How running preserves the memory

Exercise has long been known to combats stress, but a study by Brigham Young University suggests that it can also combat forgetfulness. The researchers found that running protects against the negative effects of stress on the hippocampus-the part of the brain responsible for learning and memory.

Within the hippocampus, memory formation and recall work best when the connections between neurons-synapses, are strengthened over time, a process called long-term potentiation (LTP). Chronic or prolonged stress, however, weakens the synapses and with them the LTP, negatively impacting memory.

The ideal situation for improving learning and memory would be to experience no stress and to exercise. To study the link between memory, stress and exercise, researchers divided mice into four groups: sedentary no stress, exercise no stress, exercise with stress, and sedentary with stress. The mice were then exposed to stress inducing situations, such as walking on an elevated platform or swimming in cold water, or put on a running wheel depending on their grouping.

To determine how the variables affected each group's memory, the researchers used electrophysiology to measure the LTP in the animals' brains. They found that the stressed mice who exercised had considerable higher LTP rates than those who had not exercised. The researchers also used a maze-running experiment to test the mice's memories. The stressed mice who exercised performed just as well as non-stressed mice who exercised.

Additionally, the exercising mice made significantly fewer memory errors in the maze than the sedentary mice. The findings suggest exercise is an effective way to protect learning and memory mechanisms from the negative cognitive impacts of chronic stress on the brain.

How to fight inflammation with exercise

Inflammation is the body's way of healing itself after an injury and protecting itself from infection; but chronic inflammation is associated with different kinds of diseases.

During exercise like running, jumping, jogging, swimming and walking muscle cells release a small protein known as Interleukin 6, IL-6, which fights an inflammation. Any forms of exercise that you can think of will produce the same Interleukin 6. It has several anti-inflammatory effects; it lowers levels of a protein called TNF alpha, which triggers inflammation in the body.

It prevents the effects of a protein known as interleukin 1 beta, which triggers inflammation that can damage the cells in the pancreas. The quantity of IL-6 release by muscles is determined by quality of time spent during exercise, the longer you engage in exercise, the more IL-6 will be released into your body.

Regular exercise induces a strong anti-inflammatory effect on the body and it prevents an inflammation. It also increases levels of protein, known as Interleukin-15 (IL-15), in muscle cells. IL-15 regulates the accumulation of abdominal fat, with higher levels of IL-15 providing protection against abdominal fat buildup.

Regular exercise should be used as part of the treatment for chronic inflammatory diseases. Exercise serves as natural, anti-inflammatory and metabolism-improving 'drug'. It can be useful for treating type 2 diabetes and cardiovascular disease.

Effects of marathons on your kidney

Marathon is a long distance running race with an official distance of 42, 195 kilometers, running marathon can harm your kidney.

Kidney may not be able to filter waste during marathon as s result of reduction in blood flow to the kidney during the race.

Dehydration during the race can cause increase in temperature, the body temperature can rise to 104f during the race, the heat stress can damage the kidney.

Waste product like creatinine in the blood and protein in the urine are the common kidney injury experienced by those involved in marathon.

Marathon related kidney damage may be caused by rise in runners body temperature and dehydration which prevents blood flow to kidney. This last for two days because the kidney will recover after the marathon.

Whole body vibration therapy may replace regular exercise

Whole body vibration therapy WBVT is a passive form of exercise when something or machine is being used on a person rather than normal activities like walking and running.

WBVT users stand, sit or lay on a machine that vibrates and this process sends energy to the body by contracting and relaxing the muscle several times during the vibration.

WBVT is as good as exercise, it enhances muscle mass and insulin sensitivity in people that use it regularly. It is a useful therapy to combat metabolic dysfunction in people with morbid obesity.
