Assessment of body composition variables: Comparison between young trained athletes and healthy subjects
Abstract
The aim of this study was to describe and compare the current profile of selected young athletes subjects and healthy male subjects base on body composition variables. The research group consisted of two 16 - years old male group from Czech Republic.
The group 1 (Trained athletes): n = 57, age = 16.2 +- 0.6 years, body height = 177.21 +- 6.8 cm, body weight = 68.2 +- 10.8 kg) and the group 2 (healthy male subject): (n = 65, age = 16.0 +- 0.3 years, body height = 172.2 +- 6.5 cm, body weight = 65.2 +- 10.8 kg). Body composition variables (percentage of fat mass (FM), lean body mass (LBM) and ratio of extracellular to intracellular mass (ECM/BCM)) was measured with the whole-body bioelectrical-impedance analysis method (BIA 2000 M, Data Input GmbH, Germany).
The results revealed that body fat mass in well trained athletes (9.85 +- 1.98 %) was significant lower compare to and healthy male subjects 17.27 +- 4.57 % (t120 = -11.34; p0.05) between compared groups (athletes: 21.64 +- 1.56 kg.m-2, healthy subjects: 21.46 +- 3.76 kg.m-2). Optimal body composition is advisable as a predictor of movement and determinant of individual's quality of life.
Sedentary way of life leads to reduction of lean body mass and increasing of fat mass as well as ECM/BCM ratio in juvenile male subjects.
