1 · What the graph read from it

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.

2 · The registry

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

backgroundPost-competition refeeding in physique athletes is poorly understood. We aimed to characterize physiological and psychological changes in natural physique athletes across contest preparation and a 12-week recovery period, and to explore the influence of post-competition refeeding strategies.

methodsNineteen natural physique athletes (8 male, 11 female) were assessed at baseline (~21 weeks pre-competition; T0), 1-2 weeks pre-final competition (Tpre), and 2, 6, and 12 weeks post-competition (T2, T3, T4). Measures included body composition (DXA), resting metabolic rate (RMR), thyroid hormones (FSH, FT3, FT4), absolute strength (IMTP peak force), and psychometric questionnaires (POMS, ASSQ, EDE-QS).

resultsBody weight decreased from T0 to Tpre (-7.1 kg [-8.3, -5.9]), driven primarily by FM loss (-5.8 [-6.8, -4.8]), with modest FFM loss (-1.7 [-2.6, -0.9]). Both FM and FFM rebounded predominantly within the first 6 weeks post-competition (Tpre→T3: +3.4 [2.3, 4.4] and +2.7 [1.8, 3.6], respectively). By T4, FM was not clearly different from T0 (-0.8 [-1.8, 0.3], while FFM exceeded T0 (+1.6 [0.7, 2.5]). RMR·FFM

conclusionsContest preparation was accompanied by fat loss, thyroid hormone suppression, and modest reductions in RMR, with recovery characterized by early increases in RMR and tissue restoration following competition. Larger post-competition increases in energy intake were associated with faster recovery of adjusted RMR, although FM regain occurred concurrently. Post-competition recovery should be treated as an active, structured phase, with refeeding individualized to athlete goals and psychological readiness and guided by multi-system monitoring rather than RMR alone. Athletes and coaches should plan ahead for this phase, with structured increases in food intake, realistic expectations around fat gain, and avoidance of unnecessarily prolonged restriction that may delay physiological recovery.
