Aerobic Exercise

Aerobic exercises refer to those physical exercises that we like to do most. They are not so tough to do. But it is only that we can do them for a long duration. The term aerobic is used to refer to oxygen because the energy is generated out of this exercise with the utilization of oxygen.

For example, running or walking is done for a long duration but we do not generally put a lot of effort to do them. Swimming and bicycling also come into this category. Now one can understand what is an aerobic exercise. The intensity of the exercise is moderate and done for a long duration.

Then what are the benefits of this type of exercise? It reduces the blood pressure and most important for adults and older people. Our muscles used for respiration get strength and improve our respiratory abilities. Reduce troubles associated with lungs. Easy breathing and pumping of the blood by heart becomes efficient. Red blood cells also increase as the oxygen is needed for this exercise.

Anaerobic exercise

Anaerobic exercise unlike aerobic exercise does not involve use of oxygen to generate energy. This type of exercises are used to develop muscles so that the person can do great in short duration and high intensity activities.

Aerobic exercises are generally running, walking, bicycling and swimming. These are done for longer durations of time with less effort compared with an anaerobic exercise. Oxygen is used up to produce energy in aerobic exercises. This has many long term health benefits.

Unlike aerobic exercise anaerobic exercises are not performed for long term benefits but for short intense bursts of energy needed by muscles for performing wonderful feats. Many athletes and bodybuilders resort to this type of exercises.

Strength training

Strength training is for doing physical exercises and has many health benefits. It involves use of heavy weights to oppose gravity or using elastic forces. This has several health benefits apart from increasing the size and strength of muscles.

Strength training is done initially by lifting as much weight as possible by a person. Then the muscles respond to grow larger and stronger. As the person repeats the process the muscles grow larger and he/she need to steadily increase the weights also. This is how the process expands muscles gain size and strength.

Strength training reduces the potential for injuries to the body. It improves cardiac functioning and thus reduces the chances of a heart attack. Bone, muscles and ligament get strength and grow over time. Cholesterol level also increases.

What Kind of Mysterious Bond Exists in Groups of Nanotubes?

There seems to a kind of binding and cooperative force that exists within groups of nanotubes. This is not the case with individual tubes. It is like the bond between groups of living beings. The relation binds them together. But what is it with nanotubes?

This mysterious force was observed when the nanotubes are tested for their fatigue. The nanotubes are compressed over and again. Every second for over 100 hours. But they found that the groups of nanotubes are regaining their original shape even after hundreds of thousands of repetitive compressions.

The researches found that when the nanotubes are compressed they become like zigzag tubes. They are actually getting compressed and the shape is modified under the application of pressure. But immediately after releasing the pressure they are able to regain their original shape exactly as they were before. This recovery from exhaustive fatigue has attracted lot of researches and has become an important property of nanotubes.

Now researchers think that this property can be used to create artificial muscles. Why because the muscles respond by expanding after a stimulus. This is rather a smooth motion than a jerky one unlike with electric motors or pneumatic devices. Thus nanotubes are found to be useful for building artificial muscles. They are like the intricate structures found in the human body.

The invention of nanotubes has been really intriguing as they are the most advanced technology available today.

The same is not applicable with individual nanotubes. The researchers found this fatigue recovery property only with large groups of nanotubes rather than individual nanotubes. They did not understand the reason for this. There seems to some kind of mysterious force that binds them and lets them cooperate under pressure.
