Metabolic Testing
A Plan Built Around You And Your Physiology
Are you a recreational sportsman who wants to get faster, fitter and stronger?
Are you not seeing as much progress as you'd like?
Maybe you're confused with what works and what doesn't?
We can help.
Using VO2Max and metabolic testing, Box Nutrition can provide you with a tailored approach to your training and nutrition, based around you and your physiology.
We understand that everybody is different, which means that your diet and training should not be personal to you.
This can be determined by metabolic testing.
Metabolic testing is what elite athletes use to know what to eat and how to train effectively.
And we can do it for you.
What we test
VO2Max - How big is your engine?
Velocity or power at your aerobic and anaerobic threshold - How good is your engine?
Running economy/cycling efficiency -What's your oxygen cost at your race pace
Fuel utilisation - How effective are you at burning fat?
Energy expenditure - how many kcals do you burn at different intensities/zones
RMR Test - How many kcals do you burn at rest
Testing Data
After testing, athletes will receive a complete breakdown and debrief session running through the testing data.
This includes:
-
Training zones and thresholds
-
Kcal expenditure and speed/watts at each zone
-
Metabolic efficiency point - carb vs fat burn
-
Identification of strengths and weaknesses against normative values
-
RMR report - resting metabolic rate and predicted daily kcal requirements
