Exercise Muscle Cramps Research

Muscle contraction can be understood as the consequence of a process of transmission of action potentials from one neuron to another. A chemical called acetylcholine is the neurotransmitter released from the presynaptic neuron. As the postsynaptic cells on the muscle cell membrane receive the acetylcholine, the channels for the cations sodium and potassium are opened. These cations produce a net depolarization of the cell membrane and this electrical signal travels along the muscle fibers. Through the movement of calcium ions, the muscle action potential is taken into actual muscle contraction with the interaction of two types of proteins, actin and myosin.

The causes for this muscle disorder are not completely understood, but there are several theories. According to the Mayo Clinic Staff, muscle cramps are caused by overuse of muscle, dehydration, muscle strain, or simply holding a position for a long period of time. In their article, “Muscle Cramps,” they also stated that cramps may be related to underlying medical condition such as inadequate blood supply, nerve compression, and mineral depletion (Mayo Clinic Staff, 2013). Getting inadequate blood supply affects the arteries that deliver blood to the legs producing cramps in the legs and feet while exercising. Another article called, “Muscle Cramps-Symptom Evaluation” also lists anemia, medications, kidney disorders, and hormonal problems as causes for this disorder.

I know that the more times I skip, lactic acid will build up in my legs, from my own experience this makes you fell horrible. As our bodies perform strenuous exercise, we begin to breathe faster as we attempt to move more oxygen to our working muscles. The body prefers to generate most of its energy using aerobic methods, meaning with oxygen. The cells follow the aerobic process when the blood supplies enough oxygen to the cells, which is:- Glucose+ oxygen—>Carbon Dioxide+ water+ Energy. But when the blood cannot get the needed oxygen to the cells, it has to get the energy from the glucose in another way. The cells use the anaerobic pathway; It does this then by breaking glucose down into lactic acid, Glucose—>Lactic Acid+ Energy. Lactic acid is released into the muscles when they have used up glucose stores but still have intense energy needs. Small amounts of lactic acid operate as a temporary energy source, which helps you avoid fatigue during a workout. However, a build-up of lactic acid during a workout can create burning sensations in the muscles that can slow down or halt your activity. This is not an effective energy source for long periods of exercise, so the blood takes lactic acid to the liver which coverts it back into glucose to be used in the normal aerobic process. Scientist are always looking into ways to decrease lactic acid build up in elite athletes so they can perform faster

With the extra potassium, you are protecting the heart and increasing calcium absorption. Drink this smoothie before or after a vigorous workout to prevent muscle cramps.

To investigate the effect of food GI content on exercise induced cardiovascular, metabolic and respiratory function.

many people are scared of eating fat and carbohydrate because they think that it will increase the fat percentage. Therefore get that carbohydrates and fats are good for providing energy the body. If you eat a banana before your training session, it will help you work out with good energy. You can also consume a tablespoon of honey with water before exercising. Honey will dissolve fast in your body and it will enhance the energy level in your body.

Creatine is has been studied for some time and has been found to reap very effective results. Creation is made naturally by one’s body, but it can be used as a nutritional supplement to improve one’s overall health or athletic performance. As described in the article titled “Creatine: MedlinePlus Supplements”, creatine is produced in the liver, kidneys, and pancreas from the combination of the amino acids glycine, arginine, and methionine. This natural supplement helps make a substance called adenosine triphosphate, or ATP, which provides energy for muscle to contract. Food sources high in creatine include fish and meats, but creatine can also be found as a nutritional supplement in the form of powders, pills, capsules, and drinks. Several

When a muscle is overworked, the muscle can run out of all natural energy. Without energy, the muscle, or muscle pairs, can no longer contract. This condition is known as muscle fatigue. During a state of muscle fatigue, the muscle tissues loses oxygen, and the muscle is left with little to no air.

Rest days are incredibly important in regards to muscle fatigue and athletic performance, because when you are resting your muscles recover and repair themselves. As a rough rule, aim for 7 hours minimum of sleep a night. Most professional Crossfit athletes sleep between 8 – 10 hours.

In contrast to athletes consuming recovery drinks for vital nutrients, studies have shown that food like fresh fruits and veggies are also great for replenishing athletes. Bananas, for example, contain necessary vitamins, minerals, nutrients, and electrolytes. This makes them an excellent post-workout snack. Furthermore, bananas are commonly known for having a large amount of potassium, which helps keep an athlete’s body healthier by protecting muscle mass (Michelle). In addition to having an abundance of potassium, bananas are an exceptional source of another crucial mineral: magnesium. Magnesium helps athletes recover by keeping their blood pressure levels regulated. This demonstrates that putting foods like bananas and other fruits and veggies

How ever there was a huge change in food intake after participants engaged in High Intensity Exercise. There was a difference shown with a significance of (P<.05). This helped the researchers come to the conclusion that High Intensity workouts are beneficial for the 24 hour energy balance. However it found that these effects usually don’t carry over into the next day. It also showed that while the consumption levels fell the types of food which they consumed did not change

Pain is a common symptom that people suffer at some point in their life. Muscular pain is the leading cause of all pain. Muscles being the cause of pain was frequently ignored until Travel and Simmons published a book on "Myofascial Pain and Dysfunction". This book had entirely changed the concepts of pain and compelled medical professionals to consider muscles as the potential source of pain. This book was published in two volumes, first on upper body and second on lower body. The authors of the book were married couples who had identical interest in the field of Myofascial; otherwise called as Muscular Pain. After many decades of dedicated clinical work, they came up with this grand publication, which astonished all the medical professionals dealing with pain. Any publications done on myofascial pain tend to use this book as a major reference.

For example; increases in 100 and 200m swimming performance (22) and increases in 2000m rowing performance (18) as well as increases in cycling capacity (17) have been demonstrated (for reviews see Refs. 10, 16). However, the precise mechanisms by which carnosine may elicit increases in exercise performance and capacity remain to be fully elucidated. During high intensity exercise, hydrogen cation (H+) accumulation is significantly increased, which results in significantly decreased intracellular pH (23). Furthermore, H+ accumulation is reported to disrupt the ability of the muscle’s contractile machinery to function (8, 12). Due to carnosine’s imidazole ring having a pKa of 6.83, it is well acknowledged that carnosine is a perfectly suited intracellular pH buffer across the entire physiological range (4). Therefore, during high intensity exercise where H+ accumulation is likely to be the biggest contributing factor that limits exercise performance, carnosine’s ability to increase intracellular buffering capacity and maintain muscular function, is suggested to be the most pertinent mechanism by which carnosine evokes an ergogenic effect (27). Hill et al., (17) suggested increased intracellular buffering capacity resulting from an increase in muscle carnosine concentrations explained a significant increase (TWD: +16.2%) in cycling capacity following 10 weeks of BA

Muscular fatigue occurs when the muscles of the vocal system are overused. This can happen if you were to sing too much, too loudly or out of range. It is often described as a tight and/or sharp pain in the general throat area.

When Someone has strong muscles in a certain area, they are more likely to have less pain there. When people often use their muscles they become physically strong. Having strong muscles can make someone feel faint less often.
