Abstract
The research aims to study the possibility of improving the recovery time of healthy university students after providing them with natural nutritional support.
Diet is directly related not only to physical condition but also to brain function and mental state. Whole body nutrition affects the production of neurotransmitters in the brain. A diet that does not have an adequate supply of protein, mineral nutrients, or vitamins may lead to a failure to form balanced numbers. inappropriately remove the neurotransmitters, which as a result may lead to an imbalance in neurotransmission.
The study was conducted on 20 ”male” students from the fourth year- Faculty of Science- Suez Canal University. The experimental treatments were performed as follows:
- The nutritional fortification was carried out with a source rich in (choline, zinc, and vitamin B12, which is (250 grams of the municipal liver) for each student daily for 4 weeks.
- Dietary intervention was carried out with a source rich in omega (130 grams of fava beans with one tablespoon of tahini + beans with one tablespoon of linseed oil + 50 grams of sesame candy) daily for 2 weeks.
- Fortified with a source of caffeine (a cup of coffee without adding any sweeteners or flavors) daily for two weeks.
- Supplementation with a source of ginger roots decoction (9 grams of ginger roots) daily for two weeks.
5.1 Results:
The practical experience: The experiment consisted of two parts:
- The first section:
The experiment was conducted on 20 male students, and they were randomly divided into two groups (experimental group, numbering 15 students), and (control group, numbering 5 students) daily for 4 weeks for the experimental group.
The proportion of choline, zinc, and vitamin B12 in the blood plasma was measured before and after for the two groups. The laboratory analyses showed that there were statistically significant differences between before and after the nutritional intervention when supported by (beef liver) at P>0.01 in the experimental group, and the results showed an improvement In the laboratory indicators resulting from the dietary intervention (beef liver) for each of (choline, zinc and vitamin B12):(67.96);(221.00) and (278.11) respectively at p>0.01, meanwhile, a negative association was also observed between the experimental group fortified with food (250 grams of the liver for 30 days) and the control group whose diet was not interfered with.
The return time was measured using 5 online tests of R.T. - pre and post for the control and experimental group. There were statistically significant differences at (P<0.01) Test-1 (0.977, 0.479), Test-2 (0.673, 0.472), Test-3 (0.988, 0.521), Test-4 (1.030, 0.474), and Test -5 (0.730, 0.478) for pre and post R.T.- tests compared to the control group.
- The second section:
The experimental group was divided into 3 subgroups, each of them 5 students (ginger, caffeine, omega) in addition to the control group.
Nutritional support for ginger was carried out using 9 grams of ginger root daily for two weeks, the nutritional support for caffeine was carried out using a cup of coffee without adding sweeteners or flavorings daily for two weeks, and a dietary intervention was carried out with a source rich in omega (130 grams of fava beans with a spoonful of tahini + one tablespoon of linseed oil + 50 grams of sesame candy) daily for 2 weeks.
It showed that there were statistically significant differences between the control group and the experimental groups, and one of the interesting results of this study is that the results of the analysed temporal movement were equal in tests 1, 2, and 4 after two weeks taking ginger and caffeine. While the caffeine results were faster and lower in test 3 and in test 5, ginger was faster and lower, and the results were as follows: in the first, third, and fifth tests, the results were equal between the caffeine group and the ginger group, respectively (0.309); (0.291); (0.306); (0.304); and (0.435), (0.427) at P>0.01).
In this study, the time taken to respond to the visual stimulus was Faster and lower when taking caffeine in the third test (0.300) and ginger in five test (0.336) at P>0.01. So, the best result was for the caffeine and ginger groups, followed by the omega group.
5.2 Conclusions:
The study concluded that the use of caffeine and ginger supplements improves reaction times in healthy students; and that students should consider taking caffeine and ginger supplements to improve attention, cognition, and response speed; Supplements containing caffeine and ginger may delay fatigue and improve cognitive performance.
from the results obtained and described in the previous chapter, we can conclude with some general recommendations and research recommendations:
1. Choline, zinc, and vitamin B12 have an effect on improving reaction time and blood analysis. Therefore, it is recommended to take it regularly in the daily diet.
2. A cup of light Turkish coffee as a source of caffeine improves the reaction time.
1.
3. A cup of ginger decoction as a source of gingerol, shogaol, and other active substances has the effect of improving the reaction time.
2.
4. Sesame contains a high percentage of omegas, so we recommend eating it to improve R.T., and Adding tahini and flaxseed oil to the diet as natural food sources of omegas to improve the reaction time.
5. Further studies are recommended on the effect of different types of vitamins and other nutritional supplements not included in the study to improve the reaction time.
