m in the horizontal direction(X)and 0.008m in the horizontal direction(Y).
