Ergogenic aids used by ultra-marathon runners
… Athletes of all levels and abilities utilise ergogenic aids to enhance sporting performance. However, the extent of ergogenic aid use within the ultra-marathon running community in unknown and there is little available literature documenting characteristics of use among ultra-marathon runners. …

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 …

Investigating the Ergogenic Potential of Ischemic Preconditioning and Resisted Running on Sprint Performance
Two pre-competition protocols were constructed based on physiological principles related to muscle contractile properties and ischemia-induced metabolic and neural changes. Sprint times over 0-20 m were used to assess the effectiveness of these protocols, which were designed to potentially provide …

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 …

Synthesis and characterization of amino acid complexes of physiological metal ions to be used as ergogenic aids
… is necessary during extended physical exercise. Ergogenic aids are very broad range of physical, pharmacological or other aids including electrolyte and hydration supplementation. The current approaches to supplemental hydration therapy uses isosmotic, electrolyte and sugar solutions which help …

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 ergogenic effect of transcranial direct current stimulation on cycling time to exhaustion task performance in physically active people.
… objective of this thesis was to investigate the ergogenic effect of transcranial direct current stimulation on endurance exercise performance in physically active people. In the first study, we performed a systematic review and meta-analysis to quantify the effect of a-tDCS on endurance (TTE and …

The impact of acute and chronic administration of short-acting β2-agonists on urinary pharmacokinetics and athletic performance
… limited data currently exists examining the ergogenic and pharmacokinetic impact of chronic short-acting β2-agonist administration. Furthermore, the ergogenic impact of acute and chronic administration of short-acting β2-agonists in asthmatic individuals is unknown. Whilst the short-acting …

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.

The Role of Dopamine on Central Neuromuscular Activation during Passive Hyperthermia
… isolated. One potential explanation for this ergogenic benefit is that MPH intake was enhancing neuromuscular activation. Thus, this research project examined the influence of MPH on neuromuscular activation during hyperthermia. Participants ingested either placebo (PLA; 20mg) or MPH (Ritalin; …

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 …
-
The effects of prior oral creatine supplementation on performance and metabolism after 7 days of sprint cycle training
… been demonstrated as partly responsible for this ergogenic effect. Also, there is evidence that high-intensity sprint training results in a decrease in muscle total adenine nucleotide (TAN) and/or ATP stores. This placebo controlled double-blind study examined whether an oral creatine …

The Effects Of Caffeine Supplementation When Manipulating The Time Of Ingestion Prior To Simulated Rugby Union Activity
… ingestion prior to activity to elicit an ergogenic effect remains unclear. </p> <p>Methods: Athletes from a women and men's university club rugby squad were recruited for this study (n=22). Athletes were measured for height, weight, body composition, and resting blood pressure. Body …

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 …

The Effects of Caffeine on Performance of Trained Cycling Athletes
… caffeine has an impact, further determining what ergogenic effects caffeine has, the process of caffeine methods, and comparing methods to other options lead to various studies on purpose of this study. Fifteen articles were found to be delimited enough to gain access to a vast amount of knowledge …

The acute effects of transdermal testosterone precursor administration on serum steroid hormone levels in females
… have banned the use of anabolic steroids as ergogenic aids. Recently, a transdermal testosterone precursor dietary supplement (AndrosteDERMRTM) has become available; athletes can apply the cream to their skin with the belief that it will increase serum testosterone levels, muscle mass, and …

The role of lactate supplementation and metabolism in invasion sport performance
… may be recommended prior to rugby matches as an ergogenic aid to sustain sprint performance although any benefit is likely to be marginal.<br/><br/>Study 2 investigated the effect of sprint interval training on soccer specific performance indices and lactate kinetics. In youth soccer, 23% of the …
