Filter by:The purpose of the proposed project is to determine if short-term dietary supplementation of magnesium will improve performance during a series of lab-based exercise tests, will favorably modify the gut-microbiota, and will augment skeletal muscle mitochondrial function.
This study will employ a randomised, double-blind, placebo-controlled, independent groups experimental design. Submaximal, maximal and 5 km time trial running performance will be assessed before and after supplementation with haskap berry or a placebo.
Purpose: The aim of the present study was to evaluate potential beneficial effects of Kefir drink (Synbio Tech Inc., Kaohsiung City, Taiwan) on fatigue and ergogenic functions following physiological challenge. Methods: 16 male subjects, 8 in each group, were divided into two groups according to the principle of maximal oxygen uptake, which were (1) first-stage placebo and second-stage Kefir group (hereinafter referred to as group A). (2) The first phase of Kefeier, the second phase of the placebo group (hereinafter referred to as group B), after 4 weeks of supplementation, the performance and fatigue resistance tests were carried out in sequence, including: treadmill aerobic endurance exhaustion time, and fixation Exercise time and intensity challenge changes in blood lactate, blood urea nitrogen concentration and creatine kinase activity, as well as differences in body composition before and after supplementation. After the first phase of the test is completed, the four weeks of emptying are performed. And after adding the crossover sample, perform four weeks of supplementation and testing again.
We evaluated here the effects of 6-week intervention with herbal supplement on exercise performance outcomes and serum biomarkers of antioxidant status. In addition, we also assessed the long-term effects (6-month) of the intervention in elderly adults.
The purpose of this randomized, double-blind, crossover study is to investigate the effects of Bang® Keto Coffee on resting and post-exercise metabolism and muscular performance during lower body resistance exercise.
This study evaluates the effect of an open-label placebo intervention on cycling time-trial performance.
Cordyceps and Rhodiola are two common herbal supplements marketed and consumed as adaptogens to athletes with regard to enhanced performance. The effects of these supplements has been well studied in animals but whether or not the same effects translate to humans is still unclear. Thus, the primary purpose of this study is to determine whether combined supplementation of Rhodiola and Cordyceps, compared to Rhodiola alone and placebo, will demonstrate a greater improvement in oxygen consumption (ie. VO2 max).
In this randomized double-blind, placebo-controlled, crossover pilot trial, we evaluated the effects of 7-day H2 inhalation on exercise performance outcomes and serum hormonal and inflammation profiles in a cohort of young men and women.
Dietary nitrate, L-citrulline, epicatechin, vitamin C and glutathione have the potential to improve nitric oxide (NO) bioavailability, in humans, by influencing both the nitrate-nitrite-NO and NO synthase-dependent pathways, and the storage of NO. The study is designed to assess the efficacy of a newly developed product containing a mixture of these compounds. Specifically, the study will assess if the product is capable of increasing NO bioavailability and if this results in positive effects on exercise economy and intermittent exercise performance. These outcome measures have been chosen because they have previously been positively impacted by an increase in NO bioavailability.
Both acute ingestion (1-3 h) and chronic supplementation (3-30 days) with dietary nitrate has been shown to increase nitric oxide activity and, in some studies, to improve exercise economy, exercise tolerance, and endurance exercise performance. In addition, more recent evidence suggests that dietary nitrate has the potential to enhance team-sport-specific high-intensity intermittent exercise performance. Indeed, chronic dietary nitrate supplementation (2-6 days) has been reported to increase the distance covered before exhaustion during the Yo-Yo intermittent recovery level 1 test, a well-established and ecologically valid test widely used to mimic the high-intensity running bouts of soccer match-play. However, while these findings suggest that nitrate may be an effective ergogenic aid for team-sport players when consumed daily, it is currently unclear if the improvement in team-sport specific intermittent exercise performance can be achieved following a single bolus of dietary nitrate. Given the increasing interest and use of dietary nitrate as an ergogenic aid by team-sport players, establishing the shortest period of supplementation required to elicit an ergogenic effect is important in order to guide athletes on optimal supplementation strategies. Given that a single bolus of dietary nitrate has previously been shown to improve exercise tolerance and endurance exercise performance, and an improved Yo-Yo IR1 performance has been observed after chronic nitrate supplementation, the investigator hypothesizes that acute (2 h) and short-term (4 days) nitrate supplementation will significantly elevate nitric oxide activity (measured as an increase in plasma nitrite concentration and skeletal muscle nitrate concentration) and improve performance during the Yo-Yo IR1 test (measured as an increased in distance covered (m) during the test at the point of volitional exhaustion) to a similar extent, when compared to a placebo.
