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: In this study, 72 (36 males, 36 females) untrained healthy subjects
(mean age: 14±1 years, age range: 13–15 years) were randomly assigned to

a CSTS group for stable surface (n = 36; 18 males and 18 females) or a CSTU
group for unstable surface (n = 36; 18 males and 18 females). Core strength
training performed on stable as compared to unstable surfaces 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 showed significant results in increased components
of physical fitness in both CSTS and CSTU groups (p
