Discussion Overview

The discussion centers around the claim that women ski jumpers are at a disadvantage due to their mass compared to male jumpers. Participants explore the implications of body weight, center of mass, and skill level in the context of ski jumping, particularly in relation to Olympic competition.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • Some participants challenge the assertion that women are at a disadvantage due to "less mass," suggesting that a lower center of mass could actually provide an advantage in ski jumping.
  • Others reference a New York Times article indicating that lighter jumpers can achieve greater distances, raising questions about the relationship between weight and performance.
  • One participant notes that the starting bar position for women may be adjusted to align their landing distances with those of men, indicating a potential bias in competition structure.
  • Another participant argues that the differences in performance may not solely be due to anatomical differences but rather the proportion of male to female athletes in the sport.
  • There is mention of the prevalence of anorexia among male ski jumpers, suggesting that less mass is generally viewed as advantageous in the sport.
  • A participant points out that a female jumper holds the record for the longest jump, which raises questions about the validity of the disadvantage claim.
  • Some participants express uncertainty about the implications of starting positions and record attempts, indicating that these factors may complicate the discussion of gender differences in ski jumping.

Areas of Agreement / Disagreement

Participants express differing views on whether women ski jumpers are at a disadvantage due to mass, with some arguing for advantages related to lower mass and others supporting the idea of skill level as a primary factor. The discussion remains unresolved with multiple competing perspectives.

Contextual Notes

Participants reference various sources and anecdotal evidence, but there are unresolved questions about the impact of anatomical differences, competition rules, and the influence of athlete demographics on performance outcomes.

On last night's Rachel Maddow show, Bill Wolff made the claim that if women are allowed to compete in Olympic ski jumping, the competition must be changed to make it "fair". He said that women are at a disadvantage because of "less mass". He even mentions F=ma. But isn't his assumption totally false?

Here is the 30-second video clip:

From today's NYT: "Body weight became a critical factor. The lighter a jumper was, the farther he could jump. Depending on the size of the hill used in competition, jumpers said, a weight loss of each kilogram, or 2.2 pounds, could result in added distance of two to four meters or 6½ to 13 feet." http://www.nytimes.com/2010/02/12/sports/olympics/12skijump.html
 
I didn't look at your links, and I'm not into sports by any means, but I would think that a woman's lower centre of mass would be an advantage in ski jumping. Jumpers all lean into the airflow to minimize drag, and a woman would maintain more of her mass toward where the skis are than a man who would be inclined to fall forward. Just a semi-educated guess...

edit: Sorry if I implied disinterest by not looking at your links. I've been up for over 30 hours and have had an awful lot of alcohol. I will look at your links when I feel able.
 
As the NY Times article mentioned, the lighter jumpers have an advantage, depending on the rules about ski size versus height, mass, and body mass index. The starting bar position is set based on how far down the hill the competitors are landing. If it's short of the target range, the bar is raised, if the competitors are landing too far, the bar is lowered. Normally this is figured out during practice. During a round, if the jumpers are landing too far down the hill, the bar is lowered, and the round is rerun.

If the women jumpers are using a higher starting bar position, it's simply to get their landings within the same target range as the men, regardless of the reason.
 
So just to confirm: the difference between men and women ski jumpers is solely based on skill level and not anatomical differences as Bill Wolff claimed?
 
"Less mass" is an ADVANTAGE is ski jumping. This is the reason why anorexia is relatively common among male ski jumpers.
So no, the difference is not only due to skill level. Women should -on average- be better than men.
But which gender that is best on average means absolutely nothing when it comes to top level athletes, simply because they are -by definition- outliers in any distribution.

The real difference in sports like these tend to have more to do with the proportion of make-female athletes, if 99% of all competitors are men it is fairly natural that most of the really good athletes are men as well.

It is quite obvious that Mr. Wolff does not know much about ski jumping...
 
Thanks! I found your information extremely informative.
 
That explains why women aren't allowed in the olympic ski jump event.

I was wondering why there was such a strong objection to women in tight outfits in a very TV-friendly action sport.

A female does hold the record — among both men and women — for the longest jump off of the Whistler ski jump.

Yes, but in that record attempt I thought that she started higher up the hill (which would obviously be an advantage). That's what they say in the video.

Women will not be at any disadvantage since they will only be competing with other women.
