				        	 Purpose:This study aims to compare the effect on balance during core and ankle muscle strengthening exercises using the Thera-Band. 
				        	
				        
				        	Methods:21 healthy college students were recruited. The participants were divided into a core strengthening group (CSG), an ankle strengthening group (ASG), and a non-exercise group (NEG). CSG and ASG were performed twice a week for a total of 4 weeks, and static and dynamic balance were measured before and after the intervention. The static balance were measured as stability index and weight distribution index using Tetrax®. The dynamic balance was measured in each direction by the Y balance test. The Thera-Band intensity was increased after 2 weeks of exercise, and the exercise was subsequently performed. 
				        	
				        
				        	Results:Participants showed static balance with Tetrax®, a significant difference was noted between normal eye closes and pillow with eye closes in ASG (p < 0.05). In the case of dynamic balance with the Y balance test, a significant difference was observed in posterolateral direction (PL) and composite score (CS) between each group for the pre- and post-intervention differences (p < 0.05). A significant difference was observed between PL and CS in CSG (p < 0.05). 
				        	
				        
				        	Conclusion:These findings show that the progressive Thera-Band exercise had a positive effect on balance abilities. It was confirmed that core strengthening was effective for dynamic balance, and ankle strengthening was effective for static balance.
