Eccentric Cycling Exercise on Hemodynamic and Hemorheologic Properties
Taiwan60 participantsStarted 2019-11-11
Plain-language summary
The effects of an eccentric endurance training on central and peripheral hemodynamic adaptations and erythrocyte rheology during maximal exercise remained to be unexplored. The current study examined the contribution of rheological functions and/or hemodynamic adaptation to changes in oxygen consumption (VO2) following the matched-power output eccentric (ECT) or concentric cycling training (CCT).
Method: A total of 39 sedentary males were randomly assigned into either CCT (n=13) or ECT (n=13) for 30 min a day, 5 days a week for 6 weeks at 60% of maximal workload or to a CTL (control group, n = 13). A graded exercise test (GXT) was performed before and after the intervention. Central and microvascular adaptations were evaluated using thoracic impedance and near-infrared spectroscopy (NIRS), respectively. Rheological characteristics was determined by an ektacytometer.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
