Individualized Training to Improve Aerobic Capacity and 2,000 m Rowing Performance in Youth Rowers

Chile44 participantsStarted 2026-06

Plain-language summary

The goal of this randomized clinical trial is to learn whether an individualized rowing training program based on ventilatory thresholds can improve aerobic capacity and 2,000 m rowing performance in youth rowers from Valdivia, Chile. The study will include male and female rowers aged 14 to 18 years who train regularly at Club de Remeros Arturo Prat. The main questions it aims to answer are: Does ventilatory threshold-based individualized training improve maximal oxygen uptake compared with the usual club training program? Does ventilatory threshold-based individualized training improve 2,000 m rowing ergometer performance compared with the usual club training program? Researchers will compare an individualized training group with a usual training group to see if prescribing exercise intensity based on each rower's ventilatory thresholds produces greater improvements in aerobic capacity, rowing performance, and related physiological measures. Participants will: Complete baseline and post-intervention assessments, including a cardiopulmonary exercise test on a rowing ergometer, blood lactate measurements during an incremental rowing test, a 2,000 m rowing ergometer test, body composition assessment, and respiratory muscle strength testing. Be randomly assigned to either an individualized training group or a usual training group. Complete a 12-week rowing training program. Use heart rate monitors during study training sessions so that training intensity, adherence, and safety can be monitored. Report any discomfort, injuries, or adverse events during the study. The individualized training group will train according to heart rate zones derived from each participant's ventilatory thresholds measured at baseline. The usual training group will continue the club's regular training program. The study will also explore individual variability in training response and the proportion of participants who respond or do not respond to each training approach.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion Criteria: * Active membership in Club de Remeros Arturo Prat of Valdivia. * Age between 14 and 18 years. * Systematic rowing training of at least 3 sessions per week under technical supervision. * Participation in federated competitions or internal selection processes. * Medical clearance for intense physical exercise issued by a treating physician or competent institution, such as a pre-participation medical evaluation. Exclusion Criteria: * History of uncontrolled cardiovascular, respiratory, or metabolic disease that contraindicates intense exercise, such as structural heart disease, clinically significant arrhythmias, or uncontrolled asthma. * Acute or chronic musculoskeletal injury that prevents completion of the training program or study assessments. * Use of medications that may substantially modify the physiological response to exercise, such as beta-blockers, or declared history of doping. * Acute illness at the time of assessment, including fever, infection, or respiratory symptoms. * Cognitive, language, or behavioral difficulties that prevent understanding instructions or complying with the study protocol. * Simultaneous participation in another exercise intervention study.

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?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
