Rhodiola Rosea, is an adaptogen plant which has been reported to promote fatty acids utilisation, to ameliorate antioxidant function, and to improve body resistance to physical strenuous efforts. The purpose of the present study was to investigate the effects on physical performance as well as on the redox status of a chronic Rhodiola Rosea supplementation in a group of competitive athletes during endurance exercise.
Following a chronic supplementation with Rhodiola Rosea for 4 weeks, 14 trained male athletes underwent a cardio-pulmonary exhaustion test and blood samples to evaluate their antioxidant status and other biochemical parameters. These data were compared with those coming from the same athletes after an intake of placebo.
The evaluation of physical performance parameters showed that HR Max, Borg Scale level, VO(2) max and duration of the test were essentially unaffected by Rhodiola Rosea assumption. On the contrary, Rhodiola Rosea intake reduced, in a statistically significative manner, plasma free fatty acids levels. No effect on blood glucose was found. Blood antioxidant status and inflammatory parameters resulted unaffected by Rhodiola Rosea supplementation. Blood lactate and plasma creatine kinase levels were found significantly lower (P<0.05) in Rhodiola Rosea treated subjects when compared to the placebo treated group.
Chronic Rhodiola Rosea supplementation is able to reduce both lactate levels and parameters of skeletal muscle damage after an exhaustive exercise session. Moreover this supplementation seems to ameliorate fatty acid consumption. Taken together those observation confirm that Rhodiola Rosea may increase the adaptogen ability to physical exercise.
红景天是一种适应原植物，据报道它能促进脂肪酸利用、改善抗氧化功能并提高身体对剧烈体力活动的抵抗力。本研究的目的是调查在耐力运动期间，长期补充红景天对一组竞技运动员的身体表现以及氧化还原状态的影响。
在长期补充红景天4周后，14名受过训练的男性运动员进行了心肺耐力测试，并采集血样以评估他们的抗氧化状态和其他生化参数。这些数据与服用安慰剂后的同一组运动员的数据进行比较。
身体表现参数评估显示，最大心率、博格量表水平、最大摄氧量和测试持续时间基本上不受红景天摄入的影响。相反，红景天的摄入以具有统计学意义的方式降低了血浆游离脂肪酸水平。未发现对血糖有影响。血液抗氧化状态和炎症参数不受红景天补充的影响。与安慰剂治疗组相比，红景天治疗组的血液乳酸和血浆肌酸激酶水平显著降低（P<0.05）。
长期补充红景天能够在力竭运动后降低乳酸水平和骨骼肌损伤参数。此外，这种补充似乎能改善脂肪酸消耗。综合这些观察结果证实，红景天可能增强对体育锻炼的适应原能力。
