What makes females walk at comparable speeds to males? Physical, physiological, or biomechanical factors.
Article in Journal of physiological anthropology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundAlthough males typically have longer limbs and greater muscle mass than females, previous studies have reported no significant sex differences in self-selected walking speed. This suggests that females may adopt alternative biomechanical strategies to compensate for their anatomical disadvantages. However, the specific mechanisms that enable females to achieve a walking speed comparable to males remain unclear.
methodsOne hundred and fifty-one young adults (76F,75M) performed a 3-min barefoot walking at their self-selected walking speed on a 10-m walkway. During walking, spatiotemporal gait parameters, vertical ground reaction forces, and foot and ankle joint kinematics were recorded. Anthropometric measurements and body composition were also obtained to assess physical capacity. Walking speed was compared between males and females, and contributing factors to walking speed were analyzed.
resultsSelf-selected walking speed was not significantly different between sexes. However, when normalized by leg length, females exhibited significantly longer stride lengths and faster walking speeds than males (p < 0.05). Females also demonstrated greater ankle joint range of motion and walked with significantly greater ankle plantarflexion at toe-off, which likely contributed to increased forefoot pushing force. Additionally, females exhibited longer normalized stride lengths and faster stride times, resulting in faster normalized walking speeds compared to males.
conclusionThe findings suggest that females compensate for relatively shorter limb lengths and lower muscle mass by relying more on distal joint flexibility and passively generated push-off power, particularly at the ankle. Females may also adjust stride length and stride time to achieve walking speeds comparable to males despite anatomical differences. Interventions aimed at modifying push-off strategies may enhance walking efficiency and could inform the development of targeted, sex-specific gait training programs.
