“…Recent studies has shown that injured runners present higher values of LR [46,47]. Thus, since this VGRF variable is highly associated with some running injuries [46,48–51], BF running could characterize a initially harmful situation to habitual SH runners [1,9,20,35,36,49]. As expected, EMG signal followed the same behavior observed for external load.…”

Short-term effects of barefoot and simulated barefoot running have been widely discussed in recent years. Consequences of adopting barefoot running for a long period, including as a training approach, still remain unknown. The present study evaluated the influence of 16 weeks of progressive barefoot running training on impact force and muscle activation in habitual shod runners. Six habitual shod runners (3 men and 3 women, 29.5 ± 7.3 years) were tested barefoot (BF) and shod (SH), before and after 16 weeks of progressive barefoot running training. Tests consisted of running on instrumented treadmill at 9 km/h, for 10 minutes in each experimental condition. Nine data acquisitions (10 s) of vertical ground reaction force (VGRF) and electromyographic (EMG) signal were conducted in each experimental condition for each test. BF training was effective to alter VGRF and EMG parameters of running in habitual shod runners, regardless of footwear condition (SH or BF). The magnitude of first peak of VGRF (Fy1) and the impulse of the first 50 ms decreased after training for BF and SH (p<0.01). The activation reduced from PRE to POST training for four muscles in BF running (p<0.001), whereas only muscle gastrocnemius lateralis decreased significantly its activation (p<0.01) in SH running. A 16-week progressive barefoot running training seems to be an effective training strategy to reduce impact force, improve shock attenuation and to decrease muscle activation intensity, not only in BF running, but also in SH running, although BF condition seems to be more influenced by BF training.

“…One common approach to achieve this has been through reducing musculoskeletal loading. Recent prospective evidence indicates that biomechanical variables related to impact are lower in runners who have not sustained musculoskeletal injuries, and this supports data from numerous retrospective studies that have demonstrated greater loading parameters in injured runners [10]. In the past decade, lower body positive pressure treadmills (LBPPTs) have emerged as a novel tool to reduce loading on the musculoskeletal system during walking and running.…”

The current literature suggests that LBPPTs are effective in allowing individuals to achieve a given metabolic stimulus with reduced musculoskeletal loading. However, LBPPTs not only reduce impact but also change neuromuscular activation and biomechanics in a complex manner. Thus, clinicians must account for the specific biomechanical and physiological alterations induced by LBPPTs when designing training programs and rehabilitation protocols.

“…Hence, a great number of these runners are not able to return to running because of such injuries . Patellofemoral pain (PFP), iliotibial band syndrome (ITBS), medial tibial stress syndrome, and Achilles tendinopathy are instances of such common pains in runners . To cut down the occurrence of these chronic injuries, risk factors call for specialized identification in injury preventive programs.…”

This study was aimed to compare the effects of 8‐week conditioning training (CT) programs with and without feedback on lower limbs' biomechanics and injury incidence in free‐injury male runners and assess their effectiveness across a 1‐year observation. A total of 49 healthy male runners were randomly assigned to one of three groups of CT (n = 16), CT with feedback (n = 17), and placebo (n = 16) group. Kinematic and kinetic measurements were conducted at pre‐intervention, 8 weeks post‐intervention, and 1‐year follow‐up stage. Injury incidence was also measured at pre‐intervention and follow‐up stage. As a result, significant improvement was found in within‐group differences in CT and CT with feedback groups. Moreover, significant difference in CT with feedback group was observed in the kinetic outcome improvement after 8 weeks as compared to CT group. On the other side, there were no significant differences between the CT and CT with feedback groups in kinematic outcomes. However, the percentage of changes in kinematic outcomes were higher in CT with feedback group than those in the CT group. No significant change was observed in the placebo group in all the variables. There was comparative between‐group difference between CT with feedback group and the placebo one, favoring the former group. At 1‐year follow‐up, the injury incidence was reduced by 32% for CT group, 64.6% for CT with feedback group, and 15.5% for placebo. Thus, the CT with feedback was effective in improving biomechanics and reducing injury incidence. Improvements were generally maintained through 1 year, indicating potential for long‐term changes. This study demonstrates the applicability of using feedback with CT to enhance safer movement patterns in runners and may subsequently help prevent or reduce injury risks.
