BACKGROUND:North American indigenous populations experience higher rates of obesity and chronic disease compared with nonindigenous populations. Improvements in musculoskeletal fitness can mitigate negative health outcomes, but is not well understood among indigenous populations. This review examines musculoskeletal fitness measures among North American indigenous populations. METHODS:A total of 1632 citations were evaluated and 18 studies were included. RESULTS:Comparisons of musculoskeletal fitness measures between North American indigenous men and boys and women and girls were generally not reported. The greatest left and right combined maximal grip strength and maximal leg strength among Inuit boys and men and girls and women were observed among 20-29 years age group. Maximal combined right and left grip strength declined from 1970 to 1990, by an average of 15% among adults and 10% among youth. Maximal leg extension among Inuit has declined even further, averaging 38% among adults and 27% among youth from 1970 to 1990. Inuit men demonstrate greater grip strength and lower leg strength than Russian indigenous men, whereas Inuit women demonstrate greater leg strength. CONCLUSIONS:Further research is needed to better understand physical fitness among indigenous peoples and the potential for improving health and reducing chronic disease risk for indigenous peoples through physical fitness.

背景:与非土著居民相比,北美土著居民的肥胖和慢性病发病率更高。肌肉骨骼适应性的改善可以减轻负面的健康后果,但在土著居民中尚未得到很好的理解。这项审查审查了北美土著人口中的肌肉骨骼适应措施。
方法:总共对1632篇文献进行了评估,包括18项研究。
结果:一般没有报道北美土著男子和男孩与妇女和女孩之间的肌肉骨骼健身措施的比较。在20至29岁年龄段的人群中,因纽特人男女中最大的左右最大握力和最大腿部力量相结合。从1970年到1990年,左右手的最大组合力量下降了,成年人平均下降15%,青年平均下降10%。因纽特人的最大伸腿幅度甚至进一步下降,从1970年到1990年,成年人平均平均伸腿38%,青年平均27%。因纽特人男性比俄罗斯土著男子表现出更大的握力和更低的腿部力量,而因纽特人女性则表现出更大的腿部力量。
结论:需要进行进一步的研究,以更好地了解土著人民的身体适应性,以及通过身体适应性改善土著人民健康和减少慢性病风险的潜力。
