Abstract


Objective: To investigate the effects of core strength training performed on stable (CSTS) compared to unstable surfaces (CSTU) on physical fitness in school-aged boys and girls.

Methods: 72 (36 boys, 36 girls) untrained healthy subjects (mean age: 14±1 years, age range: 13–15 years) were randomly assigned to a CSTS (n = 36; 18 boys and 18 girls) or a CSTU (n = 36; 18 boys and 18 girls) group. CSTS as compared to CSTU group were assessed on pre and post-tests. Training period lasted 6 weeks (2 sessions / week). The components of physical fitness were assessed using standing long jump test,  stand - and - reach  test,  20-m  sprint  test, jumping  sideway test and y balance  test.   

Results: This study significant in increased of components of physical fitness in both CSTS and CSTU groups (p<0.05). The increase of physical fitness for CSTU was better than CSTS (p<0.05). There are differences of physical fitness between gender in both groups (p<0.05) except for stand-and-reach test (p>0.05).

Conclusion: CSTU and CSTS increases in all components of physical fitness in youths. CSTU can improve of physical fitness better than CSTS. There are differences of physical fitness between gender in both groups except for stand-and-reach test.
