The learning effect in repeated Yo-Yo intermittent recovery tests in adults with different levels of physical fitness.

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
This pilot study investigates the learning effect in repeated trials of the Yo-Yo Intermittent Recovery Test in adults with different levels of physical fitness. Twenty physically active (PAS) and non-physically active subjects (NAS) participated in the study (age 19.9 ± 1.6 years, height 174.5 ± 8.1 cm, body mass 66.5 ± 8.2 kg, and BMI 21.8 ± 1.6 kg/m²). They repeatedly performed the Yo-Yo Intermittent Recovery Test (Level 1) once a week until performance plateaued. Maximal heart rate was analyzed in three one-minute intervals after the test was completed. PAS completed 3.1 ± 1.28 and NAS completed 2.7 ± 0.15 trials. Performance level significantly improved from the initial to the final trial in both PAS (from 14.5 ± 1.1 to 15.2 ± 1.1, p = .006) and NAS (from 13.0 ± 1.0 to 13.5 ± 0.9, p = .008). Similarly, the distance covered significantly increased in both the PAS (from 588.5 ± 317.4 m to 748.7 ± 373.4 m, p = .001) and the NAS (from 360.0 ± 175.9 m to 432.0 ± 188.4 m, p = .003). Maximal oxygen uptake also significantly increased in the PAS (from 41.6 ± 1.8 ml/kg/min to 43.3 ± 2.4 ml/kg/min, p = .005) as well as in the NAS (from 39.5 ± 1.5 ml/kg/min to 40.1 ± 1.6 ml/kg/min, p = .003). However, there were no significant changes in maximal heart rate between the first and last trials in either group. These findings indicate a significant learning effect in the Yo-Yo Intermittent Recovery Test (Level 1) over 3 trials, regardless of the subjects' level of physical fitness. However, this may bias the results, and therefore, practice trials are recommended before testing.
