Abstract
The capacity to recover
from intense training and matches is considered an important determinant in
soccer performance. At present, there is no consensus on the effect of
posttraining recovery interventions on subsequent training session. The aim of
this study was to determine the effectiveness of active (12 minutes of
submaximal running and 8 minutes of static stretching) and passive recovery (20
minutes sit on a bench) interventions performed immediately after a training
session on muscle contractile properties using tensiomyography (TMG) and
perceived muscle soreness 24 hours after the training. During 2 experimental
sessions, 31 professional soccer players participated in a randomized fully
controlled trial design.
The first session was designed to collect the player's
TMG and muscle soreness measurements (pretest). After baseline measurements,
the participants performed a standardized soccer training during which the
heart rate (HR) and rating of perceived exertion (RPE) were recorded to
evaluate the training load. At the end of training unit, all the players were
randomly assigned to the active recovery group and the passive recovery group.
A second experimental session was organized to obtain the posttest values. The
players performed the same test, administered in the same order than in the
first trial. The results showed that no differences between groups were
observed in the HR and RPE. No significant effect because of recovery strategy
was found on TMG parameters and perceived muscle soreness.
This study showed how soccer players preformed in the
next training session. One group did
cool down exercises and stretches for 20 minutes and the other group did not do
any cool down. The study suggest in the
next practice session the player from both groups preformed about the
same. Showing that cool down did not
affect the following sessions performance or perceived muscle soreness.
