Effects of High-Intensity Training and Resumed Training on Macroelement and Microelement of Elite Basketball Athletes
Lijuan Wang Biol Trace Elem Res (2012) 149:148–154
The purpose of this study was to assess the effects
of high-intensity training and resumed training in hot and
humid environment on plasma macro- and microelements
levels of elite Han Chinese basketball players. Ten welltrained
elite basketball athletes’ plasma macroelements
(chlorin, sodium, potassium, and calcium), creatine kinase
(CK), and creatine kinase-MB (CK-MB) were measured
before and after a 2-h high-intensity training, and microelements
(zinc, copper, iron, and selenium) were determined
before and after a 1-week high-intensity training and after a
1-week resumed training. The blood CK and CK-MB levels of
the elite basketball athletes were significantly increased
(P<0.05) after high-intensity basketball training.
The macroelements (chlorin, sodium, and calcium) levels of blood increased significantly except potassium after high-intensity
basketball training. No significant differences (P>0.05) were
found in zinc and copper levels; nevertheless, the levels of
plasma selenium and plasma iron were significantly lower
(P<0.05) after a 1-week high-intensity training. After a 1-week resumed training, except zinc, all of microelements
measured had a trend toward original levels.
These results implicated that high-intensity training would provoke the
change of macroelements which would lead to electrolyte
disturbance. In addition, the present study suggested that a
1-week high-intensity training would have an impact on
microelement levels, especially for selenium and iron.
