In a cross-sectional study, 30 retired female gymnasts were compared with 30 age-matched moderately active controls. Bone geometric and densitometric parameters were measured by pQCT at the distal epiphyses and shafts of the tibia, femur, radius, and humerus. Muscle cross-sectional areas were assessed from the shaft scans. Independent t-tests were conducted on bone and muscle variables to detect differences between the two groups. The gymnasts had retired for a mean of 6.1 ± 0.4 yr and were engaged in ≤2 h of exercise per week since retirement. At the radial and humeral shafts, cortical cross-sectional area (CSA), total CSA, BMC, and strength strain index (SSIpol) were significantly greater (13–38%, p ≤ 0.01) in the retired gymnasts; likewise, BMC and total CSA were significantly greater at the distal radius (22–25%, p ≤ 0.0001). In the lower limbs, total CSA and BMC at the femur and tibia shaft were greater by 8–11%, and trabecular BMD and BMC were only greater at the tibia (7–8%). Muscle CSA at the forearm and upper arm was greater by 15–17.6% (p ≤ 0.001) but was not different at the upper and lower leg. Past gymnastics training is associated with greater bone mass and bone size in women 6 yr after retirement. Skeletal benefits were site specific, with greater geometric adaptations (greater bone size) in the upper compared with the lower limbs.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1383670320114246784","@type":"Researcher","foaf:name":[{"@value":"Prisca Eser"}],"jpcoar:affiliationName":[{"@value":"Department of Rheumatology and Clinical Immunology/Allergology, University Hospital Bern, Berne, Switzerland"},{"@value":"Centre for Physical Activity and Nutrition Research, Deakin University, Burwood, Australia"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670320114246787","@type":"Researcher","foaf:name":[{"@value":"Briony Hill"}],"jpcoar:affiliationName":[{"@value":"Centre for Physical Activity and Nutrition Research, Deakin University, Burwood, Australia"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670320114246786","@type":"Researcher","foaf:name":[{"@value":"Gaele Ducher"}],"jpcoar:affiliationName":[{"@value":"Centre for Physical Activity and Nutrition Research, Deakin University, Burwood, Australia"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670320114246785","@type":"Researcher","foaf:name":[{"@value":"Shona Bass"}],"jpcoar:affiliationName":[{"@value":"Centre for Physical Activity and Nutrition Research, Deakin University, Burwood, Australia"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"08840431"},{"@type":"EISSN","@value":"15234681"}],"prism:publicationName":[{"@value":"Journal of Bone and Mineral Research"}],"dc:publisher":[{"@value":"Oxford University Press (OUP)"}],"prism:publicationDate":"2009-12-01","prism:volume":"24","prism:number":"12","prism:startingPage":"1981","prism:endingPage":"1988"},"reviewed":"false","dc:rights":["https://academic.oup.com/journals/pages/open_access/funder_policies/chorus/standard_publication_model"],"url":[{"@id":"https://api.wiley.com/onlinelibrary/tdm/v1/articles/10.1359%2Fjbmr.090521"},{"@id":"https://academic.oup.com/jbmr/article-pdf/24/12/1981/56574693/5650241207.pdf"}],"createdAt":"2009-05-19","modifiedAt":"2024-03-13","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1390282679899101312","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Allometry theory to create a standard value for bone mineral content for menstruating adult females and examination of usefulness"},{"@language":"ja","@value":"アロメトリー式を用いた一般成人有経女性の身体部位別の骨塩量の評価基準値と有用性の検証"},{"@language":"ja-Kana","@value":"アロメトリーシキ オ モチイタ イッパン セイジンユウケイ ジョセイ ノ シンタイ ブイ ベツ ノ ホネエンリョウ ノ ヒョウカ キジュンチ ト ユウヨウセイ ノ ケンショウ"}]},{"@id":"https://cir.nii.ac.jp/crid/1390861880807908224","@type":"Article","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Identification of functionally related adaptations in the trabecular network of the proximal femur and tibia of a bipedally trained Japanese macaque"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1359/jbmr.090521"},{"@type":"CROSSREF","@value":"10.1537/ase.2307142_references_DOI_HHFp7g9je5zmJj8f8wjZRTTYxsA"},{"@type":"CROSSREF","@value":"10.7600/jspfsm.63.259_references_DOI_HHFp7g9je5zmJj8f8wjZRTTYxsA"}]}
