  • Upper limit of fat‐free mass in humans

    Open Access•Masakatsu Kondo, Takashi Abe et al.•ARTICLE•American Journal of Human Biology•1994

    If limitations exist in skeletal dimensions, fat‐free mass (FFM) might have an upper limit. To explore the upper limit to FFM, 37 professional Japanese Sumo wrestlers, 14 highly trained bodybuilders, and 26 untrained men were investigated for body composition (fat mass and FFM) and cross‐sectional areas (CSA) of limb muscles, by hydrodensitometry and ultrasound, respectively. Mean % fat of Sumo wrestlers, bodybuilders, and untrained subjects were…

  • The limb composition in the growing generation

    Open Access•Tetsuo Fukunaga, Hiroaki Kanehisa et al.•ARTICLE•The Journal of Anthropological…•1989

    本研究では7歳から18歳までの男子127名,女子124名を対象に,超音波法により体肢の筋および皮下脂肪断面積を測定し,それらにおける発育変化について検討した。男子の場合に,皮下脂肪断面積は7歳から12歳にかけて増加し,12歳から14歳の間では減少するが,15歳以降は再び増加した。女子の皮下脂肪断面積は,7歳から11歳までほとんど変化せず,11歳から14歳の間に急激に増加し,15歳以降はほぼ一定であった。筋断面積は男子では7歳から18歳まで年齢が進むにつれ増加するが,女子では上腕が14歳まで,他の部位が16,17歳まで増加がみられた。皮下脂肪および筋断面積における性差は13歳以降に顕著となった。筋に対する皮下脂肪の面積比は男子の場合に12歳から14歳にかけて減少したが,他の年齢ではほとんど変化がみられなかった。女子のそれは7歳から12歳にかけて減少し,12歳から15歳の間では増加し,15歳以降はほぼ一定であった。このことは男子では7歳から12歳,14歳から18歳の各年齢間では皮下脂肪断面積…

  • The Muscle Strength of Japanese Children in Relation to Relative Growth

    Open Access•Hiroaki Kanehisa, Naoya TSUNODA et al.•ARTICLE•The Journal of Anthropological…•1989

    The pourpose of this study was to investigate the ralative growth of muscle strength to body height as well as muscle area. Subjects were 141 boys and 130 girls from 6 to 19 years old. Maximum isometric strengths of flexion and extension at elbow and knee were measured by using Cybex II isokinetic dynamometer. Cross-sectional areas of the flexor and the extensor muscles in upper arm as well as thigh were measured by using ultrasonic apparatus. Mu…
