Investigation of running foot strike technique on Achilles tendon force using ultrasound techniques and a Hill-type model
نویسندگان
چکیده
Background It is reported that 75% of long distance runners use a rearfoot strike (RFS) technique. This percentage decreases in faster runners, where the incidence of midfoot and forefoot strikers (FFS) increases [1]. It is possible that FFS better utilises the passive-elastic mechanisms of the lower limb reducing energy cost. Williams et al. [2] found runners who converted from RFS to FFS during a single training experienced increased fatigue and delayed onset muscle soreness in the calf musculature, indicating increased muscle work. This research aims to investigate the role of the Achilles tendon and triceps surae muscles in FFS versus RFS running hypothesising that the FFS will have increased Achilles tendon force.

Achilles tendon stiffness is unchanged one hour after a marathon.
Overuse-induced injuries have been proposed as a predisposing factor for Achilles tendon (AT) ruptures. If tendons can be overloaded, their mechanical properties should change during exercise. Because there data are lacking on the effects of a single bout of long-lasting exercise on AT mechanical properties, the present study measured AT stiffness before and after a marathon. AT stiffness was d...
متن کاملComparison of Achilles Tendon Loading Between Male and Female Recreational Runners
Recreational running is an activity with multiple reported health benefits for both sexes, however, chronic injuries caused by excessive and/or repetitive loading of the Achilles tendon are common. Males have been identified as being at an increased risk of suffering an injury to the Achilles tendon and as such, knowledge of differences in loading between the sexes may provide further informati...
متن کاملDoes achilles tendon cross sectional area differ after downhill, level and uphill running in trained runners?
In this study we examined how hill running affects the Achilles tendon, a common location for injuries in runners. Twenty females ran for 10 min on each of three randomly ordered grades (-6%, 0 and +6%) at speeds selected to match the metabolic rates. Achilles tendon (AT) cross-sectional area (CSA) was imaged using Doppler ultrasound and peak vertical forces were analyzed using an instrumented ...
متن کاملAchilles Tendon Repair, A Modified Technique
Background: Wound complications following open repair for acute Achilles tendon ruptures (AATR) remain the subject of significant debate. The aim of this study is to investigate the effects of covering repaired AATR using well-nourished connective tissues (paratenon and deep fascia) to avoid complications after open repair. Methods: In this case series study, open repair was performed for 3...
متن کاملAchilles and Patellar Tendon Loading during Gait Measured Using a Non-invasive Ultrasonic Technique
INTRODUCTION In vivo measurement of tendon and ligament loads remains a challenge. Forces acting on these structures during exercise have been either estimated indirectly using EMG and inverse dynamics or measured by means of invasive techniques [2]. Recently, a non-invasive technique has been proposed, based on the measurement of the velocity of ultrasound (US) propagation in the tendon [1]. I...
