PURPOSE
This cross-sectional study examined the mutual independent associations of sedentary behavior, lower intensity physical activity (LPA) and higher intensity physical activity (HPA) (an approximation of moderate to vigorous physical activity with cardiorespiratory fitness (CRF).
METHODS
Two thousand twenty-four participants were included from The Maastricht Study (mean ± SD age, 59.7 ± 8.1 yr; 49.6% men). With the activPAL3 activity monitor, we assessed sedentary time (ST), sedentary pattern variables (number of sedentary breaks, average sedentary bout duration, and number of prolonged sedentary bouts [≥30 min]), LPA, and HPA. CRF was calculated as maximum power output per kilogram body mass (Wmax·kg) estimated from a submaximal cycle ergometer test. Linear regression analyses and isotemporal substitution analyses were used to examine associations of ST, sedentary pattern variables, and HPA with CRF. Analyses were stratified by sex.
RESULTS
One hour of ST per day was associated with a lower Wmax·kg: Bmen = -0.03 (95% confidence interval [CI], -0.05 to -0.01) and Bwomen = -0.02 (95% CI, -0.04 to 0.00), independent of HPA. No statistically significant associations between sedentary patterns variables and CRF were observed. LPA was associated with a higher Wmax·kg: Bmen = 0.12 (95% CI, 0.07-0.17) and Bwomen = 0.12 (95% CI, 0.07-0.18). HPA was associated with a higher Wmax·kg: Bmen = 0.48 (95% CI, 0.38-0.58) and Bwomen = 0.27 (95% CI, 0.18-0.36). Replacing ST with LPA (Bmen, 0.08; 95% CI, 0.03-0.14; Bwomen, 0.10; 95% CI, 0.05-0.16) or with HPA (Bmen, 0.49; 95% CI, 0.39-0.59; Bwomen = 0.28; 95% CI, 0.19-0.36), but not with standing was associated with higher CRF.
CONCLUSIONS
Modest associations between sedentary behavior and CRF were observed. Replacing ST with LPA was associated with higher CRF, which could be of particular importance for individuals who cannot engage in HPA. Nonetheless, replacing ST with HPA was associated with greatest estimated change in CRF.
目的
本横断面研究探讨了久坐行为、低强度体力活动（LPA）和高强度体力活动（HPA）（近似于中等至剧烈体力活动）与心肺适能（CRF）之间的相互独立关联。
方法
纳入了来自马斯特里赫特研究的2024名参与者（平均年龄±标准差为59.7±8.1岁；男性占49.6%）。使用activPAL3活动监测仪，我们评估了久坐时间（ST）、久坐模式变量（久坐间断次数、平均久坐时长以及久坐持续时间≥30分钟的次数）、LPA和HPA。CRF通过次极量蹬车试验估算的每千克体重最大功率输出（Wmax·kg）来计算。采用线性回归分析和等时替代分析来检验ST、久坐模式变量和HPA与CRF之间的关联。分析按性别分层。
结果
每天1小时的ST与较低的Wmax·kg相关：男性B=-0.03（95%置信区间[CI]，-0.05至-0.01），女性B=-0.02（95%CI，-0.04至0.00），独立于HPA。未观察到久坐模式变量与CRF之间存在统计学显著关联。LPA与较高的Wmax·kg相关：男性B=0.12（95%CI，0.07 - 0.17），女性B=0.12（95%CI，0.07 - 0.18）。HPA与较高的Wmax·kg相关：男性B=0.48（95%CI，0.38 - 0.58），女性B=0.27（95%CI，0.18 - 0.36）。用LPA（男性B，0.08；95%CI，0.03 - 0.14；女性B，0.10；95%CI，0.05 - 0.16）或HPA（男性B，0.49；95%CI，0.39 - 0.59；女性B = 0.28；95%CI，0.19 - 0.36）替代ST，但不是站立，与较高的CRF相关。
结论
观察到久坐行为与CRF之间存在适度关联。用LPA替代ST与较高的CRF相关，这对于无法进行HPA的个体可能尤为重要。尽管如此，用HPA替代ST与CRF的估计变化最大相关。
