Overload of the lower limbs of firefighters as a result of external conditions.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundIt is known that a firefighter's uniform with all equipment will significantly increase the load on the lower limbs during landing. The higher landing height will also increase ground reaction forces. However, it is unknown what effect the firefighters' experience (job seniority) will have on the load. Moreover, age-related changes in neuromuscular control, balance, and muscular strength may alter the way external loads are managed, potentially increasing susceptibility to overload.
objectiveThe present study aimed to evaluate the overload of the musculoskeletal system resulting from changing external conditions.
methodsThe main study involved 171 firefighters divided into three age categories: up to 25 years (In=83), up to 44 years (IIn=38) and over 44 years (IIIn=50). The subjects performed three landing on to the force platforms from two heights (0.5 m; 1.0 m) and in two types of clothes: sport and fire protection. For the evaluation of lower limb overloads, the value of generated ground reaction force relative to body weight (GRF/BW) of the participant and time of force affecting the locomotor system (amortization time) were evaluated (t > 1 BW).
resultsIncreasing the landing height from 0.5 m to 1 m resulted in a significant (p < 0.001) increase in ground reaction forces. Furthermore, younger participants generated significantly greater forces (p < 0.001). Performing the landing in protective clothing also resulted in increased load (p < 0.001). Furthermore, older firefighters had a longer (p < 0.01) cushioning time at both landing heights and in both clothing. CONCLUSION AND APPLICATION: These results suggest that younger or less experienced firefighters may employ suboptimal landing strategies, increasing their injury risk.
