The Ergogenic Effects of Oxygen Supplementation on Cycling Performance
… oxygen supplementation has been proposed as an ergogenic aid in a range of sports and endorsed by various governing bodies (including the NFL and the NBA). Originally the use of oxygen supplementation in research was related time trial and time to exhaustion performances, i.e. predominately …

Ergogenic Effects of Intake of Salbutamol, Caffeine and Theobromine on Non-Asthmatic Subjects
… there are no available data examining the ergogenic effect of inhaling a single bolus of the upper daily limit of 1600 µg or the impact on urine concentration of the short-acting β2-agonist and its relationship with the WADA code. Meanwhile, caffeine and theobromine have been regarded as …

Vitamin and mineral supplementation in athletes, with special reference to the ergogenic effects and possible toxic side-effects
The use of vitamin and mineral supplements as ergogenic aids is widespread amongst both athletes and the general population. Although there appear to be at least some theoretical reasons to suggest that supplementation may enhance athletic performance, there is limited scientific justification for …

The effect of carbohydrate-loading and carbohydrate ingestion on fuel substrate kinetics during prolonged cycling
… the precise mechanism(s) underlying the proposed ergogenic effects of these procedures remain to be established. The studies in this thesis were therefore designed to examine the effects of carbohydrate-loading and carbohydrate ingestion on fuel substrate kinetics.

Transcranial Direct Current Stimulation of the Dorsolateral Prefrontal Cortex Does Not Improve Handgrip Time-to-Failure or Alter Central or Peripheral Hemodynamics
… (all <em>p </em>> 0.05). A linear mixed-effects model revealed no significant main effect of condition on recovery MVC (<em>p </em>> 0.05). This study provides evidence tDCS does not improve HGTTF in older adults, adding contrastingevidence regarding the effects of an acute session of …

The impact of multiple acute turkesterone doses on indirect hypertrophy and metabolic measures : a preliminary investigation.
… properties with no reported adverse side effects compared to traditional anabolic androgenic steroids. However, this ostensible enhancement to increase muscle protein synthesis (MPS) remains hitherto undescribed. To investigate whether turkesterone enhances insulin like growth factor 1 …

Effects of buffering agents on high-intensity exercise performance and capacity
… acidosis. Despite this, studies on the ergogenic effects of β-alanine are still in their infancy, and research on sodium bicarbonate remains equivocal. The aim of this thesis was to investigate the separate and combined effects of β-alanine and sodium bicarbonate on high-intensity …

The effects of caffeine sensitivity on metabolic substrate use and performance
… in these parameters. These data suggest that the ergogenic effects of caffeine in some individuals are not due to an alteration in substrate utilization, but may be related to an alteration in neural perception of effort.

The effects of creatine supplementation on performance and metabolism during brief, intermittent, high-intensity exercise
This study investigated the ergogenic and metabolic effects of creatine supplementation during two series of 10 x 6 s of "all out" cycling sprints, interrupted by either 30 s rest intervals (RI). Both sprint series were performed before and after five days of oral supplementation with either …

Anabolic-androgenic steroids : a series of meta-analyses
… summarize the psychological, physiological, and ergogenic effects of anabolic-androgenic steroids (AAS)s in healthy humans. Using the format of a meta-analysis, data from 127 studies and 35 outcomes was converted into 894 effect sizes and summarized across studies. In order to account for any …

The effects of carbohydrate and protein hydrolysate co-ingestion upon exercise metabolism and cycling performance
The ergogenic effects of acute carbohydrate (CHO) supplementation during prolonged exercise are well established. Recently, a number of studies have examined the potential for the inclusion of protein to further augment these efficacious effects. However, observations at present remain equivocal. …

The Effect of Betaine Supplementation on Performance and Muscle Mechanisms
… power performance. To further investigate the ergogenic effects of betaine supplementation a balanced, randomized, double-blind, repeated measures crossover study was designed to examine select hormonal and muscle signaling responses during supplementation.</p> <p><strong>Methods: …

The Effects of Carbohydrate and Quercetin on Team Sport Athletic Performance and Exercise-Induced Inflammation and Oxidative Stress
… have both shown evidence of producing an ergogenic effect and attenuating inflammation and oxidative stress with prolonged endurance exercise. Less is known about how these interventions may influence intermittent, high-intensity exercise characteristic of soccer. In particular, this …

An investigation into the novel effects of melatonin treatment on differentiated C2C12 myotubes in the absence and presence of pathology
… pro-survival pathways. MEL intake may have ergogenic effects on healthy muscles in the absence of pathology; for example, consumption before sporting events or physical exercise may help reduce fatigue. For instance, consuming MEL before participating in sports or physical exercise may help …
