The study aims to identify the impact of varying intensity physical loads on the level of blood proteins , liver enzymes ,kidney function and the rate of change of each blood proteins , liver enzymes and kidney functions during players exposure to physical loads (medium - Lower than maximum - maximum).
The study sample contains 10 wrestlers in the age 9:12 year old and the experimental method was used, the most important results indicated that medium load leads to a slight decrease in blood proteins and cause a small increase in liver enzymes and kidney function while lower than maximum and maximum loads lead to increasing in blood proteins, liver enzymes and kidney function levels.
