Muscle Safety Research Paper

Every time our body moves, our muscles contract. As the muscle contracts, the muscle becomes fatigued; unable to maintain force output. There are two types of fatigue; central and peripheral (1). Central fatigue involves the central nervous system, whereas peripheral fatigue includes fatigue outside of the central nervous system in the muscles (5). Changes to these systems affect the rate at which the muscle fatigues, including the speed of contraction, the strength of the load, and feedback (5). Therefore, the purpose of this study was to determine whether increased force would influence the time of fatigue, with and without visual feedback. It was hypothesized that as the magnitude of force increased, the time to fatigue would decrease, whereas while the magnitude of force decreased, the time to fatigue would increase. Overall, visual feedback would have increased time to fatigue, compared to non-visual feedback, which would have decreased time to fatigue.

MuscleTech Nitro-Tech 2 is part of the performance series that contains whey isolate and lean muscle builders (peptides) to build 70 percent more lean muscle than regular whey. This is an ultra pure whey isolate that has been enhanced with creatine and amino acids. In the past, bodybuilders had few options for protein sources that had been scientifically formulated. That has changed with Nitro-Tech. MuscleTech has created a protein formula that packs on more muscle than regular whey protein due to their special process.

Nobody should consider the use of human growth hormones (HGH) or anabolic steroids. While two muscle building additions increase muscle mass and decrease body fat, there are many reports about their effects. Cough and carpal tunnel syndrome are just two of the most common problems that include the use of HGH and steroids.

You can have many muscle injuries, so we are going to be diving into some of the main muscle injuries.

Many processes happen within the human body in regards to exercise and pain. One major complaint within athletics is muscle soreness caused by exercise. Muscle soreness can affect performance negatively during activity. Delayed-Onset Muscle Soreness (DOMS) is a sub-type of soreness that intensifies after twenty-four to forty-eight hours post exercise. It is thought to be caused by small tears in the muscle tissues, inflammation, or it could be due to the disruption of connective tissue of the muscle tissue, stiffness (Prentice, 2009, p. 273). CWI is thought to decrease the effects of DOMS and promote an active recovery by decreasing inflammation and metabolism, which can slow down the physiological responses of injury. (Knight and Draper, 2013, p. 214)

Every exercise we do or sport we play use one of muscle fiber types FOG, SO, or FG. A sport that uses one of the muscle fibers is marathon runners. marathon runners need to use SO types fibers to run. Because SO fibers contract at a slow rate marathon runner do not get tired fast from their legs. Which is good for marathon runners who run long distance and need a fiber that is fatigue resistant to complete the marathon. Another sport is wrestling which uses FOG fiber type. People who do wresting need Fog fibers because they need to sustained a rapid contraction of intermediate fibers throughout the 2 to 3 mins of wresting they do. Finally, sprinting is the final sport that uses the last muscle fiber type FG. Sprinter need FG fibers because

The stress placed on your muscles during exercising leads to tiny tears in your muscle fibres occurring, these tears will cause swelling in your muscle tissues, this creates pressure on the nerve ending and pain. In order to repair these micro tears protein, sufficient fuel and rest is needed making the muscle stronger.

Delayed-onset muscle soreness (muscle fever)—muscle pain and weakness that starts up to a day after unfamiliar exercise, peaking up to 2 days later

The causes of fatigue during exercise could be any combination. Some happen within the muscle itself, like the decreased rate of energy production ATP, anaerobic glycolysis, and aerobic metabolism. The accumulation of metabolic lactate and H+. The failure of the muscle fiber's contractile mechanism from a injury of some sort. Also alterations in neural control of muscle contraction such as changes in the brain or central nervous system. It all depends on the type and intensity of the exercise, the fiber type of the involved muscles, and even the nutritional diet. (Kenney, 11/2011, p. 128)

Awareness to nutritional importance of best post-workout meal for lean muscle is imperative. Pushing yourself too much to heavy gym exercises may damage your muscles especially when not supported by proper and best post-workout meal for lean muscle. High intensity trainings and exercises depletes your energy stores such as carbohydrates, proteins and others nutrients. That is why you need to have adequate and proper nutrition before and after workouts. Here are best post-workout foods to guide you in your physical fitness goals.

Different muscle groups “learn” to work together to perform and stabilize a movement. For example, while the Biceps Brachii produces the main force for the bicep curl, the Brachialis’ role in stabilization is increased, and the Triceps Brachii relax to allow for the Biceps to exert greater force.

some of the signs and symptoms of this disease include muscle weakness. the muscle weakness is a slow process and this disease is considered to be an autoimmune disease. the disease can happen to adults and to children. according to the national institute of neruological disorders and stroke the prognosis for individuals with a myopathy varies. some individuals have a normal life span and little or no disablity. for others, however, the disorder may be progressive, severely idsabling, life-threatening, or fatal. it is estimated that the disaease willa fect 1 out of every 50,000 individuals.

But first of all, you need to know if you don`t know already, what causes muscle soreness. It is believed from researchers and the medical profession that the pain is caused by "Micro-Trauma" in muscle fibres, and it is solely triggered by the negative movement according to the body, The theory is, by the doing an exercise, like when the activity of raising and lowering a barbell or bench press, and even a squat thrust or a curl rep (repetition) are accomplished.

Muscle fatigue is present if there is a decrease in the capacity to perform physical actions with the same muscle (Enoka & Duchateau, 2008). This is due a decrease in the energy available for the muscle to use, therefore using anaerobic respiration as a source of energy as oxygen is depleted and aerobic respiration can no longer be used.
