      While muscle regeneration has been extensively studied in animal and cell culture models, in vivo myogenesis in adult human skeletal muscle has not been investigated in detail. Using forced lengthening contractions induced by electrical stimulation, we induced myofibre injury in young healthy males. Muscle biopsies were collected from the injured leg 7 and 30 days after muscle injury Cited by: The human musculoskeletal system (also known as the locomotor system, and previously the activity system) is an organ system that gives humans the ability to move using their muscular and skeletal musculoskeletal system provides form, support, stability, and movement to the :

    Wow, carnosine is MUCH more important to a horse than a human: Traditionally, the importance of carnosine as a physicochemical buffer in human skeletal muscle has been largely ignored, because various calculations and measurements have designated its relative contribution to only 8–15% of total buffer capacity (Hill et al. ; Parkhouse et al. ; Hultman and Sahlin ).   Many studies concerning mitochondrial dysfunction with aging have failed to take into account the location of specific populations of mitochondria within skeletal muscle, which can differ with regard to oxidative capacity and adaptability to contractile activity (36,37). In the current study we considered a distinct portion of the muscle fiber Cited by:

The buffer systems functioning in blood plasma include plasma proteins, phosphate, and bicarbonate and carbonic acid buffers. The kidneys help control acid-base balance by excreting hydrogen ions and generating bicarbonate that helps maintain blood plasma pH within a normal range. Protein buffer systems work predominantly inside cells.

Skeletal muscle buffering capacity (βm), enzyme activities and exercise performance were measured before and after 4 weeks of high-intensity, sub maximal␣interval training (HIT) undertaken by six well-trained competitive cyclists [mean maximal oxygen consumption (O 2max) = ml kg −1 min −1].HIT replaced a portion of habitual endurance training and consisted of six Cited by: Get this from a library.

This adaptability of muscle tissue results in the ability to function efficiently over a wide range of conditions and is based on adaptive changes in muscle power output, rapid movement, and/or resistance to fatigue.

Quantitative Human Physiology: An Introduction, winner of a Textbook Excellence Award (Texty), is the first text to meet the needs of the undergraduate bioengineering student who is being exposed to physiology for the first time, but requires a more analytical/quantitative approach.

This book explores how component behavior produces system. Muscle tissue is a soft tissue, and is one of the four fundamental types of tissue present in animals. There are three types of muscle tissue recognized in vertebrates. Skeletal muscle or "voluntary muscle" is anchored by tendons (or by aponeuroses at a few places) to bone and is used to effect skeletal movement such as locomotion and in maintaining : D   Carnosine was first discovered as an intracellular pH buffer in by Severin and colleagues [] using frog muscle uent studies examining this relationship in human muscle tissue followed thereafter [13,14,29,30,31,32].When skeletal muscles are involved in moderate to intense exercise, there is typically a generation of lactic acid and subsequent dissociation into lactate and H+ Cited by: David Bishop, Johann Edge, Alberto Mendez-Villanueva, Claire Thomas, Knut Schneiker.

High-intensity exercise decreases muscle buffer capacity via a decrease in protein buffering in human skeletal muscle.

Many drugs can cause unexpected muscle disorders, often necessitating the cessation of an effective medication. Inhibition of monocarboxylate transporters (MCTs) may potentially lead to perturbation of l-lactic acid homeostasis and muscular toxicity.
