Effect of Eleutherococcus senticosus on submaximal and maximal exercise performance

Abstract

We investigated the effect of Eleutherococcus senticosus Maxim L (ESML) on performance during submaximal and maximal aerobic exercise. Twenty highly trained distance runners randomly assigned in matched pairs to either an experimental (ESML) or placebo (PL) group, participated in an 8-wk double-blind study during which they completed five trails of a 10-min treadmill run at their 10 km (10K) race pace and a maximal treadmill test (T(max)). Following a baseline trail, ESML and PL consumed, respectively, 3.4 ml of ESML extract or placebo daily for 6 wk. Subjects were tested every 2 wk during supplementation and 2 wk following withdrawal. Heart rate (HR), oxygen consumption (VO2), expired minute volume (VE), ventilatory equivalent for oxygen (VE/VO2), respiratory exchange ratio (RER), and rating of perceived exertion (RPE) were measured during the 10K and T(max) tests. Resting, post-10K and post-T(max) blood samples were analyzed for serum lactate. No significant differences were observed between ESML and PL for: HR, VO2, VE, VE/VO2, RER, or RPE; T(max) time to exhaustion; or serum lactate. The data do not support an ergogenic effect of ESML supplementation on selected metabolic, performance, or psychologic parameters associated with submaximal and maximal aerobic exercise tasks.

Ginseng Supplementation Does Not Enhance Healthy Young Adults’ Peak Aerobic Exercise Performance

“…Morris, Jacobs, and Klugerman [9] found no significant effect after 7 days of ginseng or placebo ingestion on a pedal to exhaustion bicycle test. Distance runners have also showed no effect with ginseng administration [10,11] (Table 3). …”

Dietary supplementation with Acanthopanax senticosus extract enhances gut health in weanling piglets

“…Recent studies have shown that AS plays a role in enhancing immunity, antibiosis, antioxidation (Yang et al, 2004) and in reducing many kinds of stress (Gaffney et al, 2001) and fatigue (Dowling et al, 1996). We previously found that AS extract (ASE) as a dietary additive modified the cellular and humoral immune responses of weaned piglets by modulating the production of immunocytes, cytokines and antibodies (Kong et al, 2007b), and also enhanced digestion and the absorption of dietary AA in weaned piglets (Kong et al, accepted for publication).…”

Acanthopanax senticosus inhibits nitric oxide production in murine macrophages In Vitro and In Vivo

“…Siberian ginseng, Eleutherococcus senticosus) belongs to the family Araliaceae and is a 1.5-2.6 m high shrub found in China, Korea, Japan and Russian. In China and Russian, the root bark extract of this herb has been known for thousands of years as a remedy for psychophysical stress or fatigue (Brekhman and Dardymov, 1969;Brekhman and Kirillov, 1969;Dowling et al, 1996). The roots and stems of A. senticosus have been also used to treat chronic diseases, such as chronic renal failure, rheumatics, diabetes mellitus, chronic bronchitis, hypertension, gastric ulcer and ischemic heart diseases (Nishibe et al, 1990;Fujikawa et al, 1996;Davydov and Krikorian, 2000).…”
