PURPOSE: To determine which anthropometric equation used to estimate body composition in athletes with chronic spinal cord injury (SCI) has better concordance with Dual X-ray absorptiometry.
METHODS: Seventeen male athletes with chronic SCI AIS A or B, participated from this study. Body composition was estimated using two anthropometric equations (Kerr Ross and Durnin Womersley). The evaluation was performed with the athlete in the supine/prone position and seating in their wheel chair. The same day a DEXA scan was performed. Shapiro Wilk test was used and results were analyzed with student T test, Pearson correlation test and Bland & Altman method.
RESULTS: The athletes were 30,9 year old (SD: 7,1), they trained 14,5 (SD 7,7) hours a week and averaged 5,4 years of experience in sports. They had 29,5% Fat Mass (FM) (SD: 7,3) and 48,6 (SD: 5,5) kilograms of Free Fat Mass (FFM) measured with DEXA scan. There was no difference between FM and FFM results determined by DEXA scan and those estimated by Kerr Ross Method (p<0,001). There was a significant difference between DEXA scan results and estimations by Durnin Womersley equation (p>0,05). No difference was found when comparing anthropometric results with the athlete in the supine/prone position and seating in their wheel chair. The correlation between FM and FFM measured with DEXA scan and the estimated By anthropometric equation where superior for Kerr Ross method (r=0,75 and r = 0,86 respectively). The average difference between DEXA scan results and Kerr Ross method estimation for FM and FFM was: 0,84% (SD= 5.04) and -0,39 kilograms (SD= 3,49) respectively.
CONCLUSIONS: When using anthropometric evaluation to estimate body composition in athletes with SCI, Kerr Ross method is superior to Durnin Womersley equation. But this method does not have acceptable agreement with DEXA scan for clinical purposes. Anthropometric evaluations are easily performable in the field and affordable, but more research is needed to determine the best method to estimate body composition in athletes with SCI.
