What is muscle thickness? 


Best insight from top research papers

Muscle thickness (MT) is a crucial indicator of muscle activity during contraction, essential for musculoskeletal studies in sports science and rehabilitation engineering. It can be measured using innovative technologies like muscle thickness sensors that differentiate between muscle contraction and relaxation, minimizing signal noise from adjacent structures. Studies have shown that MT, measured via ultrasound, correlates well with muscle anatomical cross-sectional area (ACSA) and volume changes following resistance training, highlighting its reliability as a marker for muscle characteristics. Automated tracking methods based on optical flow algorithms offer efficient and accurate measurements of muscle thickness during contractions, surpassing manual approaches in terms of repeatability and objectivity. Utilizing ultrasonic images, advanced methods have been developed to enhance the accuracy and efficiency of real-time muscle thickness measurements.

How do muscles grow big and stronger after training?
5 answers
Muscles grow bigger and stronger after training primarily through adaptations in muscle protein synthesis (MyoPS) and ribosome biogenesis. Resistance training stimulates MyoPS, leading to muscle repair and hypertrophy. The initial MyoPS response to exercise is focused on repairing muscle damage, while later responses drive muscle hypertrophy. Ribosome biogenesis plays a crucial role in increasing muscle mass post-training, with total RNA abundance reflecting ribosomal density and influencing muscle growth. Additionally, the mechanistic target of rapamycin complex 1 (MTORC1) pathway is vital in coordinating protein synthesis and muscle hypertrophy. These processes, along with neural adaptations and signaling pathways, contribute to muscle mass and strength gains following strength training. Ultimately, the combination of increased MyoPS, ribosome biogenesis, and MTORC1 activation leads to muscle growth and enhanced strength post-training.
How is progressive muscle relaxation done?
5 answers

How does asthma effect muscle mass?
5 answers
Asthma can significantly impact muscle mass in patients. Studies have shown that patients with asthma may experience low appendicular skeletal muscle mass index (ASMI), with frequencies ranging from 16% to 19%. Low skeletal muscle mass has been associated with worse pulmonary function, exercise capacity, and quadriceps muscle function in asthma patients, particularly in those with normal weight. Additionally, asthma patients with uncontrolled symptoms tend to have increased fat mass and decreased muscle mass compared to controlled asthma patients or healthy individuals. This decrease in muscle mass can lead to reduced functional capacity and physical activity levels in asthmatic patients, potentially due to a more sedentary lifestyle. Furthermore, studies have indicated that bronchial muscle hyperplasia, characterized by increased muscle cell volume and number, is present in asthmatics compared to control subjects.

How does the use of different planting densities impact the quality and potency of traditional Chinese medicinal materials?
6 answers
The impact of planting densities on the quality and potency of traditional Chinese medicinal materials (TCMM) is a nuanced subject that involves understanding the ecological and biological dynamics of plant growth and secondary metabolite production. Research indicates that suitable planting densities can significantly influence the yield and quality of medicinal plants, as seen in the cultivation of G. uralensis, where medium-density planting was found to suppress rhizome development while enhancing the yield and quality of taproots, including the concentration of medicinally active components such as glycyrrhizic acid, glycyrrhizin, and flavonoids. Similarly, for Panax notoginseng, a moderate planting density was beneficial for balancing primary and secondary metabolism, leading to high biomass and ginsenoside accumulation, which are critical for its medicinal potency. The quality and efficacy of TCMM are also influenced by ecological variations and ecotype differentiation, which are the results of long-term ecological adaptation and natural selection. These variations contribute to the unique eco-diversity of TCMM, characterized by multi-local and multi-Daodi TCM, thereby affecting the quality and potency of the medicinal materials. Furthermore, the quality control of TCMM must adhere to biogenetic polymorphic regularity, emphasizing the importance of genetic, pharmacogenetic, and molecular biology principles in understanding the natural pharmacodynamic mechanism of Chinese materia medica. This approach underlines the significance of considering biogenetic diversity and ecological conditions in the cultivation and quality assessment of TCMM. In summary, the use of different planting densities directly impacts the quality and potency of TCMM by influencing the plants' growth conditions, secondary metabolite production, and ecological adaptation. These findings underscore the importance of adopting scientifically informed cultivation practices to optimize the medicinal value of TCMM, taking into account the complex interplay between genetic diversity, ecological conditions, and cultivation density.
