Responders to Wide-Pulse, High-Frequency Neuromuscular Electrical Stimulation Show Reduced Metabolic Demand: A 31P-MRS Study in Humans. [PDF]

, 2015
Conventional (CONV) neuromuscular electrical stimulation (NMES) (i.e., short pulse duration, low frequencies) induces a higher energetic response as compared to voluntary contractions (VOL).

Effects of series elastic compliance on muscle force summation and the rate of force rise [PDF]

, 2016
Compliant tendons permit mechanically unfavourable fascicle dynamics during fixed-end contractions. The purpose of this study was to reduce the effective compliance of tendon and investigate how small reductions in active shortening affect twitch ...

Lower extremity work along with triceps surae structure and activation is altered with jumping after Achilles tendon repair

Journal of Orthopaedic Research, 2019
Achilles tendon rupture leads to long term plantar flexor deficits. The purpose of this study was to describe changes in jumping biomechanics along with triceps surae structure and activation in individuals after Achilles repair.

Isometric training at longer muscle–tendon complex lengths: A potential countermeasure to impaired neuro‐muscle–tendon function during space travel

Experimental Physiology, EarlyView.
Abstract Manned space exploration to distant destinations, including Mars, continues to be an aspiration of humankind. Space travel does, however, present many challenges to the body, amongst which adaptation to microgravity is perhaps the largest. For instance, both short and long manned spaceflight missions have shown substantial deleterious effects ...

Postural control of sway dynamics on an unstable surface reduces similarity in activation patterns of synergistic lower leg muscles

Frontiers in Sports and Active Living
IntroductionDiversity of activation patterns within synergistic muscles can be important for stability control in challenging conditions. This study investigates the similarity of activation patterns within the triceps surae and quadriceps femoris ...

Microgravity‐induced changes in skeletal muscle and possible countermeasures: What we can learn from bed rest and human space studies

Experimental Physiology, EarlyView.
Abstract Despite exercise countermeasures to sustain health and performance in spaceflight, complete maintenance of muscle mass and functions in microgravity is still not possible for most astronauts. The principal cause of the limited effectiveness of existing exercise countermeasures is the difficulty in achieving full loading forces in space.

Infrared thermography applied to lower limb muscles in elite soccer players with functional ankle equinus and non-equinus condition [PDF]

PeerJ, 2017
Gastrocnemius-soleus equinus (GSE) is a foot-ankle complaint in which the extensibility of the gastrocnemius (G) and soleus muscles (triceps surae) and ankle are limited to a dorsiflexion beyond a neutral ankle position.

Elastic properties in triceps surae : a comparison between cyclists and runners [PDF]

, 2013
Tendons have different degrees of elasticity, stiffness, so that energy can be stored and released. In the Achilles tendon (AT) an extension of 5 % has been measured at maximum isometric muscle work.

Improvement of isometric dorsiflexion protocol for assessment of tibialis anterior muscle [PDF]

, 2015
It is important to accurately estimate the electromyogram (EMG)/force relationship of triceps surae (TS) muscle for detecting strength deficit of tibalis anterior (TA) muscle.

Reliability of a device measuring triceps surae muscle fatigability [PDF]

British Journal of Sports Medicine, 2004
Objective:To examine the test–retest reliability of a protocol using an apparatus designed to standardise the standing heel rise test for the triceps surae muscle.Subjects:40 healthy subjects volunteered to test short and medium term test–retest reliability (group SM, median age 24 years), and a convenience sample of 38 subjects with a history of ...
