“…The latter are appreciated for their many advantages: they are very thin and easy to wear contrary to insoles with wedges, they do not need any battery and they are customizable. Previous studies showed that thin plantar inserts can induce neuromuscular responses [ 4 , 5 ], variations of plantar pressure distribution [ 6 ], of the medio-lateral position of the Center of Pressure (CoP) [ 7 ], or of foot eversion during walking [ 8 ]. Yet, the effects of such thin stimulations on balance in quiet stance have been little studied so far.…”

The purpose of this study was to assess properties of vergence and saccade eye movements as well as posture in quiet stance, and the effects of thin plantar inserts upon postural and oculomotor control. The performances of 36 young healthy subjects were recorded by a force platform and an eye tracker in three testing conditions: without plantar stimulation, with a 3 millimetre-thick plantar insert, either a Medial or a Lateral Arch Support (MAS / LAS). The results showed a decrease of the Surface and Variance of Speed and a more posterior position of the CoP with either stimulation compared with the control condition. The fractal analysis showed a decrease with MAS. Wavelet analysis in the time-frequency domain revealed an increase in the Cancelling Time of the low frequency band with MAS. These results suggest a better stability for a lower energy cost. Concerning eye movements, the inserts influenced only vergence (not saccades): MAS caused an increase of the phasic amplitude of divergence, and conversely a decrease of the tonic amplitude. In contrast, LAS caused an increase of the tonic amplitude of convergence. Thus, MAS renders divergence less visually driven, while LAS renders convergence more visually driven. We conclude that the CNS uses the podal signal for both postural and vergence control via specific mechanisms. Plantar inserts have an influence upon posture and vergence movements in a different way according to the part of the foot sole being stimulated. These results can be useful to clinicians interested in foot or eye.

“…Moreover, stimulation of the plantar arch would induce the individual to perceive his own center of mass as moving towards the foot, thus inducing him to compensate through moving the center of pressure in the opposite direction (Janin and Dupui 2009).…”

“…It reflects the general distribution of pressure in the plantar. Here we take middle of the back heel as zero point, the line from zero point to head of the 2 nd metatarsal phalangeal joint as vertical axis, front as positive direction of the Y-axis, vertical with which the line passing zero point we take as X-axis, and the inside of foot as positive direction of the X-axis [14]. Foot length and width is normalized to reduce impact of foot shape.…”

By using Rs-scan insole pressure test system, this article measures and analyses teenagers' gait and foot pressure in mid-long distance running and conducts quantitative experiment to mid-long distance running by selecting master, level 1&2 teenage runners to form the experiment group and ordinary university students to form the control group. Firstly, it briefly introduces the development of research on running gait biology and foot pressure test system. By dividing feet pressure into various areas and using effective experimental method, it designs and measures such parameters as gait cycle & phase, Center of Pressure (COP) track, Pressure-Time Integral (PTI), Partition Peak Pressure (PP), etc. Finally, it reaches relevant conclusions through comparative analysis of measurement data. This research provides theoretic support and data basis for research on foot pressure distribution, mechanism of force in different phases of sport and prevention of sports injury. KEY WORDS: mid-long distance running, rs-scan, gait, foot pressure distribution characteristics, contrast experiment CARACTERISTICILE MERSULUI ŞI ALE DISTRIBUŢIEI PRESIUNII PLANTARE LA ADOLESCENŢI ÎN TIMPUL ALERGĂRII PE DISTANŢĂ MEDIE ŞI LUNGĂ REZUMAT. Acest articol măsoară şi analizează mersul şi presiunea piciorului la adolescenţi în timpul alergării pe distanţă medie şi lungă utilizând sistemul de testare a presiunii branţului Rs-scan şi efectuând un experiment cantitativ de alergare pe distanţă medie şi lungă prin selectarea unor adolescenţi la nivel 1, 2 şi expert, care au format grupul de experiment şi a unor studenţi obişnuiţi pentru a forma grupul martor. În primul rând, se prezintă pe scurt evoluţia cercetărilor privind biomecanica alergării şi sistemul de testare a presiunii piciorului. Prin împărţirea piciorului în diferite zone de presiune şi prin utilizarea unei metode experimentale eficiente, se proiectează şi măsoară parametri cum ar fi ciclul şi faza de mers, traiectoria centrului de presiune (COP), integrala presiune-timp (PTI), presiunea maximă pe zone (PP) etc. În cele din urmă, se ajunge la concluzii relevante prin analiza comparativă a datelor măsurate. Această cercetare oferă sprijin teoretic şi o bază de date pentru cercetarea privind distribuţia presiunii piciorului, mecanismul forţei în diferite faze ale sportului şi prevenirea rănilor sportive.
