AIM: Aim of the study is to find the effect of Swiss ball and Thera Band exercises on muscle endurance in healthy individuals in age group of 18-25 years. OBJECTIVES: To study the effect of Swiss ball exercises on muscle endurance in healthy individuals in age group of 18-25. To study the effect of Thera band exercises on muscle endurance in healthy individuals in age group of 18-25 years. To compare the effect of Swiss ball and Thera band Exercises on muscle endurance in healthy individuals in age group of 18-25 years. METHODOLOGY: In this comparative study 50 subjects in the age group of 18-25 years who fulfilled the inclusion criteria were recruited from MVP’S College of Physiotherapy. Subjects were then were divided into two groups- Group A- Swiss ball exercises and Group B – Thera band exercises. Then the treatment was given once a day for 4 times per week for 4 weeks with 10 repetitions and a 10-second hold. Outcome measures of Curl up test and Modified Sorensen Test were evaluated before and after treatment session. RESULT: ANOVA was found extremely significant when the data was compared within the group. And unpaired t test was found significant when data was compared between the groups. CONCLUSION: The study concluded that Thera band exercises are more effective than Swiss ball exercises in terms of improving muscle endurance in the age group of 18-25 years.
