Case Report: Jet lag and travel fatigue effects on performance in a world-class paralympic shot-putter after eastward long-haul transmeridian travel.

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
Introduction: This case report aimed to examine the effects of long-haul eastward transmeridian travel on neuromuscular performance, subjective well-being, and internal training load in a World-class female Paralympic shot-putter preparing for the Paris 2024 Paralympic Games. Methods: An F54-class athlete was monitored for 21 days surrounding a flight from Chile to France (eastward, six time zones). Daily assessments included handgrip strength (HGS), shot-put throwing distance, subjective well-being, and session rating of perceived exertion (s-RPE). Descriptive statistics and Spearman's correlation were used to explore relationships between performance and physiological/subjective variables. Results: Transient reductions in HGS occurred for 3-4 days post-travel, followed by daily fluctuations. Jet lag and fatigue scores were elevated during the first post-travel days but showed progressive improvement, returning to near-baseline levels by approximately two weeks before competition. Throwing performance showed a moderate positive correlation with left-hand HGS ( Conclusion: Long-haul transmeridian travel was associated with transient neuromuscular and perceptual disturbances in a world-class Paralympic athlete. HGS and s-RPE emerged as practical and responsive markers of travel-induced fatigue and performance readiness during the 21-day period surrounding international travel. These findings highlight the need for individualized monitoring strategies during the travel adaptation period in elite Paralympic sport contexts.
