Abstract
The aim of the paper was to asses changes
in body composition using bioelectrical impedance
analysis (BIA) methodology in members of national
karate team after teen week preparatory training period.
The investigation was carried out on 11 male karate
contestants, aged 18 to 28 years mean age (21.82
3.58). The body composition was analyzed with In
Body 720. The BIA outcomes were divided in 3 group
of variables: body fl uid and body composition variables,
obesity diagnose variables and segmental analysis
variables. All BIA variables were insignifi cantly
higher at second measuring (p>005). Only Body mass
index (BMI=24.1 vs 24.55); mineral (4.69 kg vs 4.77
kg) and osseous (3.85 kg vs 3.92 kg), were signifi -
cantly higher (p≤0.05) after preparatory period. Body
fat mass (BFM=10.34 kg vs 10.75 kg, p=0.329) and
body fat percent (BF%= 12.73 vs13.22%) insignifi -
cantly increased after preparatory period. The skeletal
mass has changed from 40.03kg to 40.55kg (p=0.276).
Body composition analysis, changes in weight, BMI
and body fl uids are essential for weight categories
dependent sports such as karate. Positive changes in
body components and in body fl uids suggest that the
training process during the preparatory period did not
show negative effects on body components and the hydration
of the karate athletes.
