As a former coach for junior cheerleading, I would say yes. I had many cheerleaders who were forced to join the team by their parents (thus making them less interested in actually participating). I had parents who would stand behind me and critique their daughters, "You aren't loud enough!", "If you don't get it together, you are going to lose it for the team at competition!"  

I noticed the same thing when it came to the young football players. Some who were as young as 5 years old. The parents made it seem as though winning simple youth football games gave their children an opportunity in the NFL. The parents would yell at the coaches for not pushing the kids hard enough. I've seen parents force their kids back on the field after their child had an injury or breathing issues. I've known kids whose parents forced them to prep for games for 2-3 hours before a game actually started. This prep often consisted of plenty of water, rest and stretching however it took kids away from working on homework, school projects or normal down time that children usually have.  

When I was involved in youth sports, it was fun and we were taught to cherish the experience and to work as a team. Now, it is all about being the best, whose kid is better and winning (for the most part).
