Drop fat, run faster? -A Better Built Triathlete or Just Feel Better Naked?-
This is a follow up to the blog I wrote “It Isn’t Just Strength/Weight Ratio- Last Time I Checked Fat Doesn’t Contract”
I recently invested in an ultrasound cavitation machine to support my clients weight loss journey and performance goals. The technology supports lipid metabolism in those who are already actively and maniacally working to achieve these life objectives. Meaning, they are exercising regularly, following a style of eating that aligns with their desired outcome and are in good health. But can’t seem to spark change in those stubborn areas most of us have.
While the reduction in adipocytes has been demonstrated through medically inspired studies, there isn’t much on the findings of performance advancements in sports who’s weight impacts their athletic effectiveness.
In all honesty, why would there be? Just lose weight the old fashion way- create a caloric deficit and increase work volume or layer up in sweat pants, sweat shirts and hit the sauna. Well, your metabolic and endocrine systems are both mind-bending and complicated systems.
Being the bona fide sports science geek I am, I discussed it with a colleague who I have a tremendous amount of respect for to gain his insight before clipping in and saddling up.
Here is a non-peer reviewed case-analysis with a plausible objective of measuring her running performance while integrating ultrasound cavitation as a means of reducing localized adiposity and using these released energy substrates during running. Again, while there is reason to believe the concept, this is a simple design to express the practical outcomes it could produce.
It is not intended to be interpreted as clinically founded or supported.
We worked to keep her global stress environment as constant as possible to support the efficacy of the study.
The global stress environment for metabolic and structural health
Over the span of 2 weeks, 14 days, I have performed 3-30 minute ultrasound cavitation sessions using 40khz/4mhz on Angel’s abdomen. While there has been an average of 1.5mm site reduction per treatment using skin fold testing, she has seen a marked improvement in her running speed. Now, my wife has one running speed and her coach can attest to this- there are speed-play interval sessions programmed, but struggles to see an increase. She just runs the speed at which she runs and it has been this way for as long as anyone can remember.
To evaluate the effects of high intensity ultrasound on the reduction of abdominal adiposity, the use of energy substrates release from the procedure and the subsequent effect on running performance when body-fat is reduced.
Case-study, 35yr old, age group triathlete performing 4 runs; 3 of equal distance and identical course and the final run being 1.6 longer in distance on a separate course. Three, 30 minute ultrasound treatments, 8/26, 8/30 and 9/4.
8/28/19, First run; 3.89 miles, 11:20/mile pace
9/3/19, Second run; 3.89 miles (same course), 11:10/mile pace
9/5/19, Third run, 3.89 miles (same course), 10:40/mile pace
9/7/19 Fourth run; 6.22 miles, 10:35/mile pace
The data seems to support an increase in running performance when there is a reduction in abdominal adiposity. The evidence is seen here with an 8% increase in average mile time from the first to the final run and a total of 6mm, 1.5mm avg, site reduction in abdominal adipocyte. The data would also suggest it is both a body fat reduction and more readily available energy substrates allowing for a faster and stronger run. Therefore, the results found in the above study suggests that ultrasound cavitation is an effective resource in not only reducing abdominal adiposity, but also improving running performance during a course of multiple sessions.
“It is commonly accepted that it is ideal to be light, powerful and have the capacity to work at near redline efforts for extended periods of time. Runner's Magazine has been quoted in publications as saying a drop in 2lbs, 1%, of body fat is believed to increase your half marathon time by 1 minute and 1:45 for the full 26.2 miles. When you look at the sport's coveted champions- Gwen Jorgensen, Miranda Carfrae, Patrick Lange, Daniella Ryff and/or Jan Frodeno- a common denominator is a low body fat %.” Christopher Ybanez, CSCS, M.S.
