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 ... -
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 ... -
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 ... -
An exploratory investigation of endotoxin levels in novice long distance triathletes, and the effects of a multi-strain probioyic/prebiotic, antioxidant intervention
Roberts, Michael; Roberts, Justin; Suckling, Craig; Peedle, Georgia; Dawkins, Tony G. (2016-11-17)Gastrointestinal (GI) ischemia during exercise is associated with luminal permeability and increased systemic lipopolysaccharides (LPS). This study aimed to assess the impact of a multistrain pro/prebiotic/antioxidant ... -
Indexing Dialysis Dose for Gender, Body size and Physical Activity: Impact on Survival
Sridharan, Sivakumar; Wellsted, David; Vilar, Enric; Davenport, Andrew; Ashman, Neil; K Almond, Michael; Banerjee, Anindya; Roberts, Justin; Farrington, Kenneth (2018-07-25)Background Current practice basing dialysis dose on urea distribution volume (V), has been questioned. We explored the impact on survival of scaling dialysis dose (Kt) to parameters reflective of metabolic activity. ... -
The ingestion of protein with a maltodextrin and fructose beverage on substrate utilisation and exercise performance
Tarpey, Michael; Roberts, Justin; Kass, Lindsy; Tarpey, Richard; Roberts, Michael (2013-12)The study investigated the ingestion of maltodextrin, fructose and protein on exogenous carbohydrate oxidation (CHOEXO) and exercise performance. Seven trained cyclists/triathletes (VO2max: 59.20 ± 9.00 ml •kg-1•min-1) ... -
An investigative study into the influence of a commercially available carbohydrate-protein-electrolyte beverage on short term repeated exercise performance
Roberts, Justin; Tarpey, Michael D.; Kass, Lindsy; Roberts, Michael G. (2012)Background: The purpose of this study was to undertake an independent investigation into the effects of ingesting a carbohydrate-protein-electrolyte (CPE) beverage on repeated submaximal and time-trial cycling performance. ... -
Scaling Hemodialysis Target Dose to Reflect Body Surface Area, Metabolic Activity, and Protein Catabolic Rate : A Prospective, Cross-sectional Study
Sridharan, Sivakumar; Vilar, Enric; Davenport, Andrew; Ashman, Neil; Almond, Michael; Banerjee, Anindya; Roberts, Justin; Farrington, Kenneth (2017-03-01)BACKGROUND: Women and small men treated by hemodialysis (HD) have reduced survival. This may be due to use of total-body water (V) as the normalizing factor for dialysis dosing. In this study, we explored the equivalent ... -
A self-report comorbidity questionnaire for haemodialysis patients
Sridharan, Sivakumar; Berdeprado, Jocelyn; Vilar, Enric; Roberts, Justin; Farrington, Ken (2014-08-18)Background: Patients with end-stage renal disease (ESRD) have multiple comorbid conditions. Obtaining comorbidity data from medical records is cumbersome. A self-report comorbidity questionnaire is a useful alternative. ... -
A valid and reliable nutrition knowledge questionnaire for track and field athletes
Furber, Matt; Roberts, Justin; Roberts, Michael (2017-04-12)Background Establishing an understanding of an athlete’s nutrition knowledge can inform the coach/practitioner and support the development of the athlete. Thus the purpose of the study was to develop a psychometrically ...
