[3] She has been selected to compete for Italy in rifle shooting at the 2004 Summer Olympics and has won a career total of three medals, one gold and two silver, in a major international competition, spanning the World Cup series and the European Championships.

[2][4] Sena's sporting debut came as the youngest member of the Italian shooting team (aged 19), when she qualified only for the women's 10 m air rifle at the 2004 Summer Olympics in Athens.

[5] She had registered a minimum qualifying score of 395 from her top finish at the European Junior Championships in Győr, Hungary, to fill out a quota place for the Games, after the Italian Union of Rifle Shooting (UITS) decided to exchange a spot in the air pistol, won by Caterina Padovan at the World Championships in Lahti, Finland, two years earlier, with the air rifle.

[7][8] In 2014, Sena came to prominence from an Olympic feat ten years earlier with her first gold medal victory over the rest of the field in the rifle three positions at the ISSF World Cup meet in Munich, Germany.

[9] The following year, she added a silver to her career tally in rifle shooting at the European Championships (10 m) in Arnhem, Netherlands, with 204.3, losing in a duel to Germany's Selina Gschwandtner by a 2.5-point margin.
