This study examined the relationship between maximal aerobic work capacity (maximal oxygen uptake, V̇O max) and two variables (occupational group and history of cattle herding) related to the behavior of the Ngisonyoka Turkana, a group of East African pastoralists maintaining a traditional herding lifestyle. Maximal oxygen uptake was measured for 19 men aged 20-44 years using a Monark bicycle ergometer. In line with previous reports for East Africans, there was little difference among mean V̇O max for three Ngisonyoka age groups (20-29, 30-39, 40-49 years), P > 0.05. However, V̇O max varied with history of cattle herding [defined as either (1) presently herding cattle, (2) had formerly herded cattle, or (3) had never herded cattle], P < 0.01. Maximal oxygen uptake also varied with occupational group (defined as junior herder, senior herder, herdowner [= former herder], or impoverished herdowner [= resumed herder]), P < 0.05. Thus, culturally defined work history and occupational group are positively associated with V̇O max, and may be useful in field studies of the effects of past and present activity levels on aerobic capacity. © 1994 Wiley-Liss, Inc.
本研究调查了最大有氧工作能力（最大摄氧量，V̇O₂max）与两个变量（职业群体和放牧牛群的经历）之间的关系，这两个变量与恩吉索尼卡图尔卡纳人的行为有关，该群体是一群维持传统放牧生活方式的东非牧民。使用莫纳克自行车测力计对19名年龄在20 - 44岁的男性进行了最大摄氧量测量。与之前关于东非人的报告一致，三个恩吉索尼卡年龄组（20 - 29岁、30 - 39岁、40 - 49岁）的平均V̇O₂max之间几乎没有差异，P>0.05。然而，V̇O₂max随放牧牛群的经历而变化[定义为（1）目前放牧牛群，（2）曾经放牧过牛群，或（3）从未放牧过牛群]，P<0.01。最大摄氧量也随职业群体（定义为初级牧民、高级牧民、牧群所有者[=前牧民]或贫困牧群所有者[=重新开始放牧的人]）而变化，P<0.05。因此，文化定义的工作经历和职业群体与V̇O₂max呈正相关，并且可能在关于过去和当前活动水平对有氧能力影响的实地研究中有用。©1994威利 - 利斯公司。
