Quantity and timing of protein ingestion are major factors regulating myofibrillar synthesis (MPS). However, the effect specific patterns on MPS throughout a 12 h period is unknown. We determined how different distributions feeding during recovery after resistance exercise affects anabolic responses in skeletal muscle. Twenty-four healthy trained males were assigned to three groups (n = 8/group) undertook bout followed by 80 g whey one following protocols: 8 × 10 every 1.5 (PULSE); 4 20 3...
Identification, evaluation and management of disordered eating (DE) is complex. DE exists along the spectrum from optimised nutrition through to clinical disorders (EDs). Individual athletes can move back forth behaviour at any point in time over their career within different stages a training cycle. Athletes are more likely present with than ED. Overall, there higher prevalence EDs compared non-athletes. Additionally, participating aesthetic, gravitational weight-class sports risk those...
We determined the effects of varying daily carbohydrate intake by providing or withholding during training on endurance performance, whole body rates substrate oxidation, and selected mitochondrial enzymes. Sixteen endurance-trained cyclists triathletes were pair matched randomly allocated to either a high-carbohydrate group (High group; n = 8) an energy-matched low-carbohydrate (Low for 28 days. Immediately before study commencement final 5 days, subjects undertook 5-day test block in which...
We determined the effects of "periodized nutrition" on skeletal muscle and whole body responses to a bout prolonged exercise following morning. Seven cyclists completed two trials receiving isoenergetic diets differing in timing ingestion: they consumed either 8 g/kg mass (BM) carbohydrate (CHO) before undertaking an evening session high-intensity training (HIT) slept without eating (FASTED), or 4 BM CHO HIT, then sleeping (FED). The next morning subjects 2 h cycling (120SS) while overnight...
To develop and investigate the efficacy of a new precooling strategy combining external internal techniques on performance cycling time trial (TT) in hot humid environment.Eleven well-trained male cyclists undertook three trials laboratory-based TT simulating course characteristics Beijing Olympic Games event controlled environment (32°C-35°C at 50%-60% relative humidity). The trials, separated by 3-7 d, were undertaken randomized crossover design consisted following: 1) CON-no treatment...
Standardizing a dual x-ray absorptiometry (DXA) protocol is thought to provide reliable measurement of body composition. Purpose We investigated the effects manipulating muscle glycogen and creatine content independently additively on DXA estimates lean mass. Method Eighteen well-trained male cyclists undertook parallel group application loading (n = 9) (20 g·d−1 for 5 d loading; 3 maintenance) or placebo with crossover (12 v 6 g·kg−1 BM per day 48 h) as part larger study involving...
Creatine (Cr) and carbohydrate loadings are dietary strategies used to enhance exercise capacity. This study examined the metabolic performance effects of a combined CR CHO loading regiment on time trial (TT) cycling bouts.Eighteen well-trained (~65 mL·kg·min V˙O2peak) men completed three trials (PT) that comprised 120-km TT interspersed with alternating 1- 4-km sprints (six each) performed every 10 km followed by an inclined ride fatigue (~90% V˙O2peak). Subjects were pair matched into...
Background Hypohydration and hyperthermia are factors that may contribute to fatigue impairment of endurance performance. The purpose this study was investigate the effectiveness combining glycerol hyperhydration an established precooling technique on cycling time trial performance in hot environmental conditions.Methods Twelve well-trained male cyclists performed three 46.4-km laboratory-based trials included two climbs, under humid conditions (33.3 ± 1.1°C; 50 6% r.h.). Subjects were...
Abstract Background Despite the high prevalence of disordered eating and disorders amongst elite athletes, it remains unclear whether risk factors psychological processes align with those in general population or if there are unique sport-factors associated heightened risk. This cross-sectional study investigated sport-specific (including pressures processes) explained additional variance athletes’ symptoms, controlling for established population-general factors. Current athletes ( N = 178,...
The direct quantification of muscle glycogen storage or utilization during exercise involves an invasive biopsy protocol, while indirect measurements via magnetic imaging require expensive and inaccessible equipment. Recently, ultrasound technology has been promoted as a practical, non-invasive technique for determining based on changes in the grey scale image associated with glycogen-binding water. If valid, this would have widespread application applied sports nutrition. PURPOSE: To...
Compulsive exercise is linked with poorer treatment outcomes in people eating disorder (EDs). High-performance athletes represent a growing and complex subcomponent of the broader ED population, emergent evidence indicates that different conceptualisations compulsive are needed this population. Existing randomised controlled trials populations have demonstrated small effects on compared control groups; however, were sparsely sampled across these studies. Thus, extent to which current...
ABSTRACT Background Elite athletes experience unique pressures and cognitions associated with disordered eating, which may not be appropriately captured by existing tools. The Athletic Disordered Eating (ADE) scale is a recently developed first measure of eating specifically validated in current former athletes. This study aimed to provide further validation for the ADE an independent sample elite Method Participants were 237 ( M Age = 26.1, SD 8.6; 75.9% female; 73.0% athletes)...
Muscle protein synthesis (MPS) is synergistically enhanced by resistance exercise and feeding with mRNA translation initiation being a critical regulatory step. Previous studies indicate 20 g of immediately after maximally stimulates MPS during the early recovery period. However, no have examined effect manipulating quantity timing ingestion on anabolic signaling over whole day. PURPOSE:To determine time-course prolonged from exercise. METHODS: 24 trained men were randomly assigned to one...
