About this study
Official title: Changes of Biomechanical Parameters During Race Simulation Rowing - The Effect of (In)Stability of the Simulator
Rowing simulators are frequently used by rowers, when on-water training is impossible or limited. While such devices are highly valuable to maintain rowers' fitness, a concern was raised about extensive simulator usage. It was postulated that it could lead to technique alterations due to different biomechanical properties compared to on-water rowing. Slide-based rowing simulators were designed to better simulate on-water conditions.
The main aim of the study was to compare the differences in various kinematic and kinetic parameters during a short (20 s) all-out rowing bout and during a 2000-m simulated race, to get a better insight into how different rowing simulator designs affect biomechanics of rowing.

Three different rowing simulators were used in this study: (1) a standard stable/fixed rowing simulator, (2) a slides based rowing simulator, i.e. horizontal plane unstable, and (3) a tilt board based rowing simulator; i.e. frontal plane unstable.
The investigators hypothesised that rowing on different simulators will elicit different biomechanics, including forces, power output, arm and seat movement velocity and amplitude.
Each of the participants completed the tests in all three interventions on separate sessions; random order of interventions. The three sessions took place 7-10 days apart. During each session, the participants completed the all-out 20-s trial first, then the simulated 2000-m race. The aforementioned biomechanical parameters were tracked throughout the trials to be compared between interventions later.
Read the detailed description
The measurements will take place at University of Primorska (Koper, Slovenia) and the subjects will be recruited in close collaboration with Rowing Club Piran. Crossover study design will be used. Each participant will be asked to come for three visits that will be scheduled 7-10 days apart. Prior to measurements onset, the whole protocol will be explained to the participant.
Measurement procedure:
- 15-min warm-up
- 20-s maximal (all-out) rowing
- 5-minute break
- 2000-m simulated race
After both trials, blood lactate will be measured. Blood sample will be taken at the the earlobe by a qualified medical personnel.
Maximal performance test: The participant will perform a 20-s interval with maximal effort. The main aim of the measurement is to record the maximal exerted force and power. The custom adapted device (Concept 2 Rowing Simulator) records the positions (seat and handle) and force (legs push and handle pull), which enables for further calculations of segmental and common kinematics and dynamics parameters.
Race simulation: the participant will complete the 2000-m simulated race and will be instructed to aim for the best results. The same measurements as in the maximal performance test will be performed. Wireless heart rate monitor will be used to record the heart frequency throughout the trial.
Equipment:
The custom adapted rowing simulator (Concept 2) allows for the measurements of stoke forces and consequently power outputs, seat and handle velocity, and seat and handle amplitudes. Signals will be transferred to central unit, amplified and converted, and stored on a personal computer.
The interventions (i.e. the studied rowing conditions) will be as follows:
- a standard stable/fixed rowing simulator,
- a slides based rowing simulator, i.e. horizontal plane unstable, and
- a tilt board based rowing simulator; i.e. frontal plane unstable.

Clinical summary

Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 18 Aug 2017. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Rowing performance (time frame: Three sessions, with randomized order of ergometers (7-10 days apart)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Aug 2017.
