Effects of Unstable Core Training on Sport Performance Among Kayakers
A study testing static unstable core training (SUCT) for the experimental group in people with Athletic Performance and Resistance Training, run by Gao Jianxin at 1 site in China.
Trial summary
A randomized controlled trial was conducted, recruiting 24 eligible kayakers aged 14-22 years from the Jiangxi training base, China. Participants were randomly assigned to the SUCT group and the DUCT group. Both groups completed a 12-week unstable core training program consisting of 1-hour sessions, 3 times/week.

About this study
Official title: Effects of Static and Dynamic Unstable Core Training on Balance Ability, Trunk Muscle Strength and Paddling Performance Among Young Male Flatwater Sprint Kayakers
A randomized controlled trial was conducted, recruiting 24 eligible kayakers aged 14-22 years from the Jiangxi training base, China. Participants were randomly assigned to the SUCT group and the DUCT group. Both groups completed a 12-week unstable core training program consisting of 1-hour sessions, 3 times/week. Balance ability was assessed using the flamingo balance test and star excursion balance test. Trunk muscle strength was assessed using the abdomen, back, side bridge tests, sit-up, back extension, and trunk rotation tests. Paddling performance was evaluated using the average stroke power and stroke rate for the men's K-1 200m land ergometer sprint tests.
- Conditions
- Athletic Performance, Resistance Training, Kayaking
- Being tested
- static unstable core training (SUCT) for the experimental group, dynamic unstable core training (DUCT) for the control group

Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
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.

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?
Flamingo balance test score (time frame: Baseline (before intervention), immediately after 12-week training intervention). The study lists 8 primary outcomes in all. 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 3 Aug 2026.
