Comparison of the Immediate Effects of a Hypopressive Abdominal Exercise Program Versus a Proprioceptive Neuromuscular Facilitation Stretching Program on Hamstring Flexibility in Adults With Short Hamstring Syndrome

A Randomised Controlled Trial was conducted to assess increases in hamstring flexibility using two different methods, one group of participants who were stretched with PNF techniques and the other group who performed Hypopressive Abdominal Techniques (HAT). Flexibility scores of both groups were obtained and compared using pre and post measurements of a single intervention.
