The provision or restriction of select nutrients in an athlete’s diet can elicit a variety of changes in fuel utilization, training adaptation, and performance outcomes. On this episode we discuss the impact of both acute and chronic
carbohydrate restriction on iron metabolism, comparing models of periodized carbohydrate availability and ketogenic low carbohydrate high fat diets.
We also touch base on the link between low energy availability , poor iron status and altered hepcidin activity in endurante athletes. -
Iron deficiency (ID) is a prevailing nutritional concern amongst the athletic population due to the increased iron demands of
this group. Athletes’ ability to replenish taxed iron stores is challenging due to the low bioavailability of dietary sources, and
the interaction between exercise and hepcidin, the primary iron-regulatory hormone. This will be the main focus of this episode. -

On this episode we are talking with Peter Hespel and Chiel Poffé from the University of Leuven / Bakala Academy to provide an update to the topic of exogenous ketones in cycling thanks to their research on this topic. Do ketones improve performance after all? Is there any particular context in which their use is justified? Find out here.

A recent food technology innovation created new CHO drinks and gels with added sodium alginate and pectin in solutions of multiple transportable CHO, with the intention of encapsulating those CHO molecules in the stomach forming a gel which allegedly enables a smooth transportation of the drink through the stomach to the intestine. But are the claims of improved gastric emptying, increased CHO oxidation and reduce GI symptoms supported by science?

On this second episode of this series dedicated exclusively to the female cyclist and endurance female athletes, we are talking again with Kirsty Elliott-Sale and Eimear Dolan about the role of oral contraceptive pills (OCPs) and exercise performance. This episode was based on a recent Meta-Analysis published by the guests themselves on Sports Medicine and they'll tell us what they found. Do OCP users have a lower performance when compared with naturally menstruating women? Is performance superior in OCP taking days vs. OCP withdrawal days? Tune in to find out.

This is a multi-episode series dedicated exclusively to the female cyclist and other endurance female athletes. On this episode we'll go through a recent Meta-Analysis published by Kelly and Kirsty on Sports Medicine and they'll tell us what they found regarding the influence of the different menstrual cycle phases on exercise performance and how can we produce more high-quality research in the future.

On this part 2 on the applicability of low carb, high fat ketogenic diets in endurance athletes, we will resume our talk and put the spotlight on the exercise activities that could benefit from a ketogenic diet approach, as well as some novel areas such as the impact of ketogenic diets in the oral microbiome (nitrate reducing bacteria), it's effects on bone health and the use of exogenous ketones in cycling.

On today's episode with Prof. Louise Burke from the Australian Catholic University, we discuss the current knowledge on the use of low carb, high fat ketogenic diets in endurance athletes, in particulate the research performed by her group with elite racewalkers. Is this diet approach the future of elite endurance sports? Do they have a place in cycling?

Dietary nitrate supplementation produces an ergogenic effect due to the improvement of mitochondrial oxygen efficiency through a reduction in the oxygen cost of exercise that increases vasodilation and blood flow to the skeletal muscle in recreationally active subjects. Today we are talking with Dr. Andrew Jones from the University of Exeter to find out the application of nitrates in cycling.

Exercise-associated physiological disturbances alter gastrointestinal function and integrity. These alterations may increase susceptibility
to dietary triggers, namely gluten and a family of short-chain carbohydrates known as FODMAPs (fermentable oligo-, di-,
monosaccharides and polyols). Today, Dr. Dana Lis talks us through how foods rich in these elements can trigger this symptoms and how to avoid them. -
Over the last decade it has become clearer that taste is not limited to the oral cavity and it can also affect multiple physiological systems resulting in increased exercise performance. On today's episode Russ Best explains how the taste of carbohydrates, caffeine, menthol, capsaicin and bitter compounds can influence exercise performance.

Teun Van Erp, a former Sport Scientist at Team Sunweb developed his PhD on studying the load, intensity and performance of male and female professional riders from Team Sunweb. we’ll go through the training characteristics of pro cyclists, loads, the power zones of cyclists’ when competing, we’ll talk about gross efficiency of pedalling, women vs male road cycling, reliability of some training parameters and some other interesting geeky stuff.

Exhaustive or unaccustomed intense exercise can cause exercise-induced muscle damage (EIMD) and its undesirable consequences may decrease the ability to exercise and to adhere to a training program. Dietary and supplemented polyphenols appear to be a promising way of reducing EIMD. On this episode, we go around the latest evidence on this subject and the applicability it has to athletic populations.

RED-S is the broader, more comprehensive name for what was formerly known as female athlete triad (or simply the triad), which was a condition seen in females participating in sports that emphasize leanness or low body weight. As it was also seen in males, the name was changed to the comprehensive term RED-S which may be more frequent than we think and that can have serious consequences not only for exercise performance of athletes but for their long-term health as well.

In the last years, research in the area of probiotics has progressed considerably and significant advances have been made in the selection and characterization of specific probiotic cultures. As expected, a growing number of dietary supplements containing probiotics are commercially available worldwide, and the number of products being marketed and claiming to improve the health and performance of athletes continues to increase substantially with common oversimplifications and generalization of a complex topic.
In this episode with Dr. Jamie Pugh we’ll present a balanced overview on Probiotic supplementation while recognising how complex the gut microbiota is and the common misinterpretations and limitations of the current research on probiotics use in athletes.

PART 2. The majority of endurance athletes suffer from some kind of gut problem during training and competition. Symptoms like nausea, cramping, bloating, side stitches, and the need to defecate can negatively impact an athlete’s performance. Why are gut problems so common during exercise? And what can athletes do to prevent and manage gut symptoms that occur during training and competition?
