The purpose of this study is to investigate the effects of strenuous exercises on resting heart rate, blood pressure, and maximal oxygen uptake. To achieve the purpose of the study, a total of 30 subjects were selected, including 15 people who performed continued regular exercises and 15 people as the control group. With regard to data processing, the IBM SPSS Statistics ver. 21.0 was used to c...

Maximal exercise heart rate (HRmax) is reduced after acclimatization to hypobaric hypoxia. The low HRmax contributes to reduce maximal cardiac output (Qmax) and may limit maximal O2 uptake (VO2max). The objective of these experiments was to test the hypothesis that the reduction in Qmax after acclimatization to hypoxia, due, in part, to the low HRmax, limits VO2max. If this hypothesis is correc...

BACKGROUND In professional soccer, a significant amount of training time is used to improve players' aerobic capacity. However, it is not known whether soccer specific training fulfils the criterion of effective endurance training to improve maximal oxygen uptake, namely an exercise intensity of 90-95% of maximal heart rate in periods of three to eight minutes. OBJECTIVE To determine whether ...

OBJECTIVE Functional Capacity Evaluations (FCEs) have been utilized by healthcare professionals for over twenty years to provide an objective assessment of an individual's ability to safely perform functional work activities. Biomechanical observations have been established as a reliable method of determining safe maximal performance levels during dynamic lift testing in FCEs. The purpose of th...

OBJECTIVES This study sought to examine the prognostic importance of chronotropic incompetence among patients referred for stress echocardiography. BACKGROUND Although chronotropic incompetence has been shown to be predictive of an adverse prognosis, it is not clear if this association is independent of exercise-induced myocardial ischemia. METHODS Consecutive patients (146 men and 85 women...

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...

Introduction: This study aims at analyzing the effect of 12 weeks physical exercise (30 minutes for three days a week: 70-85% of the maximum heart rate) on variations of inflammation markers in middle-aged women's Coronary Heart diseases (CHDs). Methods: In this study a total of 40 subjects including 40-55 years old women were selected purposively and were divided into two experimental and c...
