The purpose of this study was to assess the effectiveness of a 4-week intervention in which an online personal activity monitor (Gruve-Technologies™) was used to reduce sedentary behavior among sedentary adults.
Eighteen, sedentary adult volunteers (12 men, six women, mean age 29 ± 4.0 years) were recruited to participate in the study. Time spent in sedentary activities and light-, moderate-, and vigorous-intensity physical activity and energy expenditure were assessed during waking hours using the monitor and the 7-day SLIPA Log at both baseline and post-intervention.
A significant decrease of 33% (3.1 h/day; p < 0.001) was found between the time spent in sedentary activities measured at baseline (9.4 ± 1.1 h/day) and at the end of the 4-week intervention (6.3 ± 0.8 h/day). Consequent to the changes in sedentary time, significant increases were found in the amount of time spent in light- (45% (2.6 h/day), p < 0.001), moderate- (33% (1 h/day) p < 0.001), vigorous-intensity physical activity (39% (0.16 h/day), p < 0.001), and energy expenditure (47% (216.7 kcal/day), p < 0.001).
This monitor contributes to a meaningful reduction in time spent in sedentary activities and has a large effect on energy expenditure and physical activity patterns.
本研究旨在评估一项为期4周的干预措施的效果，该措施使用在线个人活动监测器（Gruve-Technologies™）来减少久坐不动的成年人的久坐行为。
招募了18名久坐不动的成年志愿者（12名男性，6名女性，平均年龄29±4.0岁）参与该研究。在基线期和干预后，使用该监测器和7天的SLIPA日志在清醒时间评估久坐活动、轻度、中度和剧烈强度身体活动的时间以及能量消耗。
在基线期测量的久坐活动时间（9.4±1.1小时/天）与4周干预结束时（6.3±0.8小时/天）之间，发现久坐活动时间显著减少了33%（3.1小时/天；p<0.001）。由于久坐时间的变化，发现轻度身体活动时间（45%（2.6小时/天），p<0.001）、中度身体活动时间（33%（1小时/天），p<0.001）、剧烈强度身体活动时间（39%（0.16小时/天），p<0.001）以及能量消耗（47%（216.7千卡/天），p<0.001）均有显著增加。
该监测器有助于显著减少久坐活动时间，并对能量消耗和身体活动模式有很大影响。
