Objective: To perform a systematic review of completion rates of cardiac rehabilitation (CR) in adults aged 18 to 50 yr and describe how core components were reported, measured, and tailored to those under 50 yr.

Review methods: Database search of MEDLINE, Embase, Emcare, PsycINFO, CINAHL, Scopus, and the Cochrane Library based on keywords, including articles from January 1, 1990. The last search was performed on April 21, 2023. Following the Preferred Reporting Items for Systematic Review and Meta-Analyses protocol, eligible articles contained adults (aged between 18 and 50 yr) who had participated in a CR program.

Summary: Out of the articles screened (n = 24,517), 33 reports across 31 independent studies were considered eligible (n = 1958 patients aged ≤50 yr). Cardiac rehabilitation completion rates ranged from 64% to 100%; however, only 5 studies presented a completion rate definition. The length of the program ranged from 7 d to 20 wk, with most (65%) ranging between 6 and 12 wk. While the studies included in this systematic review indicated relatively high rates of completing CR, these are likely to overrepresent the true completion rates as few definitions were provided that could be compared to completion rates used in clinical practice. This systematic review also found that all interventions prescribed exercise (eg, aerobic alone or combined with resistance training or yoga) but had very limited inclusion or description of other integral components of CR (eg, initial assessment and smoking cessation) or how they were assessed and individualized to meet the needs of younger attendees.

Purpose: The objective of this study was to determine the relationship between aortic stiffening and brachial and central ambulatory blood pressure (AMBP) in a nonclinical sample of middle-aged and older adults (MA/O). We hypothesized aortic stiffness would be positively associated with 24-hr, daytime, and nighttime brachial and central AMBP.

Methods: Fifty-one participants aged ≥50 yr (21 males and 30 females, mean age 63.4 ± 9.0 yr) with a body mass index <35 kg/m 2 who also had a resting brachial blood pressure (BP) <160/100 mmHg with or without BP medications were recruited for this cross-sectional analysis. All participants underwent measures of aortic stiffness (carotid-femoral pulse wave velocity [cfPWV]) and 24-hr AMBP monitoring. Bivariate correlations assessed the relationship between cfPWV, brachial, and central AMBP. Partial correlations were used to independently adjust for traditional cardiovascular disease (CVD) risk factors including age, sex, waist circumference, glucose, and augmentation index normalized to heart rate 75 bpm, a surrogate measure of arterial stiffness, and in a multivariable combined model.

Results: Nighttime brachial systolic BP ( r = 0.31) and central systolic BP ( r = 0.30) were correlated with cfPWV in the multivariable combined model ( P ≤ .05). Nighttime brachial pulse pressure and central pulse pressure were correlated with cfPWV after independently adjusting for all CVD risk factors ( P ≤ .05, all) but not when combined in the multivariable model ( P > .05).

Conclusions: Higher nighttime brachial and central AMBP with older age are related, in part, to greater aortic stiffening. Therefore, interventions to lower or prevent aortic stiffening may also lower nighttime BP in MA/O adults to lower CVD risk.

Purpose: While research demonstrates low levels of physical activity (PA) among adults living with atrial fibrillation (AF), there is limited evidence investigating sex differences in moderate to vigorous intensity physical activity (MVPA) and sedentary time in this population. The primary aim was to examine sex differences in MVPA levels and sitting time between women and men with AF. Secondary aims explored sex differences in sociodemographic factors, outcome expectations, and task self-efficacy toward PA levels.

Methods: This was a subanalysis of the CHAMPLAIN-AF cohort study. Women and men with AF completed a survey, including the Short-Form International Physical Activity Questionnaire.

Results: A total of 210 women (median = 66.0 yr: 95% CI, 63.5-68.0) and 409 men (median = 66.0 yr: 95% CI, 64.0-67.0) were included. No sex differences were observed in median weekly MVPA (60 min/wk: 95% CI, 0-120 in women vs 120 min/wk: 95% CI, 85-150 in men) and daily sitting time (5.5 hr/d: 95% CI, 5.0-6.0 in women vs 6.0 hr/d: 95% CI, 5.0-6.0 in men). Women engaged in significantly less vigorous-intensity PA than men ( P = .03) and demonstrated significantly lower task self-efficacy ( P < .01). Significant positive correlations in PA levels with outcome expectations (mostly weak) and task self-efficacy (mostly strong) were observed in both sexes.

Conclusion: Most women and men with AF did not meet the global MVPA guidelines but met the sitting time recommendation. Women presented with lower vigorous-intensity physical activity levels and confidence than men. Strategies to increase physical activity behavior, considering sociodemographic factors and task self-efficacy, are needed and may differ between sexes.

Purpose: The physiological adaptations stimulated by a sauna bath (SB) are similar to those produced by moderate- or high-intensity physical activity (PA), but the relationship between SB and cardiorespiratory fitness (CRF) is not clear. The objective of this study was to evaluate the cross-sectional and longitudinal associations between frequency and duration of SB with CRF.

Methods: Baseline SB habits were assessed in 2012 men aged 42 -61 yr. CRF was directly measured using a respiratory gas exchange analyzer during cardiopulmonary exercise testing at baseline and 11 yr later. The associations of SB frequency and duration with baseline and 11-yr levels of CRF were examined using robust regression analyses adjusted for several confounders, including lifestyle factors such as PA.

Results: In baseline analysis, a unit increase in sauna sessions/wk was associated with an increase in CRF 0.30 mL/kg/min (standard error [SE]: 0.14; P = .034). Alternatively, compared with a single sauna sessions/wk, 2-3 and 4-7 sauna sessions/wk was each associated with significant increases in levels of CRF: 0.84 mL/kg/min (SE: 0.32; P = .008) and 1.17 mL/kg/min (SE: 0.57; P = .041), respectively. In longitudinal analysis, frequent SB was associated with increases in 11-yr CRF levels, but this was only significant for 2-3 sauna sessions/wk compared with a single sauna sessions/wk: 1.22 mL/kg/min (SE: 0.59; P = .038). Duration of SB was not significantly associated with CRF levels in cross-sectional and longitudinal analyses.

Conclusions: Frequent SB may improve levels of CRF independently of PA. These results warrant replication in robust definitive randomized controlled trials.

Purpose: Chronic obstructive pulmonary disease (COPD) is characterized by decreasing exercise capacity and deteriorating quality of life (QoL). Recent evidence indicates that combining exercise with manual therapy (MT) delivers greater improvements in exercise capacity than exercise alone in moderate COPD. The aim of this study was to investigate whether this combination delivers similar results in mild COPD.

Methods: A total of 71 participants aged 50-65 yr with mild COPD were randomly allocated to two groups: exercise only (Ex) or MT plus exercise (MT + Ex). Both groups received 16 wk of exercise with the MT + Ex group also receiving 8 MT sessions. Lung function (forced vital capacity [FVC] and forced expiratory volume in the 1 st sec [FEV 1 ]), exercise capacity (6-min walk test [6MWT]), and QoL (St George's Respiratory Questionnaire [SGRQ] and Hospital Anxiety and Depression Scale [HADS]) were measured at baseline, 4, 8, 16, 24, 32, and 48 wk.

Results: Although there was no difference in the mean effect over time between groups for lung function (FEV 1 , P = .97; FVC, P = .98), exercise capacity (6MWT, P = .98), and QoL (SGRQ, P = .41; HADS anxiety, P = .52; and HADS depression, P = .06), there were clinically meaningful improvements at 48 wk for 6MWT (30 m; 95% CI, 10-51 m; P < .001), SGRQ (6.3 units; 95% CI, 2.5-10.0; P < .001), and HADS anxiety (1.5 units; 95% CI, 0.3-2.8 units; P = .006) across the entire cohort.

Conclusions: While adding MT to Ex did not produce any additional benefits, exercise alone did deliver sustained modest improvements in exercise capacity and QoL in mild COPD.
