SED (Table 2 ). Though estimates varied little, percentage of time spent in SED differed significantly across trimesters ( P = .048) with the first trimester being the highest and the second trimester being the lowest. Prolonged SED was stable across pregnancy. When not sedentary, women spent about

outcome, respectively. Discussion The main findings of this study were: (a) Personal and environmental barriers remained stable over time, and (b) personal lack of money were associated with decreased LLPA and increased SB. Personal barriers displayed greater stability over time, in contrast to
Kinematic and Electromyography Responses to Increasing Proprioception Demand and a Lack of Visual Feedback in Healthy, Middle-Aged Women Tested on an Unstable Platform

al., 1998 ; Strotmeyer et al., 2009 ; Ward et al., 2015 ). These deficiencies are compensated by increased vision reliance ( Choy et al., 2003 ; Hurley et al., 1998 ; Maki et al., 1994 ). Modeling the torque values, Peterka ( 2002 ) concluded that healthy subjects control their balance on a stable base
Attentional Focus Strategies Can Improve Performance of Postural Control in Runners

). Moreover, the increase in the difficulty of the postural task can be more sensitive to the effects of attentional focus strategies ( Park et al., 2015 ). For that reason, a stable and unstable surface (foam) was used in this study. Furthermore, it was expected that the difference in postural control

posture reduces perceptual sensitivity of visual and vestibular information ( Treffner, Barrett, & Petersen, 2002 ), and thus may compromise a driver’s capacity to appropriately control actions, such as steering ( Riccio, 1995 ). In other words, a stable posture provides a stable frame of reference for
Longitudinal Associations Between Sedentary Behavior and Depressive Symptoms in Adolescent Girls Followed 6 Years

results of the cross-lagged panel analysis are displayed in Table 3 . First, the basic model (model 1) with autoregressive paths and within-wave residual correlations fit the data well. All the autoregressive paths were significant and stable over time, indicating the individual differences remained
