Background—A study was undertaken to determine whether swimming training improved aerobic capacity, exercise induced bronchoconstriction (EIB), and bronchial responsiveness to inhaled histamine in children with asthma. Methods—Eight children with mild or moderate asthma participated in swimming training every day for six weeks. The intensity of training was individually determined and set at 12...

The purpose of this study was to evaluate the validity of the predicted V02 max from the Astrand-Ryhming nomogram, using the cycle ergometer as the sole exercise mode and following the recommended submaximal test protocol. In addition, two sets of age correction factors were compared for accuracy. Using the Astrand age correction factors, the SEE of the predicted V02 max for the 40 male subject...

The purpose of this study was to test the concurrent validity of the ICBE compared to the Monark(®) cycle ergometer by indirect dynamic calibration. 42 men were randomly submitted to 2 maximal stress tests with increments of 50 W at 2-min intervals. One test was performed on the Monark(®) bicycle (834/E) and the other on the ICBE. Cardiovascular, perceived exertion and hemodynamic responses wer...

The aim of this study was to verify if it is possible to determine the lactate minimum test (LMT) by saliva sodium (Na+), potassium (K+) and lactate (LAC) concentrations in arm ergometer and cycle ergometers. Eight male international-level table tennis players participated in this study. To induce increases of lactate concentration in both ergometers, 30 seconds maximal tests were used with max...

In order to individualize the intensity of an aerobic training program on different ergometers in healthy elderly subjects using a single test of muscular exercise, we analysed cardiorespiratory responses in 8 men (65.7 +/- 4.5 yrs) and 10 women (63.3 +/- 4.8 yrs). The heart rate corresponding to the ventilatory threshold was defined as individualised exercise intensity. All subjects carried ou...

Despite the prevalence of shoulder injury in kayakers, limited published research examining associated upper limb kinematics and recruitment patterns exists. Altered muscle recruitment patterns on-ergometer vs. on-water kayaking were recently reported, however, mechanisms underlying changes remain to be elucidated. The current study assessed the effect of ergometer recoil tension on upper limb ...

BACKGROUND Magnetic resonance imaging (MRI) is an important tool for cardiac research, and it is frequently used for resting cardiac assessments. However, research into non-pharmacological stress cardiac evaluation is limited. METHODS We aimed to design a portable and relatively inexpensive MRI cycle ergometer capable of continuously measuring pedalling workload while patients exercise to mai...
