The purpose of this study was to assess the validity and reliability of the Wattbike cycle ergometer against the SRM Powermeter using a dynamic calibration rig (CALRIG) and trained and untrained human participants. Using the CALRIG power outputs of 50-1 250  W were assessed at cadences of 70 and 90  rev x min(-1). Validity and reliability data were also obtained from 3 repeated trials in both t...

OBJECTIVE The aim of this study is to exam the effects of exercise modes on the systolic blood pressure and rate-pressure product during a gradually increasing exercise load from low to high intensity. METHODS Fifteen apparently healthy men aged 19 to 23 performed the graded exercise tests on cycle ergometer (CE) and treadmill (TM). During the low-to-maximal exercises, oxygen uptake (VO2), he...

BACKGROUND Exercise training has been incorporated into the international guidelines for the treatment of chronic obstructive pulmonary disease (COPD). However, the long-term efficacy of the training program for patients with advanced COPD has never been evaluated in Thailand. PURPOSE To determine the long-term efficacy of intensive cycle ergometer exercise program on various clinical paramet...

Objective The purpose of this study was to evaluate the effect of a cycle ergometer exercise program on exercise capacity and inspiratory muscle function in hospitalized patients with heart failure awaiting heart transplantation with intravenous inotropic support. Methods Patients awaiting heart transplantation were randomized and allocated prospectively into two groups: 1) Control Group (n=1...

PURPOSE To determine the reliability of a 30-s sprint cycle test on the Wattbike cycle ergometer. METHODS Over 3 consecutive weeks, 11 highly trained cyclists (mean ± SD; age 31 ± 6 y, mass 74.6 ± 10.6 kg, height 180.5 ± 8.1cm) completed four 30-s maximal sprints on a Wattbike ergometer after a standardized warm-up. The sprint test implemented a "rolling start" that consisted of a 60-s preloa...

OBJECTIVES In Finland, testing cardiorespiratory fitness (VO2max) is popular in health promotion programs and work ability evaluations. The most common instruments used for this purpose are the submaximal cycle ergometer test, and the 2-km walking test. However, limited data exist on the associations between VO2max and wellbeing in working age adults. The aim of the study was to evaluate how th...

The goal of this study was to assess the effects of amount of ergometer cycle training on Vo2max and body composition in overweight women. Forty-one sedentary premenopausal women, age 25 to 45 years, were randomly assigned in three groups. Cycle ergometer training consisted of one day per week for group A, two days per week for group B and three days per week for group C. Participants trained f...

blood hypercoagulability or thrombogenicity can be one of the main causes of the cardiovascular diseases in young population without traditional pathologic risk factors such as diabetes mellitus, hypertension or hyperlipidemia. the effect of aerobic exercise on coagulation and fibrinolysis has been studied extensively regarding to the effectivness of resistance exercises to increase functional ...
