ABSTRACT:

Background: Core is the kinetic link that facilitates transfer of torques and angular momentum between lower and upper extremities.

Objective:To study the effect of core training on core strength, endurance and balance using stable vs unstable surface.

Outcome measure: Biofeedback and SERT.

 Methodology: 30 participants were divided in two groups for stable and unstable training,4 weeks intervention was carried out.

Result: statically significant improvement of core strength, endurance and balance was seen on stable and unstable surface training.

 Conclusion: Stable and unstable surface training both are effect in improving strength, endurance and balance, unstable surface training was better.
