Pronation ras, travail de renforcement ok. Manipulation cuboid efficace dans tendinite achille. Pronation RAS mais VLR. Perte alignement du genou. Plus de technologie doit être intégrer pour s'approcher de la course pieds nus. Amélioration performance pour minimalist, chaussure légère (<440g/paire) et un peu de resistance de semlle. Plus la semelles est molle, plus il y a de tension dans le genou et la cheville. Diminution de 13% de la consommation energetic durant la course en MF.

Email: amcoughl@svsu.edu (No relationships reported) Minimal footwear running shows shorter stride lengths (higher stride frequencies) vs. traditionally heel-elevated shoes (Lieberman, 2012).
PURPOSE: To examine differences in running economy between treadmill trials among experienced (EM) and non-experienced minimalist (NM) shoe runners wearing minimalist and traditional footwear. METHODS: Nineteen experienced runners (running ≥3 days/wk, ≥30 min/run, ≥3 mo) completed the study (age 22 ± 4 y, height 174.5 ± 11.3 cm, weight 74.8 ± 15.7 kg, BMI 24.3 ± 2.3 kg/m2). RESULTS: Step rates for all stages were greater in MF (p<0.05), specifically Stage 4 (MF = 163.7 ± 10.1, TF = 161.1 ± 9.5 steps/2min, p=0.05). Pas de changement ds la VO2 pour des coureur expérimenté/mais plus rapide.

PURPOSE: The purpose of this study is to examine the effect of minimal running shoes (MRS) on peak oxygen consumption (peakVO2) and 5 km running performance. METHODS: Twelve moderately trained subjects (10 male, 2 female), all habitual shod runners, participated in a series of 5 maximal trials 7 days apart.
RESULTS: Mean (±sd) MRS and shod running peakVO2 values 54.68 ± 3.74 and 54.04 ± 4.44 ml.min-1.kg-1 respectively was not different (p=0.532). Chaussure avec semelle épaisse augment instabilité pied.

Email: mercerm@unlv.nevada.edu (No relationships reported) Running economy is defined as the oxygen cost for running at a given submaximal speed. PURPOSE: To determine the effect of wearing extreme cushioning shoes on running economy at different speeds and inclines. METHODS: Subjects (n=10, age 28.7±6.4 yr, weight: 67.8±10.4 kg, height: 1.72±0.09 m) were fitted with a pair of neutral running shoes (Addidas Prene) and a pair of extreme cushioning shoes (Hoka Bondi 4).
RESULTS: VO2 was not influenced by the interaction of speed and shoe (p=0.496). CONCLUSIONS: It seems that the cushioning of the shoe (extreme vs. regular) play no role in the influence of running economy.
