The 4 Most Common Attributes of a Quality TreadmillWritten by Aaron Co
Continued from page 1
The best way to know if a treadmill has a powerful motor is by running on it. Motors of quality treadmills should not have a hard time maintaining your pace. Your workouts should be smooth and lag free, even at top speed. The moment you feel motor is having a hard time, avoid buying that unit completely. It’s a headache waiting to happen. Low Noise Level Another attribute of a quality treadmill is noise level. If machine makes too much noise, it could be due to poor engineering. Generally, less noise a treadmill produces better its engineering, and better its quality. Long Warranties And finally, last attribute is warranty. Quality treadmills are usually backed wholeheartedly by company who made it. A typical quality treadmill warranty is at least a lifetime on frames, 2 years on parts and a year on labor/service. Warranties like these show that manufacturer is confident that their product is of high quality. Well, there you have it. Those are attributes of a quality treadmill. Let this article be a guide to you in your purchasing decisions.

Therefore, any substance that prevents oxidation of LDL is thought to be anti-atherogenic. Though animal-based proteins have traditionally been implicated as being pro-atherogenic, whey proteins appear to be an exception to rule. whey protein is made up of several minor and major fractions, such as beta-lactoglobulin, alpha-lactalbumin, albumin, lactoferrin and immunoglobulin. It was discovered that minor constituent responsible for ability of whey protein concentrate to prevent oxidation of LDL appears to be lactoferrin fraction of protein. 3. Lactoferrin In Whey When lactoferrin was removed from protein, ability of whey-protein concentrate to prevent LDL oxidation was greatly reduced, leading researchers to speculate, "Our results suggest that LF (lactoferrin) is main factor responsible for inhibitory effect of whey protein (on LDL) and it may function synergistically together with other factors in whey protein, for example, alpha-lactalbumin." Another study using rats examined effects of whey protein concentrate and casein on cholesterol and risk factors of heart disease. Though casein (another milk-based protein commonly used in research) is known to raise cholesterol in humans and animals, whey protein has opposite effect, leading researchers to note, "At high dietary protein level [300 gram per kilogram of feed] , whey protein significantly lowered plasma and liver cholesterol and also plasma triacylglycerols." 4. The cholesterol-lowering effects of whey protein concentrate in this study also was associated with a reduction in LDL cholesterol. Most interesting was fact that this effect on cholesterol was not seen when animals were fed amino acid mixtures that simulated whey protein, so it is clear that there are properties within whey that have these effects beyond that of its amino acid profile. Whey and Bone Growth Finally, whey protein appears to play a direct role in bone growth. Researchers found that rats fed whey protein concentrate showed increased bone strength and bone protein such as collagen. This discovery led researches to test whether or not whey protein directly stimulated osteoblast (bone cell) growth in vitro. Whey protein was found to stimulate, dose dependently, total protein synthesis, DNA content, and increased hydroxyproline contents of bone cells. 5. It should be noted that not all whey protein concentrates are created equal. Processing whey protein to remove lactose and fats without losing its biological activity takes special care by manufacturer. The protein must be processed under low temperature and low acid conditions so as not to "denature" protein. Maintaining natural state of protein is essential to its biological activity. These research findings, combined with previous decade of study on whey protein, should convince anyone that whey protein concentrate is truly life-extension protein. Higher Glutathione Levels and Whey A decade-and-a-half of findings on benefits of whey protein are far-reaching. Previous Studies Include The Following: Whey protein concentrate dramatically raises glutathione levels. Glutathione is an essential water-soluble antioxidant in body that protects cells and serves as a primary detoxifier of harmful compounds such as peroxides, heavy metals, carcinogens and other toxins. Glutathione also is intimately tied to immunity, and reduced glutathione levels have been associated with disease such as AIDS, atherosclerosis, Alzheimer's disease and Parkinson's disease, to name only a few. In fact, glutathione levels appear to be one way of modulating immunity. 6. Whey protein concentrate was found to consistently raise this extremely important immune stimulating antioxidant beyond that of any protein studied (including soy) to higher than normal levels in multiple animal studies. 7. A small pilot study with HIV-positive men who were fed whey protein concentrate found dramatic increases in glutathione levels of all study participants, with two out of three men reaching their ideal body weight. 8. In fact, there have been several U.S. and international patents granted for treatment of AIDS and improving immunity with whey protein concentrates.Whey protein improves immune function and fights infections. Animals fed whey protein concentrate consistently showed dramatic enhancement of both humoral and cellular immune response to a variety of immune challenges, such as salmonella, streptococcus pneumonia 9 and extreme cancer-causing chemicals. This effect on immunity was not seen with other proteins. So proof Whey protein concentrate fights cancer!!
