【背景】αアクチニン3遺伝子(ACTN3)のR577Xやアンジオテンシン変換酵素遺伝子(ACE)のI/D多型は運動能力に関連する。サッカー選手において、瞬発的および持久的な能力はポジションごとに異なるが、遺伝子多型とポジションの関連は不明である。【目的】サッカー選手におけるACTN3 R577XおよびACE I/Dとポジションの関連について検討した。【方法】対象者は、日本のJリーグ、なでしこリーグおよび大学トップレベルチームに所属するフォワード(FW)、ミッドフィルダー(MF)およびディフェンダー(DF)とした(男子:159名、女子:75名)。唾液からDNAを抽出し、TaqMan法によりACTN3 R577X(rs1815739)およびACE I/D(rs4340)の遺伝子型を分析した。【結果】男子選手においてのみ、ACTN3多型の頻度はポジションごとに有意に異なり(P<0.05、カイ二乗検定)、FW>MF>DFの順にRR型が多く、XX型が少なかった。一方、ACE多型は、男女に関係なくポジションとの関連は認められなかった。【結論】男子サッカー選手において、ACTN3 R577X多型はポジション特性に関連する可能性が示された。

This study investigated the occurrence frequency of accelerations (Acc), decelerations (Dec), and changes of directions (CoD) during the actual handball game and their frequency under high intensity events (HIE) circumstances, using inertial measurement units (IMU).     Participants were female handball players in Japan. 10 players (Age: 24.7±2.3 years old, height: 167.0±8.1 cm, body weight: 65.2±6.1 kg) belong to womenʼs division of Japan Handball League (upper group), 10 top-level university players (Age: 20.6±0.8 years old, height: 165.1±5.9 cm, body weight: 61.0±5.6 kg) from the division 1 of Japanese university handball league (middle group), and 8 university players (age: 20.0±0.8 years old, height: 157.9±5.8 cm, body weight: 54.3±5.5 kg) from a team belong to division 2 of the league (lower group).     As a result, the upper group displayed the highest occurrence frequency in all items, the middle group was second highest, and lower group was the lowest. The result indicates that in competition sites, it is important to implement specializing training based on the understanding of the characteristics of handball as a sport and on the scientific knowledge that we could acquire from the actual games.

This study sought to clarify the impact of game format differences on goalkeeper play through a comparative examination of goalkeeper play in games of 8-a-side soccer in Japan and 7-a-side soccer in Catalonia, Spain, two formats used respectively in each region in competitions for players aged 12 years and under. At the same time, it offers a discussion of future approaches to goalkeeper coaching.     This led to clarification of the following:     1) Given that goalkeepers in both countries take the offensive more frequently in game formats with fewer players, such formats appear to be effective for promoting offensive plays by goalkeepers.     2) When the goalkeeper is in possession of the ball, whereas Japanese players have a strong tendency to choose long kicks such as side volleys, Spanish players have a strong tendency to elect to throw the ball to attempt a more reliable relay.     3) Spanish goalkeepers have a strong tendency to be involved in build-up play with passes and support.     4) On goal kicks, whereas Japanese players have a strong tendency to choose long kicks, Spanish goalkeepers have a strong tendency to make short passes to teammates who are in a position to advance the ball.     5) In terms of goalkeeper defense, whereas Japanese players stop fewer shots and make more plays to cover the space behind the defense line, Spanish players stop more shots and make fewer plays to cover the space behind the defense line.
