Our Perspective on Human Performance

Live Demo – Wed 21st Jan @7pm VeloSport, Putney

  This live demonstration of a full lactate threshold profile will provide valuable insight into current endurance sports performance assessment and best practices.  VeloSport’s own Steve James will be the test subject on the night…so come along and witness his suffering! The lactate threshold power/ heart rate is an important parameter of cycling performance, and is now commonly used […]

Lactate is unique!

Lactate is unique!

I have previously described the three primary independent factors which dictate endurance cycling performance which are known to applied exercise physiologists….   1. Gross cycling efficiency – the ability to use oxygen and convert fuel (carbs/fats/ protein etc) to energy in the muscles and is dictated by individual expression of specific metabolic enzymes which control […]

Hi’s and Lo’s of cycling

Hi’s and Lo’s of cycling

As the last of the Northern classics are finished, and the Giro is looming, now is the time that many of you who are in store for some Continental cycling, or a late Spring training camp further afield will be anticipating some long awaited back-to-back days of ascending and descending some legendary pro-tour climbs! As many of my […]

Although now known as the most informative and accurately trackable performance parameter in cycling (and running), one of the most useful and direct applications for Maximal Lactate Steady State values are in Time-Trial, Duathlon and Triathlon, for a multitude of physiological reasons.  Recently, I had the pleasure of profiling the lactate kinetics of three up-and-coming […]

Reasons to profile your lactate kinetics

Reasons to profile your lactate kinetics

One day I believe we will have real-time lactate and glucose measurements, with feed back biometrics from biosensors and our power-meters, displayed to us through ‘Reality Glasses’ or something ridiculous like that. But until that day, the best way of understanding these biochemical processes during our simulated performance is through a good physiologist or sports scientist who appreciates […]

Supercompensation- is not just a big word.

Supercompensation- is not just a big word.

If I had to choose what I felt was the most important aspect behind any of the principles of applied exercise physiology, then without doubt I would pick Supercompensation above the rest. Supercompensation explains the mechanism behind how we, as organisms, adapt and respond to any physical stimulus, and is therefore fundamental to performance progression. […]

Investigating Super Starch (Generation UCAN)

Investigating Super Starch (Generation UCAN)

I believe in serendipity. The process of stumbling across a significant finding purely by chance, totally unaware of its potential application. Many great discoveries have been made this way (Viagra, Penicillin and even the microwave oven), as opposed to systematically being teased out, fabricated and ultimately commercialised, with many not standing the true test of […]

Whole Body Metabolism & Micronutrition 101

Whole Body Metabolism & Micronutrition 101

Diet and nutrition is often seen as a contentious subject. The topic is filled with polarised opinions and confusion, often fabricated by over zealous ‘clinical’ nutritionists relying on anecdotal observation or limited clinical evidence at best. The pseudoscientific journalists writing in magazines or online media sponsored by industry giants, trying to sell more advertising space […]
