A study by Frisancho Velasquez and Sanchez demonstrated that subjects with short stature attained a greater maximal aerobic capacity than their counterparts of a larger body size when tested under identical conditions. The adaptations which have been made by these groups also have a downside to them.
This shows only temporary and reversible acclimatisation. This conundrum led to the development of the altitude training modality known as "Live-High, Train-Low", whereby the athlete spends many hours a day resting and sleeping at one high altitude, but performs a significant portion of their training, possibly all of it, at another lower altitude.
Growth and development are one of the many areas affected. In the high altitude there are many environmental stresses that the people must endure. Here, we review recent advances in understanding the genetic architecture of adaptive human phenotypes based on insights from the studies of lactase persistence, skin pigmentation and high-altitude adaptation.
Further analysis in seven Tibetan populations 1, individuals indicates the prevalence of selective sweep across the Himalayan region. Most are two story structures whose interior dimensions are rather small. Using phenotype information, genome-wide association studies GWAS have successfully identified over 13, single nucleotide polymorphisms SNP associated with a wide range of traits, a portion of which are likely to be adaptive [ 31 ].
Frequently the first meter of the walls will be made of stone to resist erosion due to rain draining from the roof. The door is small and it"s height seldom exceeds 1. The Himalayas also have extensive pasture areas which are used by the nomadic and sedentary peoples. At sunset everyone goes to sleep.
Rooms may be employed for cookingsleeping, or storage Baker, Cold is another stress people of high altitudes must contend with. These few crops are threatened by drought, hail, frost, snow and erosion.
There are many non-physical adaptations that people make to help them adjust to the high altitude environment. There is an increase in the capillary network to aid diffusion of oxygen to the tissues.
Alternatively, SNP ascertainment may have overestimated the number of derived polymorphisms in dogs and underestimated the variation within wolves. The John Hopkins Press. Sample size is given in parenthesis and geographic elevation is shown for each population.

Children living at high altitudes develop a larger chest cavity by adulthood than children living at lower altitudes.
This is an example of ________. environmental adaptations that occur at the individual level.
On the theme of human adaptability, high altitude populations, variations in thermal tolerance and adaptations in ageing populations have all received recent investigation. Human Variations in High Altitude Populations Jessyca Caumo 26 november Thesis:The purpose of this paper is to describe the high altitude stresses and the general adaptations made by the Tibetan population in the Himalayas and the Quechua in the Andes.

Genetic Variations in Tibetan Populations and High-Altitude Adaptation at the Himalayas By applying the genomic approach and sampling multiple Tibetan populations of different geographic origins, Human genetic adaptation to high altitude.Determining different human variations in high altitude populations
