Although encouragement of hiring women there has not been a dramatic growth of either them in professional coaching. Title IX stimulated women's introduction and participation in sports, a small percentage is involved in coaching. With few women coaching women's sports, they are almost never seen coaching men's sports on the professional or college level.
There are a wide array of reasons the number of male coaches could significantly outnumber female ones. One reason offered is that males play a more dominate role in sports because the role the athlete's dad played in their childhood. Often dads are the more athletically driven one in parenthood, that drives their young child to participate in sport. They grow up coaching them, so when they arrive at the professional level the athlete is used to having the male figure play the coaching role in their life.
Many assume men are just overall better coaches than women. Women do not have the same great stats as some men have, but women have had less opportunity to prove their potential as coaches. Usually males are seen as fiercer, more competitive, and have a greater edge that makes them better coaches. I do not believe this is true. Women can be just as competitive and driven as their male equivalent.
Is it possible that fewer women are interested in becoming coaches and aren't drawn to the sidelines? This I see as a definite possibility. With few women in professional college positions, I could imagine few see this a career option. I can also imagine its hard to hold a professional coaching positions while being wife and mother. The coaching job is very demanding and requires a large time commitment. I believe fewer women are interested in making that sort of commitment. I feel we can do more to bring in women to the coaching world. Although t gender equality has grown significantly with the passage of Title IX there is still a long way to go.
