BACKGROUND

The performance in master marathoners has been investigated in flat city marathons but not in mountain marathons. This study examined changes in the sex differences in performance across time in female and male master runners competing in a mountain marathon compared to a flat city marathon.

METHODS

The association between age and performance of finishers in the Jungfrau Marathon, Switzerland, with 1830 meter changes in altitude and a flat city marathon (Lausanne Marathon), Switzerland, were analyzed from 2000 to 2011.

RESULTS

In both events, athletes in the 35-44 years age group showed the highest number of finishers. In the mountain marathon, the number of female master runners aged > 35 years increased in contrast to female finishers aged < 35 years, while the number of male finishers was unchanged in all age groups. In the city marathon, the number of female finishers was unchanged while the number of male finishers in the age groups for 25-34-year-olds and 35-44-year-olds decreased. In female marathoners, performance improved in athletes aged 35-44 and 55-64 years in the city marathon. Male marathoners improved race time in age group 45-54 years in both the city marathon and the mountain marathon. Female master runners reduced the sex difference in performance in the 45-54-year age group in both competitions and in the 35-44-year age group in the mountain marathon. The sex difference in performance decreased in the 35-44-year age group from 19.1% ± 4.7% to 16.6% ± 1.9% in the mountain marathon (r(2) = 0.39, P = 0.03). In age groups 45-54 years, the sex difference decreased from 23.4% ± 1.9% to 15.9% ± 6.1% in the mountain marathon (r(2) = 0.39, P < 0.01) and from 34.7% ± 4.6% to 11.8% ± 6.2% in the city marathon (r(2) = 0.39, P < 0.01).

CONCLUSION

These findings suggest that female master runners aged 35-54 years reduced sex differences in their performance in both mountain and city marathon running.

背景

在城市平路马拉松比赛中已经对马拉松大师运动员的表现进行了研究，但在山地马拉松比赛中尚未进行研究。本研究比较了在瑞士因特拉肯的阿尔卑斯山马拉松比赛（有 1830 米的海拔变化）和瑞士洛桑的城市马拉松比赛中，女性和男性马拉松大师运动员的表现随时间的变化，以探讨性别的差异。

方法

2000 年至 2011 年，分析了瑞士因特拉肯的少女峰马拉松比赛（Jungfrau Marathon）和瑞士洛桑的城市马拉松比赛（Lausanne Marathon）中完成者的年龄与表现之间的关联，其中少女峰马拉松比赛海拔变化 1830 米。

结果

在这两个比赛中，35-44 岁年龄组的运动员完成比赛的人数最多。在山地马拉松比赛中，年龄>35 岁的女性马拉松大师运动员的人数增加，而年龄<35 岁的女性运动员人数则减少，而所有年龄组的男性运动员人数均保持不变。在城市马拉松比赛中，女性运动员的人数保持不变，而 25-34 岁和 35-44 岁年龄组的男性运动员人数减少。在城市马拉松比赛中，35-44 岁和 55-64 岁的女性马拉松运动员的比赛成绩有所提高。男性马拉松运动员在城市马拉松比赛和山地马拉松比赛中，45-54 岁年龄组的比赛用时均有所提高。在这两个比赛中，45-54 岁年龄组的女性马拉松运动员的表现性别差异缩小，在山地马拉松比赛中，35-44 岁年龄组的表现性别差异缩小。在 35-44 岁年龄组，山地马拉松比赛中的表现性别差异从 19.1%±4.7%缩小到 16.6%±1.9%（r(2) = 0.39，P = 0.03）。在 45-54 岁年龄组，山地马拉松比赛中的表现性别差异从 23.4%±1.9%缩小到 15.9%±6.1%（r(2) = 0.39，P < 0.01），从 34.7%±4.6%缩小到 11.8%±6.2%（r(2) = 0.39，P < 0.01）。
