Indices of physiological performance in the field under natural working conditions were measured in 46 Sudanese Gezira villagers and related to exercise performance under controlled laboratory conditions. The effect of Schistosoma mansoni infection on energy expenditure in the field was also investigated. A highly significant positive association between the maximal aerobic power output (VO2 max) measured in the laboratory with energy expenditure in the field (r = + 0.51, p less than 0.001) and with changes in body weight during work (r = 0.41, p less than 0.01) was found. The villagers' energy expenditure in field work amounted to 25-28 KJ/min, which corresponded to more than 50% of their predicted VO2 max. They maintained that relative work level for more than an hour. The differences in energy expenditure between moderately infected and non-infected villagers with schistosomiasis did not attain statistical significance but the number of non-infected subjects on which the comparison was based was small.
对46名苏丹杰济拉村民在自然工作条件下的田间生理表现指标进行了测量，并将其与在可控实验室条件下的运动表现相关联。还研究了曼氏血吸虫感染对田间能量消耗的影响。研究发现，实验室测量的最大有氧功率输出（VO2 max）与田间能量消耗（r = + 0.51，p < 0.001）以及工作期间体重变化（r = 0.41，p < 0.01）之间存在高度显著的正相关。村民们在田间工作中的能量消耗为25 - 28千焦/分钟，这相当于他们预测的VO2 max的50%以上。他们保持这种相对工作水平超过一小时。中度感染血吸虫病的村民与未感染村民之间的能量消耗差异未达到统计学显著水平，但进行比较所依据的未感染受试者数量较少。
