The effects of walking, running, and shoe size on foot volumetrics
Physical Therapy in Sport, 2003
Objectives. The objective of this study was to investigate the effects of walking and running on foot volumetrics, and its relationship between measured foot size and preferred shoe size. Design. This study was a single-group, repeated measures design. Twenty-eight physical therapy students participated in the testing. Methods. Following 10 min of supine rest, a pre-exercise volumetric measurement of the right leg was obtained. Shoe size and foot length measurements were taken. Subjects were randomly assigned to a treatment condition (walking or running). The treadmill speed was set at a comfortable pace for each participant during exercise. Foot volume measurements were taken after the exercise. Subjects returned the next week to participate in the second condition. Results. Paired t-tests were used to compare differences in outcome variables. Significant increases in fluid volumes were noted within groups after walking (2%) and running (3%) and between groups in the post-walk and post-run values (1.7%). A weak positive correlation was noted between changes in volume during running and the measured difference between foot size and shoe size (r ¼ 0:39; p ¼ 0:038). Conclusions. Treadmill running for 10 min may lead to significantly greater foot volume compared to treadmill walking for the same period. Results also demonstrate that the greater the measured difference between shoe size and foot size, the greater the foot volume after running. q
Acute Effects of Long Distance Running on Plantar Foot Pressure Distribution
2022
Twenty-six healthy men and women participated in this study in which 14 were long distance runners and remaining were control subjects. Following the initial assessment of foot pressure distribution, the runners were asked to complete the regular training program. Immediately after the run, foot pressure distribution was again assessed using the Zebris FDM-Treadmill. The parameters were analysed and compared with the pre-training data. The same parameters were also assessed for the control group at rest. Paired t-test was used to compare the foot pressure distribution before and after the run. Independent t-test was used to compare the same parameters between runners and control group. No significant changes were observed in runners post run whereas the control group showed significant changes in the foot pressure distribution of right forefoot and backfoot when compared to long distance runners at rest. The findings of the study suggest that the foot pressure distribution is not affected acutely after the long distance running. The future studies could analyse the plantar pressure measurement throughout the training programs to detect the time and nature of the deviations linked to long distance run, which would help in injury prevention.

Background: Different foot postures are associated with alterations in foot function, kinetics and the subsequent occurrence of injury. Little is known about changes in foot posture following prolonged weightbearing exercise. This study aimed to identify changes in foot posture after running a half marathon. Methods: Foot posture was measured using the Foot Posture Index (FPI-6) and navicular height in thirty volunteer participants before and after running a half marathon. FPI-6 scores were converted to Rasch logit values and means compared for these and navicular height using an ANOVA. Results: There was a 5 mm drop in navicular height in both feet when measured after the half marathon (P < 0.05). The FPI-6 showed a side x time interaction with an increase in score indicating a more 'pronated' position in the left foot of + 2 [Rasch value + 1.7] but no change in the right foot (+ 0.4 [+ 0.76]) following the half marathon. Conclusion: The apparent differences between the FPI-6 and navicular height on the right foot may be because the FPI-6 takes soft tissue contour changes into consideration whilst the navicular height focuses on skeletal changes. The changes in foot posture towards a more pronated position may have implications for foot function, and therefore risk of injury; shoe fit and comfort and also the effect of therapeutic orthoses worn during prolonged running.
It is possible that running training for many years in athletics affects athletes' running patterns and sole structure. The main aim of this study is to examine the effect of maximal force applied to the floor area and contact area of the athletes with related to mid-distance training for athletics. 18 male athletes who represent Turkey on the International area and another 25 male volunteers who form the control group from the participants of the study. The sole pressure measurement of the participants was performed through the use of EMED-SF (Novel H, Munich, Germany) plantar pressure analysis system (pedobarographic analysis). In the study, significant differences were found in heel medial, heel lateral, foot middle, 2nd, 3rd and 4th metatars heads and left foot 3rd, 4th, 5th finger in the contact area values of the right and left foot averages. Besides, significant differences were found in heel medial, middle part of feet, 2nd and 3rd metatars heads and 2nd, 3rd, 4th and 5th fingers in maximal force values. Athletes have pressed on sole of the feet more as a result of long-term training and as a consequence this pressure caused a change of the soles contact area and maximal strength. Also it can be said that they have used forefront part of soles more actively during running and walking.

Background: An association between fluid intake and changes in volumes of the upper and lower limb has been described in 100-km ultra-marathoners. The purpose of the present study was (i) to investigate the association between fluid intake and a potential development of peripheral oedemas leading to an increase of the feet volume in 100-km ultra-marathoners and (ii) to evaluate a possible association between the changes in plasma sodium concentration ([Na + ]) and changes in feet volume. Methods: In seventy-six 100-km ultra-marathoners, body mass, plasma [Na + ], haematocrit and urine specific gravity were determined pre-and post-race. Fluid intake and the changes of volume of the feet were measured where the changes of volume of the feet were estimated using plethysmography.

The aim of this research is to analyze the impact of long-term trainings of middle distance runners in athletics to the distribution of pressure on the soles by comparing the peak pressure which belongs to the areas of the soles of healthy individuals, average maximal pressure, and pressure-time integral pedobarographic parameters; with elite male middle distance runners.18 elite middle distance runners (age average; 20.25±3.6) who have no feet complaint and who have taken part in Turkish National Championships of Athletics; and as the control group, 25 voluntary males (age average; 26.10±2.40) have participated in this research. The sole pressure measurement of the volunteers was made by using EMED-SF (Novel H, Munich, Germany) plantar pressure analysis system (pedobarographic analysis). The data used SPSS 18.0 package program. According to the measurement of elite middle distance runners’ and control group’s 11 measuring range in both right and left foot, and with regard to the co...
