概括
运动员通过花生或碳水化合物零食的额外卡路里增加了瘦身量. 高碳水化合物零食导致总体体重增加比花生零食超过10周.
科学领域:
- 运动营养 运动营养
- 运动生理学 运动生理学
- 身体组成 身体构成
背景情况:
- 优化营养摄入对于运动员来说至关重要,以支持训练和表现.
- 了解不同宏观营养素来源对人体构成的影响对于有效的运动营养策略至关重要.
研究的目的:
- 为了比较基于花生和高碳水化合物的零食对运动员进行阻力训练的体重增加和身体组成的影响.
- 为了评估一个为期10周的饮食和运动计划,促进健康的体重增加.
主要方法:
- 19名男性和13名女性运动员被随机分配到两组.
- 一组每天从花生零食 (PNT) 获得500千卡,另一组从高碳水化合物零食 (CHO) 获得.
- 两组人都参加了监督的全身阻力训练 (RT),每周三次,持续10周. 使用双能X射线吸收计来评估身体成分.
主要成果:
- 在10周内,总体质量增加2.2公斤,瘦身量 (LBM) 增加1.5公斤.
- 与PNT组 (1.6公斤) 相比,CHO组的总体质量 (2.7公斤) 显著增加 (P=0.007).
- 在PNT和CHO组之间没有观察到LBM增长的显著差异.
结论:
- 增加卡路里摄入量 (每天500千卡) 的10周疗法与RT相结合,促进了运动员显著的体重增加,主要是LBM.
- 补充零食的宏观营养成分可能会影响体重增加策略的有效性.
- 在这种情况下,高碳水化合物零食可能比以花生为基础的零食更有效地增加总体体重.

The randomization process involves assigning study participants randomly to experimental or control groups based on their probability of being equally assigned. Randomization is meant to eliminate selection bias and balance known and unknown confounding factors so that the control group is similar to the treatment group as much as possible. A computer program and a random number generator can be used to assign participants to groups in a way that minimizes bias.

Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...
