“…Considering that human anthropometry is subject to a circadian rhythm (eg, larger body length in the morning than in the evening), 18 it is hypothesized that the foot is exposed to physical load throughout the day that might have an effect on the MLA. This is supported by Fourchet et al, 19 who showed changes in measured pedobarographic foot characteristics following high-intensity running.…”

BackgroundAlthough pedobarographic measurement is increasingly used for clinical and research purposes, relatively few published studies have investigated normative data. This study examined pedobarographic findings in young healthy adults with regard to sex-related differences and correlations among measurement indices.MethodsTwenty young healthy adults (mean age, 22.4 years; standard deviation, 1.2 years; and 10 males and 10 females) were included. Weight bearing anteroposterior (AP) and lateral foot radiographs were taken, and dynamic pedobarographic data during treadmill walking and maximum ankle dorsiflexion were obtained. AP talo-first metatarsal angle, naviculocuboid overlap, lateral talo-first metatarsal angle, and plantar soft tissue thickness were measured on foot radiographs. Pedobarographic data including peak pressure and pressure-time integral were measured on five plantar segments: medial forefoot (MFF), lateral forefoot (LFF), medial midfoot (MMF), lateral midfoot (LMF), and heel.ResultsMale and female subjects significantly differed in body mass index (BMI, p < 0.001), AP talo-first metatarsal angle (p = 0.018), soft tissue thickness under the metatarsal head (p = 0.040) and calcaneal tuberosity (p < 0.001), maximum dorsiflexion during stance phase (p = 0.041), peak pressure on the MFF (p = 0.005) and LFF (p = 0.004), and pressure-time integral on the MFF (p = 0.018) and heel (p = 0.001). BMI was significantly correlated with soft tissue thickness under the metatarsal head (r = 0.521, p = 0.018) and calcaneal tuberosity (r = 0.585, p = 0.007), peak pressure on the MFF (r = 0.601, p = 0.005) and LFF (r = 0.487, p = 0.029), pressure-time integral on the heel (r = 0.552, p = 0.012), and total pressure-time integral (r = 0.755, p < 0.001). Maximum dorsiflexion demonstrated significant negative correlations with pressure-time integral on the MFF (r = −0.595, p = 0.007) and total pressure-time integral (r = −0.492, p = 0.032). Pressure-time integral varus/valgus index was significantly correlated with pressuretime integral forefoot/heel index (r = 0.472, p = 0.036).ConclusionsSex-related differences in pedobarographic examination were observed, which could provide useful information in setting appropriate treatment goals and obtaining appropriate control data. The effects of subtalar motion in distributing plantar pressure should be investigated in a future study.

“…Fourchet et al showed that the total contact area of the foot would increase after fatigue due to increase in the contact area of the midfoot [27]. Nagel et al in their study on 200 subjects participating in a marathon race investigated the parameters of plantar pressure measurements.…”

This study aimed to compare the effects of fatigue due to overground and treadmill running on the plantar pressure distribution pattern. Methods: Twelve novice athletes (Mean±SD age=26.0±2.5 y, Mean±SD weight: 52.0±3.0 kg, Mean±SD height: 159.0±5.0 cm), without sports injuries over the past year, were selected. Overground and treadmill running created fatigue in the samples. Peak plantar pressure distribution, Center of Pressure, contact area, and impulse the samples were recorded using a footscan (Footscan Version 7 Gait 2 nd generation software) pressure system during running before and after the fatigue protocol and analyzed with repeated measures ANOVA in SPSS v. 18. Results: Peak plantar pressure on the second to fifth toe , the fourth and fifth metatarsal bones, and medial part of the heel significantly increased. The shift in the Center of Pressure of the foot was non-significant in all stages. The contact area at the second metatarsal and midfoot area shifted only before the fatigue protocol on overground running. Impulse at the second to fifth toe, first to fifth metatarsal, significantly increased in the ground running. Conclusion: The results showed that fatigue due to treadmill running has different effects compared to fatigue due to overground running.

High-Intensity Running and Plantar-Flexor Fatigability and Plantar-Pressure Distribution in Adolescent Runners

Abstract: Fatigue resistance in the plantar flexors declined after a high-intensity running bout performed by adolescent male distance runners. This phenomenon was associated with increased loading under the medial arch in the fatigued state but without any excessive pronation.
