INTRODUCTION Arterial stiffness and heart rate recovery (HRR) following exercise testing have emerged as variables holding significant prognostic value in a number of populations. The purpose of the present study is to examine the relationship between arterial stiffness and HRR in a group of apparently healthy subjects. METHODS Two hundred and nine apparently healthy subjects underwent maxima...

STUDY OBJECTIVE To clarify the effect of cold air on exercise capacity in COPD. DESIGN Cycle ergometer tests under different environmental conditions. SETTING Pulmonary function laboratory and an environmental chamber at a university hospital. PARTICIPANTS Eighteen patients with stable COPD; 14 completed the study. INTERVENTIONS A preliminary cycle ergometer test followed by two increme...

We examined whether exercise testing with measurement of cardiac output during maximal exercise can provide additional prognostic information for medically treated patients in whom left ventricular function and extent of coronary artery disease are known. We followed 1034 patients with normal or mildly impaired left ventricular function; 410 of these patients (group 1) had single-vessel disease...

Objective: For many years in herbal medicine the antihypertensive and lowering blood lipid properties of Achillea wilhelmsii (A. wilhelmsii) have been suggested. In the present study the impacts of the plant extract on rabbit’s blood pressure and heart rate have been investigated. Materials and Methods: Twelve NWZ rabbits weighed 2-3 kg were randomly divided into two groups of 6 rabbits. The t...

[Purpose] This study was conducted to determine the influence of Taekwondo as security martial arts training on anaerobic threshold, cardiorespiratory fitness, and blood lactate recovery. [Subjects and Methods] Fourteen healthy university students were recruited and divided into an exercise group and a control group (n = 7 in each group). The subjects who participated in the experiment were sub...

background: hawthorn species decreases blood pressure and relaxes precontracted vessels. this study aimed at examining the antihypertensive effect and related mechanisms of hydroalcoholic extract of crataegus azarolus subspecies aronia fruit in rats with renovascular hypertension. methods: six groups of male sprague-dawley rats, each containing 6 to 8 rats, were studied. the groups comprised of...

The purpose of this initial study was to evaluate a new wheelchair ergometer (WCE) and exercise test protocol for the detection of coronary artery disease in men with lower limb disabilities. Forty-nine patients (63 +/- 9 yr) completed WCE tests without complications. Peak heart rate was 84 +/- 15% (mean +/- SD) of age-predicted maximum and peak double product was 223 +/- 62 x 10(2). The specif...

Using a meta-analytic approach, we recently reported that the rate of decline in maximal oxygen uptake (VO2 max) with age in healthy women is greatest in the most physically active and smallest in the least active when expressed in milliliters per kilogram per minute per decade. We tested this hypothesis prospectively under well-controlled laboratory conditions by studying 156 healthy, nonobese...
