Abstract

This study was performed to determine the influence of single and repetitive exercise on nitric oxide (NO) concentration in the lung. Exhaled NO concentration (FE_NO) was measured during a constant-flow exhalation manoeuvre (170 ml · s^?1, against a 10 cmH₂O resistance) in healthy individuals (a) during and after a 100-min square-wave exercise of between 25 and 60% of maximal power output (n = 18) and (b) before and after five successive prolonged exercises (90 – 120 min, 75 – 85% of maximal heart rate) separated by 48 or 24 h (n = 8). The FE_NO0.170 was decreased during and after the 100-min exercise test (mean± s _[xbar] : 58.5 ± 3.7% and 76.7 ± 5.2% of resting value at 90 min of exercise and 15 min post-exercise, respectively; P < 0.05). The five successive exercise sessions induced a similar post-exercise FE_NO0.170 decrement (73.1 ± 2.9% of resting value 15 min post-exercise), while basal FE_NO0.170 values were not different between the five sessions (P > 0.05). These results suggest that prolonged exercise induces a reduction in NO concentration within the lung that lasts for several minutes after the end of exercise. However, repetitive exercises (at least every 24 h) allow complete NO recovery from one session to another. The implication of such a decrease in NO availability within the lung remains to be clarified.  相似文献   

Containing Sotomayor: Rhetorics of personal restraint,judicial prudence,and diabetes management     

Jeffrey A. Bennett 《Quarterly Journal of Speech》2018,104(3):257-278

This essay explores how rhetorics of diabetes management informed Sonia Sotomayor’s judicial persona during her ascent to the Supreme Court. Sotomayor’s confirmation hearings were clouded famously by institutional racism and sexism. She was accused repeatedly by congressional Republicans of being intemperate, emotional, and illogical in a judicial sphere that prizes circumspection, deliberateness, and collegiality. As part of a larger strategy to counter such claims, the Obama administration forwarded her lifetime of managing type-one diabetes as proof of personal control, and by extension judicial prudence. This strategic invocation of intersectionality, using a disability to rhetorically “contain” race and gender, helped to successfully resituate universal notions of wisdom and secure Sotomayor a seat on the nation’s highest court.  相似文献

目的：探讨瑜伽运动对慢性下腰痛中老年女性患者腰部肌肉功能的影响。方法：将40例慢性下腰痛中老年女性患者分为瑜伽组和对照组;对照组接受基础治疗,瑜伽组接受基础治疗的基础上进行12周的瑜伽练习,观察两组治疗前后左右竖脊肌、多裂肌的表面肌电信号的变化。结果：两组治疗后,均能提高直立位、俯卧位、前屈位、飞燕式的MF值（P＜0.05）,且瑜伽组显著大于对照组（P＜0.05）;两组均能降低直立位、俯卧位、前屈位、飞燕式的RMS值（P＜0.05）,且瑜伽组明显小于对照组（P＜0.05）。结论：进行瑜伽练习的基础治疗和单纯基础治疗均能提高腰部肌肉功能状态,降低腰部肌肉的疲劳程度,但进行瑜伽练习的基础治疗比单纯基础治疗效果更优。  相似文献   

The Use of Online Support Groups to Seek Information about Chronic Illness: Applying the Theory of Motivated Information Management     

Elisa Kanter  Sam M. Dorros 《Communication quarterly》2019,67(1):100-121

The growing number of adults living with chronic illness, combined with the increased availability of illness-specific online support groups, is changing the way individuals seek information about their chronic illnesses. This study utilized elements of the theory of motivated information management (TMIM) to examine how individuals decide to seek information about their chronic illness from online support groups. Adults with chronic illness who had visited at least one online support group in the last six months completed an online survey. Structural equation model findings revealed that, although uncertainty discrepancy about a chronic illness did not predict negative emotional response, both target efficacy and communication efficacy were positively related to information-seeking. Findings aid in explaining specific processes individuals go through when deciding to visit online support groups to gather information about their chronic illnesse, but cannot conclusively support TMIM in this context.  相似文献
