Brief Summary
The objective of this study is to evaluate the efficacy of physiological and biochemical monitoring along with nutritional support in improving the performance and well-being of female weightlifters during the critical weight reduction phase before competition. It also seeks to determine the safety and potential benefits of the personalized nutritional interventions. The primary questions this study aims to address are: Does personalized nutritional support, informed by physiological and biochemical monitoring, reduce the incidence of fatigue and improve sleep quality in female weightlifters during the pre-competition period? How do serum indicators change in response to the nutritional interventions, and what does this indicate about the athletes' health and performance? What are the perceived benefits and any potential adverse effects reported by the participants receiving the nutritional support? To assess the impact of the intervention, researchers will compare the outcomes of the experimental group, which receives the tailored nutritional support, to those of the control group, which follows standard practices without additional intervention. Participants will be required to: Consume the nutritional supplements or maintain their regular diet as assigned for the duration of the 1-month study. Attend scheduled visits to the research facility every two weeks for comprehensive health assessments, including blood tests for serum indicators and evaluations of fatigue levels and PSQI scores. Record their daily experiences, including dietary adherence, training intensity, perceived fatigue, sleep patterns, and any other relevant observations in a personal diary. By conducting this randomized controlled trial, the study will provide valuable insights into the role of targeted nutritional support in enhancing athletic performance and overall health during the demanding pre-competition weight reduction period.

Outcome Measures
Primary Outcomes (7)
Serum Testing: blood urea
Approximately 2 ml of fasting venous blood was taken from the participants' elbow. Beckman Coulter Automated Biochemical Analyzer (California, USA) was used to measure blood urea.
28 Days
Serum Testing: creatine kinase
Approximately 2 ml of fasting venous blood was taken from the participants' elbow. Beckman Coulter Automated Biochemical Analyzer (California, USA) was used to measure creatine kinase.
28 Days
Serum Testing: blood testosterone
Beckman Coulter Chemiluminescence Immunoassay Analyzer (California, USA) was used to measure blood testosterone.
28 Days
Serum Testing: cortisol
Beckman Coulter Chemiluminescence Immunoassay Analyzer (California, USA) was used to measure blood cortisol.
28 Days
Serum Testing: hemoglobin
HemoCue Hb 301 Hemoglobinometer (Sweden) was used to measure hemoglobin.
28 Days
Scale Testing: fatigue scores
Participants were requested to assess their level of fatigue using the Visual Analogue Scale (VAS) for Fatigue, a validated measurement tool. On the VAS, a 10 cm line is marked, where '0' cm represents no fatigue and '10' cm represents the most severe fatigue possible. Higher scores on this scale indicate a greater degree of fatigue, with lower scores reflecting less fatigue.
28 Days
Scale Testing: Pittsburgh Sleep Quality Index
The Pittsburgh Sleep Quality Index (PSQI) is a questionnaire used to assess the sleep quality of the subject over the past month, composed of 18 self-rated items forming 7 components, with a total score ranging from 0 to 21 points, the higher the score, the worse the sleep quality.
28 Days
Study Arms (2)
Control group
NO INTERVENTIONAll participants followed their coaches' regular training plans for daily training (actual pre-competition training environment), without altering their personal routines or lifestyle habits.
Experimental group
EXPERIMENTALParticipants in the experimental group received a four-week tailored nutrition program, developed by sports nutritionists based on athletes' biochemical profiles, body weight, training intensity, and dietary habits. The program included: Daily Dietary Logs: Monitoring food intake for immediate nutritional adjustments. Weekly Nutritional Consultations: Strategy refinement discussions with experts. Customized Nutritional Supplements: "Zinc Magnesium Multi-Vitamin Sports Nutrition Powder" was used to improve blood urea, cortisol, and hemoglobin levels, containing ingredients like rice bran lipid alcohol, magnesium, zinc, and B vitamins. Performance-Specific Supplements: "Endurance Sugar Pump" to lower creatine kinase levels during training and "Testosterone Synthesis Pump" to enhance testosterone, both by Weite Beijing Co., Ltd. Sleep Aid: "Melatonin Tablets" to ensure restful sleep, containing vitamin B6 and melatonin, produced by Dongli Beijing Co., Ltd.
Interventions
The control group maintained their regular diet and training without additional nutritional support.
