The research aims to know the effect of Cross training on some of the physical abilities ( muscle power of legs and arms – transition speed – accuracy – circulatory - respiratory endurance.– agility ) and also on other biochemical measurements ( Beta endorphin – lactic acid – lactate dehydrogenase ) of under 18 year basketball players .
The researchers applied the experimental methodology on a sample consists of (8) under 18 basketball players . Some of the research tools : physical tests – Biochemical measurements – cross training program .
The following statistical devices have been used: Mean – Standard Deviation – Media in – Skewness – Correlation Coefficients – T .Test – Progress Ratios .
The present research revealed that the Cross training has a positive effect with the significant level of 0.05 on the physical abilities ( muscle power of legs and arms – transition speed – accuracy – circulatory-respiratory endurance .– agility ) for under 18 year basketball players . The physical abilities ( under study ) of Under 18 year basketball players have significant improvement ranging between ( 12.23 % and 27.12 %) .
Cross training has a positive effect with significant level of 0.05 also on the biochemical variables ( Beta endorphin – lactic acid –lactate dehydrogenase ) of under 18 year basketball players , it helps to improve the biochemical variables ( under study ) with a percentage ranging between ( 4.56 % and 6.23 % ).
