Relationship Between Body Size and Skeletal Age with Muscle Damage in Young Soccer Players
This study verified the relationship between body size and skeletal age (SA) with
the behavior of blood markers of muscle damage and delayed onset muscle soreness
(DOMS) after a soccer match in the U-13 and U-15 categories. The sample
consisted of 28 soccer players in the U-13 and 16 in the U-15 categories.
Creatine kinase (CK), lactate dehydrogenase (LDH), and DOMS were evaluated up to
72 h after the match. Muscle damage was elevated at 0 h in U-13,
and from 0 h to 24 h in U-15. DOMS increased from 0 h to
72 h in U-13 and from 0 h to 48 h in U-15. Significant
associations of SA and fat-free mass (FFM) with muscle damage markers and DOMS
were observed only in U-13, specifically at time 0 h, when SA explained
56% of CK and 48% of DOMS and FFM explained 48% of DOMS.
We concluded that in the U-13 category, higher SA is significantly associated
with muscle damage markers, and increase in FFM is associated with muscle damage
markers and DOMS. Furthermore, U-13 players need 24 h to recover
pre-match muscle damage markers and more than 72 h to recover DOMS. In
contrast, the U-15 category needs 48 h to recover muscle damage markers
and 72 h to recover DOMS. [...] Georg Thieme Verlag Rüdigerstraße 14, 70469 Stuttgart,
