Ricerca e progettazione FitYourOutfit: Ing Antonio Talluri

Tony Talluri è noto a livello mondiale ed è considerato un’autorità nel campo dell’impedenza bioelettrica. Nell’arco di circa 40 anni ha sviluppato sistemi innovativi di stimolazione elettrica, bioimpedenziometria, pletismografia, realizzando dispositivi non invasivi per l’analisi qualitativa e quantitativa della Composizione Corporea, classificazione dello stato d’idratazione e nutrizione attraverso dispositivi, nomogrammi, equazioni e concetti interpretativi innovativi, utilizzati a livello internazionale.

L’esperienza ultratrentennale maturata nel ramo “body composition” gli ha permesso, nel 2008, di ideare e promuovere ricerche pubblicate riguardanti un innovativo quanto rivoluzionario sistema da lui ideato e brevettato di misura del corpo, inedito e diverso da qualsiasi altro sistema. Culminato nella realizzazione del metodo FitYourOutfit®, un insieme di tecnologie che consentono di processare e scansionare un’immagine digitale mirato alla stima della massa grassa.

L’impegno nello sviluppo biomedicale di tale sistema innovativo, è stato preceduto ed affiancato da studi di validazione pubblicati e noti in tutto il mondo.

Abstract:

Personal assessments of body phenotype can enhance success in weight management but are limited by the lack of availability of practical methods. We describe a novel smart phone application of digital photography (DP) and determine its validity to estimate fat mass (FM).
This approach utilizes the percent (%) occupancy of an individual lateral whole-body digital image and regions indicative of adipose accumulation associated with increased risk of cardio-metabolic disease. We measured 117 healthy adults (63 females and 54 males aged 19 to 65 years) with DP and dual X-ray absorptiometry (DXA) and report here the development and validation of this application.
Inter-observer variability of the determination of % occupancy was 0.02%. Predicted and reference FM values were significantly related in females (R2 = 0.949, SEE = 2.83) and males (R2 = 0.907, SEE = 2.71).
Differences between predicted and measured FM values were small (0.02 kg, p = 0.96 and 0.07 kg, p = 0.96) for females and males, respectively. No significant bias was found; limits of agreement ranged from 5.6 to 5.4 kg for females and from 5.6 to 5.7 kg for males. These promising results indicate that DP is a practical and valid method for personal body composition assessments.

Abstract

BACKGROUND:
The increasing incidence of obesity and the wider acceptance of laparoscopic surgery, have lead to a 10-fold increase in bariatric operations in the last 10 years. Widely used indices of obesity (weight and body mass index – BMI) cannot adequately distinguish between fat mass (FM), represented by the sum of kilograms (kg) of lipid, and fat-free mass (FFM), inclusive of lean (kg of proteins), bone (kg of minerals), glycogen, and total body water (TBW), which are important parameters for clinical and physiological studies.

METHODS:
Anthropometric variables were measured in 19 Caucasian Italian individuals according to standard methods. Body weight (kg) and height (m) were measured, and BMI was calculated as kg/m(2). Body composition was evaluated, with a mean BMI of 25.95+/-5.04 kg/m(2), by dual X-ray absorptiometry (DXA) and by digital image plethysmographic (DIP) acquisition with a digital camera. The clear-colored body of the subjects was automatically converted into a front and lateral red-shaped figure, and then through algorithms the 2 pictures were transformed into a nominal volume; body weight was then divided by the estimated volume, so that the body density could be obtained. DXA was used as a comparison to assess fat mass and fat-free mass. Radiation exposure was <0.6 mSv.

RESULTS:
Significant positive correlation (R= 0.971, P<0.001) was found between data of body composition obtained by DXA and DIP.
CONCLUSIONS:
Body volume assessed using DIP or DXA did not differ. According to this validation study, DIP represents a new promising tool for clinical applications.

A new simplified method for tracking body volume changes using digital image plethysmography (DiP) (2008)

OBJECTIVE:
Tracking body composition changes during weight-loss interventions is important in both clinical and commercial settings. Accurately tracking body volume (BV) changes can be a useful method to examineweight-loss interventions because BV is not dependent on age, ethnicity, sex,oractivity level. However, measuring BV using air-displacement plethysmography (ADP) or hydrostatic weighing (HW) is expensive, time-consuming, and requires skilled technicians. Therefore, the purpose of the current investigation was to examinethe validity of digital image plethysmography (DiP) for estimating BV before and after a 10-week weight-loss intervention.

METHODS:
Twenty-two men(M)and women(W)(33±6yr; 12M, 10W) volunteered to have their BV estimated by ADP and DiP measurements. Thirteen subjects (8M, 5W) participated in a10-week exercise program (EX) while 9 subjects maintained their current activity level (CON). The following previously validated DiP equation(versus HW, r2=0.99, total error (TE) =1.54L,  SEM=0.85L)was used to track changes using the DiP method: BV=0.0011(side body pixels) +2.08415 (total body pixels to empty pixel space percentage) -69.29694.

RESULTS: Preand Post TE values for both groups were less than 2.55L with high r2 and low SEEvalues (EX r2>0.97, SEE<1.72L; CON r2>0.98, SEE<1.94L). DiP accurately estimated BV changes (EX TE=1.06 L, SEE=1.00 L; CON TE=0.83 L, SEE=0.47 L) which were not significantly different (constant error, EX=-0.53, CON=0.33p>0.05) compared to ADP.
CONCLUSION:
The new DiP-based BV equation produced low SEE and TE values andhigh r2 values in both the EX and CON groups and accurately tracked BV changes. Therefore, DiP can be considered a valid method for estimatingand tracking BV in men and women.
