Body composition is one of the factors that contribute to optimal exercise performance. Body composition can affect and athlete´strength and appearance. Optimal body fat levels depend upon the sex, age, and may be sport‐specific. Athletes their calorie needs may approach 50‐80 kcal/kg/day.ObjectiveTo compare %Fat Free Mass(FFM) and Fat Mass(FM) between three body composition devices in young athletes evaluated energy intake. Methodology:Air Displacement Plethysmograph(BODPOD) was used by body density and body fat percentage calculated using the Siri equation. Near‐infrared spectroscopy, Bioelectrical impedance analysis(BIA) and Air Displacement plesthysmograph were used to determinate %FFM and %FM. According to the muscle and fat areas categorized subjects in low standard, Normal, and on the rule. The 24‐henergy‐expenditure(24‐h EE) was taken to reported energy‐intake(EI) Results:This study assessed fifteen young athletes, 40% women and 60% men, average age 22 years. Moderately Lean, Lean and Risky (high body fat)were FM, 86%, 7% and 7%, respectively. There was no difference between Air Displacement Plethysmograph and Near‐infrared spectroscopy(p=0.22), and was significant difference between Air Displacement Plethysmograph and BIA(p=0.1). EI(47%)appeared adequate and matched their estimated Total Energy Expenditure(TEE) but 53% were low EI and did not match their TEE.Conclusion:Despite the inherent problems of measurement, this techniques remains a method of choice because it is convenient, reliable and requires minimal technical expertise. Thus, part of the %FM and %FFM on a seemingly low EI appears and may have micronutrient deficiency, further analysis should be taken.
