Acute effects of the FIFA 11 + kids warm-up program compared with a judo-specific warm-up on explosive and functional performance in youth judo athletes: a randomized crossover study.
Article in BMC sports science, medicine & rehabilitation, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map.

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.

Abstract
backgroundThe FIFA 11 + Kids (FIFA 11+) warm-up program is effective for injury prevention and to enhance sports performance, including vertical jump (VJ), sprint, balance, and agility. However, no previous study has examined the acute effects of FIFA 11 + on performance outcomes in youth judo athletes. Therefore, this study aimed to investigate the acute effects of the FIFA 11 + warm-up program on selected physical performance parameters of youth judo athletes compared to the judo-specific warm-up (JSWU). This study employed a randomized, counterbalanced crossover design.
methodsSixteen male competitive youth judo athletes (age: 11.81 ± 1.52 years; height: 151.44 ± 11.79 cm; weight: 46.25 ± 14.42 kg; body mass index (BMI): 19.95 ± 5.50 kg/m
resultsThere were significant differences between JSWU and FIFA 11 + conditions for vertical jump (39.44 ± 7.21 vs. 41.88 ± 6.67, p = 0.008, η² = 0.40), anaerobic power (641.45 ± 211.13 vs. 665.69 ± 228.44, p = 0.010, η² = 0.38), and overhead medicine ball throw (375.19 ± 110.72 vs. 410.44 ± 114.95, p = 0.002, η² = 0.50). Significant differences were also observed in SLHD (right and left) and CHD (left), although the effect sizes were moderate to large.
conclusionsThe findings indicate that the FIFA 11 + program produced small acute improvements in selected explosive and unilateral functional performance outcomes (i.e., vertical jump, OMB throw, SLHD, and CHDLeft), while most other variables showed no significant differences compared with the judo-specific warm-up. These findings should be interpreted cautiously despite the large effect sizes, as the magnitude of improvement was practically small. The FIFA 11 + program may be a potential alternative warm-up option, though its practical application should be interpreted with caution.
trial registrationThe randomized controlled trial was retrospectively registered on 03/23/2026 at ClinicalTrials.gov, under the registration number NCT07487558 ( https://clinicaltrials.gov/study/NCT07487558 ).
