ABSTRACT
Introduction
A tennis match may last up to four hours with long intervals between moves of medium to high exercise intensity for 10 minutes and aerobic characteristic that requires specific sources of energy. Inappropriate diets can negatively impact sports performance and delay the recovery phase. Fortified wheat germ protein powder has the supplementation characteristics required in aerobic activities, although there are no practical studies on its impacts on the work performance of female tennis athletes.
Objective
Explore the influence of two weeks of training in a warm environment combined with nutritional intervention on the performance of female tennis players.
Methods
It was observed by testing the immunological indices of elite female tennis players while training their changes and their effects on nutritional intervention.
Results
The increase in serum CK activity was closely related to the amount of exercise. Many studies have shown that serum CK activity increased significantly after strenuous exercise, and the serum CK value of subjects in the test group was significantly lower than that of the control group, showing better adaptability to exercise. Compared with before the nutritional intervention, the athletes’ weight decreased slightly, and the body fat percentage decreased significantly after the nutritional intervention. Compared with before nutritional intervention, sugar and salt supplements in athletes were significantly increased (P<0.05). Sweating rate, hydration rate, and hydration/sudden rate were also significantly increased (P<0.05).
Conclusion
Strengthening wheat germ protein supplementation may improve the nutritional albumin level in female tennis players, manifested in blood levels and immune function performance. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.
