PURPOSE
This study compared the effect of a honey-sweetened beverage with those of a commercial sports drink and a placebo on performance and inflammatory response to a 90-min soccer simulation.
METHODS
Ten experienced male soccer players randomly performed 3 trials (honey [H], sports drink [S], and placebo [P]), consuming the beverage before and during halftime for a total of 1.0 g/kg carbohydrate for H and S. Performance measures included 5 sets (T1-T5) of a high-intensity run and agility and ball-shooting tests followed by a final progressive shuttle-run (PSR) test to exhaustion. Blood samples were drawn pretest, posttest (B2), and 1 hr posttest (B3) for markers of inflammation, oxygen radical absorbance capacity (ORAC), and hormone response.
RESULTS
T2-T5 were significantly slower than T1 (p < .05), and a decrease in PSR time was observed from baseline (-22.9%) for all treatments. No significant effect of the interventions was observed for any performance measures. Plasma IL-1ra levels increased posttest for all treatments (65.5% S, 63.9% P, and 25.8% H), but H was significantly less than S at posttest and P at B3. Other cytokines and ORAC increased at B2 (548% IL-6, 514% IL-10, 15% ORAC) with no difference by treatment.
CONCLUSION
Acute ingestion of honey and a carbohydrate sports drink before and during a soccer-simulation test did not improve performance, although honey attenuated a rise in IL-1ra. Ingestion of carbohydrate and/ or antioxidant-containing beverages at frequencies typical of a regulation match may not be beneficial for trained soccer players.
目的
本研究比较了蜂蜜甜味饮料、商业运动饮料和安慰剂对 90 分钟足球模拟比赛中运动员表现和炎症反应的影响。
方法
10 名经验丰富的男性足球运动员随机进行 3 次试验（蜂蜜组[H]、运动饮料组[S]和安慰剂组[P]），在赛前和中场休息时共摄入 1.0 克/千克碳水化合物，H 和 S 组均摄入碳水化合物。表现测量包括高强度跑步 5 组（T1-T5）、敏捷性和射门测试，然后进行最后一次渐进式穿梭跑（PSR）直至力竭。在测试前、后（B2）和后 1 小时（B3）采血，检测炎症标志物、氧自由基吸收能力（ORAC）和激素反应。
结果
T2-T5 明显慢于 T1（p<0.05），所有治疗组的 PSR 时间均较基线下降（-22.9%）。干预措施对任何表现测量均无显著影响。所有治疗组的血浆 IL-1ra 水平在测试后均升高（S 组 65.5%、P 组 63.9%、H 组 25.8%），但 H 组在测试后和 P 组在 B3 时显著低于 S 组。其他细胞因子和 ORAC 在 B2 时升高（IL-6 增加 548%、IL-10 增加 514%、ORAC 增加 15%），但治疗组之间无差异。
结论
在足球模拟测试前和测试中摄入蜂蜜和碳水化合物运动饮料并不能提高表现，尽管蜂蜜能降低 IL-1ra 的升高。在训练有素的足球运动员的典型比赛频率下摄入碳水化合物和/或含抗氧化剂的饮料可能对他们无益。
