Increasingly, the former seems to be the case, with When the customer balks at the price or seems hesitant, direct sales persons are known to cut a thousand dollars from the price, add a free VCR or even in some cases a trip to Hawaii. While there are other known triggers, this may be the most pernicious one - and may even be secretly promoted by your insurance company. Tai chi supporters say it can, and as a senior health writer for The New York Times found, this Most in-home "whole house" salespersons will usually play fast and loose with the word "purifier" when discussing this multi-thousand dollar investment with him in your living room. Most whole house water sales companies offer an under-sink Reverse Osmosis filtration system go HERE for more details on this type of system or HERE to compare reverse osmosis to other types of home drinking water appliances.

The drinking water appliance can also be other types of water treatment devices, primary steam distillers, providing much higher water purity, removal of bacteria as well as more thorough and long-lasting protection against the consumption of the copious amount of sodium being discharged into the home water system. We will discuss these other drinking water appliance options below. Who is selling these "whole house" water systems? In the last years, the market for home water softeners has diminished dramatically for both environmental and economic reasons, leaving these water softening companies with a basic survival problem.

Simultaneously, drinking water quality throughout the country began a downward trend, opening the market for home water filtration and purification systems. In this metamorphosis from water softening company to "whole house" water treatment specialist, they also decided to employ high powered, in-home direct sales personnel who would go home to home and now sell equipment that originally would cost only a few hundred dollars as most, now for several thousand dollars.

So, if you have had a phone call from a friendly sounding person offering to come to your home to do a "water test", it is simply the precursor for a grueling, multiple-hour, high pressure in home presentation by a pretty slick salesperson, attempting to extract thousands of dollars for equipment that can be purchased at local retail stores for thousands of dollars less.

Many of the "whole house" water sales organizations are legitimate members of your local business community. Others who may call on you at random, for the "free water test" or other inducement, may simply be what are called "boiler rooms": See the following discussion. Is this "Whole House" water treatment and filtration equipment really necessary?

It depends on two things: Is the Water Conditioner Necessary? However, when water has a hardness exceeding "grains", a water conditioner makes a significant difference. Less than 10 grains of "hardness" is usually acceptable and does not cause significant degradation of household utility water uses. The salesperson who may come to your home or who perhaps has already visited you will try to make a big deal out of a simple water test when that test shows more than a couple of grains of hardness.

In reality, water with grains of hardness would be water most housewives would give their left arm for in many parts of the country. From grains it may be of significant benefit. Greater than 15 grains means that you will notice a significant difference in utility water conditions with a water conditioner and you will also notice new smile on your wife's face because of easier water conditions in the parts of the house normally plagued with scale or spotting.

Water with greater than grains of hardness usually means that the standard water conditioner which the "whole house" water salesperson is promoting may not be adequate for your needs. Is the Drinking Water Appliance Necessary? The need for the drinking water appliance portion of the "whole house" water system is equally important to evaluate, as well as the specific type of water treatment process being used by the appliance being offered.

This need is highly dependent on local water conditions and your family's commitment to the need for better water as part of better nutrition and health for the family. Most whole house water sales companies offer an under-sink Reverse Osmosis filtration system go HERE for more details on this type of system or HERE to compare reverse osmosis to other types of home drinking water appliances. In short, reverse osmosis is a "water filtration" system which removes taste, odor and a portion of the dissolved minerals present in the incoming water.

The unit fits under the kitchen sink and is connected to a separate faucet on the sink top as well as the nearby refrigerator if it makes cold water and ice from the house water supply. Reverse osmosis is not a "water purifier", simply meaning that it does not remove or eliminate biological problems such as bacteria and other micro-organisms that may reside in the incoming water and immune to chlorine or other water treatment processes or from the house or water system plumbing.

Most in-home "whole house" salespersons will usually play fast and loose with the word "purifier" when discussing this multi-thousand dollar investment with him in your living room.

The word "purification" strictly means the destruction or elimination of bacteria from a water supply; something reverse osmosis does not do. Therefore, the first issue you face is: Or is it likely a combination of both? What they found was that both the high-fat and high-carbohydrate groups had similar gene expression.

Work capacity during exercise is something else which must be taken into consideration. The exercise capacity when in a low-carbohydrate state is diminished, which could potentially compromise high intensity planned training sessions.

If you are not able to complete the planned training sessions, this could potentially hamper the long term training and competition goals. This lends into the periodization model, whereby we can undertake planned low load sessions with lower carbohydrate availability, while ensuring that planned high intensity sessions are undertaken with high carbohydrate availability.

In addition to the reduced work capacity, potential reduction in muscle protein synthesis and increase in PDK4, we must also consider the effects on the immune system. High intensity training can have immunosuppressive effects, which may be exacerbated in periods of low carbohydrate availability, however, further research is required to fully elucidate this. Another thing to note is, that while not all training studies have shown a long term performance benefit, none have shown a decrement in performance.

Hopefully by now I have explained the why and the how of carbohydrate periodization. If you look at the Impey et al. Athletes are loaded with carbohydrate prior to, and during, high intensity sessions. Then in the evening of one of these recovery days, they will begin consuming carbohydrate again in preparation for another intense session coming the following day.

This is where the art of performance nutrition comes into play, as there are currently no set guidelines for what represented high, moderate or low, and this will likely change with regard to the individual and the type of training undertaken. Running is another sport where this could prove advantageous. As I mentioned earlier, many runners now undertaken a morning run not very intense, light pace and will typically perform intervals on some evenings.

Usually there is at least 1 long run per week. Combat sports are another potential benefactor of carbohydrate periodization. Carbohydrate restriction is typically associated with energy restriction, which combat sport athletes will be undertaking during a fight camp in order to make weight. Due to the schedule of fighters training, there will likely be scope to implement some carbohydrate-restricted sessions, which may also be an easy way to manipulate the energy intake of the athlete.

Even team sports may benefit from such an approach. Different training days for different team sports typically have differing demands. In this sense, you may periodize the carbohydrate on a day-by-day basis as opposed to meal-by-meal with the above examples. Recovery days and technical days may be undertaken with low and moderate carbohydrate intakes, while intense training days, pre-match, match day and the day after a match may all be high carbohydrate days.

Hopefully readers understand a little bit more about carbohydrate periodization and fueling the work required now and may be able to implement its use in practice. The concept of altering substrate availability on a day-by-day, meal-by-meal basis, to promote endurance training adaptations. He is currently completing his MSc in Sport Nutrition at Liverpool John Moores University, where he is also working as a Performance Nutritionist with various weight-making athletes ranging from combat sports, jockeys, powerlifters and formula e-racing.
