OBJECTIVE To determine the relation between functional capacity and heart rate response to exercise in patients with atrial fibrillation. SUBJECTS 73 consecutive patients with chronic atrial fibrillation. MAIN OUTCOME MEASURES Relation between functional capacity, measured as peak oxygen consumption (peak VO2; ml/min/kg), and heart rate at all stages of exercise in univariate and multivaria...

Background and objective: The peak heart rate (HRpeak) assessed in maximum laboratory tests has been used to determine the aerobic exercise intensity in field situations. However, HRpeak values may differ in field and laboratory situations, which can influence the relative intensity of the prescribed workloads. The objective of this study was to measure the HRpeak responses in laboratory and fi...

OBJECTIVE To determine prevalence of Exercise-induced Bronchospasm (EIB) in hockey players, who had represented or were aspiring to represent Pakistan at international level. METHOD An observational, cross-sectional study was done on the prevalence of EIB in national hockey players of Pakistan. All participants of the training camp (n = 27) players were included in this study, after obtaining...

abstract introduction: yoga as an exercise to improve the physical, psychological, social health condition, and promote the feeling of health in healthy people in the medical education community is considered. the aim of this research was to find the effect of 8 weeks yoga training on respiratory function and heart rate of non-athlete females. methods: 30 students of khorasgan azad university w...

Introduction: Good functional capacity has a high negative predictive value (NPV) in patients with known or suspected coronary artery disease (CAD) similar to a normal gated myocardial perfusion imaging (GMPI). Aim of this study was to evaluate NPV of functional capacity during treadmill exercise in patients with normal GMPI in Pakistani population. Methods: This was a prospective study which ...

background: systolic blood pressure recovery (rsbp) is of prognostic value for predicting the survival and co-morbidity rate in patients with coronary artery disease (cad). this study investigated the association between rsbp and exercise indices after complete cardiac rehabilitation program (cr) in a population-based sample of patients undergoing coronary artery bypass grafting (cabg). methods...

the present study aimed to assess changes in resting and maximum heart rates as primary indicators of cardiac autonomic function in metabolic syndrome (mets) patients and to determine their value for discriminating mets from non-mets. 468 participants were enrolled in this cross-sectional study and assessed according to the updated adult treatment panel iii (atp-iii) definition of mets. resting...
