Effect of New Zealand Blackcurrant Extract on Force Steadiness of the Quadriceps Femoris Muscle during Sustained Submaximal Isometric Contraction. [PDF]
J Funct Morphol Kinesiol, 2022 Intake of anthocyanin-rich New Zealand blackcurrant (NZBC) can alter physiological responses that enhance exercise performance. In two studies, we examined the effects of NZBC extract on force steadiness during a sustained submaximal isometric ...

Heavy mental task has no effect on sex differences in muscle fatigability during moderate-intensity isometric contraction. [PDF]
Sci RepIn some physical activities with simultaneous mental task, we can observe greater muscle fatigability in women than in men. These differences are evident in various muscle groups, especially during low-intensity isometric or intermittent isometric ...

The EEG-Based Fusion Entropy-Featured Identification of Isometric Contraction Forces under the Same Action. [PDF]
Sensors (Basel)This study explores the important role of assessing force levels in accurately controlling upper limb movements in human–computer interfaces. It uses a new method that combines entropy to improve the recognition of force levels.

Unilateral isometric contraction induces REDD1 and suppresses insulin-stimulated mTORC1 and protein synthesis in non-contracted muscle of male mice. [PDF]
Physiol RepSkeletal muscle hypertrophy is promoted by mechanical loading and is associated with activation of mTORC1 signaling. While REDD1, a stress‐responsive inhibitor of mTORC1, is typically downregulated in contracting muscle, we previously reported that ...

Heart Frequency Patterns Due to 30% and 50% Maximal Isometric Contraction (MIC) in Adolescents [PDF]
E3S Web of Conferences, 2023 We often do isometric contractions. Isometric contractions cause cardiovascular responses, including changes in heart rate. The aim of this study was to examine the effect of isometric contraction intensity equivalent to 30% MIC and 50% MIC with handgrip

Study on the development of the motor quality force by using the isometric contraction process [PDF]
Annals of the “Ştefan cel Mare” University: Physical Education and Sport Section - The Science and Art of Movement, 2022 The work started from a desire to develop the motor quality of strength through isometric contraction in high school students. There are data in the literature confirming the benefits of these exercises, but it must be kept in mind that an intense ...

Isometric and Anisometric Contraction Relationships with Surface Electromyography [PDF]
2021 43rd Annual International Conference of the IEEE Engineering in Medicine & Biology Society (EMBC), 2021 The isometric contraction is the most investigated muscle contraction, however most tasks in daily life involve anisometric contractions. Most hand prostheses studies [1] use sEMG features to directly relate the exerted force as a means of intuitive control.
