Creatine has been considered an effective ergogenic aid for several decades; it can help athletes engaged in a variety of sports and obtain performance gains. Creatine supplementation increases muscle creatine stores; several factors have been identified that may modify the intramuscular increase and subsequent performance benefits, including basel...

This study investigated the effect of beta-alanine supplementation on short-duration sprints and final 4-km simulated uphill cycling time-trial performance during a comprehensive and novel exercise protocol representative of the demands of road-race cycling, and determined if changes were related to increases in muscle carnosine content. Seventeen...

Supplementation with β-alanine (BA) increases muscle carnosine content, although the amount of BA used for muscle carnosine loading has been suggested to be low. However, methodological issues may have underestimated the amount of BA used. The aim of this study was to determine the estimated amount of BA converted to muscle carnosine, using a retro...

Women’s professional cycling has grown exponentially in popularity in the past years and it has been no different in Brazil. In 2019 the first Brazilian female cycling team achieved UCI ranking status. Nonetheless, there is a paucity of data regarding the seasonal demands that these athletes encounter. This semi-observational study monitored 5 athl...

This study investigated the effect of open-placebo on cycling time-trial (TT) performance. Twenty-eight trained female cyclists completed a 1-km cycling TT following a control session or an open-placebo intervention. The intervention consisted of an individual presentation , provided by a medic, in which the concept of open-placebo was explained to...

Carnosine is an abundant histidine-containing dipeptide in human skeletal muscle and formed by beta-alanine and L-histidine. It performs various physiological roles during exercise and has attracted strong interest in recent years with numerous investigations focused on increasing its intramuscular content to optimize its potential ergogenic benefi...

Background: Administration of open-placebo has shown benefits in several clinical conditions although no study has investigated its effect on exercise performance. Aim: To investigate the effect of open-placebo on exercise performance. Methods: Twenty-eight trained female cyclists completed a 1-km cycling TT following a control session or an open-p...

Purpose: Professional women's road cycling is growing in popularity and increasing in terms of numbers of participants and competitions, and in 2016 the Women's World Tour was established. Female World Tour cyclists can cover between 13 000 and 18 000 km in training and competition each year, including up to 65 competition days (Sanders et al., 201...

Purpose: Professional female cyclists undertake intense training, and the demands of this training must be met by adequate nutritional intake. This is particularly relevant for professional teams who train and compete all year round, as they can cover up to 18 000 km (Sanders et al., 2019). Energy availability (EA) refers to the amount of energy av...

Purpose: Prevalence of dietary supplement use by athletes has been widely investigated, with prevalence in Brazil ranging from 37% to 98% (Nabuco et al., 2016). The American College of Sports Medicine categorises supplements as sports foods, medical supplements, specific performance supplements and others (Thomas et al., 2016). However, not all sup...

Blood alkalosis, as indicated by an increased blood bicarbonate concentration and pH, has been shown to be beneficial for exercise performance. Sodium bicarbonate, sodium citrate and sodium or calcium lactate, can all result in increased circulating bicarbonate and have all independently been shown to improve exercise capacity and performance under...
