As the existence of a late reaction in exercise induced asthma is controversial, peak expiratory flow (PEF) was measured for up to 13 hours after a running test in 404 consecutive young male army conscripts undergoing assessment of their asthma. In 294 subjects (73%) the immediate post-exercise fall in PEF was 10% or more; the mean (SD) fall in PEF in this group was 27% (15%). Nine patients wit...

We examined changes in P wave height in lead 2 of an ECG obtained during progressive exercise in 23 patients with COPD, and measured both P wave changes and pulmonary hemodynamics during exercise at a constant workload corresponding to approximately 50 to 60 percent of VO2 max in nine patients. The P wave response to exercise (delta P/delta VO2, %/ml/min), estimated by the relationship between ...

This study examined the effects of different exercise intensities and durations on bone mineral density (BMD) and bone strength in senescence-accelerated mouse prone 6 (SAMP6) and determined the involvement of the Wnt signaling pathway in exercise-induced osteogenesis. Three-month-old male SAMP6 mice were randomly assigned to different speeds of treadmill running exercise representing low, medi...

Endurance training-induced changes in hemodynamic traits are heritable. However, few genes associated with heart rate training responses have been identified. The purpose of our study was to perform a genome-wide association study to uncover DNA sequence variants associated with submaximal exercise heart rate training responses in the HERITAGE Family Study. Heart rate was measured during steady...

to evaluate physical activity of pregnant women before and after acog guideline study. four hundred and eighty-five pregnant women enrolled in this before-after study. they were asked to study acog guideline. a structured questionnaire filled by women at first visit and the last visit in the prenatal clinic.type, frequency, duration and anxiety about doing exercises during pregnancy period. bef...

purpose the purpose of this study was to examine the effects of ramadan fasting on circulating levels of interleukin-12 (il-12) after a brief maximal exercise. methods nine subjects performed a wingate test on three different occasions: (i) the first week of ramadan (1wr), (ii) the fourth week of ramadan (4wr), and (iii) three weeks after ramadan (ar). blood samples were taken before, immediate...

QUESTION Is progressive resistance training as effective as aerobic training of similar duration in sedentary older adults with diabetes mellitus? DESIGN A randomised trial with concealed allocation, assessor blinding and intention-to-treat analysis. PARTICIPANTS Sixty people with Type 2 diabetes mellitus with glycosylated haemoglobin (HbA1c) between 8% and 10% in the past month. INTERVEN...

Background. Because acute exercise increases systemic catecholamines, we sought to determine whether exercise training would alter daily or exercise-related catecholamine release and inactivation. Methods and Results. In 24-hour urine collections, catecholamines and metabolites provided indexes of overall oxidative deamination, sulfation, and O-methylation. Plasma catecholamines, the sulfoconju...

Acute physical exercise and repeated exercise stimuli affect whole-body metabolic and immunologic homeostasis. The aim of this study was to determine plasma protein profiles of trained (EET, n = 19) and untrained (SED, n = 17) individuals at rest and in response to an acute bout of endurance exercise. Participants completed a bicycle exercise test at an intensity corresponding to 80% of their V...
