The aim of the present study was to examine the effect of
in-season strength maintenance training frequency on strength,
jump height, and 40-m sprint performance in professional soccer
players. The players performed the same strength training
program twice a week during a 10-week preparatory period. Inseason,
one group of players performed 1 strength maintenance
training session per week (group 2 + 1; n = 7), whereas the other
group performed 1 session every second week (group 2 + 0.5;
n = 7). Only the strength training frequency during the in-season
differed between the groups, whereas the exercise, sets and
number of repetition maximum as well as soccer sessions were
similar in the 2 groups. The preseason strength training resulted
in an increased strength, sprint, and jump height (p , 0.05).
During the first 12 weeks of the in-season, the initial gain in
strength and 40-m sprint performance was maintained in group 2
+ 1, whereas both strength and sprint performance were
reduced in group 2 + 0.5 (p , 0.05). There was no statistical
significant change in jump height in any of the 2 groups during
the first 12 weeks of the in-season. In conclusion, performing 1
weekly strength maintenance session during the first 12 weeks
of the in-season allowed professional soccer players to maintain
the improved strength, sprint, and jump performance achieved
during a preceding 10-week preparatory period. On the other
hand, performing only 1 strength maintenance session every
second week during the in-season resulted in reduced leg
strength and 40-m sprint performance. The practical recommendation
from the present study is that during a 12-week
period, 1 strength maintenance session per week may be
sufficient to maintain initial gain in strength and sprint
performance achieved during a preceding preparatory period.
