Background:Autonomic nervous system balance is altered in cystic fibrosis (CF), although its influence on physical fitness has been poorly explored.Objective:This study aimed to evaluate the association of heart rate variability (HRV) with exercise capacity and levels of daily physical activity in children and adolescents with mild-to-moderate CF.Methods:A cross-sectional study including individuals with CF aged 6–18 years, not under CFTR modulator therapy, was performed. Sociodemographic (age, sex) and clinical information (airway colonization, pancreatic insufficiency, and genotyping) were collected. In addition, exercise capacity (modified shuttle test — MST), lung function (spirometry), body composition (bioimpedance), levels of daily physical activity (5-day accelerometer), and HRV (both at rest and during the MST) were evaluated.Results:30 individuals (20 females) aged years, mean FEV%, were included. A sympathovagal balance (LF/HF) increase () during the MST was shown, indicating a predominance of sympathetic modulation. The standard deviation of all RR intervals (SDNN) and the high frequency (HF) index during exercise correlated significantly with FEV1 (, and , ; respectively). MST distance also correlated positively and significantly with SDNN (, ), square root of the mean of the sums of squares of frequencies between RR intervals greater than 50 ms — RMSSD (, ), low frequency — LF (, ), HF (, ), dispersion of points perpendicular to the short-term identity line — SD1 (, ) and negatively with LF/HF (, ). Regarding daily physical activity, SDNN at rest (, ) and exercise (, ) showed positive correlations with time in moderate-to-vigorous activities. When normalizing the SDNN and classifying individuals as normal or altered, those presenting altered SDNN showed poorest FEV1 () and lower exercise capacity ().Conclusion:HRV correlates with lung function, exercise capacity and levels of daily physical activity in children and adolescents with CF. The study highlights the influence of CF on autonomic function and suggests HRV measurement as an easy tool to be used in clinical settings as an alternative marker to monitor CF individuals. 相似文献

The relation between serum theophylline concentrations, effectiveness, tolerability and compliance were evaluated in 14 hospitalized elderly patients with broncho-obstructive pathology, using a new twice daily sustained release theophylline suspension compared to standard twice daily slow release tablets. The results showed that the mean theophylline serum concentration remains within the therapeutic range with both preparations. No significant difference exists between the two treatments with regard to effectiveness. Tolerability and compliance of the theophylline suspension, however, were higher. 相似文献

To investigate the influence of daily activity on changes in the physical fitness of people with post-stroke (cerebrovascular disorders) hemiplegia, we evaluated the follow-up exercise load test of 30 ambulatory male patients with post-stroke hemiplegia. Between the times of the two tests, patients had no special supervised training. They were advised by their physicians to exercise according to the result of an exercise-loading test. We determined peak oxygen uptake and O2 consumption at the ventilatory threshold point. After 9.4 months, the mean peak oxygen uptake improved significantly from 17.7 to 21.1 ml/min/kg, and ventilatory threshold point also improved significantly from 11.4 to 13.6 ml/min/kg. Among the nine subjects who returned to their jobs, subjects who previously went to their offices by public transportation showed more improvement in ventilatory threshold point level than did subjects who previously walked to their offices. Among the 21 subjects who did not return to work, those who exercised regularly (primarily by walking) showed more improvement of peak oxygen uptake level than did subjects who did not exercise regularly. In conclusion, people with hemiplegia who are living in the community can improve their physical fitness without formal supervised training by simply increasing their daily activities. 相似文献

The purpose of this study was to investigate the relationships between physical activity and walking speed in women 64 years of age and over. Data were gathered from 81 nondisabled women ranging from 64.0 to 94.5 years of age. The women were categorized as sedentary, community active, or exercisers based on a combination of their living situation and level of daily activity. Subjects walked over a 3.84-m recording surface at five different paces, ranging from walking as slowly as possible to walking as quickly as possible. Actual walking speed and length of steps were measured. Stepping frequency and step length relative to leg length were derived measures. Mean walking speeds ranged from 0.43 m/s at the very slow pace to 1.42 m/s at the very fast pace. The walking speeds at the very slow pace were significantly different among the three physical activity groups. At the very slow pace, women who exercised were able to walk significantly more slowly than the other women. The groups were not significantly different at any other pace. Normal walking speeds for all groups were slower than those previously reported for younger women, with the walking speed of the fastest pace of the elderly women being closer to the normal walking speed of younger women. The results of this study indicate that physical therapists need to utilize age-appropriate values as the standard when evaluating performance. [Leiper CI, Craik RL.

OBJECTIVE: The relationship between adenosine deaminase activity and plasma adenosine was examined in non-pregnancy as well as in singleton and twin pregnancies. METHODS: Whole-blood samples were taken from 11 singleton and 11 dichorionic twin pregnant women during the third trimester. The plasma adenosine levels were assayed with a modified high-performance liquid chromatographic method, while the adenosine deaminase levels were measured enzymatically. RESULTS: The adenosine deaminase and plasma adenosine levels were both higher in twin pregnancies compared to singleton and non-pregnancies. CONCLUSION: Increased plasma adenosine is not due to decreased serum adenosine deaminase levels in twin pregnant women. 相似文献

目的 探讨老年人脂蛋白脂酶(LPL)活性改变及其与血脂浓度之间的关系.方法测定40例老年人甘油三酯、总胆固醇、低密度脂蛋白胆固醇(LDL-C)、高密度脂蛋白胆固醇(HDL-C)及肝素后LPL活性,以45例非老年人作为对照,并用直线相关回归研究LPL活性与血脂水平的关系.结果老年人甘油三酯、总胆固醇及LDL-C浓度均显著高于非老年人(P<0.05或<0.01);肝素后LPL活性明显低于非老年人(P<0.05);老年人肝素后LPL活性与甘油三酯浓度呈负相关(r=-0.513,P<0.01),与HDL-C水平则呈正相关(r=0.390,P<0.05).结论老年人LPL活性降低会引起高甘油三酯血症伴有低HDL-C浓度,并可能是一种导致动脉粥样硬化的危险因素. 相似文献

目的 探讨老年人不同年龄段甘油三酯的改变对其血流变的影响.方法 收集895例佛山地区60以上老年人体检资料,首先分为男女对照组(男747人,女148人),并以年龄段分为3个组别,以61~70岁为对照组,与71~80岁、80岁以上组别进行对比,通过统计分析,研究甘油三酯(TG)与全血黏度高切(WBACH)、全血黏度低切(WBACL)、全血还原黏度高切(WBOACH)、全血黏度低切(WBOACL)、血浆黏度(BPAC)等密切的关系.结果 男性甘油三酯(TG)在对照组达到高峰,女性则以71~80岁组别达到高峰,随后稍有下降,但各组别仍然高于正常.而老年人血流变指标则以对照组为最高,随后也稍有下降,但各组别仍然高于正常,与甘油三酯(TG)呈正相关.结论 老年人甘油三酯的升降造成血液的黏稠度的变化,从而引起血流变各项指标的改变,对预防老年人由于高血脂所引起的心脑血管等疾病有十分重要的作用. 相似文献
