Introduction In the last years, the Swedish world class Team Ahmann / Hellvig (AH) reinvented beach volleyball by introducing the "Swedish Jumpset". They create two options on the second ball contact (Second Ball Option (SBO)) by attacking the second ball or fake attack and fast jumpset. This causes temporal pressure on the opponent block player since attacking position stays unclear quite long. This study focusses on seven research questions including i) how often and in which situations do AH create SBO, ii) which factors influence the decision second ball attack vs. jumpset, iii) is setting quality reduced in SBO?, iv) is block quality reduced in SBO, v) how do AH attack in SBO, vi) how effective is attack in SBO, vii) do opponents adapt to this playing style? Methods In order to answers these research question, we analyzed 34 matches on world level 2021-2023 (19 won, 15 lost). The sample includes pairs of matches against same team (early match, second match ~ one year later). Notational analysis based on video recordings and uses a compressive observational system including performance variables associated with SBO such as position of contact points, quality of reception, setting, block and attack as well as direction of the ball and temporal variables. Results Results show a surprisingly high ration of situations with SBO (50,5%). Against power server on Ahman SBO rate is decreased (50.7% vs. 59.3%) Both players chose attacking option more often (~66%). There are nor hints towards setting problems when using jumpset. Block quality against attack on contact 2 is quite low (only 35% in time). On optimal setting position kill rate is increased by ~12% compared to non SBO situations. Opponents were less successful in blocking against A/H in the second match. Discussion & Conlusion AH used the "Swedish Jumpset" very often. By doing this, they reduced block quality, without introducing inaccurate setting. This leads to a higher kill rate compared to non SBO situations. Opponents were no able to create countermeasures in the second match. Attacking success suggest that AH, were only able to establish themselves in the world top3 teams, because the take use of this tactical/technical mean.
