简要总结
This study investigates whether 8 weeks of post-training whey protein supplementation (30 g/day) affects serum mineral concentrations (calcium, phosphorus, magnesium, and iron) in elite endurance and power athletes during structured training.
详细描述
This is a 10-week non-randomized, open-label intervention study involving elite male track-and-field athletes aged 18-26 years. Participants are allocated into a whey protein supplementation group or a control group based on convenience allocation. The intervention consists of daily intake of 30 g whey protein following training sessions over 8 weeks. Blood samples are collected at baseline and post-intervention to assess serum calcium, phosphorus, magnesium, and iron levels. The study aims to differentiate supplementation effects from training-induced physiological changes.

结局指标
主要结局
serum mineral concentrations (Calcium, Phosphorus, Magnesium, Iron)
时间窗: Baseline (Week 1) and Post-Intervention (Week 10)
Serum concentrations of calcium, phosphorus, magnesium, and iron will be measured using standardized enzymatic and colorimetric assays from venous blood samples collected at rest. Measurements will be performed at baseline and after the intervention to assess changes associated with training and whey protein supplementation in elite athletes.
