Mountjoy 2014 At the heart of the 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.

Ketterly 2019 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.

Clinical Summary of Trexler JSCR 2017. The purpose of this study was to characterize Fat-free Mass Index (FFMI) in collegiate American football players and to determine if FFMI varies with different position, division or age groups. According to earlier research FFMI is a height-adjusted assessment of fat-free mass (FFM), which is derived by dividing FFM (in kilograms) by height (in square meters). Further research suggested a natural upper limit of 25 kg·m2 in resistance trained male athletes. At first FFMI was used as a diagnostic value to identify protein-energy malnutrition in those with low FFM but now it is believed that this value may have valuable applications to a variety of sports. It is believed that FFMI may assist in distinguishing interposition differences comparable to metrics like weight, body mass index, and body fat percentage but may relate more directly to the ability of a player for strength and power.

Clinical Summary of Nowitz JMIRO 2017. The use of dual-energy X-Ray absorptiometry (DXA) has progressively increased in the assessment of irregularities in body composition commonly correlated with disorders such as obesity, sarcopenia, diabetes, anorexia, human immunodeficiency virus, lipodystrophy, malabsorption and neuromuscular disorders. Athletes also use body composition measurements because increases in lean mass lead to increases in strength, power, agility and overall athletic performance. The purpose of this research was to ascertain the short-term in vivo accuracy and least significant change in serial body composition dynamics provided by the Hologic Horizon A densitometer as currently no published, peer-reviewed body composition accuracy data exists on Horizon scanners in medical literature.

Clinical Summary of Shepherd Bone 2017. Dual X-Ray absorptiometry has undergone significant developments to become a device with significant ability to assess body composition. A few examples are the analysis and publication of representative data for the United State, the official usage guidance from the International Society for Clinical Densitometry, and the clinical utility of regional body composition measures are a testament of DXA’s widespread usage and innovation since its creation 30 years ago. Additionally DXA yields the potential to obtain accurate readings over a wide range of body sizes and body type.

Clinical Summary of Milanese J Sports Science 2015. The purpose of this study was to evaluate the in season changes in body composition amongst professional soccer players. It is understood that accurate assessment of body composition is relevant to the player’s physiological status and performance. Furthermore, in season variables such as training, diet and stress of competition may play key roles in changes of an athlete’s body composition and performance.

Kelly TL. 2015 This paper presents a technical discussion of advanced body composition reporting and interpretation. Clinical studies have demonstrated that abnormalities in body composition are a key predictor of health risks, including obesity-related diseases, sarcopenia, and lipodystrophy. The ability to reliably and accurately measure body composition, and present the data in a usable format, enables healthcare providers to identify patients at risk for disease and define and manage treatment programs.

Kelly TL. 2012 Overview: Dual energy x-ray absorptiometry (DXA) body composition measurements are increasingly utilized in the evaluation of clinical obesity,1,2 muscle loss and wasting (sarcopenia),3 and abnormal patterns of fat distribution (lipodystrophy).4 Obesity is widely recognized as a major risk factor for type 2 diabetes, metabolic syndrome, and cardiovascular disease.5 Sarcopenia has been shown to be highly predictive of functional disability in the elderly,6 and lipodystrophy is a major complication of antiretroviral treatments.7 In addition to detecting abnormalities in body composition, DXA is also employed to evaluate the effects of diet and exercise in health clinics8, 9 and physical training in athletes and military recruits.10 Read the Hologic paper Technical Considerations in Advanced Clinical Body Composition Evaluation
