Impact of 30-minute and 90-minute Naps on Aerobic and Anaerobic Intermittent Performance in Collegiate Soccer Players.
Article in Nature and science of sleep, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled 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.
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
Purpose: This study aims to investigate the effects of 30-minute and 90-minute naps on collegiate soccer players' aerobic and anaerobic performance following a normal night of sleep, and to compare the performance differences between the two nap durations. Patients and Methods: A total of 25 male collegiate soccer players (age: 20 ± 1 years, height: 180.4 ± 5.6 cm, weight: 72.1 ± 4.2 kg, BMI: 22.1 ± 2.2 kg·m⁻²) participated in the RAST and 30-15. Intermittent fitness test (IFT) under three conditions: no nap (N0), 30-minute nap (N30), and 90-minute nap (N90). Results: Post-nap assessments showed significant improvements in peak power per weight (p = 0.007, η² = 0.13), minimum power per weight (p < 0.001, η² = 0.25), and average power per weight (p < 0.001, η² = 0.28) in the RAST test, with no notable differences between the N30 and N90 groups. Additionally, the fatigue index (FI) in the N90 group significantly decreased compared to N0 (p = 0.005, d = 0.86). Both N30 and N90 groups exhibited higher VIFT values than the N0 group (p < 0.001, η² = 0.23). However, no significant changes were noted in average heart rate (p = 0.198) or perceived exertion (RPE) (p = 0.376) during the 30-15 IFT after napping. Conclusion: Napping effectively enhances the aerobic and anaerobic performance of collegiate soccer players following a normal night of sleep. Implementing strategic napping may be beneficial for athletes seeking to optimize their performance before training or competition.
