Effects of Active Stretching on Cardiovascular Response and Arterial Stiffness in Older Adults With Low Flexibility

"Participants in the intervention group performed active static stretching exercises using a pictorial exercise booklet. The booklet contained a series of self-directed stretching postures targeting major muscle groups. Each stretch was held in a static position without external assistance, encouraging the participant to engage and maintain the stretch voluntarily.~Each stretch was held for 30 seconds and repeated 3 times per muscle group. The targeted areas included the hamstrings, quadriceps, calves, hip flexors, and shoulders."
