rhodiola-rosea-fatigue

この研究の注釈：

200mg of rhodiola extract (300-1000mg root equivalent) twice daily for 4 weeks in persons with life and work-related stress was greatly able to reduce dysfunction and fatigue associated with stress in a time-dependent manner. Significant improvements were noted in social and work function secondary to reduced fatigue and improved mood.

20 days of rhodiola supplementation during examination periods for students (100mg SHR-5) was able to improve neuromotoric fitness (accuracy of maze drawing test), fatigue, and well being relative to placebo. Exam scores were 8.4% higher in the rhodiola group relative to placebo.

In military cadets performing regular military night duties, 5 days of supplementation of rhodiola (370 or 555mg of SHR-5) was able to significantly reduce total fatigue and improve well being when measured 2 hours after supplement ingestion and again at the end of the trial. Capacity for mental work significantly increased relative to placebo.

A study of nursing students given a capsule containing 364mg rhodiola rosea (2.8% total rosavins) upon waking with an optional half dose (184mg) four hours later daily for 42 days noted that supplementation was associated with a worsening of fatigue scores as assessed by RAND-36 and VAS-F on day 42. No changes were observed on the MYMOP measurement and supplementation was well tolerated.

This negative effect manifested on day 42, with all other weekly measurements showing no significant differences between groups.

この研究の注釈：

Analyzed 11 studies on performance; 4 on mental and 6 on physical.

Most consistent benefits seen were with time to exhaustion (theorized to be from reducing the perception of tiredness) in physical activity, and increased mental perfomance under periods of stress.

この研究の注釈：

In healthy and otherwise active (but not trained) individuals given an acute dose of 100mg rhodiola (3% rosavins and 1% salidroside) or 4 weeks of supplementation noted an improvement in time to exhaustion and VO2 max with no significant influence on power output. Attention and reaction time were unaffected in this study,

この研究の注釈：

In otherwise healthy physicians, supplementation of rhodiola at 170mg (4.5mg salidroside) for 2 weeks (double blind crossover) was significantly antifatigue as assessed by a total fatigue index and was able to improve performance on work-related tasks by approximately 20%

この研究の注釈：

144mg rhodiola (SHR-5) with 2.3% salidroside was able to reduce fatigue, but not stressed, in a cohort of otherwise healthy persons after 1 week of supplementation.
