Abstract:
|
Mono-frequency (50 kHz) whole-body and
segmental bioimpedance is measured before sport training in 14
high performance athletes. The athletes are classified in two
groups according to the team sport: football and basketball.
Bioelectrical impedance vector analysis (BIVA) method is used
to obtain the individual whole-body impedance and 6 segmental
impedance vectors in the main muscular groups in the lower-
limbs. The whole-body vector is analyzed in the tolerance
ellipses of the reference population. Individual impedance
vector components are standardized by the height H of the
subject, (R/H and Xc/H) to obtain the impedance vector (Z/H)
of each segment. The hypotheses of the study are: 1) Not all the
sports have the same pattern of bioimpedance vector by muscle
group. 2) In elite well trained athletes their muscle groups are
symmetrical (right and left sides), thus each athlete is its own
reference for future comparisons. 3) We expect a change in the
two components of bioimpedance vector (R/H and Xc/H) in
front of a muscle injury. In order to compare the differences
between the complex Z/H vector (R/H, Xc/H) we use Hotelling s
T2 test. Preliminary results show a significant difference (P <
0.05) in bioimpedance vectors between groups according to the
team sport, and also between normal muscle condition and after
muscle injury producing hyper-hydration. |
