The lowdown on American archer Mackenzie Brown: She knits, line dances, used to be a competitive swimmer -- backstroke was her specialty -- and shoots arrows while listening to country music to hone her concentration.Then theres this: The 21-year-old from Flint, Texas, may just be the archer to interrupt the dominance of South Korea, the nation thats captured seven of the last eight Olympic gold medals in the womens individual event heading into Rio.Brown certainly has the aim to pull off the feat -- the poise, too.If I go in with the right amount of confidence, Im usually going to do really well, said Brown, whos attempting to become the first U.S. woman to win Olympic gold since Luann Ryon in 1976.

From the start, she was talented -- winning tournaments in divisions above her age.I grew up in deep Texas, where all I heard of was bow hunting. I had this image of the movie `Robin Hood: Men in Tights. Thats what I knew about archery, Brown said. Soon, I found out it was so much more. It was something I definitely have a passion for.Typically, she will train to music in order to work on tuning out distractions. When shes not listening to country stars like Garth Brooks or George Strait, shes jamming to Meghan Trainor.Being able to push that (noise) away and focus on what I need to focus on, it becomes a benefit, explained Brown, whose hobby is knitting and makes garments to protect her equipment while traveling. Im just really looking forward to how things turn out.The archery competition starts Aug. 5.
