N2  -  Summary. Background. Winter training is pivotal for enhancing fitness and skills in female field hockey players but also brings physical and mental demands. Research on tailored nutritional support for these athletes remains limited. Methods. Twenty-five female field hockey players (average age 22.6 years) from Sichuan were randomly divided into an intervention group (n = 13) receiving personalized supplements including zinc and magnesium multi-vitamin sports nutrition powder, endurance sugar pump, testosterone synthesis pump, and melatonin tablets daily during the 8-week winter training, and a control group (n = 12) on their regular diet. Results. Creatine kinase levels rose initially in the intervention group but declined significantly from week four to eight compared to baseline, contrasting with the control group’s steady increase (p < 0.001). The intervention group also showed lower blood urea in weeks seven and eight, higher testosterone in weeks five, seven, and eight, and lower cortisol from weeks five to eight compared to the control group. Hemoglobin was higher in the intervention group in weeks four, seven, and eight, fatigue indices were lower in weeks five and eight, and sleep quality was better in week eight (p < 0.05). Conclusion. Personalized nutritional supplements effectively improved key physiological and biochemical indicators, reduced fatigue, and enhanced sleep quality in female field hockey players during their winter training, thereby enhancing training adaptability and competitive performance.
