Creatinine.

The The research aims to identify the effect of the proposed hospitalization program to reduce the impact of match pressure during the competition period on some biochemical variables associated with relative muscle damage and injury rate. A sample of (16) players in the age group from (18) to (19) years, and among the means and tools of data collection are basic measurements, including height measurement, weight measurement, muscle percentage measurement, body water percentage, functional measurements, including measurement of enzymes (Cr-LDH), The results resulted in the presence of statistically significant differences between the results of the tribal measurement and the post measurement for the experimental group before and after the match, which indicates an improvement in the dimensional measurement of the experimental group from the tribal measurement before and after the match. The match with the best arithmetic mean.
