Sports Nutrition RSS Feed- Oral Rg1 supplementation strengthens antioxidant
defense system against exercise-induced oxidative
stress in rat skeletal muscles May 18, 2012Background: Previous studies reported divergent results on nutraceutical actions and free radicalscavenging capability of ginseng extracts. Variations in ginsenoside profile of ginseng due todifferent soil and cultivating season may contribute to the inconsistency. To circumvent thisdrawback, we assessed the effect of major ginsenoside-Rg1 (Rg1) on skeletal […]
- Impact of an exercise program on acylcarnitines in obesity: a prospective controlled study May 10, 2012Conclusion: In conclusion, a controlled 10-week AE program improved beta-oxidation by reducing long-chain ACs. This finding highlights the importance that AE might have in avoiding or reverting lipotoxicity, and in consequence, improving insulin sensitivity and pancreatic beta cell functional reserve. (Source: Journal of the International Society of Sports N […]
- Dose response effects of a caffeine-containing energy
drink on muscle performance: a repeated measures
design May 8, 2012Background: Energy drinks have become the most used caffeine-containing beverages in the sport setting.The aim of this study was to determine the effects of two doses of a caffeine-containingenergy drink on muscle performance during upper- and lower-body power-load tests. Methods: In a randomized order, twelve active participants ingested 1 and 3 mg of caffe […]
- Exercise-induced muscle damage is reduced in resistance-trained males by branched chain amino acids: a randomized, double-blind, placebo controlled study May 8, 2012Conclusion: The present study has shown that BCAA administered before and following damagingresistance exercise reduces indices of muscle damage and accelerates recovery in resistancetrainedmales. It seems likely that BCAA provided greater bioavailablity of substrate toimprove protein synthesis and thereby the extent of secondary muscle damage associatedwith […]
- Effect of New Zealand blueberry consumption on recovery from eccentric exercise-induced muscle damage May 7, 2012Conclusions: This study demonstrates that the ingestion of a blueberry smoothie prior to and after EIMDaccelerates recovery of muscle peak isometric strength. This effect, although independent ofthe beverage's inherent antioxidant capacity, appears to involve an up-regulation of adaptiveprocesses, i.e. endogenous antioxidant processes, activated by the […]
- Adenosine 5' -triphosphate (ATP) supplements are
not orally bioavailable: a randomized, placebocontrolled
cross-over trial in healthy humans April 17, 2012Conclusions: A single dose of orally administered ATP is not bioavailable, and this may explain whyseveral studies did not find ergogenic effects of oral ATP supplementation. On the otherhand, increases in uric acid after release of ATP in the proximal part of the small intestinesuggest that ATP or one of its metabolites is absorbed and metabolized. Uric aci […]
- Acute L-arginine alpha ketoglutarate supplementation fails to improve muscular performance in resistance trained and untrained men April 17, 2012Conclusion: The results from our study indicate that acute AAKG supplementation provides no ergogenic benefit on 1RM or TLV as measured by the standard barbell bench press and leg press, regardless of the subjects' training status. (Source: Journal of the International Society of Sports Nutrition) […]
- Improved cycling performance with ingestion of hydrolyzed marine protein depends on performance level April 10, 2012Background: The effect on performance of protein ingestion during or after exercise is not clear. This has largely been attributed to the utilization of different scientific protocols and the neglection of accounting for factors such as differences in physical and chemical properties of protein supplements and differences in athletic performance level. Metho […]
- No effect of creatine supplementation on oxidative stress and cardiovascular parameters in spontaneously hypertensive rats April 5, 2012Conclusions: Using a well-known experimental model of systemic arterial hypertension, this study did not confirm the possible therapeutic effects of Cr supplementation on oxidative stress and cardiovascular dysfunction associated with arterial hypertension. (Source: Journal of the International Society of Sports Nutrition) […]
- Effect of betaine supplementation on cycling sprint performance April 3, 2012PurposeTo examine the effect of betaine supplementation on cycling sprint performance. Methods: Sixteen recreationally active subjects (7 females and 9 males) completed three sprint tests, each consisting of four 12 sec efforts against a resistance equal to 5.5% of body weight; efforts were separated by 2.5 min of cycling at zero resistance. Test one establi […]
