What happens in the body when a person has a muscle cramp? What causes a cramp?

I chose to do this topic because in class we talked about muscle contractions, and what happens to the body during the process. Thinking logically about muscle cramps, one would assume it has to pair up with muscle contractions being voluntary. However, nutrition and blood flow may also play a key role in muscle cramps.

A muscle cramp is a sudden involuntary muscle spasm. Muscle cramps happen because myosin fibers are not being able to break free from the actin filaments during contraction. This result then leads to prolonged contraction. Since myosin requires ATP to become free from action, not having enough ATP would lead to cramping. Deficiencies such

Effectively, create a story linking all of these terms together. • amount of glucose usage • oxygen intake () • heart rate () • rate of breathing () • number of repetitions of a certain muscular-moving exercise • muscle cramping • rate of ATP production () • carbon Dioxide output () A 3) When you Exercise you notice several things about your body. You breathe heavier and faster, you take in more oxygen and let out more carbon dioxide, your heart beats faster, your muscles hurt and might cramp, and you sweat. During exercise almost all of your body systems focus their efforts on helping the muscles do their work. Other systems, like the digestive system for example, just shuts down so that it doesn't waste energy that the muscles could use. The heart is a good example in the circulatory system that shows how your systems in your body work to help the muscular...

Dehydration

...SCI 241 – Week 5 Assignment: Dehydration Christina Doner Our bodies are made up of mostly water. What does that mean? Exactly how it sounds. Water is found in every part of the body; from tissue, to muscle, and in the bone. Bodies depend on water for lubrication, protection, oxygen in the blood (which too is mainly water), in addition to the delivery of nutrients throughout the body. Consequently, water is essential to the survival of human life. Most importantly, bodies do not store water, resulting in obligatory consumption of water on a daily basis to replenish or restore water that was lost through evaporation or urination. Each person’s body is different, so the best way to configure how much water to consume on a daily basis is to ask a doctor or trained physician. Dehydration occurs when a body is losing more fluids than is consumed, and does not have adequate amount of water and other fluids to carry out its normal functions. Water is crucial in maintaining fluid balance throughout the body. Our bodies require adequate amounts of water in our system to regulate body functions and remain healthy. Some examples of what water does for our bodies are; moistening the eyes, help with chewing and break down of food through the mixture of saliva, and to lubricate and protect our bodies joints. So, the most important task of water is its controlling response to chemical reactions. Water is essential in regulating and maintaining our body’s temperature, assuring it...

Anabolic Steroids Research Paper

...It is illegal to use the drug without a valid prescription and a doctor's oversight. It, also, is illegal for physicians to prescribe growth hormone for uses not specifically approved by the U.S. Food and Drug Administration” (Allender, Steven, Gill Cowburn, and Charlie Foster 1). HGH is said to be the same as taking steroids; it causes an individual to grow muscle mass at a faster rate without experiencing all the pain that comes with it. Many athletes choose to take HGH because it cannot be detected in a urine test. There is one way to find out if an athlete is using HGH, which is through a blood test, but they can only be taken at the Olympic level. HGH is the “go to” drug for professional athletes because it cannot be found in tests, so the only way anyone could find out if one is using it is if they check payment records of the...

Nutrition

...body has more than 600 muscles. Every movement you make, regardless or how slight or exaggerated, involves a muscle contraction. During exercise, your muscles work in concert to move body parts numerous times. Consuming the proper nutrients will allow you to do this action optimally and help speed recovery. ------------------------------------------------- Carbohydrates Carbohydrates are macronutrients that are pivotal for muscles during exercise. When carbs are consumed, they get converted to glucose, which is either used immediately for energy or stored in the muscles as glycogen and used for energy at a later time. If you do not consume enough carbs before a workout, you run the risk of "hitting the wall" or "bonking." This is a point where exhaustion kicks in and your energy levels are tapped. The recommended daily intake of carbs is 130 grams for the average person. Athletes however, should aim for 250 grams or more. Include carb-containing foods in your diet like fruits, sweet potatoes, oatmeal, brown rice, yogurt, whole wheat pasta, whole grain bread and legumes. ------------------------------------------------- Potassium and Sodium Potassium and sodium are electrolyte minerals that play critical roles in exercise, especially when it is intense and of a long duration. Excessive sweating cause’s potassium and sodium levels to become depleted in the body. Your body needs potassium and sodium for fluid balance, nerve signal transmission and muscle contractions. Include...

Hypothyroidism

...Hypothyroidism is an underactive thyroid gland; a glandular disorder resulting from insufficient production of thyroid hormones. This occurs when your body does not produce enough thyroid hormone. The main purpose of thyroid hormone is to "run the body's metabolism," it is understandable that people with this condition will have symptoms associated with a slow metabolism. There are two common causes of hypothyroidism. The first is a result of previous inflammation of the thyroid gland, which leaves a large percentage of the cells of the thyroid damaged (or dead) and incapable of producing sufficient hormone. The second major cause is the broad category of "medical treatments." The treatment of many thyroid conditions is surgical removal of a portion or all of the thyroid gland. Hypothyroidism is diagnosed by a simple blood test to see how much thyroid is in the blood. This blood tests the levels of T4 and TSH (thyroid - stimulating hormone) in the blood. The signs and symptoms of Hypothyroidism are: fatigue, weakness, weight gain or increased difficulty losing weight, Coarse or dry hair, dry or rough pale skin, hair loss, cold intolerance (you can't tolerate cold temperatures), muscle cramps and frequent muscle aches, constipation, depression, irritability, memory loss, abnormal menstrual cycles and decreased libido.

Dehydration

...Dehydration Paper SCI/241 October 27, 2012 Water consumption is important to the body in order to maintain optimum health and function properly. The content of this paper will look at a few of the functions of water in the body and what can happen if enough water is not taken in, resulting in dehydration. Following the functions of water, I will discuss dehydration and its stages and symptoms. I will also cover the essential electrolytes in the body, sodium, potassium, and chloride their location, functions, intake recommendations, and the dangers of taking in too much of each. Alcohol and caffeine can have a negative effect on how the body uses water, so I will discuss and explain how both of these substances affect water in the body. Lastly, this paper will discuss ways to avoid becoming dehydrated. Water makes up over half of our body weight. In men, it is approximately 60 percent of their body weight and for women it is approximately 50 percent (Grosvenor & Smolin, 2006). Some of the main functions of water in the body are to help lubricate joints, regulates body temperature, and helps remove waste from the body and aids in the digestion process. When a person experiences joint pain, it is a sign of lack of water. Cartilage within the joints is about 80 percent water and provides a smooth surface for the joints to move on, but that is only the case if enough water is consumed. Lack of water means less lubrication for the joints causing friction...

Which of the following choices is a good description of you in that picture? I'm the girl going into the Girls' room, and I'm giving my friend a look across the hall that means, "Ugh - I'm going to change my pad (or tampon), and I'll see you later." I've got cramps, and right now I can't remember why I ever wished for my period to come in the first place. Click here Pregnant? Click Here [pic] I'm the one looking wistfully at my friend, wondering when my period is going to come, if ever! It seems like I've been waiting for months, my supplies are all ready, I know exactly what it's all about, so when am I going to catch up?! I'm the guy standing at his locker a few feet from the Girls' room door. I understand most things about puberty, and I know that girls get their period and that's why they have to make more trips to the Girls' room and stuff, but it's still a little foggy in my mind. Do they know it's coming? Can they bleed too much? Does it feel weird? Chances are you can recognize yourself in choices a, b, or c - or some combination of the three. Menstruation (or a period, as it's often called) represents a major stage of puberty in girls; it's one of the many physical signs that a girl is turning into a woman. And like a lot of the other changes associated with puberty, menstruation can be confusing for girls (and guys). Some...

Badminton

...Badminton Injury does occur to a player when they are not properly warmed up or their techniques are not correct. It also happens when fatigue kicks in after playing or training for too long. Also there are times when you don't really know what hit you. | So I think it is good that you understand the few common badminton injuries in case you are unlucky and injured yourself. However, you should always seek professional medical advice if that happens. Acute Badminton Injuries Ankle Sprain This is a common badminton injury, usually accidental. It may occur when the athlete steps on his partner's foot and land with a plantar flexed, inverted and supinated foot. Most sprains occur on the lateral ligament complex, a group of ligaments on the outside of the ankle. It will result in a painful swelling in the outer aspect of the ankle, usually causing a partial or total rupture of one or more ligaments. Apply RICE (Rest, Ice, Compress, Elevate) to reduce swelling. It may also result in other complications eg. fracture, tendon injuries and loss of proprioceptive control. It may take days to a few months to heal with adequate rehabilitation. Meniscus Tear Normally caused by a sudden twisting movement of the knee during footwork resulting in the tear of the meniscus. There will be pain in the joint-line of the knee, mild swelling and unable to flex or extend the leg in full. It may be having accompanying collateral or cruciate ligament injury.
