Abstract:

Provencher, MT, Chahla, J, Sanchez, G, Cinque, ME, Kennedy, NI, Whalen, J, Price, MD, Moatshe, G, and LaPrade, RF. Body mass index versus body fat percentage in prospective national football league athletes: overestimation of obesity rate in athletes at the national football league scouting combine. J Strength Cond Res 32(4): 1013-1019, 2018-Obesity has been previously noted as a major issue in the National Football League (NFL), where it has been shown that 97% of all players demonstrate a body mass index (BMI) of ≥25.0 with a reported obesity rate of 56% (BMI ≥ 30.0). However, BMI does not take into account body composition by mass, and may overestimate prevalence of obesity. The purposes of this study were (a) to determine the validity of BMI as a measure of body fat percentage and obesity in athletes at the NFL Combine, (b) to define the obesity rate based on body fat percentage compared with BMI, and (c) to determine the relationship between draft status and body composition. It was hypothesized that the rate of obesity, as measured by air displacement plethysmography (ADP), would be less than the rate of obesity as measured using BMI. Athletes who competed at the 2010 through 2016 NFL Combines were included in this study. Air displacement plethysmograph testing at the Combine was performed through BOD POD Body Composition Tracking System with collection of the following metrics: body fat percentage (%), and compared with BMI based on weight and height. In addition, the metrics were evaluated for differences over the 7-year study period to determine temporal changes and to determine draft status based on position relative to BOD POD calculations. A total of 1,958 NFL Combine participants completed ADP body composition testing. Based on BMI (≥30.0), the obesity rate was 53.4% versus an 8.9% obesity rate when using ADP. Drafted players demonstrated a significantly lower body fat percentage than undrafted players (p ≤ 0.05), with the exception of quarterbacks and running backs. All 8 positions of play, with the exception of defensive linemen, demonstrated a decrease in body fat percentage between 2010 and 2017. However, total body mass by position of play remained relatively constant with no significant change noted in any position. In conclusion, the obesity rate in prospective athletes at the NFL Combine was overestimated when calculated based on the BMI. Body fat percentage was more valid for determining an NFL player candidate’s true body composition. Drafted players demonstrated a significantly lower body fat percentage in 6 of 8 positions compared with undrafted players. This is important to recognize for a strength and conditioning professional to use the correct metric when evaluating NFL players who could have been erroneously categorized in the obese population by their BMI. Furthermore, a higher percentage of fat translates to lower chances of becoming drafted.

Success

If you are planning to see Dr Provencher ,do not hesitate ,do it. In 2018 Dr Provencher replaced my LCL. I had no complications and very little pain. I did my physical therapy as prescribed. I was able to ski 30 plus days the winter of 2019-2020. Before seeing dr Provencher I had spent a years time trying to solve my problem locally. I saw a pain specialist, orthopedic urgent care and a orthopedic surgeon. All had access to an mri done locally. It was also read by local radiologist. Pain dr gave injections as did orthopedic urgent care. No relief from pain. Orthopedic surgeon told me about arthritis, meniscus needing cleaning up and general deterioration from age. Told me to take ibuprofen for pain. At that time I reached out to Steadman Clinic. By luck of the draw I was assigned Dr Provencher. I took with me the mri that had been done locally and viewed by 3 local Drs and 1 PA. It took Dr Provencher less than a minute to tell me my problem was my LCL after viewing my mri. He told me my options . I selected surgery as I wanted to continue an active life style. It was a complete success!!

My reverse shoulder replacement

I had my reverse shoulder replacement with Dr.Provencher four months ago. Took an hour, home an hour later. No pain with the meds cocktail, ice machine, and lidocaine pump. My recovery was incredible quick and effortless, no pain and good range of motion. Dr.Provencher is really the best surgeon, and a genuine and kind human being. If you are able to have Dr. Provencher do your shoulder you would be a fool to go anywhere else. The Steadman Clinic is state of the art, extremely efficient, using tranexamic acid intravenously right before surgery to minimize bleeding and many other sophisticated strategies not available in community hospitals. The process and the outcome way exceeded my expectations. If you would like more detail about the experience email me or call on my cell, 3036182303.

My shoulder was ruined in a car accident. I am 82 years old and Dr. Provencher did more than I had ever hoped for. He did a reverse shoulder and at 2 weeks the range of motion exceeded what I had before replacement. He is my hero! Thank you, Dr. Provencher!!
