Training Load and Performance Characteristics Across Two Consecutive Winter Altitude-Training Cycles in Women’s Quadruple Sculls Olympic Champions Preparing for the Beijing Olympics

Zhang, Yangyang, Yuan Li, Zhijun Meng, and Binghong Gao. Training load and performance characteristics across two consecutive winter altitude-training cycles in women’s quadruple sculls olympic champions preparing for the Beijing Olympics. High Alt Med Biol 00:00–00, 2026. Background: Longitudinal evidence from Olympic-level rowing squads across consecutive winter preparations is scarce. Methods: This retrospective longitudinal case series described weekly training load and pre-to-post ergometer performance in a five-rower preparation squad during linked 2006–2007 and 2007–2008 winter altitude-training cycles at ∼2,300 m; four athletes later formed the Beijing Olympic champion crew. Results: Intensity-coded volume totaled 3,911.4 and 4,127.4 km. The second cycle contained more ergometer work and a larger share of Levels V–VI rowing. Mean 2,000-m time changed by −5.98 seconds (95% confidence interval [CI]: −16.24 to 4.28; p = 0.181) and −6.00 seconds (95% CI: −10.71 to −1.29; p = 0.024), respectively. The between-cycle change-score estimate was 0.02 seconds (95% CI: −12.31 to 12.33; p = 0.997). The two lactate-test protocols were interpreted separately. All five athletes improved in the available first-cycle 6,000-m comparison. Conclusions: Across two Olympic-preparation winters, distinct training-load organizations were each accompanied by favorable sport-specific performance trajectories. These rare Olympic-champion records provide an applied benchmark for describing how volume, modality, and intensity were reorganized and reinforce the value of athlete-specific monitoring without prescribing a universal training model.
