The study will include male and female rowers aged 14 to 18 years who train regularly at Club de Remeros Arturo Prat.\n\nThe main questions it aims to answer are:\n\nDoes 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?\n\nResearchers 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.\n\nParticipants will:\n\nComplete 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.\n\nBe randomly assigned to either an individualized training group or a usual training group.\n\nComplete a 12-week rowing training program. Use heart rate monitors during study training sessions so that training intensity, adherence, and safety can be monitored.\n\nReport any discomfort, injuries, or adverse events during the study.\n\nThe 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.
