Frequency-dependent coexistence of muscle fatigue and potentiation assessed by concentric isotonic contractions in human plantar flexors.

Publication Type:Academic Journal

Source(s):Journal of applied physiology (Bethesda, Md. : 1985) [J Appl Physiol (1985)] 2022 Aug 01; Vol. 133 (2), pp. 490-505. Date of Electronic Publication: 2022 Jul 07.

Abstract:The purpose was to investigate whether postactivation potentiation (PAP) mitigates power (i.e., torque × angular velocity) loss during dynamic fatiguing contractions and subsequent recovery by enhancing either muscle torque or angular velocity in human...

Kinematics of individual muscle units in natural contractions measured in vivo using ultrafast ultrasound.

Publication Type:Academic Journal

Source(s):Journal of neural engineering [J Neural Eng] 2022 Sep 06; Vol. 19 (5). Date of Electronic Publication: 2022 Sep 06.

Abstract:Objective. The study of human neuromechanical control at the motor unit (MU) level has predominantly focussed on electrical activity and force generation, whilst the link between these, i.e. the muscle deformation, has not been widely studied. To addre...

Far-infrared-emitting fabric improves neuromuscular performance of knee extensor.

Publication Type:Academic Journal

Source(s):Lasers in medical science [Lasers Med Sci] 2022 Jul; Vol. 37 (5), pp. 2527-2536. Date of Electronic Publication: 2022 Feb 10.

Abstract:The aim of this study was to verify if exposure to the far-IR emitted by fabric (FIR) is able to improve the neuromuscular performance of the knee extensors of resistance-trained males regardless of changes of the temperature. It is a crossover, random...

Canine Smooth Muscle Contraction Model.

Publication Type:Academic Journal

Source(s):Annual International Conference of the IEEE Engineering in Medicine and Biology Society. IEEE Engineering in Medicine and Biology Society. Annual International Conference [Annu Int Conf IEEE Eng Med Biol Soc] 2022 Jul; Vol. 2022, pp. 4958-4961.

Abstract:Smooth muscle is found extensively in the human body, including in blood vessels, airways, the gastrointestinal tract, and the urinary bladder. Although the contractile proteins of smooth muscle are very similar to those of striated muscle, smooth musc...

Dynamic 3D Ultrasound Imaging of the Tibialis Anterior Muscle.

Publication Type:Academic Journal

Source(s):Annual International Conference of the IEEE Engineering in Medicine and Biology Society. IEEE Engineering in Medicine and Biology Society. Annual International Conference [Annu Int Conf IEEE Eng Med Biol Soc] 2022 Jul; Vol. 2022, pp. 3899-3902.

Abstract:Skeletal muscle volume has been mainly investigated under static conditions, i.e. isometric contractions. The aim of our study is to use ultrasound imaging to determine muscle deformation during movement. We used a custom-designed scanning rig to obtai...

Potential role of passively increased muscle temperature on contractile function.

Publication Type:Academic Journal

Source(s):European journal of applied physiology [Eur J Appl Physiol] 2022 Oct; Vol. 122 (10), pp. 2153-2162. Date of Electronic Publication: 2022 Jun 30.

Abstract:Declines in muscle force, power, and contractile function can be observed in older adults, clinical populations, inactive individuals, and injured athletes. Passive heating exposure (e.g., hot baths, sauna, or heated garments) has been used for health ...

The rate of force development scaling factor: a review of underlying factors, assessment methods and potential for practical applications.

Publication Type:Academic Journal

Source(s):European journal of applied physiology [Eur J Appl Physiol] 2022 Apr; Vol. 122 (4), pp. 861-873. Date of Electronic Publication: 2022 Jan 19.

Abstract:When humans perform isometric ballistic contractions of different intensities, a strong linear relationship is observed between peak force and peak rate of force development. The slope of this relationship, termed the rate of force development scaling ...

Residual force enhancement is affected more by quadriceps muscle length than stretch amplitude.

Publication Type:Academic Journal

Source(s):ELife [Elife] 2022 May 17; Vol. 11. Date of Electronic Publication: 2022 May 17.

Abstract:Little is known about how muscle length affects residual force enhancement (rFE) in humans. We therefore investigated rFE at short, long, and very long muscle lengths within the human quadriceps and patellar tendon (PT) using conventional dynamometry w...

Distribution of innervation zone and muscle fiber conduction velocity in the biceps brachii muscle.

Publication Type:Academic Journal

Source(s):Journal of electromyography and kinesiology : official journal of the International Society of Electrophysiological Kinesiology [J Electromyogr Kinesiol] 2022 Apr; Vol. 63, pp. 102637. Date of Electronic Publication: 2022 Feb 04.

Abstract:The spatial distributions of muscle innervation zone (IZ) and muscle fiber conduction velocity (CV) were examined in nine healthy young male participants. High-density surface electromyography (EMG) was collected from the biceps brachii muscle when sub...
