Effects of Novel Inverted Rocker Orthoses for First Metatarsophalangeal Joint on Gastrocnemius Muscle Electromyographic Activity during Running: A Cross-Sectional Pilot Study

open access: yesSensors, 2020
Background: The mobility of the first metatarsophalangeal joint (I MPTJ) has been related to the proper windlass mechanism and the triceps surae during the heel-off phase of running gait; the orthopedic treatment of the I MPTJ restriction has been made ...

Evidence of a Uniform Muscle-Tendon Unit Adaptation in Healthy Elite Track and Field Jumpers: A Cross Sectional Investigation

open access: yesFrontiers in Physiology, 2019
Different adaptive responses to mechanical loading between muscle and tendon can lead to non-uniform biomechanical properties within the muscle-tendon unit.

Do triceps surae muscle dynamics govern non-uniform Achilles tendon deformations? [PDF]

open access: yesPeerJ, 2018
The human Achilles tendon (AT) consists of sub-tendons arising from the gastrocnemius and soleus muscles that exhibit non-uniform tissue displacements thought to facilitate some independent actuation.

Repetitive hops induce postactivation potentiation in triceps surae as well as an increase in the jump height of subsequent maximal drop jumps. [PDF]

open access: yesPLoS ONE, 2013
Postactivation potentiation (PAP) has been defined as the increase in twitch torque after a conditioning contraction. The present study aimed to investigate the effectiveness of hops as conditioning contractions to induce PAP and increase performance in ...

Considerations for Improving Triceps Surae Flexibility

open access: yes, 2015
Triceps surae flexibility exercises are routinely prescribed as a component of lower extremity fitness and rehabilitation programs. Flexibility deficits, addressed without consideration of hindfoot position, may be associated with and perpetuate foot and

Effects of fatigue are more pronounced on the uninjured side during single‐limb jumps 2 years after an acute Achilles tendon rupture

open access: yesKnee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Achilles tendon rupture (ATR) is a serious lower limb injury that may result in persistent deficits in strength and endurance of the calf muscles. Compensatory mechanisms at proximal joints are known, but the effects of fatigue are less studied.

Myofascial trigger point therapy for triceps surae dysfunction: Acaseseries

open access: yes, 2013
Aims: The main aim of the case series was to inform further experimental research to determine the effectiveness of myofascial trigger point (MTrP) therapy for the treatment of triceps surae dysfunction.

Habitual foot strike pattern does not affect simulated Triceps Surae muscle metabolic energy consumption during running

open access: yes, 2019
Foot strike pattern affects ankle joint work and Triceps Surae muscle-tendon dynamics during running. Whether these changes in muscle-tendon dynamics also affect Triceps Surae muscle energy consumption is still unknown.

Risk Factors for Exercise‐Associated Muscle Cramps: A Systematic Review With Meta‐Analysis

open access: yesMuscle &Nerve, EarlyView.
ABSTRACT Introduction/Aims Exercise‐associated muscle cramps (EAMC) are common in athletic populations and are frequently cited as a factor limiting performance. Despite extensive investigation, uncertainty remains regarding the risk factors associated with EAMC.

Neuromechanical Adaptation to Walking With Electromechanical Ankle Exoskeletons Under Proportional Myoelectric Control

open access: yesIEEE Open Journal of Engineering in Medicine and Biology, 2023
Objective: To determine if robotic ankle exoskeleton users decrease triceps surae muscle activity when using proportional myoelectric control, we studied healthy young participants walking with commercially available electromechanical ankle exoskeletons (
