Demographic and performance data from 197,825 athletes competing in "Engadin Ski Marathon" between 1998 and 2016 were analysed. When all finishers per age group were considered, there was no gender difference in time (2:59:00 in women versus 2:59:09 h:min:s in men; P = 0.914, η < 0.001) and the main effect of age group on time was trivial (P < 0.001, η = 0.007). When the top 10 finishers per age group were considered, men were faster than women (1:27:32 versus 1:34:19 h:min:s, respectively; P < 0.001, η = 0.373), there was a large effect of age group on time (P < 0.001, η = 0.590) and the gender difference was larger in the older than in the younger age groups (P < 0.001, η = 0.534). The age of peak performance for all finishers by 1-year interval age group was 40.3 and 39.6 years in all women and men, respectively. The top 10 finishers by 1-year interval age group achieved their peak performance in the age of 38.4 and 42.2 years in women and men, respectively. The age of peak performance was older and the age-related performance decline occurred earlier in marathon cross-country skiing, compared to road-based marathon running.
对1998年至2016年间参加“恩嘎丁滑雪马拉松”的197,825名运动员的人口统计学和成绩数据进行了分析。当考虑每个年龄组的所有完赛者时，时间上没有性别差异（女性为2:59:00，男性为2:59:09小时:分钟:秒；P = 0.914，η < 0.001），年龄组对时间的主要影响微不足道（P < 0.001，η = 0.007）。当考虑每个年龄组的前10名完赛者时，男性比女性快（分别为1:27:32和1:34:19小时:分钟:秒；P < 0.001，η = 0.373），年龄组对时间有很大影响（P < 0.001，η = 0.590），并且年龄较大组的性别差异比年龄较小组更大（P < 0.001，η = 0.534）。按1岁间隔年龄组划分，所有完赛者的最佳成绩年龄在所有女性和男性中分别为40.3岁和39.6岁。按1岁间隔年龄组划分，前10名完赛者在女性和男性中分别在38.4岁和42.2岁时达到最佳成绩。与公路马拉松赛跑相比，马拉松越野滑雪的最佳成绩年龄更大，与年龄相关的成绩下降出现得更早。
