“…The greater AVLR of the MSR group may be problematic because these runners also were wearing minimalist shoes, which reduce plantar contact area and increase calcaneal contact pressure. 43,44 The vertical ground reaction force curves of all MSR and TSR runners in this study contained impact peaks. No MSA vertical ground reaction force curves contained impact peaks.…”

Context:The injury incidence rate among runners is approximately 50%. Some individuals have advocated using an anterior-foot-strike pattern to reduce ground reaction forces and injury rates that they attribute to a rear-foot-strike pattern. The proportion of minimalist shoe wearers who adopt an anterior-foot-strike pattern remains unclear.Objective: To evaluate the accuracy of self-reported footstrike patterns, compare negative ankle-and knee-joint angular work among runners using different foot-strike patterns and wearing traditional or minimalist shoes, and describe average vertical-loading rates.Design: Descriptive laboratory study. Setting: Research laboratory. Patients or Other Participants: A total of 60 healthy volunteers (37 men, 23 women; age ¼ 34.9 6 8.9 years, height ¼ 1.74 6 0.08 m, mass ¼ 70.9 6 13.4 kg) with more than 6 months of experience wearing traditional or minimalist shoes were instructed to classify their foot-strike patterns.Intervention(s): Participants ran in their preferred shoes on an instrumented treadmill with 3-dimensional motion capture.Main Outcome Measure(s): Self-reported foot-strike patterns were compared with 2-dimensional video assessments.Runners were classified into 3 groups based on video assessment: traditional-shoe rear-foot strikers (TSR; n ¼ 22), minimalist-shoe anterior-foot strikers (MSA; n ¼ 21), and minimalist-shoe rear-foot strikers (MSR; n ¼ 17). Ankle and knee negative angular work and average vertical-loading rates during stance phase were compared among groups.Results: Only 41 (68.3%) runners reported foot-strike patterns that agreed with the video assessment (j ¼ 0.42, P , .001). The TSR runners demonstrated greater ankle-dorsiflexion and knee-extension negative work than MSA and MSR runners (P , .05). The MSA (P , .001) and MSR (P ¼ .01) runners demonstrated greater ankle plantar-flexion negative work than TSR runners. The MSR runners demonstrated a greater average vertical-loading rate than MSA and TSR runners (P , .001).Conclusions: Runners often cannot report their foot-strike patterns accurately and may not automatically adopt an anterior-foot-strike pattern after transitioning to minimalist running shoes.Key Words: barefoot running, ground reaction forces, negative work, loading rate Key PointsAccuracy of self-reported foot-strike patterns for runners wearing minimalist running shoes was poor. A cohort of runners who wore minimalist shoes for at least 6 months demonstrated a rear-foot-strike pattern and potentially injurious ground reaction force rates of loading. Runners using a rear-foot-strike pattern and wearing traditional shoes demonstrated more overall knee excursion, greater knee-extension negative work, and greater ankle-dorsiflexion negative work than runners wearing minimalist shoes, regardless of foot-strike pattern.

“…5,[7][8][9][10]22,26 When examining a side-cut task, the medial portion of the foot experiences more loading than the lateral portions of the foot. 5,10 The results of this study are similar to those that have been reported previously with the largest loads being seen beneath the medial border of the foot.…”

“…Therefore, it was noteworthy to find a substantial increase (i.e., ?5.60 mm on average) in COP path length for the non-MOCP users at &ovulation compared to menstruation (in agreement with H 2 ). Intuitively, an increase in COP path length may be attributed to an increase in mid-foot contact area due to a more flat-footed posture (Queen et al 2010). Given the protocol-induced consistency in ground contact time, a longer COP path at &ovulation is thought to have contributed to the concomitant increase in COP velocity (i.e., ?18.60 mm s -1 on average) given that foot movements associated with absorption and propulsion during the hopping task would need to occur at a faster rate.…”

Estrogen-induced effects on the neuro-mechanics of hopping in humans

Estrogen receptors in skeletal muscle suggest a tissue-based mechanism for influencing neuromuscular control. This has important physiological implications for both eumenorrheic women with fluctuating estrogen levels and those with constant and attenuated estrogen levels, i.e., women using the monophasic oral contraceptive pill (MOCP). This study examined the effects of endogenous plasma estrogen levels on leg stiffness (K (LEG)) and foot center of pressure (COP) during hopping. Nineteen females (Age = 28.0 ± 4.2 years, Ht = 1.67 ± 0.07 m, Mass = 61.6 ± 6.8 kg) who had been using the MOCP for at least 12 months together with 19 matched, female, non-MOCP users (Age = 31.9 ± 7.3 years, Ht = 1.63 ± 0.05 m, Mass = 62.5 ± 5.9 kg) participated. Non-MOCP users were tested at the time of lowest (menstruation) and highest (≈ ovulation) estrogen whilst MOCP users were tested at Day 1 and Day 14 of their cycle. At each test session, K (LEG) (N m(-1) kg(-1)) and foot COP path length (mm) and path velocity (mm s(-1)) were determined from ground reaction force data as participants hopped at 2.2 Hz on a force plate. Statistical analysis revealed no significant (p < 0.05) differences for K (LEG). In contrast, significantly higher COP path length (30%) and COP path velocity (25%) were identified at ≈ ovulation compared to menstruation in the non-MOCP users. Whilst there was no evidence of an estrogen-induced effect on K (LEG); significantly elevated estrogen at ≈ ovulation presumably increased extensibility of connective tissue and/or diminished neuromuscular control. Consistent lower limb dynamics of MOCP users demands less reliance on acutely modified neuromuscular control strategies during dynamic tasks and may explain the lower rate of lower limb musculoskeletal injuries in this population compared to non-MOCP users.
