Team USA forward Meghan Duggan has said that she feels "strong" since returning from a long-term injury last February.
The 26-year-old, who was sidelined for 13 months after suffering a concussion in 2011, helped her country to win the IIHF Women's World Championship in April 2013.
"There were times that were really bad where I didn't know how it would end up for me, so I definitely feel lucky," she told Cosmopolitan.
"I think back [to] when I was struggling really bad. I was thinking of the pros and cons of getting back in and actually taking another hit.
"But since I've been back and I feel strong and I haven't had any problems, I don't feel any hesitation."
USA will take on Finland in Group A at the 2014 Winter Olympics in Sochi on Saturday.
