This article reports results of a field test of work capacity on 30 male farmers ranging in age from 15-54. It involved a self-paced walk from the valley floor, up the mountain wall, and return, with heart rate monitoring. The route was 2.21 km long with a vertical rise of about 200 m. At its steepest, the grade was about 34 degrees, requiring long runs of steps cut into the mountain face. The purpose of this research was to determine whether biological and behavioral traits of individual men help to explain household economic productivity to which they contribute. The traits included anthropometry and a new measure of self-paced, voluntary work capacity (heart rate x time). Income per productive adult increased as did the relative fitness index (heart rate increase above resting x min taken to finish the course). However, the number of rice bundles earned per family, expected to increase with more fit workers, increased with the number of household adults and sitting height (adjusted R(2) = 0.392), but not with self-paced fitness markers.

本文报告了对30名年龄在15至54岁之间的男性农民进行工作能力现场测试的结果。测试内容为从谷底开始，沿着山壁向上行走并返回，全程由参与者自行控制节奏，同时进行心率监测。路线长度为2.21公里，垂直上升约200米。最陡峭处坡度约为34度，需要沿着在山体表面开凿的长段台阶奔跑。本研究的目的是确定个体男性的生物学和行为特征是否有助于解释他们对家庭经济生产力的贡献。这些特征包括人体测量学指标以及一项新的自行控制节奏的自愿工作能力指标（心率×时间）。每个有生产力的成年人的收入增加了，相对健康指数（高于静息心率的增加量×完成路线所需时间）也增加了。然而，每个家庭收获的稻捆数量预计会随着工人健康状况的提高而增加，但实际上它与家庭成年人数量和坐高有关（调整后的R² = 0.392），与自行控制节奏的健康指标无关。《美国人类生物学杂志》12:192 - 200，2000年。版权所有2000年威利 - 利斯公司。
