Single muscle fiber contractile properties with run training
… properties of individual slow and fast myofibers in response to various training periods throughout a collegiate cross-country season in male runners. Muscle biopsies were obtained from the gastrocnemius of five runners at three time points during the season; after a summer aerobic training …

Control of Skeletal Muscle Fiber Types by Calcium Signaling Pathways
… programs of gene expression in skeletal muscles, thereby establishing a high degree of metabolic and physiological specialization among myofiber subtypes. Previous studies have demonstrated that calcineurin activity is required to maintain slow myofiber identity. I am interested in …

Investigating a non-invasive method for determining muscle fiber composition
… aims to explore a new method for analysis of muscle fiber type, using data collected from weightlifts on a leg press. A dynamic muscle model is developed, which utilizes the Descherevskii kinetic theory in combination with a muscle "matrix" model to predict net muscle contraction forces and …

Examining the Influence of Muscle Fiber Type on Protein Turnover Signaling in Growing Pigs
Postnatal skeletal muscle growth occurs through myonuclear accretion and high protein turnover rate. While fiber type composition of the muscle could affect protein turnover rate, less is known about how fiber type influences the regulation of protein synthesis and degradation signaling pathways. …

Effects of Ractopamine and Muscle Fiber Number on Swine Growth Performance, Carcass Traits, and Meat Quality
… and if its response is influenced by varying muscle fiber number and birth weight. The swine industry is under increasing pressure to maximize efficiency, profitability, and lean meat production. Advances in nutrition, genetics, and general livestock management have enabled producers to …

The effect of insulin treatment and exercise modality on skeletal muscle fiber size in streptozotocin-induced type 1 diabetic rats
… to have several negative effects on skeletal muscle mass, a condition known as diabetic myopathy. One of these effects is the atrophy of the glycolytic muscle fibers. However, the role of intensity of insulin treatment and exercise modality in attenuating this loss in fiber cross-sectional …

Association of Masseter Muscle PITX2, ENPP1 and ESR1 Expression, Muscle Fiber Type, Temporomandibular Joint Disorders and Subclassifications of Craniofacial Asymmetry
… associations with functional properties in muscle and bone. The objectives of this study are to investigate how PITX2, ENPP1 and ESR1 gene expression associates with four subclassifications of craniofacial asymmetry, temporomandibular disorders and fiber type differences compared between …

Effects of Lubabegron supplementation on carcass traits, muscle fiber type, proteome profile and meat quality attributes of finished feedlot steers
… (MS), adjusted fat thickness (aFT), longissimus muscle area (LMA), kidney pelvic and heart fat percentage (KPH), and USDA calculated yield grade (YG) were evaluated for all carcasses (N = 2160). No dose x feeding duration (FD) interaction (P > 0.05) was present for any of the characteristics …

The Influence of Age and Sampling Depth on Muscle Fiber Type Percentages and Enzyme Activities of Equine Middle Gluteal Muscle
The effects of age and sampling depth on histochemical and biochemical properties of equine gluteus medius were examined.

The fiber type specific response of single muscle fiber contractile performance to endurance and resistance exercise training in healthy, sedentary adults
It is well documented that human skeletal muscle is highly responsive to exercise training. However, the impact of endurance and resistance exercise training on single muscle fiber (SMF) physiology has not been well studied in healthy, sedentary individuals. The current study documented the fiber …

THE RELATIONSHIP OF BODY COMPOSITION, MUSCLE FUNCTION, AND MUSCLE FIBER TYPE TO LOWER BODY PHYSICAL PERFORMANCE IN OVERWEIGHT AND OBESE OLDER ADULTS
… the relationship of body composition, muscle function and fiber type and lower body physical performance, in overweight and obese older adults.

The Future is Now in Twisted Coil Polymer Actuators (TCPA)
… and thermal aspects of this artificial muscle fiber. The purpose of this thesis was to find a linear relationship using the LVDT sensor, fabricating TCPA fibers, and interpreting the data. The project tested whether nylon/polymer could be used as a better artificial muscle fiber.</p> …

Effects of beta-hydroxy beta-methylbutyrate (HMB) supplementation on gluteus medius muscle fiber composition and muscle performance in adult Thoroughbred horses exercising to fatigue on a high-speed treadmill
… (HBM), a leucine metabolite, alters muscle composition and metabolism leading to strength and agility improvements in human athletes. To determine if HMB affects athletic performance and muscle function in horses, Thoroughbred geldings were fed a control (CON; n=5) or HMB (n=6) …

Mechanisms of Estrogen-Dependent Dendrogenesis in Motoneurons of the Spinal Nucleus of the Bulbocavernosus
… demonstrated that ERα expression in BC extra-muscle fiber cells defines the critical period for estrogen-dependent SNB dendrite growth, and estradiol treatment during ERα expression in these extra-muscle fiber cells fully masculinizes SNB dendrites. Further, BC ERα expression is sensitive to …

The effects of maternal and postnatal infections with porcine reproductive and respiratory virus on muscle growth and development in piglets
… feed intake, limit weight gain, and decrease muscle growth by directing nutrients away from protein accretion and towards an inflammatory response; however, it is unclear how maternal infection affects offspring skeletal muscle development. Additionally, it is unclear how viral infections …

Pectoralis muscle of turkey displays divergent function as correlated with meat quality
… by a myriad of biological factors which include muscle fiber type composition and heme protein concentrations. These factors either contribute to or are subject to the biochemical events involved in the conversion of muscle to meat. Subtle deviations in the processing environment can also result …
