Twenty-six healthy women homemakers residing in the metropolitan city of Bombay were studied on a treadmill and a cycle ergometer to determine their aerobic capacity (VO2 max) with a view to evaluating their cardio-respiratory fitness and ascertaining the job-demand-fitness-compatibility in household activities. The VO2 max was found to be significantly higher in treadmill experiments, i.e. 15% in absolute value and 18% in relative value, as compared with that obtained by cycle ergometry (p < 0.001). A much higher difference was observed in values derived from the two methods on the same subjects (i.e. 28% in absolute value and 31% in relative value). Thus, the VO2 max obtained from treadmill experiments may be regarded as the maximal aerobic power or the highest oxygen uptake that an individual can attain during exercise, which in the sample of the present study was recorded as 1.90 l min-1 (33.9 ml kg-1 min-1). The findings also revealed that age and body weight have a direct influence on VO2 max, which was found to be significantly correlated, positively with the latter and negatively with the former (p < 0.01 in both cases). The physiological job-demand of household activities seems to be compatible in relation to the VO2 max of the homemakers.
对居住在孟买大都市的26名健康女性家庭主妇进行了跑步机和自行车测力计测试,以确定她们的有氧能力(最大摄氧量),目的是评估她们的心肺适能,并确定家务活动中的工作需求与适能的匹配度。结果发现,跑步机实验中的最大摄氧量显著更高,即绝对值高15%,相对值高18%,与自行车测力计测试结果相比(p < 0.001)。在同一受试者身上,两种方法得出的值差异更大(即绝对值高28%,相对值高31%)。因此,跑步机实验得出的最大摄氧量可被视为个体在运动过程中能够达到的最大有氧功率或最高摄氧量,在本研究样本中记录为1.90升/分钟(33.9毫升/千克·分钟)。研究结果还表明,年龄和体重对最大摄氧量有直接影响,并发现与最大摄氧量显著相关,与体重呈正相关,与年龄呈负相关(两种情况均为p < 0.01)。家务活动的生理工作需求似乎与家庭主妇的最大摄氧量相匹配。
