On this week’s episode of AfricanVoices, CNN International explores the growing interest in contact sports in Africa by meeting athletes from Nigeria, South Africa and Senegal.

Growing up in Aiochi, Nigeria, UFC Fighter Kamaru Usman remembers how the struggles he faced as a child helped prepare him for the hard work it takes to be a champion.

He tells CNN: “I remember the streets, I remember having to walk what seemed like miles to fetch water from the wells with my grandmother. I recall the hard work that my family went through just to continue to live the lifestyle that we were living, which wasn’t by any means a great lifestyle.”

For Usman, a spiritual belief has helped him maintain his conviction, he explains: “I believe in fate. I believe in karma. For me, it’s whatever God has in store for me. If God said that this was how you get that title shot, I don’t want to be the guy to say, “Oh, well, I wasn’t ready. I wasn’t prepared.” I wanted to make sure that I was prepared because I don’t know God’s plan. Maybe God wanted me to get it a certain other way, but I’m gonna do everything in my power to make sure thatI’m a champion.”

African Voices meets Usman in Dallas, Texas as he trains to become a champion. He tells CNN about the work he does to remain competitive: “I had to diet, I had to go through the whole training camp. I had to put my body through that stress and just the rigorous training that you go through. I went through all of it and then I had to step on the scale and make the weight.”

Usman not only trains to be successful but also helps encourage other athletes in Africa. He explains: “When it’s training time, we push each other and do anything to help each other and when it’s fight time we’re always there for each other. If I see you doing something that’s wrong or I see something that can help you change your game I’m going to always give those tips especially with another of my African brothers. We eat the same food, we come from the same walks of life, so it’s a different bond.”

On his future in the sport, Usman tells CNN about his aspirations: “In a couple years from now in this sport, I will be the champion.

“I would have defended the belt a few times. Secured or solidified my place in the hall of fame as one of the greatest to ever do this, and all the while inspiring not just Africans, but inspiring kids across the world that have a similar story to myself.”

Another athlete African Voices also meets is Women’s Flyweight and Bantamweight champion Amanda “Mad Dog” Lino from South Africa. She explains to CNN what encouraged her to be the champion she is today: “Something that really changed my life would have to be losing my f ather.

“You know that really brought focus and dedication into my life because going through a struggle and losing someone that you love would make you focus on what you need to on a day to day basis. I think that it’s most shaped me and made me realize that life wasn’t all about having fun and not focusing.”

Lino explains how criticism she faced encouraged her to work harder: “Everyone kept telling me girls are never going to be successful in MMA, it’s a man’s sport or it’s a boy’s sport… So being the competitive person or the one to push boundaries, I was like well no, I’m going to make sure that female athletes get into MMA and make a difference.”

The final athlete African Voices meets is Olympic Taekwondo athlete Balla Dieye from Senegal. He tells CNN about the challenges he has faced in the sport: “Before, when you start Taekwondo in Senegal it was very difficult because it’s not our culture. When you show some people, I make Taekwondo, they say, “What’s Taekwondo?” [they] thinks its karate. Because [they] see movies from Jackie Chan and Bruce Lee. But now,it’s different now. We know this is karate, this is Taekwondo.”

Dieya tells the programme about his experience at one of the biggest sporting competitions in the world: “When I goto Olympics, I [was] training for six hours a day. And four hours for me is physical preparation and two hours is only from sparring…. We do all exercise here.  If you have your body very strong then you’re going to fight easy.You need flexibility, you need speed, and you need those strong, power for scoring.”

On his future hopes Dieye tells CNN: “I need Olympic medals now, this is dream for my taekwondo. In Senegal everybody waiting this medal. All sport. Everybody waiting the next medal for taekwondo, the next medal in Senegal. Why I [am] pushing a lot this new generation, I give my motivation, I give my time, I give my energy to make focus for this medal… I think the dream is coming soon.”
