(1) INTRODUCTION

The use of supplements in both elite and recreational level sport has grown tremendously in recent years (Knapik et al. 2016). Opinions are clearly split as to whether supplements are a necessary component of the athlete’s diet, and the reasons for using supplements are broad. Whilst there is a time and place for supplements, we believe in a simplistic yet discerning approach to advocating them. Moreover, the choice of which supplement brand to use has become more difficult than ever due to the demand of aesthetic focussed supplements containing banned substances or manufactured in third party labs where contaminants may spoil a ‘clean’ supplement. This position stand will address topical issues surrounding supplement use in sport and provide a clear outline of the practical considerations for utilising supplements in a safe and effective way.

In the land of cycling nutrition, carbohydrate is king. It provides the quick hit of energy required to get riders through the interval sessions that we’re told we need to build power and speed. The result is that we have become loyal subjects to the mighty carbs, and our bodies have become reliant on them for fuelling our rides. But it could be that we are serving the wrong master. Broadly speaking, the average cyclist carries enough glycogen (carbohydrate stored in the muscles) to fuel about 90 minutes of activity – barely enough to get most riders to their first cafe stop. Further, carbohydrate oxidation (ie burning energy) has a strong correlation with lactate production, which limits performance. So to improve, we need to become more metabolically efficient, which is why Cyclist has come to Guru Performance in Mayfair, London, to see Laurent Bannock, a scientist at the forefront of metabolic efficiency training.

All hail fat

‘Metabolic efficiency is the ability of an individual to utilise their most significant on-board fuel supply – body fat – for as much of the exercise duration as possible,’ Bannock says. ‘Fat is the most sustainable energy source for an athlete, and delays the accumulation of lactic acid by sparing glycogen stores. However the situation is complicated by the fact that an athlete must also be metabolically flexible – able to switch rapidly and proficiently between the body’s fuel sources to match the fluctuating intensities of competitive events. Don’t worry, we’ll revisit this later,’ he tells me with a grin, as if sensing my growing incomprehension.

Nutrition expert Laurent Bannock dishes on your best nutrition solution

Bicycling Magazine – Aug 5, 2015 (read full article)

Whether you’re looking to improve performance or shed pounds, you’ve likely heard someone mention a high-fat/low-carb or high-carb/low-fat diet. Both diets get media hype (one more than the other, depending on the week), which caused us to wonder: Which is better for cyclists? It turns out that—no surprise—the answer isn’t as clear as we would hope.

Laurent Bannock, founder and director of Guru Performance, is an expert nutritionist responsible for the training and nutrition of many elite British athletes, and quite a few celebrities as well. The fact that the fat/carb debate has become a hot-button issue, Bannock says, is overblown.

For starters, there is no one definition of what it means to be low- or high-fat, or low- or high-carb. Some experts define a fat-adapted diet as one with between 20 and 60 grams of carbohydrates per day, while other low-carb diet still allow for 100 grams per day. And a low-fat, high-carbohydrate diet’s daily carb grams largely depend on your activity level.

“It’s a ludicrous conversation, which camp we’re in, high-fat or carb,” Bannock says. “We should be in both. It’s the same with, ‘Which is more important, the front or rear wheel of your bicycle?’ They’re both important.” To settle the dispute once and for all, he shared his best insights from years of research and real-world experience.
