In young women archers menarche does not come late, as it does in many other athletes · What changed https://matteocampagna.com/en/registry/health/menarche-young-women-archers Changes to this claim in Matteo Campagna's evidence registry: its status, its year-by-year history, revisions of the page. en-gb Claim page revised, version 2https://matteocampagna.com/en/registry/health/menarche-young-women-archersThere is a single piece of data that counts, and a small one. At a Korean sports high school, among 124 athletes from thirteen disciplines, the first period arrives on average at 13.6 years against 12.4 in 345 girls of the same age who do no sport, while the peak in height growth falls at around eleven and a half years in both groups: the delay is therefore not down to slower maturation overall, it opens up between the growth peak and menarche. When the evaluation built on the non-athletes is applied to each girl, the delay shows up in almost every sport, clearly in taekwondo and athletics, but not in the eight archers, and none of the four girls who still had no period shot a bow (they were three gymnasts and one taekwondo athlete). The authors put it down to a sport that does not place a heavy load on the whole body and does not shift the balance between lean and fat mass. Eight girls, though, are too few to say that archery protects: a small but real delay would not have been seen, and neither the training load nor the nutritional status of each girl was recorded. A 2020 questionnaire given to 142 Turkish women archers puts the recalled first period at 13.27 years on average, but with no girls of the same age for comparison, no record of when they started shooting and in a journal with questionable editorial standards, so it cannot say whether there is a delay.claim:menarca-giovani-arciere:revision:2026-06-06:2Sat, 06 Jun 2026 08:00:00 GMT History updated: entry for 2020, Reportedhttps://matteocampagna.com/en/registry/health/menarche-young-women-archers#storiaA questionnaire given to 142 Turkish women archers, mostly adults, puts the recalled first period at 13.27 years on average, the same in all three age groups. Everything needed to interpret it is missing, though: a group of girls of the same age who do not shoot, the age at which they had taken up archery, the training load; and the study appears in a journal with questionable editorial standards, which in this registry does not decide a status. It stays as context, and the status still rests on the eight Korean archers of 2011: reported.claim:menarca-giovani-arciere:history_entry:2026-06-05:2020Fri, 05 Jun 2026 08:00:00 GMT "In young women archers menarche does not come late, as it does in many other athletes" added to the registry as Reportedhttps://matteocampagna.com/en/registry/health/menarche-young-women-archersclaim:menarca-giovani-arciere:new_claim:2026-01-23:riportatoFri, 23 Jan 2026 08:00:00 GMT
