in fact it can may it a lot worse! What Is Back Pain? This medical condition comes on many forms, including upper back pain, middle pain, and lower back pain. Dorsalgia is pain felt in the back that usually originates from the joints, nerves, or muscles. No specific cause of the pain can be identified in up to 85 percent of cases. Back pain is one of main reasons

consists of many tissues, but the three main types of tissue that make up the heart are; cardiac muscle tissue, nerve tissue and blood tissue. The cardiac muscle tissue is only found in the heart. It plays the most important role in the atria and ventricles of the heart. It contracts and makes the rhythmical beating of the heart and circulates the blood around the body, making the heart pump. The cardiac muscle sends electrochemical signals all around the heart so that all the cells in the body receives

Smooth muscle The function of the Smooth muscle are the muscle we do not consciously control eg those that are found in the walls of blood and lymphatic vessels, in respiratory, digestive and genito-urinary systems. These muscles work automatically weather we want them to or not. The structure of the smooth muscle is they have spindle shaped cells with no distant cell membrane and only one nucleus, bundles of the fibre we see with the naked eye. Skeletal muscle the function is these are the muscle

stores in muscle, and perhaps secondarily to excessive metabolic acidosis as a result of anaerobic glycolysis. Sprinting events are the fastest competitions in track, it happens so quickly and it seem like a single sprinting stage. But sprinters all go through three distinct phases: • Drive: All sprinters begin at this phase. When he/she bursts from a dead still position into a sprint. Sprinters begins in a crouched position,

Balance According to Gametta and Gray 1995, balance is the single most important component of athletic ability because of its major involvement in the majority of all sporting movements. Balance is required for every tasks on a day to day basis. The body works hard in everyday movements to stay balanced, even in the most simplest of actions. Balance has also been described as stability, postural control and dynamic control. Stability is defined as the state of a joint remaining or quickly returning

an eighteen year old female volleyball player. This athlete came to the Athletic Training Room with idiopathic scoliosis that had gone untreated since the age of 12. She experiences severe pain in the thoracic spine as well as in the surrounding muscles. Being that she waited 6 years to have the surgery, it might have increased her risk for complications. The surgery that this athlete will undergo is a spinal fusion surgery of the thoracic spine(T11-T12). It is better that the spinal fusion surgery

Introduction: According to the American College of Sports Medicine 1,flexibility is an important component of good physical fitness and health. Therefore, for physical activity programs, muscles stretching exercise is an important component. Sedentary or less flexible subjects may perform the VM during stretching exercises due to difficulty in reaching and sustaining extreme ranges of motion. Methodology: 40 participants of age group 18-25 years having either hamstrings or pectorals tightness were

causes the muscle to stretch, and according to Purves (2008), this evokes excitation of the Ia sensory axons, innervating the muscle spindles. This excitation reaches the alpha motor neurons in the spinal cord or brainstem and then return to the muscle that has been stretched. It is important to note that muscles are ways under a degree of tension, which is mediated by group II afferents; this reflex circuit is responsible for maintaining the level of tension in muscle, called muscle tone. Purves

Physical therapists widely use joint mobilization techniques consisting of controlled skilled passive movements to the joint structures with appropriate velocity and amplitudes aimed at increasing joint range of motion ROM, decreasing pain and improve functional activities. Maitland joint mobilization techniques was developed by an Australian physiotherapist named Geoffrey Douglas Maitland. Maitland technique has five basic grades of joint mobilization depends upon the rate and rhythm of movement

variations of "static hold" push-ups have been mastered, is to progress to "negative" push-ups. The term "negative" is used to describe what is technically known as an eccentric contraction. During the down phase of the push-up the chest and the triceps muscles, or primary movers, are lengthening, which describes what occurs during an eccentric contraction. There is the belief that strength is built during the eccentric, or negative phase of an

File one Summary: Skeletal muscles are made out of striated subunits called sarcomeres, which are made out of the myofilaments actin and myosin. Skeletal muscles contain myofibrils. Every myofibril is striated with dull and light bands. I bands contain just thin fibers, made fundamentally out of actin. Myosin cross bridges stretches out from the thick fibers to re slim fibers. Very still, the cross bridges are not connected to actin. The cross-bridge heads capacity as ATPase enzymes. ATP is split

linking muscle to bony attachment points and in the case of the intermediate tendons that will act to link a muscle belly to another (Benjamin and Kaiser, et al). Tendons are a uniaxial and assist in force transmission thus being able to withstand external forces from multiple planes and angles (Kannus, 2008). Tendons are also responsible for storage of power and changes in the mechanical energy of the body of which in turn reduces muscular work by

are over 650 muscles in the human muscle system in which contribute to complete physical activities such as running, walking, dancing, speaking, and even breathing. (Every day myst) Muscles are organized into three classifications skeletal, cardiac, and smooth. Skeletal, smooth, and cardiac muscle are found in particular organs. The heart is the only organ that is composed of cardiac muscle. As the heart has a life time job in pumping the blood throughout the body. The vigorous muscle contains cell

There are very fast, involuntary and unconscious reflexes controlled by the spinal level, that are influenced directly by afferent information from joint receptors. These reflexes are coordinatinated between agonist and antagogonist muscles (p17). Sherrington(1906) identified the coordination as the law of reciprocal inhibition: When an agonist contracts, its antagonist automatically

as different types of fitness (Martens, 2004). For example, running would require a great deal of aerobic and cardiovascular fitness. However, archery requires little of these and focuses more on muscle strength and dexterity. Equestrian sport requires several aspects of fitness such as balance, muscle strength and aerobic fitness. However, unlike other sports, which aspects contribute to success is poorly researched. In general, with a few exceptions, fitness of the rider is not focused on in equestrianism

your heart rate and keep it high for a certain period of time after you stop doing the exercise. These exercises can also be called aerobics. There are many benefits of cardio exercises. The first and most important is it helps strengthen the heart muscle and lungs. Weight loss is the main advantage of the day, and also maximizes the amount of oxygen that the body takes and also improves blood circulation. The body 's immune system is stimulated with these exercises. To do cardio exercises, you will

Intro: A boxers diet should consist of carbohydrates, protein, fats, and lots of water. Boxing is a high intensity sport which needs a large amount of energy. If these needs are not met, your body can very easily disperse all energy within minutes. With the act of holding your arms up, blocking heavy hits, and giving them but also giving 110% concentration, the 12 rounds of 3 minute bursts will easily allow most, if not all, of a person 's energy. Carbohydrates: Carbohydrates are an important part

Physiological effect of emotion on sports performance 3.1 Cortisol and overtraining - the negative emotional cycle Participation in sports can also contribute in physiological effect to the body that further causes emotional response which affects sports performance. Cortisol, also known as a glucocorticoid functions so that it increases the amount of energy available to the body. For example, when waking up in the morning, the level of cortisol temporarily increases which makes us feel more energetic

then the quality of life of a patient should increase (Ratchford et al., 122). The study conducted by Manigandan et al (2014) describes how patients who underwent electrical stimulation on their shoulder reported a sense of well-being after the muscle contraction and movement of the arm. One scientific test used to diagnose quality of life is the SF-36 test. After undergoing functional electrical stimulation, Ratchford et al (2010) conducted the SF-36 test on patients. The physical health score

protein powders and see how the amino acids in them help our bodies to build muscle and how our bodies benefit from them. Protein powders come in all types and flavors and their main purpose is to give your body the amino acids and nutrients that it needs but might not get as easily. They help your muscles grow faster and stronger. Without protein, our muscles wouldn’t heal quickly or correctly which could lead to muscle injuries. In this research project, the two protein powders that will be looked
