Health research often focuses on moderate and vigorous intensity physical activity while neglecting low-intensity habitual activities. Our aim was to understand habitual physical activity in women from a transitioning economy using a physical activity monitor.
This study investigated physical activity in 68 healthy premenopausal women (age 18-46) in rural Poland using FitBit One activity trackers for 1 week. Standard anthropometric techniques were used to measure height, weight, and body fat. Daily physical activity data were analyzed for step counts as well as duration and intensity.
This sample of rural Polish women traveled a mean of 8428 (SD = 2650) steps per day. Time spent lightly active, fairly active, and very active were measured as 337.1 (SD = 87.8), 19.6 (SD = 30.5), and 6.7 (SD = 8.6) minutes per day, respectively. Total time active and time spent lightly active were associated with daily steps (P < 0.001 for both), and time lightly active increased with age (P = 0.02). No other significant relationships were observed between physical activity measures and BMI, age, or body fat.
In this sample, women spend a significant amount of time engaged in light-intensity physical activity and travel a relatively high number of steps per day. Our data suggest that in this population, total daily activity does not depend on age in women between 18 and 46. We suggest that measurement methods which include low-intensity activity may better characterize habitual physical activity in women who are expected to be performing large amounts of domestic labor.
健康研究通常侧重于中等和剧烈强度的体力活动,而忽略了低强度的习惯性活动。我们的目的是使用活动监测器了解转型经济体中女性的习惯性体力活动。
本研究使用 FitBit One 活动追踪器对波兰农村地区的 68 名健康绝经前女性(年龄 18-46 岁)进行了 1 周的身体活动调查。使用标准人体测量技术测量身高、体重和体脂。对日常体力活动数据进行分析,以计算步数以及持续时间和强度。
该样本中,农村波兰女性平均每天行走 8428(SD=2650)步。轻度活动、中度活动和剧烈活动的时间分别为 337.1(SD=87.8)、19.6(SD=30.5)和 6.7(SD=8.6)分钟/天。总活动时间和轻度活动时间与每天的步数显著相关(两者均 P<0.001),轻度活动时间随年龄增加而增加(P=0.02)。未观察到体力活动测量值与 BMI、年龄或体脂之间存在其他显著关系。
在该样本中,女性花大量时间进行低强度体力活动,每天行走相对较多的步数。我们的数据表明,在这个人群中,18 至 46 岁女性的总日常活动量与年龄无关。我们建议,包括低强度活动的测量方法可能更能描述预计要进行大量家务劳动的女性的习惯性体力活动。
