A case study by Donald Dengel, PhD, Preofessor, Excercise Physiology, University of Michigan. This study reviews how the Horizon® DXA System and body composition analysis creates a symbiotic relationship between collegiate research and athletics

The purpose of this study was to use dual X-ray absorptiometry (DXA) derived total and regional body composition measures to define position specific characteristics in a large cohort of National Collegiate Athletic Association (NCAA) Division 1 football athletes (n=467)1.

Authored by Y.M. Cheung, G. Roff, M. Grossman This clinical summary  discusses why the need to understand the impact of excess fat and fat distribution in individuals at highest cardiometabolic risk has become increasingly more important, especially in the context of targeting intervention and treatment strategies to those at greatest risk.

Authored by Tom Kelly, Hologic, Inc., this paper discusses how DXA continues to represent the gold standard measurement system for body composition in clinical medicine, research, and athletic applications. Continued development and enhancement by Hologic scientists and engineers will keep Hologic DXA body composition applications on the forefront for years to come.

  Authored by John Schousboe, MD, Park Nicollet Clinic & Specialty Center, MN, this whitepaper discusses how VFA imaging at the time of a bone density test is aconvenient and efficient way of identifying patients with one or more prevalent vertebral fractures. This aids in identifying those at high risk of subsequent fracture and for whom fracture prevention therapies are indicated.

A case study focused on how the Fluoroscan InSight FD Mini C-arm system impacted a National Football League team

This study compares the radiation dose delivered and screening times used between standard fluoroscopy and the mini C-arm during foot and ankle surgery. It also provides an estimate of potential cost savings in GBP as of 2009. Please visit PubMed for the full text article.

  International Olympic Committee (IOC) remains the major goal of protecting athletes. The IOC gathered an expert panel to provide these current updates to the 2005 IOC Consensus Statement on the Female Athlete Triad. The triad had previously been described as the combination of disordered eating (DE) and irregular menstrual cycles which potentially lead to decreases in endogenous estrogen and other hormones which may result in low bone mineral density. The current IOC working group presented an extensive, more comprehensive designation reclassified as “Relative Energy Deficiency in Sport” (RED-S). This syndrome denotes impaired physiological ability and goes beyond the triad of Energy Availability (EA), menstrual function and bone health. RED-S is more of a pattern resulting from relative energy deficiency that affects many aspects of bodily function including metabolic rate, menstrual function, bone health, immunity, protein synthesis as well as cardiovascular and psychological wellbeing. Furthermore, it is marked that comparative energy deficiency also afflicts men.

Authored by Jennifer Ketterly, University of North Carolina, in which she shares a case study about an athlete and Visceral Fat Assessment (VAT) made possible by the Horizon DXA™ System. She goes further into how VAT can be associated with cardiac and metabolic disorders. She also highlights how she uses Hologic DXA™ System with her female athlete with nutritional deficits, bone health concerns due to presenting stress fractures, and utilization of DXA for treatment plan and resolution. Read the Hologic white paper for the complete case analysis for the practicing sports dietitian.
