Elliptical Trainer Information About Knee Injury
Elliptical Trainers and Treadmills are great pieces of exercise equipment for getting in shape. Recently elliptical trainers have begun to eclipse treadmills in popularity. As elliptical trainer information becomes more and more available to the general public this trend should continue. The ability of elliptical trainers to prevent and protect joints, muscle and bones is a major advantage. As the population gets older and the baby boomers enter retirement, elliptical trainers will become increasingly more popular. Elliptical machines will allow intense full body exercise routines to be conducted with relative safety.Treadmills have pretty much been the main piece of fitness equipment found local gyms and fitness centers. However, my doctor recommends that I stay off them since my knee was scoped 5 years ago. We love doing our road work outdoors on natural surfaces, however, here in Southwest Florida with its high temperatures and humidity during summer, we prefer exercising in air conditioning. Exercise physiologists and doctors tell us that when you use a tread mill that is not perfectly adjusted, each time your foot strikes the belt it slides forward a small amount. It is this motion that causes knee injury. If you are over 150 lbs. and use the treadmill for running it can be very noticeable and sometimes uncomfortable. Many times my knees will ache after just two miles of a light jog on a treadmill. I recently talked to an exercise equipment repair technician who told me that about 80% of all treadmills are not adjusted properly. The main cause is that it is expensive to properly maintain treadmills and that they can easily become out of tune. I have on more that one occasion tried more than one treadmill at our local fitness center before I found one that did not have a pronounced belt slip.Elliptical trainers are easier on our knees due to the greatly reduced impact. They also do not have the belt slip problems that hurt our knees. Some people describe running on an elliptical trainer to something like running on air. It does take a little getting used to the change in motion but it does allow you to do a good aerobic workout when your knees are sore. In fact some physical therapist use elliptical trainers as part of their recovery programs. I have also noticed that I can exercise longer on my sore damaged knee on an elliptical trainer than I can on a treadmill. Many quality elliptical trainers have the ability to change the angle or slope of the elliptical motion. This has a major benefit in that it will allow you to change the shape of the stroke to eliminate pain and discomfort during your exercise routine. Several times when my knee would start to tighten up I have been able to complete my exercise program by simply changing the angle or slope on the elliptical machine. You should never try to force a joint problem through a painful
What are some facts about Solar Eclipse?

Question by Domo: What are some facts about Solar Eclipse?

Answer by LydzyHmm, I shall use all my skills here of Solar Eclipse Knowledge, it'll be a lot of typing:):
Solar eclipse -- the passage of the new Moon directly between the Sun and the Earth when the Moon's shadow is cast upon the Earth. The Sun appears in the sky either partially or totally covered by the Moon. Unfortunately, not every eclipse of the Sun is a total eclipse. Sometimes, the Moon is too small to cover the entire Sun's disk.
Earth's total solar eclipse is unique in the solar system. Why? The sun is about 400 times the size of the moon and it is also about 400 times further away from the earth than the moon is.
An eclipse of the Sun (or solar eclipse) can only occur at New Moon when the Moon passes between Earth and Sun.
Permanent eye damage can result from looking at the disk of the Sun directly, or through a camera viewfinder, or with binoculars or a telescope even when only a thin crescent of the Sun or Baily's Beads remain.
The 1 percent of the Sun's surface still visible is about 10,000 times brighter than the full moon. Staring at the Sun under such circumstances is like using a magnifying glass to focus sunlight onto tinder.
Once the Sun is entirely eclipsed, however, its bright surface is hidden from view and it is completely safe to look directly at the totally eclipsed Sun without any filters. In fact, it is one of the greatest sights in nature.

Annular Solar Eclipse seen from Chiba, Japan May 21. 2012. Filmed with a Canon iVIS HF21 without filter as the clouds worked well enough for that role. 金環日食Below I will explain to you with numbers that are easy to comprehend, but first, here are some facts about the sun, the earth, and the moon and their actual sizes and distances between each other: The Sun is almost perfectly spherical and has a diameter of about 1392000 km, about 109 times that of Earth. The Earth's diameter is about 12700 km. The Moon's diameter is about 1/4 that of Earth, about 3175 km. The distance between the Sun and the Earth varies between 152 million km (around July) and 147 million km (around January). For simplicity we can say that the distance is on average 150 million km. The distance between the Moon and Earth varies between 356400km and 406700km, on average about 380000 km. Now, to put this into sizes and distances you and I are able to comprehend, let's scale everything down: Imagine a ball which has a diameter of 1 meter. This would be our Sun. About 108 meters away we will find our Earth which would be the size of a marble with a diameter slightly less than 1 cm (about 9.1mm). Finally, our Moon would be like a very small pea with a diameter
