This research aims to investigate the effectiveness of a suggested qualitative training program on some physiological responses and skillful variables for 17 old-football juniors through examining the effectiveness of the suggested qualitative training program on some physiological responses and the skillful variables for 17 old-football juniors. Another purpose of this research is to examine the rate of progress of some physiological responses and some in question skillful variables for under 17 years –old junior footballers.
The researcher used the experimental method as it suited for the content and procedures of the research through which he used the experimental design of one- experimental group (pre and post tests.
The population study represents (87) junior football players of (4) clubs under the age of 17 at El-baha district that are (El-baha,El-ameed, Al-seraah and Al-tasamouh) clubs in the Kingdom of Saudi Arabia.these clubs are registered in the records of Football Saudian union in the current season 1433 -1434 H. The researcher selected the research sample using deliberate method from17- years old junior-football players at El-tasamouh sport club, Al-Qunfudah Governerate. The sample size was (18) junior players in addition to the survey research sample which were (8) junior players bringing the total sample (26) junior players. The researcher conducted and examined the homogeneity of the research sample in the in questioned- variables to ensure its normal distribution curve.
The researcher used the following physiological measurements to collect data as follows: heart rate ( FH), maximal oxygen consumption (VO2), volume of ventilation(VE-ED), Respiratory fitness variable ( Mets), and the following skilful tests as : Wind run with a ball, internal facet of foot, kicking the ball with the external facet of foot, trap the ball with the front facet of the foot, chest trap, fix the ball under foot, Kicking the ball with head from a fixed position.
One of the prominent results is that the suggested qualitative training program has a positive effect with a statistical significance on the development of physiological responses and developing the level of skilful performance of research sample of football juniors under the age of 17.,also there is an improvement rate between the pre- and post measurements in favor of the post measurement in all physiological measurements and skilful tests of research sample.
