RESUMO

OBJECTIVES: Cardiac rehabilitation (CR) programmes are standard of care for patients following a coronary event. While such exercise-based secondary prevention programme do offer benefits, they are used by less than 30% of eligible patients and attrition within these programmes is high. This project is a nested qualitative assessment of a pilot programme considering Tai Chi (TC) as an alternative to CR. We hypothesised that TC may overcome several key barriers to CR. METHODS: A semistructured focus group agenda was used to assess three key domains of feasibility: (1) patients' experiences, (2) reasons/barriers for not having attended CR and (3) any improvements in physical activity and other secondary outcomes (quality of life, weight, sleep). A thematic analysis was used to better understand the key concepts. RESULTS: This high-risk group of patients reported that they enjoyed TC exercise, and felt confident and safe doing it. TC practice was reported to support other types of physical activity allowing for a generalisation of positive effects. DISCUSSION: This analysis is consistent with published reports of TC practice improving mood and psychological well-being. Qualitative methods allowed us to find emergent experiential reports of behaviour change factors found in established behaviour change theories.

RESUMO

BACKGROUND: More than 60% of patients decline participation in cardiac rehabilitation after a myocardial infarction. Options to improve physical activity (PA) and other risk factors in these high-risk individuals are limited. We conducted a phase 2 randomized controlled trial to determine feasibility, safety, acceptability, and estimates of effect of tai chi on PA, fitness, weight, and quality of life. METHODS AND RESULTS: Patients with coronary heart disease declining cardiac rehabilitation enrollment were randomized to a "LITE" (2 sessions/week for 12 weeks) or to a "PLUS" (3 sessions/week for 12 weeks, then maintenance classes for 12 additional weeks) condition. PA (accelerometry), weight, and quality of life (Health Survey Short Form) were measured at baseline and 3, 6, and 9 months after baseline; aerobic fitness (stress test) was measured at 3 months. Twenty-nine participants (13 PLUS and 16 LITE) were enrolled. Retention at 9 months was 90% (LITE) and 88% (PLUS). No serious tai chi-related adverse events occurred. Significant mean between group differences in favor of the PLUS group were observed at 3 and 6 months for moderate-to-vigorous PA (100.33 min/week [95% confidence interval, 15.70-184.95 min/week] and 111.62 min/week; [95% confidence interval, 26.17-197.07 min/week], respectively, with a trend toward significance at 9 months), percentage change in weight, and quality of life. No changes in aerobic fitness were observed within and between groups. CONCLUSIONS: In this community sample of patients with coronary heart disease declining enrollment in cardiac rehabilitation, a 6-month tai chi program was safe and improved PA, weight, and quality of life compared with a 3-month intervention. Tai chi could be an effective option to improve PA in this high-risk population. CLINICAL TRIAL REGISTRATION: URL: http://www.clinicaltrials.gov. Unique identifier: NCT02165254.

RESUMO

BACKGROUND: Community-based interventions that incorporate resistance training (RT) and dietary changes have not been extensively studied in overweight and obese older adults. The purpose of this investigation was to determine the effects of a community-based RT and dietary intervention on physical function and body composition in overweight and obese older adults. METHODS: Ninety-five overweight and obese (BMI=33.4±4.0 kg/m2) older adults aged 55-80 years completed an 8-week RT and dietary intervention at 4 Rhode Island senior centers. Participants performed RT twice-weekly using resistance tubing, dumbbells, and ankle weights. Participants also attended 1 weekly dietary counseling session on a modified Dietary Approaches to Stop Hypertension diet. Outcome measurements included anthropometrics, body composition, and physical function. RESULTS: There were small changes in body mass (-1.0±1.8 kg, P<.001), waist circumference (-5.2±3.8 cm, P<.001), and percent body fat (-0.5±1.4%, P<.001). In addition, significant improvements were observed in knee extensor torque (+7.9±19.1 N-m, P<.001), handgrip strength (+1.2±2.5 kg, P<.001), and 8-foot up-and-go test time (-0.56±0.89 s, P<.001). CONCLUSION: Community-based RT and dietary modifications can improve body composition, muscle strength, and physical function in overweight and obese older adults. Future investigations should determine if this intervention is effective for long-term changes.
