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

objectiveThis study aimed to compare the intervention effects of the FIFA11 + and Harmoknee warm-up programs on the coordination and change-of-direction abilities (COD) of college soccer players.

methodsA randomized parallel-group experimental design was adopted. Fifty-three male university soccer players (mean age 21.6 ± 0.9 years) were randomly assigned to the FIFA 11 + group (N = 18), the Harmoknee group (N = 17), or the control group (N = 18). All three groups underwent an 8-week intervention with two training sessions per week. Coordination was assessed using the Haller cycle test (HCT), while COD ability was evaluated through the 5-0-5 test, Illinois agility test (IAT), T-test, and Slalom test.

resultsAfter the 8-week intervention, the FIFA11 + group demonstrated a significant main effect of time across all measured variables (P < 0.01). The Harmoknee group also showed significant improvements in all variables except the Slalom test (P < 0.05). The control group exhibited significant improvements only in the HCT (P < 0.01) and the IAT (P < 0.05). Between-group comparisons revealed that the FIFA11 + group performed significantly better than the control group in the post-test measurements of the HCT (P < 0.01, Cohen’s d = 0.942), the 5-0-5 test (P < 0.05, Cohen’s d = 1.125), the IAT (P < 0.01, Cohen’s d = 1.082), and the Slalom test (P < 0.01, Cohen’s d = 1.079). The Harmoknee group performed significantly better than the control group only in the 5-0-5 test (P < 0.05, Cohen’s d = 0.925) and the IAT (P < 0.05, Cohen’s d = 0.401).

conclusionBoth the 8-week FIFA11 + and Harmoknee warm-up programs can enhance the coordination and change-of-direction abilities of college soccer players, albeit to varying degrees. The FIFA11 + program demonstrated superior efficacy in improving change-of-direction abilities, particularly as measured by the 5-0-5, IAT, and T-tests. It also exhibited positive improvement trends and post-test advantages in coordination ability and the Slalom test. Therefore, in training contexts where the development of multiple COD abilities in soccer players is a priority, the more systematically structured FIFA11 + warm-up program may be recommended.
