这项研究的目的是确定在大规模有氧运动训练后久坐行为的变化。参与者包括自己选择跑马拉松的成年人。在7个评估期(−3、−2和马拉松前1个月、马拉松后2周内、马拉松后+1、+2和+3个月)，连续7天对久坐行为、总活动量和体力活动(PA)强度进行评估。使用Stata mi模块对模型进行多重补偿数据拟合。采用随机截距广义最小二乘(GLS)回归模型，通过7波重复测量来确定久坐行为的变化。23名受试者(平均值±SX：34.4±2.1岁，23.0±1.9%脂肪，15名女性，8名男性)完成了这项研究。马拉松跑完全程时间为185~344分钟，平均(253.2±9.6)分钟。与比赛前两个月(训练高峰期)相比，比赛后一个月纵轴上的总计数减少了1,729,414人。此外，在同一时期，每分钟计数减少了252.7次·分钟−1。在考虑了年龄、性别、体脂百分比、穿衣时间、马拉松完赛时间和以前的马拉松经历后，每天久坐的行为在七个评估期内没有变化。这项前瞻性研究支持PA和久坐行为是不同的这一概念，表明高水平的有氧训练不会影响久坐行为。
The aim of this study is to determine changes in sedentary behaviour in response to extensive aerobic exercise training. Participants included adults who self-selected to run a marathon. Sedentary behaviour, total activity counts and physical activity (PA) intensity were assessed (Actigraph GT3X) for seven consecutive days during seven assessment periods (−3, −2, and —1 month prior to the marathon, within 2 weeks of the marathon, and +1, +2, and +3 months after the marathon). Models were fitted with multiple imputation data using the STATA mi module. Random intercept generalized least squares (GLS) regression models were used to determine change in sedentary behaviour with seven waves of repeated measures. Twenty-three individuals (mean ± Sx: 34.4 ± 2.1y, 23.0 ± 1.9% fat, 15 women, 8 men) completed the study. Marathon finishing times ranged from 185 to 344 minutes (253.2 ± 9.6 minutes). Total counts in the vertical axis were 1,729,414 lower one month after the race, compared with two months prior to the race (peak training). Furthermore, counts per minute decreased by 252.7 counts·minute−1 during that same time period. Daily sedentary behaviour did not change over the seven assessment periods, after accounting for age, gender, per cent body fat, wear time, marathon finishing time, and previous marathon experience. This prospective study supports the notion that PA and sedentary behaviours are distinct, showing that sedentary behaviour was not impacted by high levels of aerobic training.
