Cumulative endpoint and reconstructed 500-m energy-system contributions from individualized pacing-matched trials in 2000-m rowing ergometry.
Article in Frontiers in physiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Objective: To evaluate the accuracy with which 500-, 1000-, and 1500-m endpoint trials reproduced each rower's individualized 2000-m pacing template, estimate cumulative energy-system contributions at 500, 1000, 1500, and 2000 m, and reconstruct contributions across four successive 500-m segments. Methods: Twelve trained male provincial-team rowers completed a 2000-m all-out rowing-ergometer reference trial to establish individualized cumulative time, mean power, and mean stroke-rate targets, followed by pacing-matched 500-, 1000-, and 1500-m endpoint trials. Pacing-replication accuracy was evaluated using achieved-minus-target bias, MAE, MAPE, concordance, and Bland-Altman limits of agreement. Energy-system contributions were estimated indirectly using the PCr-La-O Results: At 500, 1000, and 1500 m, time MAE was 0.050, 0.092, and 1.258 s; power MAE was 0.667, 0.917, and 5.083 W; and stroke-rate MAE was 0.750, 0.396, and 0.359 spm, respectively. Corresponding MAPE values were 0.053-0.431% for time, 0.157-1.339% for power, and 1.239-2.483% for stroke rate. No stable group-level systematic bias was detected after Holm adjustment, although statistical equivalence was not tested. Reconstruction showed a higher estimated phosphagen contribution during 0-500 m, glycolytic contribution concentrated mainly within the first 1000 m, and a higher aerobic contribution after the opening segment. No robust segmental difference in total estimated contribution was concluded. Conclusions: Individualized known-endpoint trials can closely reproduce a rower's 2000-m pacing template while providing endpoint-specific post-exercise inputs for cumulative indirect energy-system estimation. Within-rower reconstruction offers a transparent way to describe successive 500-m energetic patterns alongside actual kinematics, but these reconstructed segments should not be interpreted as direct physiological measurements of continuous race phases or as a validated training prescription.
