“…In our study, all subjects finished the test without difficulty or premature stop. We found a 62-m (13 %) improvement in WD in T-CHD group, in agreement with results of Bittner et al [4], who showed a 15 % improvement in subjects with different heart diseases. Redelmeier et al [23] reported that an improvement in WD of at least 54 m is clinically significant, in that it represents a noticeable modification to the functional status.…”

Six-Minute Walking Test to Assess Exercise Tolerance and Cardiorespiratory Responses During Training Program in Children With Congenital Heart Disease

This study assessed the exercise tolerance and the cardiorespiratory responses to a training program by the six-minute walk test (6'WT) in children with congenital heart disease (CHD). Seventeen cardiac and 14 healthy children performed maximal cardiopulmonary exercise test (CPET) and 6'WT. Reliability of 6'WT was assessed in all subjects (test-retest) by Bland-Altman plots. Cardiac subjects were randomly divided in training (T-CHD) and control groups (C-CHD). T-CHD underwent an individualized training exercise at the ventilatory threshold (VT) intensity during 12 weeks. We found that the 6'WT is a reliable and reproducible test. CHD children walked a lower distance than healthy children before training (472.5 +/- 18.1 vs. 548.8 +/- 7.7 m, respectively, p < 0.001). Likewise, power output, oxygen uptake (V.O (2)), and heart rate (HR) at the maximum and the VT levels, were significantly lower in patients (p < 0.001). After training, a significant improvement of walking distance (WD) was shown in T-CHD (529.6 +/- 15.3 vs. 467.7 +/- 17.1 m, p < 0.001). The power output, VO2, HR, and V.E increased slightly (6 to 10 %, p > 0.05) at peak exercise and significantly at ventilatory threshold level (p < 0.05) in T-CHD. Significant relationships between WD and VO2max as well as VO2 at VT were founded (p < 0.05). We concluded that the 6'WT is a useful and reliable tool in the assessment and follow-up of functional capacity during rehabilitation program in children with CHD.

“…Women did not achieve the same increase in functional capacity as men even after adjusting for age, race, and baseline 6-minute walk distance, consistent with the previous observation that male gender was an independent predictor of improvement in 6-minute walk distance in multivariate modeling. 20 In contrast, women achieved greater improvements in triglycerides and diet score during CR, and these benefits remained significantly greater among women than among men 1 year later. It is possible that retention and implementation of dietary advice may be greater among women because women traditionally have a greater role in cooking for themselves and the family.…”

“…Functional capacity was assessed by the 6-minute walk test. 19,20 Patients were classified into 3 clinical risk categories (low, intermediate, and high) as recommended by the American Association of Cardiovascular and Pulmonary Rehabilitation, 21 and a comorbidity score was calculated as previously published. 22 Depression screening using the Beck Depression Inventory II (BDI-II) was added to the database in October 1998.…”

“…However, studies have demonstrated that submaximal levels of walking in short intervals are achievable and safe for patients with chronic diseases and functional limitations. For example, patients who have had recent myocardial infarctions, coronary revascularization procedures (Bittner, Sanderson, Breland, Adams, & Schumann, 2000), or knee osteoarthritis (Evcik & Sonel, 2002) have benefited from brief bouts of walking. Physical activity at submaximal effort has also been associated with reductions in cancer risk related to tobacco smoking (Colbert et al, 2001;Mao et al, 2003).…”

Since the effects of tobacco smoke are so detrimental to health, growing consideration has been given to the development of harm reduction strategies for those smokers who are unable or unwilling to stop using tobacco. The term harm reduction refers to a policy, strategy, or particular intervention that assumes continued use of an undesired behavior and aspires to lower the risk of adverse consequences associated with the continuation of this addictive behavior. Up to this point, tobacco harm reduction interventions have focused on reducing tobacco-related harm through the utilization of innovative tobacco products, reduced tobacco consumption, and pharmaceutical medications. With the possible exception of medicinal nicotine products, these strategies remain unproven and thus far no scientific or medical literature exists to suggest these harm reduction strategies reduce tobacco-related exposure, morbidity, or mortality. Consequently, a need exists for broadening the range of potentially effective harm reduction strategies. This preliminary review suggests that physical activity has the potential to become one such strategy. Of the eight principles that characterize a harm reduction strategy, all are at least partially satisfied by physical activity. Further, emerging evidence indicates that physical activity may delay the occurrence of disease and premature death initiated by tobacco consumption. Significant concerns remain regarding the practicality of physical activity as a harm reduction strategy and the extent to which participation in physical activity may be used to justify continued smoking.
