The Changes on Creatine Kinase in Response to Aerobic Exercise among Novice and Trained Soccer Players of Different Ages

The Impact of Soccer Match Play on the Muscle Damage Response in Youth Female Athletes

“…Post hoc analysis determined statistical differences between the U15 and U17 groups only (P < 0.01). VAS (cm) pre-and post-match play per age group [8,30,32]. This is in contrast to previous reports highlighting youth populations as low CK responders compared to adult populations [19] due to a potentially greater resistance to fatigue during exercise [7].…”

“…Therefore, it was suggested that the higher baseline values reported may be attributed to the increased exposure to exercise demonstrated in the trained group [12]. Furthermore, greater muscle mass has also been highlighted as a potential influential factor to greater baseline CK values [8]. Therefore, as this is one of the first studies to investigate the muscle damage response in elite female youth populations the lower baseline CK activity is can be attributed to youth female players having lower exposure to training, combined with smaller muscle mass make this study's data supportive of the research in adult elite females [1,12] and trained pre-pubescent boys [8].…”

“…Therefore, although greater peak CK values were reported [12], the actual CK increase was lower than that in the current study. It has been previously suggested that training status can impact an individual's response to exercise [3], with trained individuals demonstrating higher baseline values, and a lower exercise-induced increase in muscle damage compared to untrained individuals [8]. Regular exposure to physical activity may develop protective mechanisms to withstand structural damage to the muscle [8].…”

Does Child have Muscle Pain after Enormous Exercise?

“…The rate of change of VAS and ROM in children was significantly lower than in male adults (p<0.05). Webber et al [12] present that male adults exert greater muscle activity and strength per unit area, resulting in greater muscle cell damage, increased CK, and decreased IMS. Therefore, boys…”

“…Webber et al [12] compared the effects of downhill running on VAS and CK between boys and male adults and girls and male adults. VAS was significantly increased in all four groups after downhill running.…”
