Filter by:Guayusa extract is a caffeinated Amazonian 'super-leaf' belonging to the holly species that contains a very unique blend of polyphenol antioxidants and caffeine (~20% caffeine, 30% chlorogenic acids, 5% catechins). It is also remarkably low in tannins which are responsible for the bitter taste found in most teas - giving it a sweet flavor profile. As such, it is marketed as an ingredient that can help support energy and performance with potential health-related benefits due to its antioxidant properties. Indeed, ingredients such as these are often consumed by individuals prior to exercise in order to help improve exercise performance, or otherwise to support health-related goals. Whereas several studies have suggested that caffeine and chlorogenic acid consumption may improve performance, mood, and concentration, and some evidence in animals have linked catechin consumption to improved health outcomes, no studies have previous studied whether guayusa extract supplementation helps to support exercise performance in humans. In this study, we will test the whether dietary supplementation with the botanical organic guayusa extract helps support (1) the desire to exercise and exercise performance throughout a 6-week high intensity exercise training program, and thus (2) helps support the physiological adaptations (including body composition, fasting metabolic biomarkers, blood pressure and heart rate, submaximal and maximal exercise performance and fuel metabolism, and changes in the gut microbiome/mycobiome) to a 6-week high intensity exercise training program. Question 1: Does organic guayusa extract supplementation support the desire to train and training load in physically-active women performing a high-intensity exercise training program? Question 2: Does organic guayusa extract supplementation support physiological adaptation to exercise (including body composition, fasting metabolic biomarkers, blood pressure and heart rate, submaximal and maximal exercise performance and fuel metabolism, and changes in the gut microbiome/mycobiome) in physically-active women performing a high-intensity exercise training program?
Researchers at the University of North Carolina at Greensboro conduct a single-arm intervention trial to investigate the efficacy of a music-based group exercise program for community-dwelling older adults. Up to forty participants will be recruited to participate in a music-based light-to-moderate intensity group exercise program for 20 weeks (30 - 40 min/day, up to 6 days/week), which is designed for older adults with or without functional limitations to exercise with chairs for the improvement of aerobic capacity, upper and lower body strength, and balance control at a gradually increasing pace. During the exercise sessions, participants will be trained to move in time with music playlists in synchronous tempos. Primary outcomes are cognitive performance, mobility, and health-related quality of life measured before and after the intervention. Secondary outcomes are adherence to the exercise program as a potential mediator of the treatment.
The 6-minute walk test is a test of physical performance in physiotherapy with lungs and heart patients (Pollentier 2010). However, only 8 and 11% of patients in everyday test situations report a score of 7 or higher on a scale of 0-10 for effort (Jehn 2009). This study is intended to explore, based on grounded theory, why the majority of patients do not assess themselves according to the almost maximum performance.
This study has as main objective to asses different genetic, biochemical and physiological biomarkers affecting performance and health status in ultraendurance runners according to individual's sex.
This study has as main objective to know how the processes of recovery are realized after a race of marathon. For this, the participants of a marathon race are divided into three work groups during the 9 days post-marathon, one with rest in the recovery period, another with continuous race three sessions every 48h and another with three sessions of elliptical every 48h .
The investigators would like to test how well healthy human volunteers power a modified oxygen concentrator. The investigators modified the oxygen concentrator to be powered by a bicycle instead of wall power so that it can be used in low resource countries where the power supply is unreliable.
