Abstract
The window of trainability is a vital concept that should be considered by strength and conditioning coaches when designing a training plan for adolescent athletes. The aim of the study was to determine the impact of eight weeks functional high-intensity circuit training (FHICT) on muscle function, oxidative stress responses and antioxidant status in adolescent athletes.
A randomized clinical trial (IRCT20190530043762N1) with two-group pre-test and post-test design was used. Twenty adolescent soccer players (14-16 year) were divided into FHICT group (n=10) and control group (n=10). FHICT group performed functional high-intensity circuit training for eight weeks (3-times per week). Control group followed their normal soccer training with the same volume. We collected blood samples two times, once before the intervention (baseline) and the next two days after the last session. Functional tests were performed before and after the intervention. Data was analyzed by SPSS software version 23.
VO2peak and Vertical height jump were significantly higher in the FHICT group compared to the control group (P<0.05).No significant differences were found between groups for knee extensors and knee flexors isokinetic strength, mean anaerobic power, peak anaerobic power, fatigue index and maximal explosive legs power(P>0.05).In addition, the serum concentrations of 8-Hydroxydeoxyguanosine (8-OHDG), malondialdehyde (MDA), hydrogen peroxide (H2O2), and also catalase (CAT) activity in FHICT group were insignificantly lower compared to the control group (p>0.05).No significant differences were found between groups for glutathione peroxidase (GPX) at either time point (P >0.05).
Functional FHICT is a useful, time-effective and safe training method that can be used in the adolescent athlete population. Eight weeks of FHICT training may increase physical performance and reduce oxidative-induced oxidative stress in adolescent athletes.
