Introduction: Although cardiac patients obtain favorable cardiovascular outcomes and reduced risk of mortality when participating in cardiac rehabilitation (CR), it is well established that most do not typically achieve recommended amounts of daily physical activity (PA) solely through participation in CR. Therefore, the purpose of this study was to examine the relative effectiveness of three different individually tailored interventions designed to increase PA in cardiac patients attending CR. Hypothesis: We assessed the hypothesis that cardiac patients attending long-term CR who receive pedometer feedback (PF) or motivational messaging (MM) will achieve higher levels of PA than patients who receive usual care (UC) recommendations. Methods: A total of 99 (77 men and 22 women, 61.5±10.6 years, BMI 30.6 ± 5.1 kg/m2) patients entering a long-term CR program completed a 12-week PA intervention. Patients were randomized to: UC (time-based recommendation), PF, MM, or PF with individualized MM (PF+MM). Both PF groups were given a goal of increasing step counts/day by 10% of the individual’s baseline value each week. If the goal for the week was not reached, the same goal was used for the next week. PA was assessed for 7 days with Kenz Lifecorder PLUS monitors (Suzukan, Co, LTD, Nagoya, Japan) prior to beginning CR and on the 12 th week of the intervention. Criteria for acceptable PA data were daily wear time > 10 hours on a minimum of 4 days (including at least 1 weekend day) with daily PA > 1000 steps. Results: A two-way ANOVA for change in PA from baseline to 12 th week of the intervention for the 4 groups revealed a significant time and group interaction. Post-hoc testing showed significant increases for both PF and PF+MM, however, no significant change for UC or MM. Conclusion: The findings from this study demonstrate that using PF feedback is superior to the usual time-based recommendations patients are given in CR. CR programs can assist patients in increasing their daily PA by encouraging pedometer use with individualized step goals.

During adolescence, physical activity (PA) decreases with potentially serious, long-term consequences for physical and mental health. Although barriers have been identified as an important PA correlate in adults, research on adolescents’ PA barriers is lacking. Thus reliable, valid scales to measure adolescents’ PA barriers are needed. We present two studies describing a broad range of PA barriers relevant to adolescents with a multidimensional approach. In Study 1, 124 adolescents (age range = 12 – 24 years) reported their most important PA barriers. Two independent coders categorized those barriers. The most frequent PA barriers were incorporated in a multidimensional questionnaire. In Study 2, 598 adolescents (age range = 13 – 21 years) completed this questionnaire and reported their current PA, intention, self-efficacy, and negative outcome expectations. Seven PA barrier dimensions (leisure activities, lack of motivation, screen-based sedentary behavior, depressed mood, physical health, school workload, and preconditions) were confirmed in factor analyses. A multidimensional approach to measuring PA barriers in adolescents is reliable and valid. The current studies provide the basis for developing individually tailored interventions to increase PA in adolescents.

Abstract Objective Our work aimed to investigate the association between vigorous physical activity and visit-to-visit systolic blood pressure variability (BPV). Methods We conducted a post hoc analysis of SPRINT (Systolic Blood Pressure Intervention Trial), a well-characterized cohort of participants randomized to intensive (<120 mmHg) or standard (<140 mmHg) SBP targets. We assessed whether patients with hypertension who habitually engage in vigorous physical activity would have lower visit-to-visit systolic BPV compared with those who do not engage in vigorous physical activity. Visit-to-visit systolic BPV was calculated by standard deviation (SD), average real variability (ARV), and standard deviation independent of the mean (SDIM) using measurements taken during the 1-, 2-, 3-, 6-, 9- and 12-month study visits. A medical history questionnaire assessed vigorous physical activity, which was divided into three categories according to the frequency of vigorous physical activity. Results A total of 7571 participants were eligible for analysis (34.8% female, mean age 67.9±9.3 years). During a follow-up of 1-year, vigorous physical activity could significantly reduce SD, ARV, and SDIM across increasing frequency of vigorous physical activity. There were negative linear trends between frequency of vigorous physical activity and visit-to-visit systolic BPV. Conclusions Long-term engagement in vigorous physical activity was associated with lower visit-to-visit systolic BPV.

Background Home-based interventions might facilitate the lifelong uptake of a physically active lifestyle following completion of a supervised phase II exercise-based cardiac rehabilitation. Yet, data on the long-term effectiveness of home-based exercise training on physical activity and exercise capacity are scarce. Objective The purpose of the TeleRehabilitation in Coronary Heart disease (TRiCH) study was to compare the long-term effects of a short home-based phase III exercise programme with telemonitoring guidance to a prolonged centre-based phase III programme in coronary artery disease patients. The primary outcome was exercise capacity. Secondary outcomes included physical activity behaviour, cardiovascular risk profile and health-related quality of life. Methods Ninety coronary artery disease patients (80 men) were randomly assigned to 3 months of home-based (30), centre-based (30) or a control group (30) on a 1:1:1 basis after completion of their phase II ambulatory cardiac rehabilitation programme. Outcome measures were assessed at discharge of the phase II programme and after one year. Results Eighty patients (72 (91%) men; mean age 62.6 years) completed the one-year follow-up measurements. Exercise capacity and secondary outcomes were preserved in all three groups ( Ptime > 0.05 for all), irrespective of the intervention ( Pinteraction > 0.05 for all). Eighty-five per cent of patients met the international guidelines for physical activity ( Ptime < 0.05). No interaction effect was found for physical activity. Conclusion Overall, exercise capacity remained stable during one year following phase II cardiac rehabilitation. Our home-based exercise intervention was as effective as centre-based and did not result in higher levels of exercise capacity and physical activity compared to the other two interventions.

Purpose: Examine the association between neighborhood poverty histories and physical activity, and the moderation effect of family poverty and the mediation effect of built environments in such association. Design: A cross-sectional study of the Geographic Research on Wellbeing (2012-2013), a follow-up survey of statewide-representative Maternal and Infant Health Assessment (2003-2007). Setting: California. Participants: A total of 2493 women with children. Measures: Outcome measures are (1) daily leisure physical activity and (2) days of physical activity among children. An independent variable is poverty histories of census tract where the child resided. Mediators were mother-perceived social cohesion, mother-perceived neighborhood safety, distance to the closest park, and park acreage within 0.5 miles from the home. A moderator is family poverty. Analysis: Weighted regression analysis. Results: Family poverty was a significant moderator ( P < .05); poor children in neighborhoods with long-term moderate poverty, long-term high poverty, or increasing poverty (vs long-term low poverty) had greater odds of daily physical activity (odds ratio [OR] = 1.46, 1.50, 1.66, respectively). Nonpoor children in neighborhoods with long-term moderate poverty or increasing poverty (vs long-term low poverty) were associated with decreased odds of daily physical activity (OR = 0.61 and 0.44, respectively). Mediation associations were insignificant ( P > .05). Conclusion: The combined effect of family financial strains and neighborhood economic resources might prevent poor children in neighborhoods with long-term low poverty and decreasing poverty from utilizing health-promoting resources in neighborhoods.

Background. We determined the extent to which heart rate variability (HRV) responses to daily physical activity differ between subjects with and without chronic neck pain.Method. Twenty-nine subjects (13 women) with chronic neck pain and 27 age- and gender-matched healthy controls participated. Physical activity (accelerometry), HRV (heart rate monitor), and spatial location (Global Positioning System (GPS)) were recorded for 74 hours. GPS data were combined with a diary to identify periods of work and of leisure at home and elsewhere. Time- and frequency-domain HRV indices were calculated and stratified by period and activity type (lying/sitting, standing, or walking). ANCOVAs with multiple adjustments were used to disclose possible group differences in HRV.Results. The pain group showed a reduced HRV response to physical activity compared with controls (p=.001), according to the sympathetic-baroreceptor HRV index (LF/HF, ratio between low- and high-frequency power), even after adjustment for leisure time physical activity, work stress, sleep quality, mental health, and aerobic capacity (p=.02). The parasympathetic response to physical activity did not differ between groups.Conclusions. Relying on long-term monitoring of physical behavior and heart rate variability, we found an aberrant sympathetic-baroreceptor response to daily physical activity among subjects with chronic neck pain.
