This study was designed to clarify the effects of a 10 month-training program on the physique and
physical fitness in soccer players of a Japanese professional soccer club, that consisted of 11 junior
youth players with a mean age of 12 . 6 years and more than 4 years of soccer experience. The team
of trained 7.5 hours per week and played at least one soccer game per week. Measurements of
physique and physical fitness were done for body height and weight, subcutaneous fat thickness,
isokinetic knee extension and flexion strengths at the speed of 60°/s of each leg, Ieg extension
power, 30 m and 50 m dashes, and V02max. These measurements were carried out in December 1997
and October 1998. The body height and weight significantly increased and subcutaneous fat thick-
ness decreased. The isokinetic strengths and leg extension power, 30 m and 50 m dashes, and V02
max significantly improved. However, some isokinetic strengths, Ieg extension power and V02max
relative to body weight significantly decreased. The results suggested that the training program was
very effective to increase body mess but only maintained the level of muscular and endurance
ability during adolescence.
