Åldern för maximal prestation i längdskidåkning

[King Grub]

The age of the best endurance performance has been well investigated in flat city running marathons. However, we have no knowledge about the age of peak marathon performance in cross-country skiing, which would be of great practical value for athletes and coaches. Therefore, the aim of the present study was to examine the age of peak marathon performance in cross-country skiing. Participants were 162,991 men and 34,833 women competing between 1998 and 2016 in the 'Engadin Ski Marathon'. We considered for both women and men the fastest and all finishers in 1-year age intervals. The men-to-women ratio increased across ages (r2=0.55, P<0.0001). Men (44.27+/-0.03 years, 15.73+/-0.01 km/h) were 5.98+/-0.07 years older and 2.14+/-0.02 km/h faster (P<0.0001) than women (38.29+/-0.06 years, 13.58+/-0.01 km/h). Considering the fastest participants in 1-year age intervals, the fastest speed for men (30.33 km/h) was achieved at the age of 29 years and for women (28.76 km/h) at the age of 24 years. Considering all participants, the fastest speed for men (17.69 km/h) was observed at the age of 18 years, whereas for women (15.76 km/h) at the age of 17 years. In summary, for athletes and coaches, the age of peak performance in cross-country skiers competing in a marathon distance was much younger and closer to the peak of aerobic capacity than what was found by previous studies in marathon road runners.

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, η2 < 0.001) and the main effect of age group on time was trivial (P < 0.001, η2 = 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, η2 = 0.373), there was a large effect of age group on time (P < 0.001, η2 = 0.590) and the gender difference was larger in the older than in the younger age groups (P < 0.001, η2 = 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.

Haha, har tänkt åka det loppet nästa år.

Ett förtydligande gällande loppet är att det är i fri stil dvs skate. Det kan ha viss påverkan.
