| Abstract | ||||
| Research aims: This research aims to identify the effect of the use of oranges on: - Biochemical variables (Vitamin C or Acid Ascorbic- glutathione GSH- Vit B2- MDA) of swimming specialized students. - Improving the skill level of crawl stroke, backstroke and breaststroke swims (50 m timing- 50 m performance) and enduring swimming for 3 min for swimming specialized students. Research Methods: The researchers used the experimental method using measurements (pre -post) on two groups (experimental - group), in order to suit the nature of this research. Research Sample: The sample was selected in a purposive way from the students of the fourth year at the Faculty of Physical Education for Girls in Cairo for the academic year 2016-2017 specialized in swimming and their number was (14) students. The sample was divided into two equal groups, one of which is experimental that drinks orange juice as a catalyst for energy production 30 min before starting to practice swimming training according to the specialization requirements for the fourth and the other group is the controlled where the researchers applied the program only; each group contained (7) students. Orange juice: It is prepared by squeezing the orange fruit containing the peel (which contains the largest amount of vitamin C and antioxidants; the most important is flavonoids), filter it and drink half an hour before training. Conclusion: - There are statistically significant differences between the post measurements of the experimental and control groups in the level of some biochemical variables (vitamin C or ascorbic acid - glutathione GSH - Vit B2 – MDA) in favor of the experimental group. - There are statistically significant differences between the post measurements of the experimental and control groups in the digital level of crawl stroke, backstroke and breaststroke swims (50 m timing- 50 m performance) and enduring swimming for 3 min in favor of the experimental group. | ||||
