Data from the DCD clinical trial - ClinicalTrials.gov Identifier: NCT02904980
(University of Exeter, 2018-11-06)This is the dataset used for the Slowinski et al. (2018) article "Gaze training supports self-organization of movement coordination in children with developmental coordination disorder" submitted to Scientific Reports. -
Perceptual and Cardiorespiratory Responses to High-Intensity Interval Exercise in Adolescents: Does Work Intensity Matter?
(University of Uludag, 2019)Objectives: High-intensity interval exercise (HIIE) may not elicit prominent unpleasant feelings even with elevated perceived exertion and physiological stress in adolescents. However, the influence of different HIIE work ... -
Qualitative and quantitative change in the kinematics of learning a non-dominant overarm throw
(Elsevier, 2018-10-26)This study investigated changes in non-dominant overarm throw technique over practice from the perspective of three distinct though potentially complementary approaches to motor skill acquisition. Ten participants (mean ± SD ... -
Limit cycle dynamics of the gymnastics longswing
(Elsevier, 2017-12-30)The purpose of the study was to examine the macroscopic dynamics of the longswing through a limit cycle analysis of the motion of the center of mass (CM) as a function of skill level. One elite international, five gymnasts ... -
Differential strain patterns of the human Achilles tendon determined in vivo with freehand three-dimensional ultrasound imaging
(Company of Biologists, 2013-01-30)The human Achilles tendon (AT) has often been considered to act as a single elastic structure in series with the muscles of the triceps surae. As such it has been commonly modelled as a Hookean spring of uniform stiffness. ... -
Corrigendum: Linking the mechanics and energetics of hopping with elastic ankle exoskeletons
(American Physiological Society, 2013-07-15)Corrigendum to: Farris DJ, Sawicki GS. Linking the mechanics and energetics of hopping with elastic ankle exoskeletons. J Appl Physiol 113: , 2012. First published October 11, 2012; doi:10.1152/japplphysiol.00802.2012.—The ... -
Elastic ankle exoskeletons reduce soleus muscle force but not work in human hopping
(American Physiological Society, 2013-09-01)Inspired by elastic energy storage and return in tendons of human leg muscle-tendon units (MTU), exoskeletons often place a spring in parallel with an MTU to assist the MTU. However, this might perturb the normally efficient ... -
Achilles tendon (3D): Do the mechanical properties of tendon change in response to exercise?

Elastic ankle muscle-tendon interactions are adjusted to produce acceleration during walking in humans
(Company of Biologists, 2017-09-27)Humans and other cursorial mammals have distal leg muscles with high in-series compliance that aid locomotor economy. This muscle-tendon design is considered sub-optimal for injecting net positive mechanical work. However, ... -
Lower limb biomechanics and muscle function

Individual limb mechanical analysis of gait following stroke
(Elsevier, 2015-02-07)The step-to-step transition of walking requires significant mechanical and metabolic energy to redirect the center of mass. Inter-limb mechanical asymmetries during the step-to-step transition may increase overall energy ... -
Revisiting the mechanics and energetics of walking in individuals with chronic hemiparesis following stroke: from individual limbs to lower limb joints
(BMC, 2015-02-27)BACKGROUND: Previous reports of the mechanics and energetics of post-stroke hemiparetic walking have either not combined estimates of mechanical and metabolic energy or computed external mechanical work based on the limited ... -
The variable relationship between sarcomere number and fascicle length when measured in vivo in human lower limb muscle

The Influence of Foot-Strike Technique on the Neuromechanical Function of the Foot
(Lippincott, Williams & Wilkins / American College of Sports Medicine (ACSM), 2018-01-01)PURPOSE: The aim of this study was to investigate the influence of foot-strike technique on longitudinal arch mechanics and intrinsic foot muscle function during running. METHODS: Thirteen healthy participants ran barefoot ... -
The effect of cadence on the muscle-tendon mechanics of the gastrocnemius muscle during walking
(Wiley, 2016-02-16)Humans naturally select a cadence that minimizes metabolic cost at a constant walking velocity. The aim of this study was to examine the effects of cadence on the medial gastrocnemius (MG) muscle and tendon interaction, ... -
UltraTrack: Software for semi-automated tracking of muscle fascicles in sequences of B-mode ultrasound images
(Elsevier, 2016-04-02)Background: Dynamic measurements of human muscle fascicle length from sequences of B-mode ultrasound images have become increasingly prevalent in biomedical research. Manual digitisation of these images is time consuming ... -
Effect of muscle force during stretch on eccentric contraction-induced muscle damage

Emulating constant acceleration locomotion mechanics on a treadmill
(Elsevier, 2016-02-10)Locomotion on an accelerating treadmill belt is not dynamically similar to overground acceleration. The purpose of this study was to test if providing an external force to compensate for inertial forces during locomotion ... -
The effect of muscle-tendon unit vs. fascicle analyses on vastus lateralis force-generating capacity during constant power output cycling with variable cadence
(American Physiological Society, 2018-04-16)The maximum force-generating capacity of a muscle is dependent on the lengths and velocities of its contractile apparatus. Muscle-tendon unit (MTU) length changes can be estimated from joint kinematics; however, contractile ...
