Court advantage goes to men when it comes to tennis, according to a new study that says changing court conditions to address differences in men’s and women’s play might make the latter’s tennis matches more competitive.
“Lowering court nets and playing with lighter tennis balls to accommodate physiological differences would help make women’s matches more competitive, with scores closer to the men’s,” says Dr. Mosi Rosenboim, of BGU’s Guilford Glazer Faculty of Business and Management.
Knowing that other sports adapt rules and equipment to better meet the needs of female competitors, the international group of researchers examined the differences between men’s and women’s tournament scores from the 24 top men’s and 23 top women’s singles tournaments of the 2010 season.
“It is important to note that the current disparity is not related to competitive drive. It is usually attributed to differences in strength and speed, particularly when serving,” says Dr. Alex Krumer from the University of St. Gallen in Switzerland. “While a men’s set is typically a duel of ace serves, resulting in back-and-forth game wins, women break more serves, which results in shorter sets.”
The researchers evaluated the competitiveness of a match according to how close the set scores were. Men’s sets were consistently closer (6-4, 7-5), while women’s sets tended to be more lopsided, with scores of 6-2, 6-1.
“The set-level analysis indicates that physical power, not competitiveness, is responsible for the different number of games per set,” says Dr. Offer Moshe Shapir from NYU, Shanghai.
When researchers re-evaluated the 2010 tournaments and controlled for physical characteristics, such as height and body mass index, the gender gap in final scores completely disappeared. Comparing matches of men and women who were as similar as possible in physical stature yielded the same results: no gender differences in the number of games per set.
“It’s a much-debated subject in the tennis world,” say the researchers. “Level of competitiveness is one of the most important factors in the sports industry, where uncertain outcomes generate more interest from fans and higher ticket sales. This argument also contributes to an earnings gap between professional female and male tennis players.”
After analyzing 3,844 men’s sets and 3,034 women’s sets, Rosenboim and his colleagues Krumer and Shapir, found that men’s scores were closer. For instance, when Novak Dojokovic beat Rafael Nadal in the men’s final of the 2012 Australian Open with a score of 5-7, 6-4, 6-2, 6-7, 7-5, the match lasted nearly six hours. The day before, Victoria Azarenka defeated Maria Sharapova 6-3, 6-0 in 1 hour and 22 minutes.
“If no changes are made, playing on the same courts make men’s and women’s tennis a completely different game.”
The study was recently published in Journal of Sports Economics.
