Muscular system

Muscle tissue is one of the four tissues types that exist in the human body. There are three different muscle tissues, skeletal, cardiac, and smooth. Skeletal muscle tissue cells are long, striated, and have many nuclei. Cardiac muscle tissue, just like the skeletal is also in striations. These cells are short and branched. Unlike, the skeletal muscle tissue these cells die single nucleated. They are connected by intercalated discs. Smooth muscle tissue is not striated. Its Cells are short and…

different diets, supplements, and training techniques to improve their performance. The use of nutritional ergogenic aid in the sports industry is very well known for improving performance. Most ergogenic aids affect the metabolism and the central nervous system to reduce body fat content and stimulate protein synthesis to increase muscle mass or create lean body mass. One of the most used supplements among athletes is creatine, commonly used for increasing muscle mass. As some athletes might…

1 Name of your Genetic Disorder: Duchenne muscular dystrophy (DMD) 2 Gene locus on which chromosome: Gene locus on the short arm of the X chromosome named Xp21. 3 Type of disorder (autosomal, sex-linked, dominant, recessive, aneuploidy?): DMD has an X-linked recessive inheritance pattern. 4 Symptoms of the disorder: According to the National Human Genome Research Institute , generally, the symptoms of DMD appear between the age of 1 and 6. Since the age of one, the patient…

Calf strains are a very well known problem for runners, soccer and basketball players, gymnasts, and dancers, and even more common in athletes who are advancing in age. The calf muscle consists of nine different muscles; the gastrocnemius, soleus, and plantaris muscles attach onto the heel bone and they all work together to produce the upward and downward motion of the foot (calf raise). The other six muscles cause knee, toe, and foot movements in different directions, however those muscles are…

Injury Details Hamstring injuries comprise a significant amount of acute musculoskeletal injuries arising during sporting activities (Canale et al, 1981). Usually, athletics, football and rugby athletes are notably prone to hamstring injuries due to the sprinting demands of their sport. It is, however, a major concern that one-third of hamstring injuries will recur, possibly during the first two weeks post return to activity. A premature return to play and/or a deficient rehabilitation…

The ability for muscles to contract and shorten to produce movement lies within its structure at a cellular level. The muscle organ is surrounded by a fibrous connective tissue called the epimysium, continuous to the perimysium, which separates the organ into small bundles called fascicles. Each fascicle can be further separated into muscle fibers by the endomysium. The plasma membrane of an individual muscle fiber is called the sarcolemma, which plays a major role in generating an action along…

From genetics to snug shoes, the cause of a hammertoe varies. Though painful, what remains certain is early detection as the key to a speedy recovery. A hammertoe is that unusual bend in your third, fourth, or little toe. With time, it can worsen, but by recognizing the issue early on, you can lessen the likelihood of surgery. We understand — you want to get back on your feet sooner than later. That's why Dr. Cox has outlined his pro-tips for healing, so you can return to life, uninterrupted.…

continue contracting. Smooth muscle known as nonstriated muscle is an involuntary muscle found in the walls of the blood vessels and different hollow organs. Around blood vessels it regulate blood flow through vital organs, in the digestive and urinary systems around the rings called sphincter, assist in the movement of materials along the passageway…

you ask people their opinion on what the best rep range is for gaining muscle mass and what is the best for leaning out, I would be willing to bet that over 90 percent of the answers you receive would be: low reps for mass and high reps for cutting. If you've been in the gym mix for any length of time, you've probably heard the same. The problem is that this philosophy isn't necessarily accurate. Let's first tackle gaining muscle mass. If you were to lift heavy weights and perform low reps, you…

One of the main goals in the field of exercise science is to determine methods of enhancing performance during exercise or competition. When comparing methods of performance enhancement two essential theories come to mind: utilization of the stretch-shortening cycle (SSC) and post activation potentiation (PAP), which both result from pre-activation (Fukutani, Misaki & Isaka, 2016, Nibali, Chapman, Robergs & Drinkwater, 2013) The SSC focuses on increases in muscle force output through a…
