Sprint, change of direction, jump performance
plays a major role in success of field-based
team sports such as football. This study aims
to indicate the relationship between linear
sprint (10m, 30m), change of direction (HUFA
with and without ball), vertical jump (CMJ) and
power (peak power, peak average) parameters
in 11-12 years old football players. Thirty-six
male football players (average of age
12.55±0.50 years, standing height average
155.63±9.34 cm, body weight average
46.57±8.15, average of years of training
3.58±0.96) from U12 and U13 categories of a
football team in Turkish Super League
participated in this study. Normality of the data
was analysed with the Shapiro-Wilk test and
homogeneity of variance was analysed with
the Levene test. Statistical analysis of the data
obtained were carried out by Pearson
Correlation Test as the data was parametric.
Statistical significance was accepted as
p<0.05. According to the findings, a highly
negative significant correlation was found
between 10 m and 30 m linear sprint with peak
power and average power (p<0.01). There was
a moderate, negative significant correlation
between change of direction without ball
performance and average power (p<0.05).
Moderate, negative significant correlation
between HUFA change of direction with ball
performance and average power was also
found (p<0.05). Consequently, leg strength is
important and trainings should include drills to
improve the leg strength, if sprint speed,
maximal speed and quick change of direction
speed of the football players in this age group
are desired to be improved.
