Aims of the randomized controlled study is compare to the effects of external and internal focus strategies, commonly used in Pilates, on participants' reaction time and performance metrics. Conducted over an 8-week Pilates program at Alanya Alaaddin Keykubat University, we plan to include 25 participants in each focus group. Participants in the external focus group will use equipment to perform exercises, while the internal focus group will perform exercises with attention to body positioning.

The primary aim of this study is to examine the difference in effects between 8-week internally and externally focused Pilates exercises on the performance of young sedentary individuals. A secondary aim is to investigate the effects of internally and externally focused Pilates exercises on the physical characteristics and reaction time of young sedentary individuals.
