Lones Wigger, double Olympic winner for shooting, shares the required mindset for success. I put it to the test at a competitive rifle range.
July 14th 2016 – I have completed my first body composition analysis using a BodPod.
My statistics are as follows:
Age & Height
- Age – 25
- Height – 72ins (182 cms) or 6ft
Weight, Body Fat & Lean Tissue
- Total Weight – 70.8kg
- Lean Weight – 66.1kg
- Fat Weight – 4.8kg
- Body Fat Percent – 6.7%
- Lean Tissue Percent – 93.3%
- Density – 1.086 kg/l
- (Methodology: Brozeck 1963)
Energy Expenditure & Basal Metabolic Rate
- Estimated Energy Expenditure – 2897.1 Kcals/day
- Estimated Basal Metabolic Rate – 1793.4 Kcals/day
Pulse & Blood Pressure
- Pulse (resting) – 55 bpm
- Blood Pressure – 114.5/71
Body Measurements (inches)
- Chest – 41
- Mid-Waist (belly-button) – 32
- Hip-Waist (trousers) – 33
- Bicep (semi-flexed) – 12.5
- Thigh (9ins up from knee) – 20.75
- Calve (12ins up from ankle) – 14
Notes on the composition analysis
The BodPod analysis was done four times. 2×2 using different equations.
The first equation model used was Siri 1961:
% Body Fat = (495 / Body Density) – 450
The second equation model used was Brozeck 1963:
% Body Fat = (457 / Body Density) – 414.2
Daphne, the technician who supervised my visit at the British College of Osteopathic Medicine suggested that as my body fat was below 10%, the accuracy of the Brozeck 1963 model was better suited. While I have not found any papers referencing this, I have trusted her word and used Brozeck 1963 results above.
- Blood pressure and heart rate was taken twice and I have noted the mean average.
- The formula for estimating total daily energy expenditure assumed I do an ‘active’ level of physical activity based on my explanation that I do 2-4 hours of martial arts per week, and walk an average of 7.9km per day (as measured by Apple Health).
Daphne, the technician, explained my body fat percentage was below the recommended 10% for someone of my age, sex and height. I believe my phenotype has always been that which expresses a low body fat percentage for I consume a normal diet (one which I am now recording in a food diary) and do not avoid any foodstuffs or alcohol.
Readers will know I enjoy self-experimentation, but this is the first time I’ve gone into the physical realm. Lawrence Neal, #1 High-Intensity Training podcaster, has challenged me to a 30-day experiment with HIT workouts, created by Doug McGuff in Body by Science. The BodPod is to analyse the before and after results.
