The impact of Tai Chi and mind-body breathing in COPD: Insights from a qualitative sub-study of a randomized controlled trial.
PurposeChronic obstructive pulmonary disease (COPD) is associated with multiple psychosocial and behavioral factors. Prior research suggests that mind-body interventions may support the development and maintenance of healthy behaviors and improve health-related quality-of-life in such patients. We sought to qualitatively explore cognitive, psychosocial, and behavioral changes in patients with COPD who participated in two different mind-body interventions compared to an education control.MethodsWe analyzed semi-structured qualitative exit interviews from a prospective, randomized pilot trial (N = 123) investigating 12-weeks of Tai Chi (TC) vs. mind-body breathing (MBB) vs. education (EDU) control in patients with moderate-severe COPD. TC involved traditional movements, that integrate meditative breathing, while MBB focused mainly on meditative breathing techniques alone. Interviews were audio-recorded and transcribed verbatim. Qualitative analysis of randomly selected transcripts was performed by two independent reviewers using an iterative process to identify emergent themes informed by grounded theory methods until thematic saturation was reached.ResultsA total of 66 transcripts were reviewed (N = 22 TC, N = 22 MBB, N = 22 EDU). Participants were mean age = 68.1 years, GOLD Stage = 2.3, baseline FEV11 percent predicted mean (SD): 58% (13.4), 42.4% female. We identified six frequently mentioned themes: 1) overall awareness and understanding, 2) self-care knowledge, skills and behaviors, 3) behavior-related neurocognitive concepts, 4) physical function, 5) psychological well-being, and 6) social support/social function. Compared to EDU, more participants in TC and MBB noted improvements in awareness of self and the mind-body connection (e.g., body and breath awareness), knowledge of breathing techniques and integration of self-care skills with daily activities, self-efficacy for symptom management (particularly managing anxiety and dyspnea), acceptance of disease, physical function improvements (e.g., endurance, dyspnea, fatigue), and psychological well-being (particularly relaxation, emotion regulation and decreased reactivity). Compared to MBB, those in TC shared more intention to continue with self-care behaviors, physical activity self-efficacy, and improved flexibility. All three groups, including EDU, noted increased social support and knowledge of disease. Those in EDU, however, had fewer mentions of processes related to behavior change, and less concrete changes in neurocognitive, psychological, and physical function domains.ConclusionsMind-body interventions including meditative breathing may impact behavior-related neurocognitive and emotional factors that improve self-care management and support positive behavioral changes in patients with COPD.Trial registrationThis trial is registered in Clinical Trials.gov, ID number NCT01551953

The Effects of High Intensity Short Rest Resistance Exercise on Muscle Damage Markers in Men and Women
Within and between sexes, universal load prescription (as assigned in extreme conditioning programs) creates extreme ranges in individual training intensities. Exercise intensity has been proposed to be the main factor determining the degree of muscle damage. Thus, the purpose of this study was to examine markers of muscle damage in resistance-trained men (n = 9) and women (n = 9) from a high intensity (HI) short rest (SR) (HI/SR) resistance exercise protocol. The HI/SR consisted of a descending pyramid scheme starting at 10 repetitions, decreasing 1 repetition per set for the back squat, bench press, and deadlift, as fast as possible. Blood was drawn pre-exercise (pre), immediately postexercise (IP), 15 minutes postexercise (+15), 60 minutes postexercise (+60), and 24 hours postexercise (+24). Women demonstrated significant increases in interleukin 6 (IL-6; IP), creatine kinase (CK; +24), myoglobin (IP, +15, +60), and a greater relative increase when compared with men (+15, +60). Men demonstrated significant increases in myoglobin (IP, +15, +60, +24), IL-6 (IP, +15), CK (IP, +60, +24), and testosterone (IP, +15). There were significant sex interactions observed in CK (IP, +60, +24) and testosterone (IP, +15, +60, +24). Women completed the protocol faster (women: 34:04 ± 9:40 minutes, men: 39:22 ± 14:43 minutes), and at a slightly higher intensity (women: 70.1 ± 3.5%, men 68.8 ± 3.1%); however, men performed significantly more work (men: 14384.6 ± 1854.5 kg, women: 8774.7 ± 1612.7 kg). Overall, women demonstrated a faster inflammatory response with increased acute damage, whereas men demonstrated a greater prolonged damage response. Therefore, strength and conditioning professionals need to be aware of the level of stress imposed on individuals when creating such volitional high intensity metabolic type workouts and allow for adequate progression and recovery from such workouts
