The research aims to compare the effect of 10-20-30 training and 5-10-15 training on developing some of physical and physiological variables for field hockey juniors, The researchers use experimental methodology with two groups design (2 experimental groups) and pre-post measurements, The research sample was chosen in Purposive method, 24 field hockey juniors under 18 years registered in the Egyptian Hockey Federation were divided as follows (12) juniors of 10-20-30 training group, (12) juniors of 5-10-15 training group, The researchers add 10-20-30 training and 5-10-15 training programs ( 8 weeks by two training units per week) as additional training units to the basic program for the two experimental groups, the results of this study were both 10-20-30 training and 5-10-15 training has a positive effect on developing some of physical and physiological variables for field hockey juniors, and there are no statistical differences between the two experimental groups, The researchers recommend to use both 10-20-30 training and 5-10-15 trainind on developing physical and physiological variables for field hockey players and compare them with another training styles which divided from High-intensity interval training on developing functional and biochemistry adaptations for field hockey players.
