最近有人建议将久坐行为定义为花费少于1.5代谢当量（MET）的坐或斜躺活动，这与基于不充分的中等-剧烈活动或正式运动的传统观点不同。本研究旨在确定与常见久坐行为相关的能量消耗。25名非洲裔美国成年人（BMI 27.8±5.5）参与了代谢室研究。参与者在早上进入代谢室，估计他们的基础代谢率。他们吃了早餐，然后依次进行四种不同的久坐行为，每次持续30分钟。这些活动包括斜躺、看电视、阅读和在电脑上打字。下午，参与者被喂午餐，然后重复这些活动。结果表明，上午和下午的能量消耗值没有显着差异（p = 0.232）。 餐后斜倚的平均能量消耗（0.97 MET）略低于餐后看电视（p = 0.021）和打字（p<0.001），但差异显著。 坐着的人（即，阅读、打字、看电视）久坐活动。餐后状态下，几种常见久坐行为的能量消耗约为1.0 MET。结果支持的结论是，常见的久坐行为的平均能量成本是狭窄的带状约1.0 METs的餐后状态。
It has recently been recommended that sedentary behavior be defined as sitting or reclining activities expending less than 1.5 metabolic equivalents (METs), which is distinct from the traditional viewpoint based on insufficient moderate-vigorous activity or formal exercise. This study was designed to determine the energy expenditure associated with common sedentary behaviors. Twenty-five African American adults (BMI 27.8±5.5) participated in the metabolic chamber study. Participants entered the metabolic chamber in the morning and their basal metabolic rate was estimated. They were fed breakfast and then engaged in four different sedentary behaviors sequentially, lasting 30 minutes each. The activities included reclining, watching TV, reading, and typing on a computer. In the afternoon, the participants were fed lunch and then the activities were repeated. The results show that the energy expenditure values between the morning and afternoon sessions were not significantly different (p = .232). The mean energy expenditure of postprandial reclining (0.97 METs) was slightly, but significantly, lower than postprandial watching TV (p = .021) and typing (p<.001). There were no differences in energy cost (1.03–1.06 METs) between the seated (i.e., reading, typing, watching TV) sedentary activities. The energy expenditure of several common sedentary behaviors was approximately 1.0 METs in the postprandial state. The results support the conclusion that the average energy cost of common sedentary behaviors is narrowly banded around 1.0 METs in the postprandial state.
