Cisneros made his first international appearances in 2007. He began his career competing both the hurdles and the
400 metres sprint. After ran a personal best time of 46.05 seconds for the flat race at a local meeting in March, he won the national junior title in the event. He won two titles at the
2007 ALBA Games, running a national junior record of 49.57 seconds to win the 400 m hurdles before going on to help the Cuban
4×400 metres relay team take a second
gold medal. He was chosen for the Cuban squad at the
2007 Pan American Games and managed to reach the semi-finals of the 400 m, although the relay team were disqualified in the heats. He decided to focus solely on the 400 m flat in 2008 and dipped under 46 seconds (45.98) to take the
bronze medal at the
2008 Central American and Caribbean Championships. A team comprising
William Collazo,
Yunier Pérez, Cisneros and
Yeimer López also won the relay
gold medal and their time of 3:02.10 minutes meant the team had achieved the Olympic qualifying time. Cisneros won another gold with the relay team at the
2008 Ibero-American Championships in Athletics and went on to make his Olympic debut at the age of eighteen at the
2008 Beijing Games, where he ran a split of 44.36 seconds in the heats. A personal best of 45.76 seconds for the 400 m opened Cisneros' 2009 season, but it was at this point that he began to focus more on the 400 m hurdling event. He ran a personal best of 49.49 seconds to win the gold at the
2009 ALBA Games and also helped defend Cuba's relay title. At the
Barrientos Memorial he improved his best by almost half a second, running a time of 48.87 seconds to become the second Cuban under 49 seconds after
Yacnier Luis. He was a little short of this form at July's
2009 Central American and Caribbean Championships in Athletics, where he finished in fourth place, but he did win a consecutive relay gold medal for Cuba at the competition. With no major competitions scheduled for 2010, he made his debut on the
Diamond League circuit, coming fifth at the
Doha meeting. He won gold medals at the
2010 Ibero-American Championships in Athletics both the hurdles and relay events. That July in
Havana he improved his 400 m hurdles best by six tenths of a second, breaking the
Cuban record held by Yacnier Luis with a run of 48.29 seconds. Two weeks later, the 20-year-old went even faster with a time of 48.21 seconds. He ended the competition with a second victory in the 4×400 m relay and the time of 2:59.43 minutes set by a team of
Noel Ruíz,
Yoandri Betanzos, Cisneros and Collazo was the fastest by a Cuban quartet since the
1992 Barcelona Olympics, where the country won Olympic silver. At the 2012 Olympics, he competed in both the 400 m hurdles and the 4 × 400 m relay team. He finished 4th in the 400 m hurdles at the
2013 World Championships. ==Personal bests==
