I think a lot of the growth for the Athletic Apparel, and Food and Sport Drink sectors have to do with increased marketing towards Women. Women, generally, are the ones who spend money buying clothes and food/drinks. In the last decade or so there seems to be an increased interest in getting women more involved in sports, companies catering their athletic apparel, and food and beverage offerings to women. Good examples of that would be Nike Women, NFL 4 Her, and various low calorie sports drinks, like Propel. Women have asserted more influence on the male dominated Sports industry (http://www.sportsnetworker.com/2012/12/13/top-10-inspirational-women-in-sports/), so it’s no wonder companies are seeking to benefit on this influence.
