Brief Summary

Background: It has been demonstrated that core strength training is an effective means to enhance trunk muscle strength (TMS) and athletic performance in youth. However, the role of instability with core strength training is unresolved in youth. This study specifically will investigate the effects of core stability (CST) compared to core instability strength training (CIST) on physical fitness in adolescents. Methods: Twenty-seven (14 girls, 13 boys) healthy adolescents (age 14±1 years) will be assigned to a CST (n=13) or a CIST (n=14) group. Both training programs will last 6 weeks (2 sessions/week) and included frontal, dorsal, and lateral core exercises. During CIST, these exercises will be conducted on unstable surfaces (e.g., TOGU© DYNAIR CUSSIONS, THERA-BAND© STABILITY TRAINER). Expected Results: Based on selected results reported in the literature, we hypothesize that participants performing CIST as compared to CST will show larger improvements in physical fitness tests (i.e., strength, speed, flexibility, coordination, balance) following training. Of note, training induced gains in strength, speed, flexibility, coordination, and balance are of vital importance for sports performance, everyday activities, and injury prevention.

Interventions

core strength training BEHAVIORAL

Both training programs will last 6 weeks and comprise 2 training sessions per week with a total of 12 training sessions for each intervention group. Each training session will last 30 min, starting with a brief warm-up program mainly consisting of core strength exercises at moderate intensities and ending with a cool-down program (i.e., dynamic stretching). During the main part of training, both groups mainly conduct the "big 3" exercises as described by McGill. These will include the curl-up, side bridge, and quadruped position. In other words, every single training session will consist of frontal, dorsal, and lateral core exercises. The only difference between the 2 intervention groups is that the CSTU protocol comprise core exercises that will be conducted on unstable elements (e.g., TOGU© DYNAIR PRO, THERA-BAND© STABILITY TRAINER), whereas the CSTS program will contain the same exercises on stable surface only.
