METHODS: Six male participants were recruited for a double-blinded, randomized crossover study with either dairy or soy milk provided post RET. Venous samples were collected before and after milk consumption across seven timepoints (0-120 minutes) where circulating sex hormones were analyzed. Two-way ANOVA analyses were applied for repeated measures for each hormone. The area under the curve (AUC) was also calculated between dairy and soy milk. Significance was set at p<0.05.
RESULTS: No significant differences were observed in acute circulating serum for free (p=0.95), % free (p=0.56), and total testosterone (p=0.88), progesterone (p=0.67), or estrogen (p=0.21) between milk conditions. Likewise, no significant differences in AUC were observed between any hormones.
CONCLUSIONS: These findings suggest that consumption of dairy milk and soy milk have comparable acute effects on circulating sex hormones following RET. Further investigations with expanded sample sizes are needed to strengthen and broaden these initial findings.
方法:招募六名男性参与者进行双盲,RET后提供了乳制品或豆浆的随机交叉研究。在分析循环性激素的七个时间点(0-120分钟)内,在牛奶消耗之前和之后收集静脉样品。对每种激素的重复测量应用双向ANOVA分析。还计算了乳品和豆奶之间的曲线下面积(AUC)。显著性设定为p<0.05。
结果:在无急性循环血清中没有观察到显著差异(p=0.95),%游离(p=0.56),和总睾酮(p=0.88),孕酮(p=0.67),或雌激素(p=0.21)之间的牛奶条件。同样,任何激素之间的AUC均未观察到显着差异。
结论:这些研究结果表明,食用牛奶和豆浆对RET后循环性激素具有相当的急性影响。需要扩大样本量的进一步调查,以加强和扩大这些初步发现。
