Abstract
The purpose of this study was to determine if Pilates' methods of exercise 1) increased abdominal muscle endurance 2) increased hamstring flexibility 3) enhanced posture, and 4) improved self-esteem. A single subject case study design was used. The search for subjects, aged 20-60 years, was conducted throughout the Florida Gulf Coast University population. Exclusion criteria: pregnancy, low back pain, abdominal pain, abdominal surgery in the past year, neuromuscular or autoimmune disease, and those currently exercising. The subject participated in a Pilates exercise routine consisting of a 55-minute session, 2 times each week for a total of 8 weeks, directed by a certified Pilates instructor. Measurements were taken prior to the intervention, at 4 weeks, and following 8 weeks. The Straight Leg-Raising Test and the Sit and Reach Test were used to measure hamstring flexibility. The Partial Curl-up Test was used to determine abdominal muscle endurance. Digital photographs of the subject were taken in standing in the sagittal and frontal planes to examine posture. To assess self-esteem, the Rosenberg Self-Esteem Scale was administered and the subject kept a journal. Findings indicate that participation in a Pilates exercise program may improve abdominal muscle endurance, hamstring flexibility, posture, and self-esteem. There is a need to conduct more controlled research using Pilates' methods because Physical Therapists are incorporating these methods into their treatment plans.
