Each intervention type is written on a card and placed in a sealed envelope. Participants are listed in the order of their enrollment in the study. After each participant is enrolled, the envelopes are shuffled randomly, and each participant is asked to select one envelope at random. The number of envelopes is determined based on the expected sample size, ensuring that each selected envelope is not re-entered into the randomization process. This method ensures that the number of participants in each experimental group is approximately equal, thereby reducing the risk of discrepancies in group sizes. N/A Flexible Flatfoot. Intervention 1: Intervention group: The eccentric/concentric-biased groups will perform the exercises for six weeks, three days per week, each lasting 20 to 40 minutes. A warm-up period of 5–10 minutes will be conducted before each session, followed by a 5–10-minute cool-down after the exercises. In eccentric-biased training, the emphasis will be on the eccentric phase of the exercises, whereas in concentric-biased training, the focus will be on the concentric phase. The exercises included in this study are heel raises, the short foot exercise, and great toe (hallux) flexion. The tempo for eccentric-biased exercises will be set at 2-0-4, while for concentric-biased exercises, it will be 4-0-2. Exercise progression will follow a structured sequence, starting from a seated position, advancing to a standing position with both feet and finally to a single-leg standing position. Intervention 2: Control group: The control group did not receive any intervention during this period and continued with their routine daily activities.
