The purpose of this study was to investigate the oxygen cost of running barefoot vs. running shod on the treadmill as well as overground. 10 healthy recreational runners, 5 male and 5 female, whose mean age was 23.8±3.39 volunteered to participate in the study. Subjects participated in 4 experimental conditions: 1) barefoot on treadmill, 2) shod on treadmill, 3) barefoot overground, and 4) shod overground. For each condition, subjects ran for 6 min at 70% vVO (2)max pace while VO (2), heart…

Metabolic responses of running shod and barefoot in mid-forefoot runners.

In trained mid-forefoot runners experienced with barefoot running, there are not significant metabolic differences between shod and barefootRunning conditions.

Mechanical and physiological examination of barefoot and shod conditions in female runners.

It was found that moderate to large effect sizes suggested there were biomechanical changes that ensured between conditions that would translate into improved distance race performance while running barefoot or with minimalist footwear.

Metabolic cost of running barefoot versus shod: is lighter better?

Running barefoot offers no metabolic advantage over running in lightweight, cushioned shoes and for footwear conditions of equal mass, shod running had ∼3%-4% lower V˙O(2) and metabolic power demand than barefoot running (P < 0.05).

The effect of running barefoot and in barefoot-style footwear on running economy at two self-determined speeds.

No statistical RE benefit was found when running barefoot over FTMS or SCRS, possibly explained by a SF adaptation at higher speeds, however, practically speaking, when shoe mass is controlled for, footwear choice has a moderate but worthwhile effect on RE.

Metabolic Differences Between Shod and Barefoot Walking in Children.

At a natural walking speed, barefoot walking is more economical than shod walking at the same velocity in children, but the higher energy cost of shod Walking should be considered when evaluating the use of footwear by children.

Influence of the Shod Condition on Running Power Output: An Analysis in Recreationally Active Endurance Runners

Several studies have already analysed power output in running or the relation between VO2max and power production as factors related to running economy; however, there are no studies assessing the

Four‐week habituation to simulated barefoot running improves running economy when compared with shod running

Evaluated effects of a 4‐week familiarization to simulated barefoot running (SBR) on running economy (RE) when compared with shod running found that RE improved in the SBR condition as a result of familiarization, and became significantly lower in SBR compared withShod running.

Comparison of Running Economy Values While Wearing No Shoes, Minimal Shoes, and Normal Running Shoes

Determination of footwear for the enhancement of RE should be based on individual physical characteristics and preferences rather than a global recommendation of an economical running shoe.

Changes in sagittal plane kinematics with treadmill familiarization to barefoot running.

The results indicate that adequate familiarization should be given in future studies before gait assessment of barefoot treadmill running, as familiarization was characterized by less plantar flexion and greater knee flexion at touchdown.

Barefoot-shod running differences: shoe or mass effect?

The mechanical modifications of running showed that the main role of the shoe was to attenuate the foot-ground impact by adding damping material which may lead to a decrease of the storage and restitution of elastic energy capacity which could explain the lower net efficiency reported in shod running.

Mechanical comparison of barefoot and shod running.

Barefoot running leads to a reduction of impact peak in order to reduce the high mechanical stress occurring during repetitive steps, and this neural-mechanical adaptation could also enhance the storage and restitution of elastic energy at ankle extensors level.

Biomechanical and physiological comparison of barefoot and two shod conditions in experienced barefoot runners.

The data of this study support the assumption that changes in the foot-ground interface led to changes in running pattern in a group of experienced barefoot runners and the Fivefingers model seems to be effective in imitating the barefoot conditions while providing a small amount of protection.

Effects of shoes and foot orthotics on VO2 and selected frontal plane knee kinematics.

It appears that if orthotics do, in fact, improve running economy by improving running mechanics, the amount of improvement is negated by the additional cost of running associated with the mass of the orthotics.

Aerobic requirements of overground versus treadmill running.

It is found that the oxygen demand of level running is similar for both the treadmill (TM) and overground situations at speeds under 260 m X min-1, and that overground hill running is theoretically more costly than inclined treadmill running.

A 1% treadmill grade most accurately reflects the energetic cost of outdoor running.

Equality of the energetic cost of treadmill and outdoor running is demonstrated with the use of a 1% treadmill grade over a duration of approximately 5 min and at velocities between 2.92 and 5.0 m s-1.

Physiological characteristics of the best Eritrean runners-exceptional running economy.

The data suggest that the excellent running economy of Eritreans is associated, at least partly, with anthropometric variables and that superior running economy, rather than enhanced aerobic capacity, may be the common denominator in the success of black endurance runners of East African origin.

Validity of the Nike+ device during walking and running.

The Nike+ in-shoe device provided reasonable estimates of speed and distance during level running at the three speeds tested in this study, however, it overestimated EE during level walking and it did not detect the increased cost of inclined locomotion.
