A 7-day high protein hypocaloric diet promotes cellular metabolic adaptations and attenuates lean mass loss in healthy males
Furber, Matt; Anton-Solanas, Ana; Koppe, Emma; Ashby, Charlotte; Roberts, Michael; Roberts, Justin (2017-08-31)Mitochondrial quantity and density are associated with increased oxidative metabolism. It has been demonstrated that a hypocaloric high fat/low carbohydrate (HF/LC) diet can up-regulate transcriptional markers of mitochondrial ... -
Assessing a commercially available sports drink on exogenous carbohydrate oxidation, fluid delivery and sustained exercise performance.
Justin, Roberts,; Tarpey, Mike; Kass, Lindsy; Tarpey, Richard; Roberts, Michael (2014-03-04)Background: Whilst exogenous carbohydrate oxidation (CHOEXO) is influenced by mono- and disaccharide combinations, debate exists whether such beverages enhance fluid delivery and exercise performance. Therefore, this study ... -
Behavioural effects of electrical stimulation of the hypothalamus of the goldfish (Carassius auratus)
Roberts, Michael; Savage, George (1975)Food-satiated goldfish were stimulated in tanks containing food on the surface of the water and on the bottom of the tank. Various components of the feeding response were seen, and complete feeding was observed, which was ... -
A case study evaluation of competitors undertaking an Antarctic ultra-endurance event : nutrition, hydration and body composition variables
Paulin, Scott; Roberts, Justin; Roberts, Michael; Davis, Ian (2015-03-12)The nutritional demands of ultra-endurance racing are well documented. However, the relationship between nutritional consumption and performance measures are less obvious for athletes competing in Polar conditions. Therefore, ... -
Comparing Acute, High Dietary Protein and Carbohydrate Intake on Transcriptional Biomarkers, Fuel Utilisation and Exercise Performance in Trained Male Runners
Furber, Matthew; Pyle, Simone; Roberts, Michael; Roberts, Justin (2021-12-08)Manipulating dietary macronutrient intake may modulate adaptive responses to exercise, and improve endurance performance. However, there is controversy as to the impact of short-term dietary modification on athletic ... -
Dissecting the molecular pathways underpinning lifespan extension following exposure to Montmorency Tart Cherries.
Vrinds, Inge; van den Elzen, Amber; Desai, Terun; Roberts, Michael; Lokman, Christien; Bottoms, Lindsay; Hughes, Samantha (2017-06) -
The effect of a decaffeinated green tea extract formula on fat oxidation, body composition and exercise performance
Roberts, Justin; Roberts, Michael; Thomas, Clare; Weeks, Jack; Tarpey, Michael (2015-01-21)The cardio-metabolic and antioxidant health benefits of caffeinated green tea (GT) relate to its catechin polyphenol content. Less is known about decaffeinated extracts, particularly in combination with exercise. The aim ... -
The effects of bombesin on feeding in fish
Roberts, Michael; Beach, Mark A.; McVean, A.; Thorndyke, Michael C. (1988-01) -
THE EFFECTS OF MONTMORENCY TART CHERRY JUICE SUPPLEMENTATION AND FATMAX EXERCISE ON CARDIO-METABOLIC MARKERS IN HEALTHY HUMANS
Desai, Terun; Bottoms, Lindsay; Roberts, Michael (2017-05-02) -
The effects of Montmorency tart cherry juice supplementation and FATMAX exercise on fat oxidation rates and cardio-metabolic markers in healthy humans
Desai, Terun; Bottoms, Lindsay; Roberts, Michael (2018-12-01)Montmorency tart cherries (Prunus cerasus L.) are rich in anthocyanins, compounds capable of augmenting fat oxidation and regulating metabolic dysfunction. The present study examined whether Montmorency tart cherry juice ... -
Effects of Montmorency Tart Cherry Supplementation on Cardio-Metabolic Markers in Metabolic Syndrome Participants: a pilot study
Desai, Terun; Roberts, Michael; Bottoms, Lindsay (2019-04-16)This study compared acute supplementation of Montmorency tart cherries in capsule (MTCC) and juice (MTCJ) forms in MetS humans, as potential prophylactic interventions against cardio-metabolic diseases. In an acute, ... -
Effects of Short-Term Continuous Montmorency Tart Cherry Juice Supplementation in Participants with Metabolic Syndrome
Desai, Terun; Roberts, Michael; Bottoms, Lindsay (2020-08-12)Purpose: Metabolic Syndrome (MetS) augments the incidence of cardiovascular disease by two-fold and type II diabetes mellitus by five-fold. Montmorency tart cherries are rich in phytochemicals shown to improve biomarkers ... -
Efffects of hypothalamic lesions on the food intake of the goldfish (Carassius auratus)
Roberts, Michael; Savage, George (1978)Goldfish were trained to perform an operant response in order to obtain food, thereby allowing the food intake to be accurately determined. The normal daily food intake was established for each fish before it was given a ... -
Electrocardiographic changes following six-months of long-distance triathlon training in previously recreationally active individuals
Dawkins, Tony G.; Shave, Rob; Baggish, Aaron; Drane, Aimee; Parisi, Erika; Roberts, Michael; Justin, Roberts, (2019-07-31)Background: Clinical electrocardiographic (ECG) guidelines for athlete’s heart are based upon cross-sectional data. We aimed to longitudinally evaluate the influence of endurance training on the ECG and compare the prevalence ... -
