The purpose of this study was to determine if Omega 3 Chia seed loading is a viable option for enhancing sports performance in events lasting >90 minutes and allow athletes to decrease their dietary intake of sugar while increasing their intake of Omega 3 fatty acids. It has been well documented that a high dietary carbohydrate (CHO) intake for several days before competition is known to increase muscle glycogen stores resulting in performance improvements in events lasting >90 minutes. This study compared performance testing results between 2 different CHO-loading treatments. The traditional CHO-loading treatment served as the control (100% cals from Gatorade). The Omega 3 Chia drink (50% of calories from Greens Plus Omega 3 Chia seeds, 50% Gatorade) served as the Omega 3 Chia loading drink. Both CHO-loading treatments were based on the subject's body weight and were thus isocaloric. Six highly trained male subjects V(O2)max 47.8-84.2 ml · kg(-1); mean (SD) of V(O2)max 70.3 ml · kg(-1) (13.3) performed a 1-hour run at ∼65% of their V(O2)max on a treadmill, followed by a 10k time trial on a track. There were 2 trials in a crossover counterbalanced repeated-measures design with a 2-week washout between testing sessions to allow the participants to recover from the intense exercise and any effects of the treatment. There was no statistical difference (p = 0.83) between Omega 3 Chia loading (mean 10k time = 37 minutes 49 seconds) and CHO loading (mean = 37 minutes 43 seconds). Under our conditions, Omega 3 Chia loading appears a viable option for enhancing performance for endurance events lasting >90 minutes and allows athletes to decrease their dietary intake of sugar while increasing their intake of Omega 3 fatty acids but offered no performance advantages.
本研究旨在确定欧米茄 3 奇亚籽加载是否是一种可行的选择，以增强持续时间超过 90 分钟的运动表现，并允许运动员减少糖的饮食摄入，同时增加欧米茄 3 脂肪酸的摄入。已经有充分的文献记载，在比赛前几天高碳水化合物（CHO）的饮食摄入已知会增加肌肉糖原储存，从而提高持续时间超过 90 分钟的运动表现。本研究比较了两种不同 CHO 加载处理之间的性能测试结果。传统的 CHO 加载处理作为对照（100%卡路里来自佳得乐）。欧米茄 3 奇亚饮料（50%卡路里来自 Greens Plus 欧米茄 3 奇亚籽，50%佳得乐）作为欧米茄 3 奇亚加载饮料。两种 CHO 加载处理均基于受试者的体重，因此是等热量的。六名经过高度训练的男性受试者 V(O2)max 为 47.8-84.2 ml · kg(-1)；V(O2)max 的平均值（SD）为 70.3 ml · kg(-1)（13.3）在跑步机上以约 65%的 V(O2)max 进行 1 小时跑步，然后在赛道上进行 10k 计时赛。在交叉平衡重复测量设计中有 2 次试验，两次测试之间有 2 周的洗脱期，以允许参与者从剧烈运动和治疗的任何影响中恢复过来。在我们的条件下，欧米茄 3 奇亚加载（平均 10k 时间= 37 分 49 秒）和 CHO 加载（平均= 37 分 43 秒）之间没有统计学差异（p = 0.83）。在我们的条件下，欧米茄 3 奇亚加载似乎是一种可行的选择，可以增强持续时间超过 90 分钟的耐力运动表现，并允许运动员减少糖的饮食摄入，同时增加欧米茄 3 脂肪酸的摄入，但没有提供性能优势。
