[Changes of peripheral blood parameters in aerobic dance instructors after aerobic dance instruction].
To investigate the biological load of aerobic dance instruction on the body, a blood biological study was performed on 13 female instructors. The values were compared with 10 female healthy controls. The results obtained were as follows. 1. A significant negative correlation was observed between the total experience of aerobic dancing (in years) and the levels of serum phospholipids. In addition, the numbers of white blood cells and the levels of serum phospholipids, lipoperoxide, uric acid and creatinine were significantly related to aerobic dance instruction time (years). 2. The levels of serum CPK, aldolase, GOT, BUN and creatinine in the aerobic dance instructors were significantly higher than those in the controls. 3. The levels of serum CPK, uric acid, BUN, creatinine and Ca increased significantly after an intermediate class lesson (about 60 minutes). In addition, the numbers of white blood cells also increased after the lesson, but not significantly. Moreover, Significant decreases of the mean corpuscular volume and serum Mg were observed after the lesson.
