Increasing the energy expenditure above the elementary level of metabolism by undertaking regular physical activity causes body mass reduction and its maintenance at a healthy level.
To remote assessment of the level of physical activity in a group of overweight and obese individuals.
The research was conducted in the Department of Rehabilitation at the Institute of Rural Health, Lublin, Poland, and included a group of 514 volunteers of both genders (38 ±12 years). The examined group was divided into three subgroups depending on the body mass index (BMI) level (I - normal, II - overweight, III - obese). The level of physical activity at home was assessed based of the short version of the International Physical Activity Questionnaire (IPAQ), conducted by means of a mobile application, and was compared with data registered by the accelerometer of a smartphone.
The IPAQ-assessed level of the physical activity expressed in MET-min/week amounted to the following values: group I: 5190.38 ±6629.84, group II: 5099.53 ±6380.97, group III: 3939.31 ±4000.73; and the caloric cost (cal × week) amounted to: group I: 5825.47 ±7512.99, group II: 7204.09 ±9187.96), and group III: 7002.10 ±7296.22. Registered levels of physical activity (MET-min/week) were lower than IPAQ-assessed: in group I (3741.24 ±3958.29), in group II (2447.72 ±2156.44) and in group III (1927.42 ±1790.85) (p < 0.05).
The average values of energy expenditure showed a declining tendency, together with an increase in the BMI. On the other hand, the total weekly caloric cost showed the lowest average values in the group with normal body mass.
通过进行有规律的体育活动，使能量消耗高于基础代谢水平，可导致体重减轻并维持在健康水平。
对一组超重和肥胖个体的身体活动水平进行远程评估。
研究在波兰卢布林农村卫生研究所康复科进行，纳入了514名男女志愿者（38±12岁）。根据体重指数（BMI）水平，将被检查组分为三个亚组（I组 - 正常，II组 - 超重，III组 - 肥胖）。基于国际体力活动问卷（IPAQ）的简短版本，通过移动应用程序评估在家中的身体活动水平，并与智能手机加速度计记录的数据进行比较。
以代谢当量 - 分钟/周表示的IPAQ评估的身体活动水平如下：I组：5190.38±6629.84，II组：5099.53±6380.97，III组：3939.31±4000.73；热量消耗（卡路里×周）如下：I组：5825.47±7512.99，II组：7204.09±9187.96，III组：7002.10±7296.22。记录的身体活动水平（代谢当量 - 分钟/周）低于IPAQ评估值：I组（3741.24±3958.29），II组（2447.72±2156.44）和III组（1927.42±1790.85）（p<0.05）。
能量消耗的平均值呈现下降趋势，同时BMI增加。另一方面，每周总热量消耗在正常体重组中显示出最低的平均值。
