摘要
背景介绍红景天提取物据称可提高身体机能,增强抗压能力。红景天苷被认为是红景天具有增强体力作用的主要成分之一。然而,蔷薇萃取物中的水杨甙含量相对较低,而且蔷薇的栽培具有挑战性,因为它主要生长在高海拔、寒冷的地区。此外,由于玫瑰茄越来越受欢迎,其保护问题也备受关注。这项探索性研究的目的是评估补充纯生物合成的蔷薇水杨甙对健康活跃的年轻人的运动表现、情绪状态以及炎症和肌肉损伤指标的短期影响:50名参与者(30名男性,20名女性;21±4岁;173±8厘米;74±13公斤)被随机分配到补充丹皮苷(60毫克/天,16天)或安慰剂的方案中,并接受峰值摄氧量(VO2峰值)、间歇性耗竭时间(TTE)和局部肌肉耐力评估,以及使用情绪状态档案(POMS)进行的情绪状态评估。对血液样本进行了红细胞生成素、肌红蛋白、肌酸激酶-MM 和 C 反应蛋白分析:结果:与基线值相比,补充盐肤木苷提高了高强度间歇运动时的总体预测摄氧量百分比(p p = 0.02),而盐肤木苷组没有观察到统计学意义上的显著增加,这表明运动引起的肌肉损伤有所减轻。安慰剂组在 TTE 测试中进行的间歇次数减少(p = 0.03),友好度降低(p p 结论:补充盐甙可能会增强肌肉的耐受性:补充水杨甙可提高氧气利用率,减轻运动引起的肌肉损伤和疲劳,因此有必要对其长期效果和作为活跃人群适应原的潜力进行进一步研究。
Salidroside and exercise performance in healthy active young adults - an exploratory, randomized, double-blind, placebo-controlled study.
Background: Rhodiola rosea extract is purported to improve physical performance and support resilience to stress. Salidroside is considered to be one of the main constituents responsible for the ergogenic actions of R. rosea. However, R. rosea extract contains relatively little salidroside and cultivation of R. rosea is challenging as it is mainly found in high-altitude, cold regions. Additionally, the R. rosea plant is subject to conservation concerns because of its growing popularity. The purpose of this exploratory study was to evaluate the short-term effects of pure, biosynthetic salidroside supplementation on exercise performance, mood state, and markers of inflammation and muscle damage in healthy active young adults.
Methods: Fifty participants (30 M, 20F; 21 ± 4 yrs; 173 ± 8 cm; 74 ± 13 kg) were randomly assigned to either salidroside (60 mg/day for 16 days) or placebo supplementation and underwent peak oxygen uptake (VO2 peak), intermittent time-to-exhaustion (TTE), and local muscular endurance assessments, along with mood state evaluations using the Profile of Mood States (POMS). Blood samples were analyzed for erythropoietin, myoglobin, creatine kinase-MM, and C-reactive protein.
Results: Salidroside supplementation enhanced overall percent predicted oxygen uptake during high-intensity intermittent exercise (p < 0.01). An increase in serum myoglobin was observed 24 hours following exercise in the placebo group (p = 0.02) compared with baseline whereas no statistically significant increase was observed for the salidroside group indicating reduced exercise-induced muscle damage. Placebo group experienced a decrease in number of intervals performed during the TTE test (p = 0.03), and a decrease in friendliness (p < 0.01) and an increase in fatigue-inertia (p < 0.01) as reported by POMS. The salidroside group exhibited stable mood states and maintained performance levels during the time-to-exhaustion test.
Conclusion: Salidroside supplementation may enhance oxygen utilization and mitigate exercise-induced muscle damage and fatigue, warranting further research on its long-term effects and potential as an adaptogen for active individuals.
期刊介绍:
Journal of the International Society of Sports Nutrition (JISSN) focuses on the acute and chronic effects of sports nutrition and supplementation strategies on body composition, physical performance and metabolism. JISSN is aimed at researchers and sport enthusiasts focused on delivering knowledge on exercise and nutrition on health, disease, rehabilitation, training, and performance. The journal provides a platform on which readers can determine nutritional strategies that may enhance exercise and/or training adaptations leading to improved health and performance.
