海南临高人身体成分分析

2014年11月在海南省临高县测量了415例(男性为211例,女性为204例)临高人的体重、身高及体成分指标值。临高人男性体重、身高、总肌肉量、四肢肌肉量、躯干肌肉量、推定骨量、总能量代谢、水分率、内脏脂肪等级都大于女性,但总体脂率、躯干及四肢脂肪率则小于女性。随年龄增长,临高男性总体脂率、内脏脂肪等级、躯干脂肪率呈线性上升,而身高、总肌肉量、推定骨量、总能量代谢、躯干肌肉量呈线性下降。男性躯干部位的脂肪逐渐堆积,这导致临高男性总脂肪率、内脏脂肪等级、躯干脂肪率与年龄呈显著线性正相关。随年龄增长,临高女性总体脂率、总肌肉量、BMI、内脏脂肪等级、身体大部分部位的脂肪率、四肢肌肉量都呈线性增长(P<0.05或P<0.01)。女性的躯干和四肢脂肪率共同增加导致总脂肪率的增大,四肢肌肉量的增加导致总肌肉量的增大。临高男性体脂不发达,体脂率小于邻近汉族。临高人体脂发育情况与黎族较为接近。临高人肌肉较为发达。

Body Composition Analysis of the Lingao People in Hainan Province

By measuring their body heights, weights and body composition index of 415 Lingao people(male 211, female 204) in Hainan Province in November 2014, we find that the Lingao males are greater than the females in weights, heights, total body muscle mass(TBMM), limbs muscle mass(LMM), trunk muscle mass(TMM), estimated bone mass(EBM), total energy metabolism(TEM), percent body water(PBW) and visceral fat level(VFL), whereas the Lingao males are less than the females in percent body fat(PBF), percent trunk fat (PTF) and percent limbs fat(PLF). Along with the age growth, the Lingao males’ PBF, VFL and PTF increase linearly, whereas their heights, TBMM, bone mass, TEM and TMM decrease linearly. The gradual accumulation of fat in the male torso which causes PBF, VFL, PTF had a significant positive linear correlation with their age. With the increase of age, Lingao females’ PBF, TMM, BMI, VFL, most parts of the body fat percentage, LMM have linear growths(P<0.05 or P<0.01). The increase of the female percent torso and limbs fat results in an increase of their PBF, and the increase of LMM cause the enlargement of their TMM. The Lingao males are not developmental in body fat and are less than the adjacent Han in PBF. Both the Lingao people and Li ethnicity are very similar in body fat development. The Lingao people’s muscle are more developmental.
