Explanations of scientific research

Though there is a set of scientific research, in most cases as a result of admissible results it is less, than could receive. Therefore estimating the results of researches bound to nutritional supplements it is important to find researches which answer, at least, some of criteria:

Double blind research: in this type of clinical trial, the participating subjects and researchers don't know when experimental drugs were given or the procedure to or is carried out later.

Placebo control: in this method of a research inactive additives (placebo) are given to group of examinees (control group), the second group (experimental group) was given the real additives (not placebo). As a result, the received results of two groups compare among themselves, regarding efficiency of treatment. When it is carried out as a double blind research, this type of a research is considered the gold standard of clinical tests.

Randomized controlled research: objects of research are chosen with the corresponding characteristics, then are in a random way distributed either in experimental, or in control group.

Clinical tests: pilot study with human subjects, the gold standard of clinical test, a double blind research, and placebo control which use in a casual order in experimental or control group.

Large number of subjects of a research: the more subjects pass clinical tests, the results of researches are more reliable.

Replicable researches: when results of a research were replicated reproduced), they will receive more influence.

Statistical value: The result is considered statistically significant when value of probability p-value less than 5% (0.05), it means that an outcome of casual result less than 5%. However we will receive more statistical result at 0.01 and 0.001.

Conclusion

For the last more than 100 years, it was revealed that many alimentary ingredients play an important role in the field of health care and welfare of productivity.

In 2012 100 years of official recognition of the term vitamin C conducting a way through discovery of vitamin of group B of Thiaminum which helps at avitaminosis symptoms (illness of the nervous system caused by a disadvantage of receiving Thiaminum from a food allowance) were executed. Soon, vitamin supplements received the way in track and field athletics, for improvement of productivity and endurance. In the 1920th years by scientists it was established that small consumption of carbohydrates was bound not only with disability to concentrate, and also caused premature fatigue of muscles and a disadvantage of force.

In Asian culture, on an extent more 4-ekh of thousands of years, ingredients from herbs, for strengthening of health and productivity were used. However all advantages of their reception aren't proved yet.

Unfortunately, many athletes don't pass a doping test, because of unreliable information about drug, and recalls of the additives available on the Internet showed that many products contain additives of steroids and stimulators which are forbidden for use in sport.

Use of a set of biological additives in a large number and in common, is unreal and it isn't necessary. Besides, for the last decades the set of clinical tests which show that good results can achieve is observed, accepting only several additional dietary supplements.

Fortunately, recently, producers check the production the independent third-party organizations more carefully to minimize risk from their use. Athletes are recommended to choose only the checked products, and also to warn the doctor or the dietarian before additive use.
