Flexibility And How Does It Work

* A stretch reflex is a contraction of a muscle when an attached tendon is pulled. Stretch reflexes are important in maintaining proper posture. Stretch reflexes are used to determine which areas of the body the central nervous system are not responding to. For example, if you tap your knee to check for reflex and the leg doesn’t move, you then know that the peripheral nerves that lead to the knee are nonresponsive and/or the brain is not receiving a signal from that particular area.

For example, some joints in humans simply are not meant to be flexible, there is internal resistance within a joint, there are bony structures which limit movement, the elasticity of muscle tissue differs and muscle tissue that is scarred due to a previous injury is not very elastic. Also, the elasticity of tendons and ligaments is very limited. Ligaments do not stretch much and tendons should not stretch at all. The elasticity of skin actually has some degree of elasticity, but not much. Also, the temperature of the joint and associated tissues are musically more flexible at body temperatures that are 1 to 2 degrees higher than normal.

The purpose of this experiment was to be able to test different intensities of warm-up conditions changes in the heart rate, skin temperature, electromyogram (EMG), and the contraction of the bicep brachii. Testing three different intensity conditions to determine which warm-up is more efficient on muscle conditioning. Bicep stretches, cardio, and aerobic stretching were the three different conditions because they focused on different muscles in the body. The warm-up that is able to efficiently deliver more oxygenated blood to the muscle is the most affective. Therefore, the predictions is that aerobic stretching will enhance muscle performance of the bicep brachii. This will happen because aerobic stretching is a high intensity warm-up that increases heart rate and cardiac output.

for a number of tests, including flexibility and power and strength tests, a full warm-up should be conducted to reduce the possibility of injury

The first principles are warm up and cool down. The purpose of any warm up and cool down is to reduce the risk of injury and soreness. For this to be applicable, a warm up must be sustained for no less than 10min and for elite athletes, at least 30min. Included in this warm up must be stretching to loosen up the muscles. There are no physiological adaptations that

Both the DNV and Joint Commission are organizations that conduct inspections and accreditations. Accreditations have an impact on the way hospitals operate only because a hospital makes critical decisions of how it treats diseases, assigns clinical staffing and stores its medications.

During warm-up, the type of muscle fiber is slow twitch muscle fibers. Slow twitch fibers are used for endurance type activities and are particularly suited to aerobic type activities. They contain an increased number of mitochondria. They are also capable of using oxygen for the production of energy within the muscle. This system uses glucose or fat in combination with oxygen to produce energy. The by-product of this system is carbon dioxide, water, and heat. During cooldown, the type of muscle fiber is fast twitch fibers. Fast twitch muscle fibers have less mitochondria and less capacity for oxygen use in the production of energy within the muscle. This makes them better suited to anaerobic activities such as running. They produce energy anaerobically without oxygen. This system uses glucose as a prime energy source. They can generate more force, but quicker to fatigue to focus explosive movements for only a limited number of repetitions for maximum effectiveness. Warm-up increases the temperature and flexibility of the muscles and helps the muscles be more efficient and safer during your workout. A warm-up before high-intensity aerobic activity allows a gradual increase in heart rate and breathing at the start of the activity. However, warming up is to begin with low-intensity running. It is slowly increasing the intensity as people progress through the warm-up period. They can include short segments of gradually increasing intensity along with long rest intervals as they get closer to the high-intensity portions of their

Vasoconstriction- The sympathetic nervous system on the brain causes the heart rate to increase making your veins constrict. This is called vasoconstriction and the blood flow will be directed right to the muscle to help it work harder. Temperature increases to help the flow of blood around the body. Your reflexes will be quicker and your muscles tense. This facilitates the blood carrying oxygen and removing waste products.

Before I can talk about flexibility, we need to define what a "tight muscle" really is. A very big flexibility misconception is that muscles need to be physically lengthened and the best way to lengthen muscles is through stretching. This is simply not true! Muscles already have all the length they need and attempting to change that length via intense stretching is liable to cause ligament damage rather than actually increase the range of motion.

Flexarite then holds back the explanations that rationale inflammation which in turn provides immediate remedy to your joint pains. Flexarite will then fortify your physique's flexibility. Flexarite has a very strong enzyme antioxidant that absorbs 1 million free radicals in your physique delivering support towards additional oxidative damages. Flexarite raises the body's antioxidant safeguard as well by arranging joint tissue blocks to shield the

After reading and viewing the mob mentality pieces, I conclude in which mob mentality can create a cruel mindset that effect people negatively. One reason I believe that mob mentality is cruel is because Edmonds states that mobs, “lose their individual values and principals and adopt the group’s principles, which, during a riot, are usually to cause destruction and avoid detection.” The above states that people lose their ethical thinking, and decide to go along with the group and make horrendous decisions. Even though the mobs can be powerful and exciting, the individuals in a mob make bad decisions and feel at the time they will not be affected by the situation(s). In the photograph, the illustration shows how cruel a human being can be.

The warm up should increase the heart rate in order to pump more blood around the body, to the muscles that are currently working. This will allow more oxygen to the muscles and the body and muscle temperature will increase. The improved temperature of the muscles makes them more flexible and supple, this helps prevent injury in certain joints.

Range of movement- This is linked to muscle pliability as the warmer the muscles get, the better the elasticity which enable the body to move easier and have a better range of movement around a joint. Exercise increases the production of synovial fluid at a joint, therefore keeps the joints lubricated and makes them suppler. Consequently, allowing a larger range of movement throughout the body. For example if an individual went on the cross trainer for 10 minutes and then went on to the rowing machine; they would have an increased range of movement at their joints, making it easier to exercise on that machine due to the muscles already being warmed up.

Flexibility means change what you do. It means according different requirements or things to fast handle with, making change or decisions , flexibility arranging and coordinating operations’ work.
